3-2 Sub System Network
The Sub System Network is a sub network that connects to the Innotech primary network via a
gateway. The Sub System Gateway IG01 is a data concentrator for the Sub System Network.
The Sub System Network is a two wire network that communicates at 115K. It is a requirement that
the EOL jumpers are fitted correctly and that each device is earthed correctly.
No devices on the Sub System Network have an earth terminal. All devices must have the 0V earthed.
There are currently five devices that exist on the Sub System Network. See the table below:
