8 Ethernet/Optic Fibre/RS485 Combined Network
The example diagram below illustrates the required hardware and wiring required for a
network that combines ethernet, optic fibre and RS485 star topology. The NEMTEK
Power Pack may be used to provide a 12V supply with battery backup FG7 and 8-way
Relay Board and optic fibre converters. Note that the ethernet, RS485 5-core and 10-way
ribbon cables should have a maximum length of 100m, 1000m and 1m respectively.
It is recommended that the 5-core cables for RS485 communication are shielded and
that the shields are grounded only at one end of the cable to prevent ground loops.
To set up the network, follow these steps:
1. For the connection setup between the PC and FG7 module, refer to the FG7 installer
manual. The PC to FG7 link is optional to run the NEMTEK Fenceprobe software.
2. For the setup of the ethernet part of the network including the FG7, Nemlink
and Ethernet/Fibre converters, refer to section 5 (NEMTEK Ethernet Module
Setup) and 6.2 (Ethernet/Optic Fibre Network Setup) of this document.
