Connectivity
The integral RS485 Serial Port (CN2 on the DRV80 PCB) can be used to connect to either BrainScan® or
directly to Building Automation Systems (BAS) which operates on a Modbus RTU protocol.
See Options screen on page 38 for details on how to switch DRV80 for either BrainScan® or Modbus.
BrainScan® (not available in Europe)
BrainScan® is an optionally selected control module from Armstrong which enables an interface with Building
Automation Systems (BAS) which utilize Modbus, Bacnet™ or LonWorks™ protocols via the use of specic
ProtoCessor cards.
BrainScan® also has an ethernet port and operates as a web server for remote network access.
BrainScan® includes remote hot water supply, cold / recirculation water supply, blended water outlet temperature
outputs and is supplied with a system graphic, memory card for data storage and web based software.
BrainScan® includes terminals for additional installer supplied RTDs, pressure transducers and pulse type
ow meters and this data can be forwarded via the BrainScan® interface.
A separate BrainScan® specic Installation, Operation and Maintenance (IOM) Guide is available upon
request. Please consult factory or visit:

Modbus
Modbus – DRV80 can be congured to communicate directly with BAS which utilize Modbus RTU.
When congured for Modbus the DRV80 becomes a Remote Terminal Unit (RTU).
When connected directly to a BAS using Modbus RTU, the DRV80 will be assigned a unique network address
which is programmed via the integral DB9 external port.

request. Please consult factory or visit:
