Cable for local controller coupling in the case of hardware handshake
The connection of the CTS to a controller is effected with a so-called zero modem cable. In the case of
this cable, the data, control and report lines must be crossed. The following wiring diagram applies to a
controller with 9-pin or 25-pin configuration.
