3HAB8101-8/08Y串行链路模块
ROM校验和检查此测试验证ROM存储器的校验和。差异导致ICT模块状态LED呈红色，ICT模块停止运行。实用程序图4-4（INICT01模块）和4-5（INICT3模块）所示的实用程序菜单可通过将诊断监视器连接到ICT模块终端设备的端口2来获得。通过ICT模块双列直插式开关启用此选项。实用程序菜单选项的说明如下：TALK90选项选择此选项将显示计算机界面可用的所有命令的菜单。图4-6显示了TALK90命令菜单的示例。ICT模块必须联机才能使用大多数这些命令。使用RESTART命令将ICT模块联机。要执行RESTART命令，如果计算机界面工作正常，将再次显示实用程序菜单。选择TALK90继续。ICT模块上的CPU LED将显示发送和接收的命令和回复计数。然后，NIS模块应联机，计算机接口将能够与INFI-NET节点通信。实用程序菜单将再次出现。选择TALK90继续。使用TALK90菜单上的任何可用命令检查系统。配置/查看呼叫密码选项选择此选项可查看和/或更改密码。此选项显示以下信息：当前密码：1 2 3 4 5 6 7 8
注：此选项定义ICT端口的密码。要使用此功能，必须启用ICT模块上的密码保护选项（位置5，双列直插式开关U72）。
计算机命令/回复序列选项
此选项启用后，会使计算机接口在终端上以十六进制格式回显计算机命令和答复。串行端口上的命令前面是CS；串行端口上的应答前接一个RS。并行端口上的命令前接一条CP，并行端口上应答前接RP。按3可打开和关闭此功能。图4-7显示了RESTART命令后接DEMAND MODULE STATUS命令的示例。注：此选项减慢计算机接口响应时间，不使用时应禁用。对提示回答Y将显示TIME Utilities（时间实用程序）菜单。有关时间实用程序菜单的示例，请参见图4-8。选择所需功能并按照屏幕提示完成任务。对提示回答N会使终端返回到实用程序菜单。监视器模式选项选择此选项可启用或禁用监视器模式。启用时，计算机接口将忽略来自终端或主机的所有控制命令。终端或主机只能监视数据。选择此选项（仅限INICT01模块）可切换暂停时转储功能。如果启用了暂停转储，ICT模块将在发生致命错误时将相关系统数据转储到ICT模块NVRAM（ICT模块状态LED将为红色）。合格的贝利控制公司人员可以使用这些数据来确定模块故障的原因。
ROM Checksum Check
This test verifies checksums of the ROM memory. Discrepancies cause the ICT module status LED to go solid red and the ICT module operation halts. UTILITIES The utilities menu shown in Figures 4-4 (INICT01 module) and 4-5 (INICT03 module) is available by attaching a diagnostic monitor to port two of the ICT module termination device. Enable this option through the ICT module dipswitches. Description of the utilities menu options follow: TALK90 Option Selecting this option displays a menu of all the commands available to the computer interface. Figure 4-6 shows an example TALK90 COMMAND MENU. The ICT module must be on-line to use most of these commands. Use the RESTART command to put the ICT module on-line. To execute the RESTART command,If the computer interface is functioning properly, the utilities menu will appear again. Select TALK90 to continue.The CPU LEDs on the ICT module will display the count of commands and replies that were sent and received. The NIS module should then go on-line and the computer interface will be able to communicate to INFI-NET nodes. The utilities menu will appear again. Select TALK90 to continue. Use any of the available commands on the TALK90 menu to check the system. Configure/View Callup Password Option Selecting this option allows the password to be viewed and/or changed. The following information is displayed by this option: Current Password: 1 2 3 4 5 6 7 8
NOTE: This option defines the password for the ICT ports. To use this feature, the password protection option (position 5, dipswitch U72) on the ICT module must be enabled.
Computer Command/Reply Sequences Option
This option, when enabled, causes the computer interface to echo computer commands and replies in hexadecimal format on the terminal. Commands on the serial port are preceded by a CS; replies on the serial port are preceded by an RS. Commands on the parallel port are preceded by a CP, and replies on the parallel port are preceded by a RP. Pressing 3 toggles this feature on and off. Figure 4-7 shows an example of a RESTART command followed by a DEMAND MODULE STATUS command. NOTE: This option slows computer interface response time and should be disabled when not in use.Answering Y to the prompt causes the TIME Utilities menu to be displayed. See Figure 4-8 for an example time utilities menu. Select the desired function and follow the screen prompts to complete the task. Answering N to the prompt causes the terminal to return to the utilities menu. Monitor Mode Option Selecting this option enables or disables the monitor mode. When enabled, all control commands from the terminal or the host computer are ignored by the computer interface. The terminal or host computer can monitor data only Selecting this option (INICT01 modules only) toggles the dump on halt feature. If dump on halt is enabled, the ICT module will dump pertinent system data to the ICT module NVRAM upon a fatal error (the ICT module status LED will be red). This data can be used by qualified Bailey Controls Company personnel to determine the cause of a module failure.
