SDZ16
16x16 SD & AUDIO MATRIX
6.6 RECALL OF A PRESET
A previously stored preset can be activated.
The host must send the following sequence:
RNN
followed by
CR
where: R is the character Hex 52
NN is the preset number (from 01 to 16)
Example:
If the preset identified by the number 15 is to be recalled, the host will send the following
sequence on line: 52 31 35 0D
6.7 CREATION OF A PRESET (SAVING CURRENT STATUS)
The SDZ16 can create and perform up to 16 internal presets. A preset is a
predefined configuration of 32 switching points, 16 video and 16 audio, saved
in the memory and which can be recalled at any time.
The presets are created from the current status of the matrix and are
maintained in the case of a blackout.
WARNING
We remind you that SDZ16 allows creating and recalling presets also via
keypad. The presets are superimposed, so the RS232 settings might cancel
or substitute the keypad settings or viceversa.
The host must send the following sequence:
SNN
followed by
CR
where: S is the character Hex 53
NN is the preset number (from 01 to 16)
Example:
If preset 08 is to be assigned to the current state of the matrix, the host will send the
following sequence on line: 53 30 38 0D
The SDZ16 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
