Wiring the SIM Gateway
To wire the SIM gateway, perform the following steps:
Step Action
1 At the control unit, make sure the Power switch is in the "OFF" position.
2 Run the buses as required and make sure to appropriately tag them. Limit each RS-485
bus to a single wire run.
Note:
It is important to appropriately tag the cables so they can readily be identified.
This is especially important if troubleshooting becomes necessary at some future date.
3 Run the cable through one of the three 1/2" knockouts of the housing unit. Cut the cable
and remove enough sheathing and insulation from each wire to allow fastening under
the pressure plates of TB1 and TB2.
4
Measure the resistance between the black and red conductors (the (+) lead of the meter
to the red conductor and the (-) lead to the black conductor). A reading less than 12 ohms
indicates a short on the power conductors or an excess of protection points. Make the
necessary corrections before proceeding.
5 Connect the RS-485 cable to TB1 of the gateway
.
Identify terminal wires so that the
proper wires can be connected to each terminal. See
Figure 5-6.
6 Connect the RS-485 bus cable to the control unit (see table below).

Addressing the SIM Gateway
To address the SIM gateway, perform the following steps:
Step Action
1
Set the RS-485 address jumpers to Communication Group 3 and to a Unit Number from
0 to 7 (see
Figure 5-6
).
2 Set jumper E1 to the appropriate setting:
• Remove jumper if gateway is
NOT
located at the end of the RS-485 bus.
• Leave jumper intact if gateway
IS
located at the end if the RS-485 bus.
3
Mark the SIM Gateway address on the Housing Unit cover using stick-on labels.
If system power calculations were required, make sure that the Gateway will be receiving at least 12.1 volts
(or 8.4V at end of standby time) and that the length of the Gateway trunk is within the maximum
permissible distance calculated in
Power Requirements
section.
