The central unit has one feedback input, for incremental signals (TTL, differential TTL, Vpp).
Connector pinout.
Cable characteristics.
We recommend to run the feedback cables as far away as possible from the power cables
of the machine.
The cable being used must have overall shield. The cable shield must be connected to the
metallic hood at each end. The unshielded portion of the wires of an unshielded cable cannot
be longer than 75 mm.
Plug-in part. 15-pin male SUB-D HD type connector.
Connect the cable shield to the connector housing at both ends.
