PROTONODE-RER-1.5K /
PROTONODE-RER-10K
Multi-Protocol Device Server Initial Setup Guide
The nVent RAYCHEM ProtoNode-RER multi-protocol gateway
is used to connect nVent RAYCHEM C910-485, TraceTek SIM,
and ACS-30 Controllers to Building Management Systems (BMS)
using BACnet or Metasys N2 protocol.
The ProtoNode-RER is preprogrammed with the RAYCHEM
Modbus registries for simple integration into your BMS. The nVent
RAYCHEM ProtoNode-RER-1.5K is configured to communicate
with up to 6 C910-485 controllers or an nVent RAYCHEM ACS-30
system up to 25 circuits. The nVent RAYCHEM ProtoNode-RER-
10K is configured to communicate with an ACS-30 system up to
170 circuits.

ADDITIONAL INFORMATION
The ProtoNode-RER gateways are highly flexible and
accommodate the most commonly used protocol. They come
pre-programmed with the Modbus mapping of the C910 and
ACS-30 controllers.
The initial set up of these controllers is outlined on:
Page 2 for the ProtoNode-RER (BACnet and Metasys N2)
The set-up involves 4 steps:
1. Configure the DIP switches for address, baud rate, protocol
and RAYCHEM controller (Figure A)
2. Connect RS-485 to RAYCHEM controller (Figure B)
3. Connect power supply to ProtoNode (Figure B)
4. Connect to the Field or BMS system after the completing
steps 1-3 (Figure C)
Once the gateway is connected and configured the RAYCHEM
Modbus registries will be visible to the system integrator through
the field BMS.
Communication set-up requirements for C910 and
ACS-30 controllers:
Protocol: Modbus-RTU (default for ACS-30)
Baud rate: Auto or 9600
Parity: None
Modbus Address: 1
