facing down.
To connect the RS-485 cable to the Gateway, start by opening the cover of the Gateway. Keep the cover in a clean, safe
place to prevent dirt from getting on the seal.
Insert the RS-485 cable through the left gland on the bottom of the Gateway. Tighten the cable wires into the bulkhead
connector using a small screwdriver. Remove the connector from the circuit board for easier handling
Make sure that the wire connected to each terminal in the Gateway matches the connections in the Management Unit.
If the system has multiple gateways, use the second connection for the outbound cable to the second gateway. Remove
the termination resistor (the small electrical component) from the right four-pin connector in order to wire the outbound
RS-485 cable to the next Gateway. Only the final Gateway in the series connection should have a termination resistor.
When finished, replace the cover of the Gateway. Hand-tighten screws only.
2.2 Gateway Location
The ideal location for the Gateway is underneath one of the central panels in the array so that the distance from any
corner panel to the Gateway is the same. The Gateway comes pre-mounted on a bracket which can be attached to a
module frame with the included clips. When attaching to a module place in the upper left hand corner with antenna
pointing downward. Its exact location can be optimized when you verify the Gateway signal.
