General Description

BACnet MS/TP Communications Module

A BACnet MS/TP Communication Module can be plugged
into the MCB as shown in Figure 4 on page 4.
The BACnet MS/TP Communication Module is designed to be
an add-on module to the MCB for networking to Building
Automation and Control Network (BACnet) systems. It is a
plug-in module that can be attached to the MCB via a 12-pin
header, and includes four locking stand-offs to securely attach
it to the board. It allows the MCB to interoperate with systems
that use the BACnet Master Slave/Token Passing (MS/TP)
protocol with a conformance level of 3. The MicroTech II
Applied Rooftop Unit Controller meets the requirements of
ANSI/AHSRAE 135-2001 standard for BACnet systems.
For a detailed description and troubleshooting information
regarding this communications module, refer to installation
and maintenance bulletin IM 704, MicroTech II Applied
Rooftop Unit Controller and Self-Contained Unit Controller
BACnet Communication Module—BACnet / MS/TP. For details
regarding BACnet protocol data, refer to engineering data
document, ED 15060, MicroTech II Applied Rooftop Unit
Controller Protocol Information.
A unit equipped with the optional BACnet MS/TP
Communication Module is connected to a BACnet network
through terminals 128 (+) and 129 (-) on terminal block TB2
in the main control panel. These terminals are factory wired to
the BACnet MS/TP module when the module is factory
installed. When the module is field installed, the add on
communication module kit includes a wiring harness to be
installed between terminals 128 and 129 and the BACnet MS/
TP module. This connection is shown schematically in
Figure 5 on page 7.

L W ® Communication Modules
ON ORKS
A L W Communication Module can be plugged into
ON ORKS
the MCB as shown in Figure 4 on page 4. This module
provides L W network communication capability to the
ON ORKS
MCB. It is a plug-in module that can be attached to the MCB
via a 12-pin header, and includes 4 locking stand-offs to
securely attach it to the board.
For a detailed description and troubleshooting information
regarding this communications module, refer to installation
and maintenance bulletin IM 702, MicroTech II Applied
Rooftop Controller and Self-Contained Unit Controller
L W Communication Modules. For details regarding
ON ORKS
L M ® protocol data for these modules, refer to
ON ARK
engineering data document, ED 15060, MicroTech II Applied
Rooftop Unit Controller Protocol Information.
There are two versions of this module available. One is the
L M Space Comfort Controller (SCC) module and the
ON ARK
other is the L M Discharge Air Control (DAC) module.
ON ARK
Space Comfort Control (SCC) Module.
Controller (SCC) module supports the LonMark Space
Comfort Controller (SCC) functional number 8500.
Discharge Air Control (DAC) Module.
Controller (DAC) Communication module supports the
L M Discharge Air Controller (DAC) functional number
ON ARK
8610.
A unit equipped with an optional L
module can be connected to a L
terminals 128 (A), 129 (B) on terminal block TB2 in the main
control panel. These terminals are factory wired to the module
when the module is factory installed. When the module is field
installed, the add-on communication module kit includes a
wiring harness to be installed between terminals 128 and 129
and the module. This connection is shown schematically in
Figure 5 on page 7.
