Conflicts for the Bit I/O Unit
The following I/O features of the DS1104 conflict with the Bit I/O unit:
Conflicts for the Serial Interface
The master PPC of the DS1104 supports only one serial interface. It
can be configured as either RS232 or RS422/RS485 transceiver.
Conflicts for External Triggering
Enabling the external trigger conflicts with the slave DSP bit I/O unit.
You cannot use the following bits for digital I/O purposes at the same
time:
