ADCP-50-304 • Issue 19 • June 1999 • Section 2: Functional Description
alarm is thus user selectable for any one of eight leads of the lower patch port. The EIA RS-232/ CCITT V.24 modem interface signal leads are shown in Table 2-3. The alarm circuit control logic supplies the alarm signal to the control module and an alarm indicator. This logic is also controlled by the RST (Reset) touch switch, toggle switch OFF (LED off, audible alarm off), ALM (LED and audible alarm on), LED (LED on, audible alarm off), and rotary switch DLY (alarm time delay setting). The alarm may be automatically reset if the automatic alarm reset jumper is in place. LED status indicators with their color and signal definition are shown in Table 2-4. Alarm delay settings are shown in Table 2-5.
7.1Patch Interface (PSM-08)
This PS module provides interface patching. A simplified circuit showing patching is shown in Figure 2-9.
The COMPUTER patch cord jack connects directly to the chassis rear upper interface port. The MONITOR patch cord jack connects directly to the chassis rear lower interface port.
