Accessing Smart Equipment Using
the MAP Gateway
When the MAP Gateway is physically connected to an
MS/TP network, users can have access to Smart
Equipment devices. The MAP Gateway can connect
through the SA bus or through the FC bus.
Through the Sensor Actuator (SA) Bus
If the MAP Gateway is connected through the SA bus
(for example, point A on Figure 12), it can access the SE
device and all SE devices on that device's FC bus when
the FcBusMode is set to Wired Field Bus (BACnet
MSTP) in the UCB display menu of the units connected
to the FC bus network. You can connect the MAP
Gateway through the local SA Bus jack on the equipment
control board. Or, if a Net Sensor is installed, you can
connect the MAP Gateway directly to the RJ-12 jack on
the Net Sensor.
Through the Field Controller (FC) Bus
If the MAP Gateway is connected through the FC bus
(point B in the example), it has access to SE devices on
that FC bus only when the FC bus protocol is BACnet
MSTP. For individual units connected to the FC bus
network, the FcBusMode is set to Wired Field Bus
(BACnet MSTP) in the UCB display menu. The MAP
Gateway can be connected to the FC bus through the
RJ-12 connector on the Field Bus card of the smart
equipment. Or, using an RJ-12 to Terminal Block Adapter
(MP-STAFBA-0), you can connect the MAP Gateway
directly to the field bus.
To interact with a device or product on the network (to
view devices, setpoints, or view alarms), users select the
device using a web-enabled device that is connected to
the MAP Gateway Wi-Fi network. To use the network,
users must have a web-enabled device that uses a
supported Internet browser. For information on connecting
to the network, see Connecting to the MAP Gateway
Wi-Fi Network.

Important: If you are going to use the MAP Gateway
on Ethernet, you must plug it into external
power before you attach the field bus
adapter.
1. Connect the FC/SA port of the MAP Gateway to the
sensor bus or field bus port of the equipment
controller using the supplied RJ-12 cable (portable
model) or field bus adapter (stationary model)(Figure
13). The MAP Gateway's LEDs flash, indicating that
the device is initializing. When the Fault LED turns
