Appendix: Serial Protocol

All commands and responses are printable ASCII and are terminated with a <CR>

(\x0D).

The serial commands listed here are grouped into front panel functions, verbose

mode functions, and switching/routing functions.

Multiple serial commands cannot be strung together.

NOTE: When programming the MD5x1 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 MD5x1 is to be programmed with

digital and analog switching commands, serial commands should not be used.

Front Panel Functions

Front Panel Lock Commands

COMMAND FUNCTION

L0\r Unlock front panel

L1\r Lock front panel

L?\r Get lock status

If the MD5x1 is in the local mode and the “Lock front panel” is sent, the MD5x1

will switch to the system mode and use the switching schema specified by the

control system. If the MD5x1 is already in the system mode, the operating mode will

not change.

When set via serial command, the front panel lock setting is not retained when power

to the MD5x1 is recycled. To retain the panel lock setting, a digital signal must be

used.

When the verbose mode is on and the lock state changes, or if the MD5x1 is polled

for the status of the front panel lock, the MD5x1 replies with one of the responses

listed in the following table.

Panel Lock Status Replies

MESSAGE DEFINITION

L1\r Front panel is locked

L0\r Front panel unlocked

Verbose Mode Functions

The MD5x1 has a verbose mode, which can be turned on or off via serial commands

only. The verbose mode is used to automatically report any changes made to the

switching schema. The default setting for the verbose mode is off. If the verbose

mode is on, whenever a parameter of the switch changes, a message is sent from the

MD5x1 that indicates the new state of the parameter. If verbose mode is off, the

MD5x1 will only send messages when queried.

The setting for the verbose mode is retained even after power to the MD5x1 is

cycled.

Commands can be sent to the MD5x1 regardless of the status of the verbose mode.
