External Interfaces, Cable Connections
2.5.5.1
Connection of Remote Control RMMC
- Dedicated line modem LGM1200MD: Connect a two wire line from RMMC to pins 1 and 2 of a
SubD, 9pin connector and connect to connector LGM1 on top of the cabinet.
NOTE:
For LGM1200MD the ends of the dedicated line (station and remote side) have to be
terminated (600 ohms/47 nF parallel). The RC combination may be soldered to the
9pin SubD connector together with the two wire line.
- Switched line modem: Connect a two wire line from PTT/RMMC to pins 1 and 2 of a SubD, 9pin
connector and connect to connector LGM1 (or LGM2, LGM3, if modem assembled) on top of the
cabinet.
2.5.5.2
Connection of a local PC or Laptop
Connect V.24 cable (0 modem cable) with SubD, 9pin from PC to connect. Local PC on top of cabinet.
2.5.5.3
Connection of Voice Signal for VAM
Connect a two wire line from RMMC to pins 1 and 2 of a SubD, 9pin connector and connect to connec
tor VAM on top of the cabinet.
2.5.5.4
Connection of auxiliary Inputs/Outputs (LCP)
The Navaids installation contains an auxiliary interface (on LCP board) with 16 optocoupler inputs and
16 optocoupler outputs for additional signals which is at the user's disposal. The external wiring of
the OIO connectors is shown in Fig. 2-27.
2.5.5.5
Connection of auxiliary Analog and Temp inputs (CSL)
Connect voltage measurement lines to plug SubD, 9pin and connect to connector ANALOG on top
of the cabinet. Connect sensor PT1000 for temperature measurement via cable and tabs to X81/1,2
or 3,4, rear BP-C. The wiring is shown in fig. 2-28.
