LBB 3510/00 PC Network card
5.2 LBB 3510/00 PC Network card
When installed into the 8-bit ISA-bus expansion slot of a personal computer (PC) running ‘Windows’
95 or 98 operating system, the PC network card provides the interface between a PC and the ‘DCN’
system. The interface card includes a headphone socket for monitoring the floor and translation
channels and an intercom handset socket for connection to an intercom handset used for vocal
communication. When connected to the DCN network its input and outputs are optically isolated.
NOTE:
1. PC control is also possible via a ‘DIRECT’ serial link between a COM-port of the DCN
control PC and Port 1 (default) or Port 2 of the CCU (LBB 3500/15, LBB 3500/35 only)
when used in ‘Single CCU mode.
2. ‘DIRECT’ PC control in Multi-CCU systems requires a serial connection between a
COM-port of the DCN control PC and a COM-port of the Master PC (OS/2) for Multi-
CCUs .
3. Simultaneous use of the PC Network card and ‘DIRECT’ PC control is NOT possible
Cable and connectors (see FIG 5-1 and FIG 5-2):
1. 3.5 mm jack-socket for operator headphones.
2. Modular jack-socket for Intercom handset type LBB 3555.
3. 15-pole Sub-D type connector for connection to the DCN trunk-line.
4. ISA-bus (8-bit) connector
5. 2 m (6.5 ft.) long trunk-line input cable, terminated at one end with a 6-pole moulded circular
connector (male) and at the other with a 15-pole D-sub plug (female) matching the 15-pole
socket on the PCB (3) .
