PMDX-108 Input
« on: May 13, 2020, 07:10:26 AM »
Can the PMDX - 108 input board be used with the PMDX 422 to increase the number of inputs and if so what would be the correct way to connect them?

No.  The "parallel port" pins that the PMDX-108-Input drives are the PMDX-422's dedicated step and direction outputs on the ribbon header.

Probably buy another I/O board (POKeys, etc).  The PMDX-422 doesn't appear to have any expansion capabilities.
