Serial system interface
A standard cable for connecting printers to the serial interface is used
to connect the ND77 to a PC or a PC-compatible unit (e.g. BEETLE
Systems).
This cable has a 25-pin D-sub connector on the end connecting to the prin-
ter. At the end connecting to the system it has a 9-pin D-sub connector
male or female depending on the systems interface.
If you are connecting to a BEETLE system with voltage-supplied COM
interface, your local branch office can supply you with the appropriate
cable. Gender-changers must not be used.
The following illustration shows the connector pin allocation and connecti-
on of the cable.
