Rail Screws
Note: The screw holes on the MAP Gateway can
accommodate M3.5 and #6 screws.
3. Drill holes in the wall based on the locations marked
in the preceding step, and insert wall anchors for each
hole (if necessary).
4. Hold the bracket in place, insert the screws through
the mounting clips and into the screw holes, and then
carefully tighten all screws.
Important: Do not overtighten the mounting screws.
Overtightening the screws may damage
the mounting clips or bracket.
5. Place the MAP Gateway unit in the bracket and
secure the bracket with the locking screw.
Wiring
Wiring Consideration and Guidelines
Observe the following guidelines when wiring the MAP
Gateway:
• Do not allow the MAP Gateway to hang from a cable
connection.
• Provide some slack in the cable between the MAP
Gateway and the controller or other device to which
you are connecting.
SA/FC Port
The MAP Gateway has one RS-485 FC/SA bus port that
connects through a supplied 6-pin modular jack and cable
assembly. For data transmission and voltage
specifications, see the Technical Specifications section.
Do not plug the SA/FC connector into a standard phone
jack.
See the Features section for the location of the
communications terminal on the MAP Gateway.

Field Bus Communications Connections
To connect the MAP Gateway to the SA/FC field bus for
communication, connect one end of the RJ-12 cable to
the MAP Gateway and the other end of the cable to a
controller or network sensor.
Note: The MAP Gateway has a dedicated MS/TP bus
address of 03. The number of MAP Gateway units
that can be connected simultaneously to one
MS/TP bus depends on the number of FC and SA
ports available and connected to the bus. The
MS/TP bus can accommodate one MAP Gateway
on the FC bus and one MAP Gateway for each
SA bus connected to the trunk.
Performance of the MAP Gateway varies based
on the number of SA bus connections and amount
of traffic.
