1W RS232 RS485 Wireless Radio Modem Modbus DTU PLC Communication
1W Wireless Radio Modem 1W RS232 RS485 Modbus DTU PLC Wireless Communication
General Introduction
LS-R324 wireless DTU whose transmission distance reaches 3km LOS, supports wireless communication between Siemens S7-200, S7-300 series PLC, Schneider PLC, Mitsubishi PLC, ABB PLC etc. LS-R324 supports Modbus protocol, including Modbus ASCII and Modbus RTU protocol, PPI protocol.
LS-R324 DTU can also connect with VFD, HMI, PC for wireless communication. It supports point to point, point to multi-points wireless data transmission. Wireless solution has the advantage of keep users from wiring cables in dangerous field, easy to set up, no need program knowledge. It is a reliable and competitive solution.

About the LED indicator
a. When module is power on, POWER LED is always ON (red).
b. When module enter to set mode (DIP 8 ON), SET LED is always ON (red).
c. When module is transmitting,
if you use RS232 port, RS232 LED blinks (green) regularly.
if you use RS485 port, RS485 LED blinks (green) regularly.
if you use USB port, USB LED blinks (green) regularly.
d. When module is receiving, RF LED blinks (blue) regularly.
