5-2.2.6 End-of-Line Jumpers
The End-of-Line (EOL) jumpers are required for MAXIM Series controllers that are installed on a
subsystem network. 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 a MAXIM controller installed on a
subsystem network, you must place the EOL jumper on that controller.
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 last controller in the network.
