STULZ CyberRow DX Series Installation, Operation & Maintenance Manual
4.7 BMS Communication
When BMS communication is utilized, the controller must
be equipped with an optional expansion card designed
for one of a variety of serial communication protocols
available (see Section 4.1.4
) . A communication port on the
expansion card allows the controller to be fi eld connected
to a central Building Management System (BMS) for
monitoring and control of data points.
A RS-485 serial port is available for Modbus or BACnet
MS/TP protocols and a 10BaseT port is available for TCP/
IP based protocols such as BACnet over IP, BACnet over
Ethernet, SNMP or HTTP.

If multiple A/C units are grouped together, each controller
added to the group must be confi gured with a CPU address
for BMS communication.
For complete details on utilizing BMS control, contact
STULZ Product Support (see Section 6.0).
4.7.1 Direct BMS Control
The controller may be confi gured to accept proportional
analog signals that mimics a sensor. The controller will act
on that signal whether it comes from a real sensor or a
BMS analog output.
Refer to Section 4.9 for the
E²
controller's BMS
parameters.
4.7.2 BMS Communication
SERVICE
Alarms
BMS Comm
Run Hours
The Service>BMS Comm menu is used to set up the
parameters to allow a BMS (BAS) interface for monitoring
controller operation for the serial-based networks such as
BACnet MS/TP. Units using the BACnet over IP, BACnet
over Ethernet, or HTTP protocols do not need to change
anything in this menu loop.
BMS Communications
Address: 1
Baud Rate: 19200
Protocol: BACnet
BMS keep alive: 1
The BMS address and baud rate have meaning only on
RS-485 networks and with the serial protocols of Modem,
Modbus RTU, Commission, and Carel. The baud rate is
fi xed for BACnet. Systems utilizing a 10BaseT interface
should use the defaults of address 1, baud rate 19200,
and protocol BACnet.
Certain Integer and Digital variables that start with
BMS (see page 4-49) require that the BMS "keep alive"
parameter changes between 1 and 2 within a 10 minute
span. The general procedure is to set up variables like the
BMS low fan speed and then write a 1 to the BMS "keep
alive" address.
