interface
The serial port is male (needl), RS232 level (can be directly connected to computer serial),
part of RS232 pin sequences consistent to computer COM port. When connected with the
computer, we need to use cross cable (2-3 cross, 7-8 cross, 5-5 direct, 7-8 can don ’ t connect, but
musn ’ t direcly connect to computer . Otherwise, it might lead to irregularly work).
The DB9 interface contains the RS232, RS485 and RS422 interfaces.
