Setup Manual
BACnet Protocol Gateway for TempTrac® and
XR10CX Water Heater Control
When a BAS interface with Temptrac or the XR10CX requires a protocol other than the standard
Modbus RTU for Temptrac and XR10CX, PVI Industries offers a premapped gateway from FieldServer
Technologies. The ProtoCessor ProtoNode RER currently supports BACnet IP or MSTP. Consult factory
for other protocols.
This manual is meant to be a general overview of the application of this gateway, for additional
configured with the following specifics: IP address, serial address, baud rate and one of three register
profiles.

POWERING UP THE PROTOCESSOR/PROTONODE
Power LED comes on and remains solid
LA starts flashing about once per second. This tells us that PIC (Peripheral Interface Controller)
number 1 in the ProtoCessor has powered up successfully.
LB starts flashing about once per second. This tells us that PIC number 2 in the ProtoCessor has
powered up successfully.
GP105 will go on solid within 45 – 60 seconds after power up, signifying normal operation.
ProtoCessor will be able to come up in RUINET shortly after this LED comes on. During the first
45‐60 seconds the LED should be dark.
Upon successful operation of GP105 the ProtoCessor will go through diagnostics of the field port
communications.
The FFP‐ETH module is operational after this point.
RX Field Port LED: On normal operation, the RX LED will flash when a message is received on the
field port of the ProtoCessor.
TX Field Port LED: On normal operation, the TX LED will flash when a message is sent on the field
port of the ProtoCessor.

CONNECTION TO PROTOCESSOR USING UTILITIES
Make sure that the FST Utilities is downloaded on the computer.
Connect an Ethernet cross‐over cable between the PC and ProtoCessor or connect the
ProtoCessor and the PC to the Hub/switch using a straight cat5 cable.
The Default IP Address of the ProtoCessor is 192.168.1.24, Subnet Mask is 255.255.255.0.
If the PC and the ProtoCessor are on different IP Networks, assign a Static IP Address to the PC
on the 192.168.1.0 network.
Double click on the “RUIPING” Utility. If the IP Address of the ProtoCessor module appears on
the screen, the ProtoCessor is running.

Double click on the debugging utility, “RUINET4” (Remote User Interface). The following screen
will appear:
See the “ProtoCessor Mapping” document to ensure that the device is set up correctly with
respect to Baud rate, Node Address, and Points which are configured in the device.
Select “O” for Connect Overview to see the number of messages on each protocol. If the
ProtoCessor is communicating correctly with the device then the display will show Tx and Rx
messages without any errors.
If there are errors on the ProtoCessor socket communications, then the points list in the CSV file
will require editing until there are no errors. Each time the points are edited, the CSV will need
to be re‐downloaded using Ruinet.
When communication between the device and the ProtoCessor is established the Field Side of
the ProtoCessor may be connected to the appropriate device/software. Ensure that the Field
Side parameters on the device/software are set up as per the “ProtoCessor Mapping”
document.
Read and Write data from each side and make sure the ProtoCessor works as expected.

TROUBLESHOOTING TIPS
If PWR LED does not come on and LA and LB don’t flash, call or email ProtoCessor support
If PWR LED does not come on but the LA and LB flash, then the PWR LED is broken.
If LA and LB don’t start to flash there could be a problem with the ProtoCessor and you need to
contact [email protected].
If GP105 never comes on then you need to contact ProtoCessor support.
If TX and or RX don’t flash, it may represent a problem with the field wiring or Configuration
problems in the ProtoCessor on field side or incorrect polling parameters (such as COMM
properties like baud, parity, and etc).
The Gateway is unable to find one or more controls in the RS485 network. The individual
controls may not be programmed with the correct and unique node address. See the respective
control manual for details.
The Gateway has no communication with the controls in the RS485 network. Check the RS485
wiring for correct wiring method. See page 2 of this manual for details.
