5-1.5 Check EOL Jumpers
The End-of-Line (EOL) jumpers are required for RS-485 connected devices. There are certain rules
that must be followed for proper installation of End-of-Line jumpers.
If only one cable is connected into an RS485 Comms connector on an Omni U10 REM, you must place
the EOL jumper on that device.
If two cables are connected to the same RS485 Comms connector, the jumper should NOT be
installed.
All controllers along the RS485 Comms on a sub system network should be carefully checked to verify
that the EOL jumpers are installed only on the first and last device in the network.

The IG01 is connected to two comms channels,

Using two ports allows for data sharing.
