INSTALLATION 2
2.3.1 Main/Aux. Serial Interface and I/O Connector
The DX6400 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 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:
