COMMUNICATION WIRING AND SETUP
All RCT1000 transmitters include EIA-485 and USB programming ports .
OTEE:
N
An RS485 Terminator resistor is provided for when end-of-line termination is required . The RCTX and RCTX with
Display transmitters are shipped from factory with the shunt jumper in ”Not Terminated” position .
EIA-485 Port
The EIA-485 port is used for network connections and supports two protocol options: Modbus RTU and BMI Massmeter .
USB Programming Port
The USB programming port is used for connecting a computer with RCT Console configuration and diagnostic software to the
RCT transmitter . The USB programming port supports two protocol options: Modbus RTU and BMI Massmeter . RCT Console
defaults to BMI Massmeter but can be changed to Modbus RTU if required . Both ports remain active while RCT Console is
communicating with the transmitter through the USB port . The transmitter may not be able to respond to all requests if both
the EIA-485 and USB programming ports are busy .
EIA-485 / Modbus RTU
See "RCT1000 Modbus RTU Communication Protocol" user manual, available at

.
Optional HART Communication Card
See the "Coriolis Flow Meter HART Bidirectional Communication Protocol Data Access" user manual, available at
www.badgermeter.com
.
Optional Ethernet Communication Card
An optional Ethernet communication card can be ordered on the Coriolis transmitter by including the “E” designation in the
Communication Protocol block in the part number construction .
The Ethernet card supports both Modbus TCP/IP and EtherNet/IP protocols . Configuring the Ethernet IP address requires a
computer with an Ethernet port .
