device and the serial port server.
2) Built-in lightning protection of power supply: built-in pressure sensitive resistance
and ceramic discharge tube can effectively protect the internal circuit of serial
device server in the case of power surge.
3) Industrial power supply: it has two kinds of power supply connection modes:
terminal and power plug. Can be 9~48V wide voltage power supply.
4) It has three serial port interfaces of RS232/485/422.
5) RS485/422 has capacity of 256 loads.
6) Ethernet port with 2KV surge protection.
7) Abundant panel indicator lights are convenient for debugging: in connection,
there is not only a 100M_LINK light indicating whether the network line is
connected, but also a LINK light indicating the establishment of TCP connection.
Data indicator light has independent indicator light for "serial port to Ethernet port",
"Ethernet port to serial port". Convenient for site debugging.
