Genesis II Installation Instructions

4-1.4.2 End of Cable Jumpers

Although the locations of End-of-Cable jumpers are not shown on the computer-generated wiring

diagram, they are easily located close to the unit’s RS485 Comms connector. Figure 4-7 shows the

location of the End-of-Cable jumper for a GENII AI REM unit. Jumpers for other units are similarly

placed. The rule for installing an End-of-Cable jumper is:

• If only one cable is connected into an RS485 Comms connector, a jumper must be installed in that

unit.

• If two cables are connected to the same RS485 Comms connector, the jumper plug must be le

open.

All units along the RS485 Comms network should be carefully checked to ensure that jumpers are

installed only in the last unit in the network.
