4.5. Connecting the Host Computer
The standard data cable is used for a connection between the Assistant or Assistant-S connector
marked HOST COMPUTER and a PC serial port (COMx). The cable length up to 20 m.
We recommend the standard serial cable with Sub-D, 9-pin, male and Sub-D, 9-pin, female
connectors with all pin to pin connection. At least the connection between pins 2, 3, 5, 7 must be
provided. If your computer has the serial COM port of Sub-D, 25-pin connector use the 25-pin / 9-pin
reduction.
