QM-MD7x2, Slot 1 Serial Input Signal Descriptions
INPUT DESCRIPTION
Control$
Accepts serial commands for routing signals. Allows
users to query the switch for current status. Refer to
“Appendix: Serial Protocol” on page 84.
NOTE:
When programming the MD7x2 using serial commands, digital and analog
switching commands should not be used. However, digital and analog mixing
commands can still be used. Similarly, if the MD7x2 is to be programmed with
digital and analog switching commands, serial commands should not be used.
