MNU IS series sensors use standard Modbus RTU protocol (RS-485). The sensors can only operate as slave
devices. Sensor default transmission settings are
9600 Baud , 8 Bits , 1 Stop Bit , No Parity , and require a
minimum delay of 200-300 ms between transactions to return the contents of all registers. Commands re-
turning fewer registers will require shorter delays. See MNU IS Modbus Register Lists on pages 10 - 11.

NOTE : For more information about Modbus RTU, please visit www.modbus.org.
MNU IS Modbus series sensors can be programmed, controlled, and monitored via the Internet (or local
Ethernet) using an RST-5003 web-enabled Modbus master controller or LOE web-enabled Modbus master
sensor. One RST-5003 or LOE can control and monitor up to 10 APG Modbus-equipped sensors. Please refer
to the RST-5003 User Manual or LOE User Manual for further instructions and help setting up and operating
an RST-5003 or LOE and using either one to program and control MNU IS sensors.
