Application
The M4-XPM series expansion I/O modules can serve
in one of two capacities depending on where they are
installed in the Metasys system. When installed on the
Sensor/Actuator (SA) Bus of an equipment controller, an
XPM expands the input and output interfaces that can be
used with that equipment controller. When installed on
the Field Controller (FC) Bus of a Metasys network engine,
an XPM can be used as I/O point multiplexors to support
monitoring and control from a Metasys network engine.
The point multiplexor can also be useful for sharing points
between other equipment controllers on the FC Bus using
peer-to-peer connectivity. XPMs operate on an RS-485
BACnet MS/TP Bus and are BACnet Testing Laboratory
(BTL) listed and certified to the BACnet Smart Actuator (B-
SA) profile.
Communications Protocols
The XPM expansion modules can communicate using
BACnet MS/TP or wireless using a ZFR/ZFR Pro Wireless
Field Bus Router (on the FC Bus only). By default, the XPM
expansion modules communicate using the BACnet MS/
TP protocol. The BACnet protocol is a standard for ANSI,
ASHRAE, and the International Standards Organization
(ISO) for building controls. To configure these expansion
modules in a wireless application installation, see
Configuring wireless
communications.
Note: Using Controller Configuration Tool (CCT)
10.1 and later, Metasys Equipment Controllers
can be configured to communicate using either
the BACnet MS/TP or the N2 field bus networking
protocol. The operation of an XPM on the SA Bus
of an equipment controller is not affected by the
selection of the BACnet MS/TP or the N2 protocol in
the host controller.
North American Emissions Compliance
United States
This equipment has been tested and found to comply
with the limits for a Class A digital device pursuant to
Part 15 of the FCC Rules. These limits are designed
to provide reasonable protection against harmful
interference when this equipment is operated in a
commercial environment. This equipment generates,
uses, and can radiate radio frequency energy and, if not
installed and used in accordance with the instruction
manual, may cause harmful interference to radio
communications. Operation of this equipment in a
residential area may cause harmful interference, in which
case the users will be required to correct the interference
at their own expense.

Installation
Observe the following guidelines when installing an XPM
expansion module:
• To minimize vibration and shock damage transport the
expansion module in the original container.
• Verify that all parts shipped with the expansion module.
• Do not drop the expansion module or subject it to
physical shock.
Parts included
