The CoBox Micro will not save this learned IP address permanently; this procedure is intended as a temporary measure to allow an administrator to Telnet into the CoBox Micro for configuration.
Steps 4 and 5 have to be preformed quickly after each other. The recommended method for configuration is Telnet. For more information about using DeviceInstaller, refer to the manufacturer documentation.
Once the port is open, choose option 0 for Server configuration. Once you are in the server configuration, you can set up the IP address, default gateway, and subnet mask to match your specific network configuration. You will also need to enter a configuration password for the device. The password can be a maximum of 4 characters only, unless enhanced password is enabled.
For more information, refer to the CoBox Micro documentation. Lenel recommends that you increase the security by enabling enhanced passwords. This allows for a maximum of 16 characters in the password. After the Server configuration is complete, choose option 1 for Channel 1 configuration. Make the following changes in the configuration menu: 1. The changes will be stored in the CoBox Micro and the connection will be terminated.
To verify that the changes were stored correctly, cycle the power on the CoBox Micro and when it has rebooted, go to the command prompt and Telnet to the IP Address that was just given to the device and port example: TELNET The configuration page will display a summary of current settings. Verify that all settings are configured properly and exit the Telnet session. Past installations may have contained vulnerabilities which could lead to unauthorized access to the CoBox Micro The recommended security settings are not necessary for the unit to work correctly; however, they are highly recommended to bridge any security gaps left open from previous installations.
Beyond securing the following internal settings of the Lantronix CoBox Micro , networking firewalls should be used to mask services that should not be publicly exposed.
Many security problems can be avoided if servers and networks are appropriately configured. Enhanced Password By default, the Cobox Micro does not have a password assigned. In Server Options, you may assign a four-digit password. While a 4-digit password is a step toward securing the unit, it is highly recommended to enable Enhanced Passwords, which will allow for a maximum of 16 digits. This can be set under Security option 6. Disabling this port prevents unauthorized access to this unit. If this is not done, it is possible to find this open port using a port scan tool.
In addition, any networked user who installs DeviceInstaller on their machine may be able to change settings to the unit. Web Server After configuration is completed, it is recommended that you disable Web Server. While it is helpful to configure the unit via the Web Server, it does not support enhanced password protection. So it is a good idea to turn this feature off. To ensure that enhanced security is in place, download the latest firmware.
Download the latest firmware from the Lantronix website, www. Upgrading Firmware via DeviceInstaller Use the correct version of DeviceInstaller with the correct version of the firmware.
For more information, refer to the DeviceInstaller documentation. NET Framework version 1. If there are devices present but they are not detected by the software, you must assign an IP address to it. If it is already configured but still does not show up in the DeviceInstaller search, verify that port 77FE is enabled. After the firmware upgrade has been completed, disable port 77FE to prevent unauthorized access to this device. Otherwise, the device should show up in DeviceInstaller.
To upgrade the firmware: 1. The Device Upgrade Wizard will appear. Select Create a custom installation by specifying individual files. Click [Next]. Enter the path for the downloaded firmware by either typing it in or clicking [Browse].
You may save this installation for later use, if you wish, by clicking [Save Installation]. This is particularly useful for upgrading multiple devices. After the update completes successfully, the device will reboot and there will be a temporary loss of communication to the ISC. If communications are not restored, power down the ISC for at least 10 seconds, then power it up once again.
Before upgrading, verify communication with the device. A change was made to the device during production that will cause the following problems. In all cases, Lantronix and our Quality Assurance Group have confirmed that removal of Pin 10 will eliminate all communication failures due to power cycling. Setup and unit configuration remain the same as as documented. Using an ESD grounding strap, ground yourself and remove the Micro from the anti-static bag or the housing.
The machine must have the following installed:. A straight through cable is required. The Connection Description window will open with the New Connection setting. The following will appear on the screen version and serial numbers may be different :. The CoBox devices current configuration will be displayed. It will look similar to the following:. Enter the IP address for the CoBox device in the form of The currently configured address will appear as you get to each part of the IP address as you are typing; just continue to type the new number.
The software will next ask you if you wish to set the gateway. Answer yes and type the gateway IP address just as you did for the IP address of the device. As it did for the devices IP address, the current configuration information will display at each segment of the IP address. You now need to enter a subnet mask.
You CANNOT enter a number here as you are used to, you must use the following table to determine what to type into this field. You will be prompted to change the Telnet configuration password. Answer Yes to the prompt. Enter SYST for the password when prompted. When asked to use a token-ring administered address answer NO. You will now be at the setup screen.
Make sure the information displayed at the top matched the information you just typed into the unit. For each item, enter the following value:. You will now be back at the setup screen.
For each item, enter the following value. The device is now configured to work with the network. Power the machine down, connect it to the network, and then power it up.
This is the same IP address that was entered in Step 1, procedure number Verify that the panel came online. RXD IN 4. GND 6. CTS IN 7. For RS communication, jumpers must be configured properly. To configure the server and channel 1, refer to the following screen shots.
Information is available for hexidecimal values. See Commonly Used Valueson page To configure this Lantronix device, perform the following procedures. You may configure through a telnet connection over the network, or a terminal program over a serial connection.
For more information, refer to the Lantronix User Guide. These instructions also apply for the CoBox-FL, with the exception of encryption. Encryption is not available on the CoBox-FL.
Encryption using the Lantronix SDS is supported only for third-party devices, and not Lenel access panels. Ensure that encryption is turned off for use with Lenel access panels. Select the option which you would like to change and type in the new value. If you would like to just confirm the current setting, do not type anything.
IP Address. The IP address must be set to a unique value in the network. The current value displays in parentheses. Gateway IP Address. The gateway address, or router, allows communication to other LAN segments. The gateway address should be the IP address of the router connected to the same LAN segment as the unit. The gateway address must be within the local network. The default setting is N No , meaning the gateway address has not been set.
To set the gateway address, type Y and enter the address. Netmask: Number of Bits for Host Part. A netmask defines the number of bits taken from the IP address that are assigned for the host part. The unit prompts for the number of host bits to be entered, then calculates the netmask, which appears in standard decimal-dot notation for example, The default setting is 0.
Change telnet config password. Setting the telnet configuration password prevents unauthorized access to the setup menu through a telnet connection to port or through web pages. The password must have four characters. The default setting is N No. You do not need a password to access the Setup Mode window by a serial connection.
This setting is optional. You will need to configure the serial port to communicate with the third party hardware devices. Some of the characters need to be entered in hexadecimal notation. Select 1 for Channel 1 define how the serial port responds to network and serial communications. The unit and attached serial device, such as a modem, must have matching speed or baud rates to use for the serial connection.
Valid baud rates are , , , , , default , , , , , and baud. The default setting is 4C. The default setting is See Common Flow Control Valueson page Port No. The port number setting represents the source port number in TCP connections. It is the number that identifies the channel for remote initiating connections. The default is port The range is This should always be set to in order to communicate with third party hardware devices.
Connect Mode. Connect Mode defines how the unit makes a connection, and how it reacts to incoming connections over the network. The default setting is C0 and should be used to communicate with third party hardware devices.
The following may be left at default settings:. When the configuration is complete, type 9 in the Change Setup menu to save your settings and exit. The device will reboot. Or, to exit without saving any of your changes, type 8.
Using a Terminal Program Use a terminal program to configure the device through a serial connection. Connect the device to a console terminal or PC running a terminal emulation program using the serial port.
The default serial port settings are baud, 8 bits, no parity, 1 stop bit, no flow control. Reset the device by cycling the unit's power turning the power off and back on. Immediately upon resetting the device, type xxx.
The easiest way to enter Setup Mode is to hold down the x key at the terminal or emulation while resetting the unit.
You must do this within three seconds of resetting the device. At this point, the screen display is the same as a telnet connection. To continue, go to step 2 under Using Telnet. Select the correct PC port and change the communication settings to baud, 8 data bit, and parity none. Refer to the manufacturer manual when entering the subnet mask information. Note: for standard class C subnet, enter an 8. Once you have finished entering all your custom network settings, type a 9 at the prompt.
This will save all your network configurations and reboot the UDS. From the connect menu, connect to the device using the IP address, Port address of , and terminal type of VT Once you are in the setup for channel 1 configuration, please make the following changes: a.
Once these settings have been properly configured, enter 9 at the prompt to save changes and exit. To verify that the device is talking on the network you can ping from the command prompt by typing ping IP address.
The cable for the UDS must be a straight through cable. The UDS custom cable must have a male connector because the fixed serial port on the device has a female adapter. Refer to the manufacturer installation manual for more information on the custom cable and pin out information. These units operate on base T. Connect to the unit via Telnet through port The Channel 1 configuration is shown below. This is for test purposes only. This may need to be changed depending on the distance of the RS line.
Refer to the Black Box manual. W17 should be on D to set 0. This is for testing purposes only. TxA and RxA must be jumpered together on the terminal strip inside the converter see diagram.
TxB and RxB must be jumpered together on the terminal strip inside the converter see diagram. ISC panels can be multidropped on the RS line using this configuration. Follow typical EOL termination. Refer to the following diagram for dial-up configuration. They are located on the back of the modem. Dial security including dial back authorized callers and modems are verified prior to passing a remotely originating call.
Dial back can also be initiated based on device configuration. For more information, refer to the US Robotics documentation. For the access control software to function properly, the DIP switches must be configured as follows. Once the modem is set up, you must send the following AT command sequences for the modem to work with the access control software. Refer to the following diagram for wiring the modem and panel. The modem can be set to dumb mode or smart mode using the two-pin jumper located on the back panel of the modem.
Use a jumper to connect the two pins for dumb mode. For smart mode, leave them off unconnected. The default setting for Lenel hardware is smart mode. When the modem is in dumb mode, it operates as though it has no command mode. When the modem is powered on or reset, it will go directly into the mode of operation for which it has been configured.
The purpose of dumb mode is for leased lines and special dial applications. If the modem is in dumb mode and it becomes necessary to reconfigure it, remove the dumb mode jumper and then cycle power to the modem. It will then be in command smart mode. This modem functions best when using DTR override with command echo disabled. The factory default setting is DTR drop causes the modem to hang up, auto-dial is inhibited.
To configure these settings, do the following: 1. For more information, refer to the Securcomm Uniflex modem operating instructions and programming manual. This diagram shows wiring downstream devices off the ISC. Three RocketPort Serial Hubs are supported. For more information, please refer to the ISC documentation.
When finished, you will need to restart the computer. In the Device Manager, expand Multi-port serial adapters. On the Advisor tab, the summary box should say Uninitialized. In the Device Control Box, click [Retrieve]. A confirmation message will be displayed. Click [Program]. Click [OK] to begin programming the device. Seek medical attention. If it gets into the eyes, flush with large amounts of water for at least 15 minutes keeping eyelids open. Spillages should be treated with A note provides additional information to supplement the main text which may help you to use and understand the product.
The prologue of each BIOS function indicates the registers used on the call and the return. For the memory size example, no parameters are passed. If a BIOS function has several possible operations, the AH register is used at input to indicate the desired operation.
For example, to set the time of day, the following code is required:. Other registers are modified on return only if they are returning a value to the caller. The exact register usage is in the prologue of each BIOS function. The vector is invoked while responding to the keyboard interrupt, and control should be returned through an IRET instruction. The power-on routines initialize this vector to an IRET instruction, so that nothing will occur when the Ctrl and Break keys are pressed unless the application program sets a different value.
Control may be retained by this routine, with the following problems. The Break may have occurred during interrupt processing, so that one or more End of Interrupt commands must be sent to the Controller. This vector points to the code to be executed on every system-clock tick. This vector is invoked while responding to the timer interrupt, and control should be returned through an IRET instruction.
The power-on routines initialize this vector to point to an IRET instruction, so that nothing will occur unless the application modifies the pointer. It is the responsibility of the application to save and restore all registers that will be modified. This vector points to a data region containing the parameters required for the initialization of the on the video card. Note that there are four separate tables, and all four must be reproduced if all modes of operation are to be supported.
The power-on routines initialize this vector to point to the parameters contained in the ROM video routines. This vector points to a data region containing the parameters required for the diskette drive. The power-on routines initialize the vector to point to the parameters contained in the ROM diskette routine.
These default parameters represent the specified values for any IBM drives attached to the system. Changing this parameter block may be necessary to reflect the specifications of the other drives attached. The dot patterns for the first code points are contained in ROM. To access the second code points, this vector must be established to point at a table of up to 1K bytes, where each code point is represented by eight bytes of graphic information.
At power-on, this vector is initialized to , and it is the responsibility of the user to change this vector if additional code points are required. This vector points to a data region containing the parameters required for the fixed disk drive. The power-on routines initialize the vector to point to the parameters contained in the ROM disk routine. These default parameters represent the specified values for any IBM fixed disk drives attached to the system.
Locations hex to contain the base addresses of any RSC cards attached to the system. Locations hex to 40F contain the base addresses of the Printer Adapter. Memory locations hex to 3FF are used as a stack area during the power-on initialization, and bootstrap when control is passed to it from power-on. If the user desires the stack in a different area, the area must be set by the application. Offset Hex Value Length Line number of current line being executed 2E 2 Line number of last error 2 Offset into segment of start of program text 30 2 Offset into segment of start of variables 2 end of program text Keyboard buffer contents 6A 1 if O-no characters in buffer if 1-characters in buffer Character color in graphics mode 4E 1 Set to 1, 2, or 3 to get text in colors 1 to 3.
Do not set to O. The programmer should not "hard code" BIOS addresses into application programs. If an error is reported by the disk or diskette code, you should reset the drive adapter and retry the operation. A specified number of retries should be required on diskette reads to ensure the problem is not due to motor start-up.
Upon completion, the programmer should restore the original environment. Failure to adhere to this practice may be incompatible with present and future applications. After the default vectors are in place, a scan for additional ROM modules takes place. At this point, a ROM routine on the adapter card may gain control. The routine may establish or intercept interrupt vectors to hook themselves into the system. A valid ROM is defined as follows:. A checksum is also done to test the integrity of the ROM module.
Each byte in the defined ROM is summed modulo hex This sum must be 0 for the module to be deemed valid. The adapter card may now perform its power-on initialization tasks. Extended ASCII encompasses one-byte character codes with possible values of 0 to , an extended code for certain extended keyboard functions, and functions handled within the keyboard routine or through interrupts.
The following character codes are passed through the BIOS keyboard routine to the system or application program. A'-1 ' means the combination is suppressed in the keyboard routine. Notes: 1. Refer to "Extended Codes" in this section. Refer to "Special Handling" in this section. Keys 71 through 83 have meaning orily in base case, in Num Lock or shifted states, or in Ctrl state.
Note that the Shift key temporarily reverses the current Num Lock state. For certain functions that cannot be represented in the standard ASCII code, an extended code is used. A character code of Nul is returned in AL. This indicates that the system or application program should examine a second code that will indicate the actual function. Usually, but not always, this second code is the scan code of the primary key that was pressed. This code is returned in AH.
The key numbers are shown on the keyboard diagram in Section 4. The following keys result in altered shift states:. This key temporarily shifts keys ,,,,55, to uppercase base case if in Caps Lock state. Also, the Shift -key temporarily reverses the Num Lock or non-Num-Lock state of keys , 75, 77, and Also, the Ctrl key is used with the Alt and Del keys to cause the system reset function, with the Scroll Lock key to cause the break function, and with the Num Lock key to cause the pause function.
The system reset, break, and pause functions are described in "Special Handling" on the following pages.
This key temporarily shifts keys , , , , and to the Alt state. Also, the Alt key is used with the Ctrl and Del keys to cause the "system reset" function described in "Special Handling" on the following pages.
The Alt key has another use. This key allows the user to enter any ASCII character code from 0 to into the system from the keyboard. The user holds down the Alt key and types the decimal value of the characters desired using the numeric keypad keys , , and The Alt key is then released.
If more than three digits are typed, a modulo result is created. Alt is handled within the keyboard routine. This key shifts keys ,, and to uppercase. Pressing the Caps Lock key a second time reverses the action. Caps Lock is handled within the keyboard routine. This key is interpreted by appropriate application programs as indicating that use of the cursor-control keys should cause windowing over the text rather than cursor movement.
Pressing the Scroll Lock key a second time reverses the action. The keyboard routine simply records the current shift state of the Scroll Lock key. It is the responsibility of the system or application program to perform the function. If combinations of the Alt, Ctrl, and Shift keys are pressed and only one is valid, the precedence is as follows: the Alt key is first, the Ctrl key is second, and the Shift key is third.
The only valid combination is Alt and Ctrl, which is used in the system reset function. The combination of the Alt, Ctrl, and Del keys will result in the keyboard routine initiating the equivalent of a system reset. System reset is handled within the keyboard routine. The combination of the Ctrl and Break keys will result in the keyboard routine signaling interrupt hex lA.
The combination of the Ctrl and Num Lock keys will cause the keyboard interrupt routine to loop, waiting for any key except the Num Lock key to be pressed.
This provides a system- or application-transparent method of temporarily suspending list, print, and so on, and then resuming the operation. The "unpause" key is thrown away. Pause is handled within the keyboard routine. The combination of the Shift and PrtSc key 55 keys will result in an interrupt invoking the print screen routine. This routine works in the alphanumeric or graphics mode, with unrecognizable characters printing as blanks.
Extended Functions The keyboard routine does its own buffering. The keyboard buffer is large enough that few typists will ever fill it. However, if a key is pressed when the buffer is full, the key will be ignored and the "bell" will sound.
Extra function keys AltA-Z Used when function starts with same letter as one of the alpha keys. Carriage return J Line feed Ctrl The address of the bytes to be read from or written to the tape is specified ES:BX and the number of bytes to be read or written is specified by ex. The number of bytes read is returned in DX.
The read block and write block automatically turn the cassette motor on at the start and off at the end. The request types in AH and the cassette status descriptions follow:. Cassette Write The write-block routine writes a tape block onto the cassette tape. The tape block is described in "Data Record Architecture" later in this section. The write-block routine turns on the cassette drive motor and a synchronization bit O and then writes the leader bytes of all l's to the tape.
Next, the routine writes the number of data. After each data block of bytes, a. Cassette Read The read-block routine turns on the cassette drive motor and then delays for about 0. After the sync bit is detected, the. If the sync byte is read correctly, the data portion can be read. If a correct sync byte is not found, the routine goes back and searches for the leader again. The data is read a bit at a time and assembled into bytes. If a CRC error is detected, the routine exits with the carry flag set to indicate an error and the status of AH set to hex DX contains the number of bytes written to memory.
Data Record Architecture The write-block routine uses the following format to record a tape block onto a cassette tape. A eRe is used to detect errors. Essentially, as bits are written to or read from the cassette tape, they are passed through the eRe register in software. After a block of data is written, the complemented value of the calculated eRe register is written on the tape.
On reading the cassette data, the eRe bytes are read and compared to the generated eRe value. If the read eRe does not equal the generated eRe, the processor's carry flag is set and the status of AH is set to hex 01, which indicates a eRe error has occurred. The routine is exited on a eRe error.
