2.4.1.2 Connectors of 37-Pin-to-4x9-Pin Front Panel Adapter
In order to provide separate serial I/O channelling, a four-channel front panel adapter cable can
be connected to the 37-pin front panel connector. This adapter terminates on the user side with
four male 9-pin D-Sub connectors which include the signals of channels 0 to 3. The pinouts of
the adapter’s 9-pin D-Sub connectors are shown in the following table.
Warning!
Where signals are not indicated in the table below or marked with NC,
please do not connect external wiring to the connector pins. Failure to
