The GRP-500M provided by ICP DAS is a gateway for
Ethernet, serial port and CAN. The GRP-500M can be used
for wireless data transmission and other functions through its
optional 4G / NB communication module. With the optional
GPS module, the GRP-500M can also be used as a GPS
tracking system for vehicle management or maritime system.
It can be used in M2M application to transmit remote I/O, Modbus
data or camera video. Within the high-performance CPU, the GRP-
500M can process large amounts of data in a high-performance
CPU and is suitable for harsh industrial environments.
