3HAB8101-8/08Y串行鏈路模塊
ROM校驗和檢查此測試驗證ROM存儲器的校驗和。差異導(dǎo)致ICT模塊狀態(tài)LED呈紅色，ICT模塊停止運行。實用程序圖4-4（INICT01模塊）和4-5（INICT3模塊）所示的實用程序菜單可通過將診斷監(jiān)視器連接到ICT模塊終端設(shè)備的端口2來獲得。通過ICT模塊雙列直插式開關(guān)啟用此選項。實用程序菜單選項的說明如下：TALK90選項選擇此選項將顯示計算機(jī)界面可用的所有命令的菜單。圖4-6顯示了TALK90命令菜單的示例。ICT模塊必須聯(lián)機(jī)才能使用大多數(shù)這些命令。使用RESTART命令將ICT模塊聯(lián)機(jī)。要執(zhí)行RESTART命令，如果計算機(jī)界面工作正常，將再次顯示實用程序菜單。選擇TALK90繼續(xù)。ICT模塊上的CPU LED將顯示發(fā)送和接收的命令和回復(fù)計數(shù)。然后，NIS模塊應(yīng)聯(lián)機(jī)，計算機(jī)接口將能夠與INFI-NET節(jié)點通信。實用程序菜單將再次出現(xiàn)。選擇TALK90繼續(xù)。使用TALK90菜單上的任何可用命令檢查系統(tǒng)。配置/查看呼叫密碼選項選擇此選項可查看和/或更改密碼。此選項顯示以下信息：當(dāng)前密碼：1 2 3 4 5 6 7 8
注：此選項定義ICT端口的密碼。要使用此功能，必須啟用ICT模塊上的密碼保護(hù)選項（位置5，雙列直插式開關(guān)U72）。
計算機(jī)命令/回復(fù)序列選項
此選項啟用后，會使計算機(jī)接口在終端上以十六進(jìn)制格式回顯計算機(jī)命令和答復(fù)。串行端口上的命令前面是CS；串行端口上的應(yīng)答前接一個RS。并行端口上的命令前接一條CP，并行端口上應(yīng)答前接RP。按3可打開和關(guān)閉此功能。圖4-7顯示了RESTART命令后接DEMAND MODULE STATUS命令的示例。注：此選項減慢計算機(jī)接口響應(yīng)時間，不使用時應(yīng)禁用。對提示回答Y將顯示TIME Utilities（時間實用程序）菜單。有關(guān)時間實用程序菜單的示例，請參見圖4-8。選擇所需功能并按照屏幕提示完成任務(wù)。對提示回答N會使終端返回到實用程序菜單。監(jiān)視器模式選項選擇此選項可啟用或禁用監(jiān)視器模式。啟用時，計算機(jī)接口將忽略來自終端或主機(jī)的所有控制命令。終端或主機(jī)只能監(jiān)視數(shù)據(jù)。選擇此選項（僅限INICT01模塊）可切換暫停時轉(zhuǎn)儲功能。如果啟用了暫停轉(zhuǎn)儲，ICT模塊將在發(fā)生致命錯誤時將相關(guān)系統(tǒng)數(shù)據(jù)轉(zhuǎn)儲到ICT模塊NVRAM（ICT模塊狀態(tài)LED將為紅色）。合格的貝利控制公司人員可以使用這些數(shù)據(jù)來確定模塊故障的原因。
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.
