Universal Communication
Gateway Reference Manual
The Universal Communication Gateway (UCG) is an external, high performance Building
Automation multi-protocol gateway that is preconfigured to automatically communicate
between Bryan Steam’s products (hereafter called “device”) connected to the UCG and
automatically configures them for BACnet®MS/TP, BACnet IP, Metasys®N2 by JCI,
Modbus TCP/IP or LonWorks®. All Honeywell SOLA, Siemens RWF 40/55, Siemens LMV,
Honeywell RM7800 Series and the Precision Digital Trident PD765 boiler configurations
and Node-ID’s are selected through the UCG Web GUI Configurator for fast and easy
installation. A mix of multiple devices can be used on a single UCG. It is not necessary to
download any configuration files to support the required applications. The UCG is pre-
loaded with tested Profiles/Configurations for the supported devices. This document
provides the necessary information to facilitate installation of the UCG on BACnet
MS/TP, BACnet/IP, Metasys N2 and LonWorks network.
The UCG is provided as a 10” x 12” x 6” NEMA Type 1 control panel that must be
mounted and supplied with 120 VAC. Additional specifications can be found in Section
7.
Important
1. If your boiler is equipped with a Bryan Boilers Printed Circuit Board
(WD-857), devices should be pre-wired. See section 3.1.8.
2. Each boiler device Modbus settings must be configured to
communicate to the UCG.

1HOW TO USE THIS
MANUAL
This manual may be used in its entirety or
as a reference. You may need to reference
your device’s manual for information not
covered in this UCG manual. The three
main sections are as follows:
Section 2: Mounting UCG – This section
is for mounting the UCG control panel,
connecting power and building
management connections.
Section 3: Connect and Setup for Boiler
Devices to the UCG – This section is for the
connections and set-up of each device for
the Modbus communication to the UCG.
Section 4: Setup for UCG – The section is
for the set-up of the UCG to communicate
to the devices (Modbus) and to your
building management system.
All other sections are supportive of the
sections above.
2MOUNTING UCG
2.1 MOUNTING
Mount the UCG in a suitable location that is
easy to access. Verify that the UCG power
switch is in the “off” position. Connect J1-
1(L1), J1-2(L2) and J1-3(G) of the UCG-PCB
WD-856 to a 120VAC power source.

3.1.8 BOILERS EQUIPPED WITH
BRYAN STEAM PRINTED
CIRCUIT BOARD (WD-857)
Boilers equipped with a Bryan Steam
Communication PCB (WD-857) can be
interconnected using the two RJ45 jacks
installed on the board. Standard CAT5 cable
wired as T-568A or T-568B straight through
can be used for the interconnection
between the devices that are factory wired
to the Bryan Steam Communication PCB
(WD-857) and P1 of the UCG-PCB WD-856
inside the UCG.
The Bryan Steam Communication PCB does
not need to be wired in sequential order as
this will be handled in the device
addressing.
Figure 14 - Bryan Steam Communication PCB (WD-857) and Multi
Boiler Connection
3.1.8.1 END OF LINE TERMINATION
SWITCH
Long RS-485 cabling runs of 20ft. or more
should be properly terminated at each end.
If needed a 120Ω terminating resistor
should be between J3-7 and J3-8 of the
UCG-PCB WD-857 on each end of the trunk
(See Figure 12, Boiler #3). If the UCG is
placed at one of the ends of the trunk, the
blue RS-485 End-of-Line Terminating switch
inside the UCG will need to be moved to the
ON position. Remove the cover of the
ProtoNode and move the Modbus RS-485
EOL Switch to the ON position.

3.2 DEVICE MODBUS RTU COM
SETTINGS
All devices connected to the UCG MUST
HAVE the same Baud Rate, Data Bits, Stop
Bits, and Parity. Refer to the UCG
configuration sheet or the multi-device
wiring drawing (generally shipped with
boiler) for the appropriate address and
baud rate settings for each device.
Section 7.1 defines the installed default
serial port settings for each device.
If your boiler device has a Bryan Steam
ModBus Address label (Form 2445)
attached to the boiler device, it has been
set up and will have the address written on
the label.
Set Modbus Node-ID for each of the devices
attached to UCG. The Modbus Node-IDs
need to be uniquely assigned between 1
and 255. Use the table in section 8to
record boilers, devices and Node-ID.
•The Modbus Node-ID’s assigned are
used for designating the Device
Instance for BACnet/IP and BACnet
MS/TP.
•The Metasys N2 and Modbus TCP/IP
field protocol Node-IDs are
automatically set to be the same
value as the Node-ID of the Modbus
RTU device.
Select the device below:
Honeywell SOLA see section 3.2.1
Siemens RWF40 see section 3.2.2
Siemens RWF55 see section 3.2.3
Siemens LMV2…/LMV3… see section

3.2.1 HONEYWELL SOLA
3.2.1.1 SET SOLA ADDRESS
If you are prompted for a Passcode use
Bryan.
Each individual SOLA will now need its own
unique address. Follow these steps to setup
the addressing for each SOLA:
•Select the SOLA controller
•Select Configure
•System Identification and Address
•Scroll to the bottom
•Change MB1 and MB2 to the same
Modbus address.
•Press the Home button
•Select Setup
•Select Display Diagnostics
•Select Display Reset
•Repeat for each boiler. Numbering
them accordingly.

3.2.2 SIEMENS RWF40
Each RWF40 device will need to be setup
with its own unique address. The decimal
place, unit, and Baud rate will need to be
setup the same on all devices.
Modbus settings
Press and hold for 3
seconds, and then release to
access the parameter level.
From the parameter level, advance to the
configuration level by pressing again,
holding for 3 seconds, and release.
Press and release it, to
advance to C112, press again
and release it, to advance to C113.
Changing Values
Select the desired digit that needs adjusted
by pressing once and releasing it.
(Each time is pressed and released it
will cycle, thru each digit, right-to-left and
back again)
To change the value of the flashing digit,
press and release it.
(Pressing and releasing will cycle up
thru the allowable values, and back again.)
Once the desired value is displayed and
flashing, accept it by pressing once
and release it. If no keys are pressed for 30
seconds, at any time, the controller will
automatically return to the basic display.
