ProtoNode Gateway Manual 

BACnet and LONworks Protocol Gateway for OnTrac ® , 

TempTrac ® and XR Boiler Control 

When a BAS interface with OnTrac, TempTrac or the XR requires a protocol other than the standard 

Modbus TCP/IP for OnTrac or Modbus RTU for TempTrac and XR, Riverside Hydronics offers a 

premapped gateway from FieldServer Technologies. The ProtoNode currently supports BACnet MSTP, 

BACnet IP, and Lonworks. Consult factory for other protocols. 

This manual is meant to be a general overview of the application of this gateway, for additional

CONNECTION TO PROTONODE USING UTILITIES 

The default ProtoNode IP address may not fit within the existing network address pool. The following 

instructions describe the utilities used for changing the ProtoNode IP address. If interfacing with an 

OnTrac, you may need to edit the profile in the ProtoNode to include the OnTrac’s IP address, this is 

explained in detail in the supplement document 34-525C-1 and 34-525C-2. The OnTrac IP setting 

procedure is explained in the OnTrac manual 34-152. Utilities for configuring the ProtoNode are available 

from Fieldserver’s website. Make sure that the Fieldserver Utilities are downloaded and installed on your 

computer. 

( http://www.fieldserver.com/docs/downloads/Install.zip ) 

Connect an Ethernet cross-over cable between the PC and ProtoCessor or connect the ProtoCessor and 

the PC to a Hub/switch using straight through patch cables. 

The Default IP Address of the ProtoNode IP address is 192.168.1.24, Subnet Mask is 255.255.255.0. 

If the PC and the ProtoNode are on different IP Networks, assign a Static IP Address to the PC on the 

same network. Example, with the default settings of the gateway on 192.168.1.24, the network is 

192.168.1.XXX then 192.168.1.8 will be a valid IP address for your computer. Instructions on how to 

change the IP address of your computer is beyond the scope of this manual. 

Launch: FieldServer Utilities > Ping Utility ("C:\FieldServer Technologies\FieldServer Utilities\Bin\ruiping.exe"). If the IP 

Address of the ProtoNode module appears on the screen, the ProtoNode is running. 

You can exit this program by hitting ESC key. 

The next program “Remote User Interface” is used to change the IP address of the gateway, view 

communication between the devices, and update the configuration files of the gateway. 




Launch: FieldServer Utilities > Remote User Interface ("C:\FieldServer Technologies\FieldServer Utilities\Bin\ruinet.exe"). 

The following screen will appear if it can connect to the gateway: 

CHANGE IP ADDRESS: Option “I” will allow changing the IP address of the Gateway. 

VIEW COMMUNICATION: Select “O” from the main menu screen for Connect Overview to see the 

number of messages on each protocol. If the ProtoNode gateway is communicating correctly with the 

device then the display will show Tx and Rx messages without any errors. Below SMT is the 

communication of your computer with the gateway, and can be disregarded. Modbus RTU is 

communication directly to a TempTrac, not used in this example. Modbus/TCP is the communication to 

the OnTrac boiler group control. BACnet_MSTP is the BAS talking to the gateway. In this example, the 

BAS is not using the BACnet_IP interface. 




BACK UP GATEWAY FILES: It is highly recommended to back up the configuration files before 

performing any update or editing of the configuration. In order to back up the configuration files stored on 

the gateway, perform the following steps. 

 

 

 

 

 

 

 

 

Clear or move any files from the Field Server Configuration files folder. There is a short cut to this 

in the program group: FieldServer Utilities > Config ("C:\FieldServer Technologies\FieldServer 

Utilities\Config”). 

From the main menu hit U (Upload Configuration file from Field Server). 

Hit U to upload the default CONFIG.CSV to your computer. 

Once that is complete, you will need to enable the “Other Filenames” option by hitting the “O” in 

the Upload menu. 

Once this is done, perform the following for each file PROF1.CSV, PROF2.CSV, PROF3.CSV 

From the Upload menu, Hit ”R” and then type the file name PROF1.CSV and hit Enter. 

Hit “L” and type the same name again and hit Enter. 

Hit “U” to upload the file to your computer. It will be located in the previously mentioned CONFIG 

folder. 

Once this has been done for all the files, back up the files in your CONFIG folder in case you 

need to revert back to the original files. 

UPDATE CONFIGURATION FILES ON GATEWAY: Once the files have been backed up and save to a 

safe place, you can then place the new files, or edited old file in the CONFIG folder for transfer to the 

gateway. 

 

 

 

 

 

 

 

Clear any old program from the CONFIG folder, and place the files that are to be transferred to 

the gateway in this folder. 

From the main menu, hit “D” (Download Configuration file to Field Server). 

From this menu, if you are uploading the CONFIG.CSV file, simply hit the “D” key again. 

To transfer any of the other files, you will need to enable the “Other Filenames” option by hitting 

the “O” in the Download Menu. 

To transfer the PROF1.CSV file from the CONFIG directory on your laptop to the gateway: 

From the Upload menu, hit “L” and type PROF1.CSV and hit Enter. 

Hit “R” and type the same name again and hit Enter. 

Hit “D” to Download to the Gateway. 

Once all files that are required have been transferred to the gateway, get back to the main menu by 

hitting ESC, from the main menu, hit “!” to reboot the gateway (or remove power from gateway). It will 

take a couple of minutes to reboot. Once it has finished, from the main menu, hit “E” to see if there are 

any errors after loading the new configuration files. 

The default IP for the OnTrac is 192.168.1.100 and the Default for the gateway is 192.168.1.24. If the 

building IP network require different IP addresses, it is necessary to change both the Protonode 

PROF1.CSV client configuration for the OnTrac and the OnTrac IP. This topic is covered in detail in the 

34-525C-1 BACnet document, and the 34-525C-2 LONworks Document. See the OnTrac manual 

Document 34-152 for instructions on changing the OnTrac IP address. 



ASSIGNING TEMPTRAC ADDRESSES 

In order to set up the network communication system, each water heater’s TempTrac control must be 

assigned an address. In installations with multiple TempTrac controls, a different address must be 

assigned to each TempTrac. 

The following instructions are specific to the TempTrac®. If your water heater uses a different control 

refer to the programming instruction for that control to set the address. 

1. On the face of the TempTrac control, enter the programming mode by pressing and 

holding the “set” and “down arrow” keys together for 3 seconds. 

2. The upper LED readout should read “St1” with a numeral (the St1 setting) appearing in the lower LED 

readout. 

IMPORTANT: If the lower readout indicates “Pof”, the TempTrac control is locked for programming. To 

unlock the control, press and hold the “up arrow” and “down arrow” keys together until the lower LED 

readout indicates “Pon”. The TempTrac control is now unlocked. Repeat step 1 to proceed with 

assigning the TempTrac address. 

3. Press the “down arrow” key. 

4. “Pr2” will appear in the upper LED readout and “Pas” will appear in the lower LED readout. 

Press the “set” key to begin entering the password to allow programming. 

5. In the lower LED, the value “0 - -” (zero, dash, dash) with a flashing zero will be displayed. 

6. The programming password is “321”. Use up arrow key to input each digit in the security code. 

Confirm each digit by pressing “set” key. After each confirmation, the next digit will begin to flash. 

7. After entering the third digit and pressing “set”, “Pr2” will appear in the upper 

LED readout. Press the “down arrow” key three times and the parameter 

“Adr” will appear in the upper LED readout. The lower LED readout will 

indicate the default address “1”. (See image to the right.) 

8. Press the “set” key once and the number will begin to blink. Use the “up 

arrow” key to set the address from (1 to 247). When the proper address is 

indicated in the lower LED, press “set” key. 

Adr 

1 

9. The address is programmed. After approximately 30 seconds, the LED 

readouts will return to the default temperature reading mode.
