2.3 The pin definition of physics interfaces
2.3.1 PIN definition of RS-232 port
The Decoder has one RS232 standard serial interface, with RJ-45 connector. Its pin definition
is as follows (‘I’ means input, and ‘O’ means output):
(1) When the RS232 interface of the DVS connects with the DTE equipment, one end of the
cable is the 8-pin RJ45 connector (to DVS) and the other of the cable is the DB25 female
connector (to DTE). Below is the description of the internal connection between RJ45 and DB25.
(2) 25-pin to 9-pin converter’s internal connection is like this:
