2. RS232/422 Specifications and Wiring

 

a.  With “UART + 2 Digital 2 Digital Input” Converter   

There are two terminal blocks at each side of the Gateway, one is 9 Pin 

terminal block and another is 13 Pin terminal block. The 1

st

 pin of the 9 

Pin terminal block is neighbor the RJ-45 Ethernet connector and the 1

st

 

of the 13 Pin terminal block is neighbor the 2PIN DIP Switch. Please 

see below is the Pin layout of the Gateway..   

 

 

 

 

Connector and Pin Descriptions: 

 

RJ-45 

It is an 8 Pin RJ-45 Ethernet connector; it is connected to the 

Ethernet Hub or another Host via Ethernet CAT-5 cable. The data 

rate can be 10/100MHz. 

 

9 Pin Terminal Block 

This connector offer two UART port connection, the pin 

description is in the following table.
