Serial Port Data Acquisition
RS232/RS485 interface can be externally connected to any sensor device, including
temperature and humidity sensor, gas sensor, speed sensor, soil sensor, pressure sensor, liquid
sensor, transmitter and motor protection sensor, etc. Also can be connected to various
instruments, PLC device and other external equipment like camera, can be arbitrarily selected
according to customer's demand.RS485 interface can be connected to multiple the same or
different device, supports up to 48 devices in series.
As long as the external device have RS232 or RS485 interface, in theory, our RTU serial port
can be connected.
