2.3.1 Main/Aux. Serial Interface and I/O Connector

The DX6400/DX6500 master/slave model is equipped with a 25-pin male D-sub connector
for connection to the host computer, power supply and input/output signals.
The DX6400/DX6500 Ethernet models adopt a 26-pin male connector instead of the 25-pin
one.
The details of the connector pins are indicated in the following table:
