MULTI-TASKER™

Check the last three digits against the numbers
above to determine if the MENU MODE option
is available.

Command Format: [?CnUi]

Cn = Card ID (n = # from 1 to max slots)

Ui

= Unit ID (i = from 0 to 9)

Example:

The 

MT105-120

 in slot #4 has Input 1

connected to all outputs and all outputs turned
ON. Send the command [?C4] to receive the
feedback status.

Each status field begins with a '+' and ends with
the card slot number (ex: C04). The feedback
will be similar to the following:

[+MT105-VR690-0170-003C04
+ON1111MA0101010101010101C04
+SI1000SO11111111C04]

MT105-120

= Card Type

VR690-0170-003

= Firmware version

ON11111111

= Output ON/OFF status

MA01010101010101 = Matrix I/O connections

SI10000000

= Input Signal Detect

SO11111111

= Output Signal Detect

The ON/OFF line is read from left to right,
outputs one through eight. A "1" indicates the
output is ON, a "0" indicates the output is OFF.

The I/O connections are also read left to right
representing outputs one through eight and the
input to which each is connected. The first two
digits are the input to which Out 1 is connected.

The Signal Detects read left to right in
increasing order as well. The Input Signal
Detect  shows Input 1 has an active signal at
the input, but inputs 2 thru 7 do not. The Output
Signal Detect shows all 1's indicating there is
an output signal present on all the output
connectors since Input 1 is connected to all
outputs and the outputs are enabled.

5.  

[STA]

This command enables and disables automatic
feedback from the front panel. The command
affects any card with auto-feedback capability,
not just the 

MT105-120/121

. The default at

power on or reset is STA0, OFF.

Command Format [STA1] = ON
Command Format [STA0] = OFF

=

Card slot number

Reading from left to right, the first two digits
represent the input number connected to
Output 1. In this case, Input 1 to Output 1. The
next two digits are for Output 2. In this case,
Output 2 is connected to Input 3. The remaining
Outputs are all connected to Input 1.

=

Card slot number

Reading from left to right, the first digit
represents the status of Output 1. A "1"
indicates ON and a "0" indicates OFF. In this
case, Output 1 is ON and the remaining
Outputs, 2-8, are OFF.
