ABB 500NMD20 - Serial Interfaces (Con0 - Con1)

Device description Connections
ADVICE
Any SHDSL port supports auto-crossover detection and correction, so signals A and B may
be interchanged.
ADVICE
The signal lines are short-circuit protected and may be connected while the module is
powered and working.
4.7.4 Serial Interfaces (Con0 - Con1)
The serial interfaces of the devices are signal compatible to RS-232. The connector is a RJ-12
female plug. The factory pre-sets are speed 57600 Baud, no parity, 1 stop bit, no flow control.
On delivery, the management console can be accessed via the serial interface.
