Address Jumpers.

Locations and settings of address jumpers are shown on

the computer-generated wiring diagram provided with the system hardware. Figure 4-6
shows a portion of a typical computer-generated wiring diagram. Address jumper
connectors are A0, A1 and A2. Open jumper connectors are shown in grey on the wiring
diagram. Connectors shown in black require a jumper to be installed. Address jumpers
must be set properly on all LEMs and REMs in order for the system to operate correctly.

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 left 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.
