A-4.1.2. Linking Networks in Different Locations. When linking networks in

different buildings, or when linking modules supplied from different switchboards, isolation

must be provided to eliminate earth loops. Use a GENII RPTR Repeater Module to isolate

the networks (Figure A-3). Note that the cable going to the more remote zone is always

connected to Port 2 of the Repeater Module.

Figure A-3. Linking Networks in Different Locations.

A-4.1.3. Multi-Network Arrangement. Figure A-4 shows a multi-network

arrangement consisting, effectively, of four separate networks. Each is wired in a bus

topology and each could be up to 1000 metres long. The networks are linked by the

electronics in the Repeater Modules. The GENII MPI Modem and Printer Interface does

not need to be an isolated version but it should be noted that the Comms cable connecting

Ports 2 of the Repeater Module will be earthed through the MPI via the PC and the printer.

The correct port of the Repeater Modules must be used to maintain the integrity of isolation

between sections.
