Introduction
Point to multipoint (PTMP) with MODBUS TCP to MODBUS RTU can be performed by using the MODBUS gateway feature
embedded within the Q data radios.
MODBUS TCP to MODBUS RTU - Point to multipoint
MODBUS TCP to MODBUS RTU - Point to multipoint
Connect the PC’s Ethernet port to ETH1 or ETH2 of the radio being configured and using a web browser, browse to the
radio’s configuration page by entering the IP address the unit into the browser’s URL bar. Once the configuration has been
activated, repeat the process for the remaining radio/s.
To access the parameters below, browse to the “Setup” tab and select the “COM1” option under “Configuration”.
Host Application - 192.168.2.10
Port number: 30010
Protocol: MODBUS/TCP
Site A - RTU Destination Address: 192.168.2.17
Site A - RTU Destination Port number: 30010
Site B - RTU Destination Address: 192.168.2.18
Site B - RTU Destination Port number: 30010
Entry Point - 192.168.2.16
(In this topology, the entry point radio is
transparent to the MODBUS TCP data).
No COM port configuration is required.
Remote A - 192.168.2.17
COM1:

Remote B - 192.168.2.18
COM1:
Mode: MODBUS/TCP Gateway
Character Layer and Interface: match the
configuration of the external serial device you
are connecting to the Q data radio’s Serial
Port. The default is 9600,8,N,1 - RS232.
Packet Layer: MODBUS
Protocol: TCP
Protocol Mode: TCP Server
Local IP Port: 30010
Inactivity Timeout: 30 seconds.
MODBUS RTU Timeout: 30 seconds
