8.4.4) RS232 CONNECTION
If a RS232 communication line is shorter of 5 mt. and a multidrop network will not use, it's not
necessary to use a serial line converter because the serial output is compatible with the PC, as shown
on the above mentioned picture.
A RS232 could reach 15mt. but the presence of noises in the industrial application could cause
breakdown in the communication.
The connection from ANR serial port RS232 to PC RS232 serial port is a PTP, Pin To Pin, connection.
