Connectors of 50-Pin-to-4x9-Pin Frontpanel Adapter

In order to provide separate serial I/O channelling, a four-channel frontpanel adapter
(CP-ADAP-CP345-DSUB50) can be connected to the 50-pin frontend connector of the
optoisolated board variant. 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 50-pin and 9-pin DSub connectors are shown in the following table.
Warning!
Where signals are not indicated in the below table, please do not
connect external wiring to the connector pins. Failure to comply
may result in damage to your board.
