7.11 SWITCHING THROUGH BLANK TIME REQUEST
The host must send the following sequence:
w
followed
by
CR
where:
w is the character Hex 77
The matrix replies:
Y
time set for output 1
(from 0 to 3)
Y
time set for output 2
(from 0 to 3)
“ “ “ “ “
“ “ “ “ “
Y
time set for output 12
(from 0 to 3)
the time indicated by Y may be equal from 0 to 3
0 = 0.3 sec.
1 = 0.5 sec.
2 = 1 sec.
3 = 2 sec.
CR
Example: a reply of the type 30 30 30 30 30 30 31 30 30 30 30 30 0D indicates that output
No. 7 has a switching time of 0.5 seconds while all the other outputs switch in 0.3 seconds
7.12 SET PREVIEW OUTPUT
The host must send the following sequence:
pX
followed
by
CR
where: p is the character Hex 70
X
shows
if
the
output
12 must be used as preview:
1 = output 12 is preview
0 = output 12 is a standard output
The TZM1612 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
Example: To set the output 12 as preview the host will send the following sequence: 70 31 0D
7.13 SET MUTE ON PREVIEW OUTPUT
When output 12 is used as preview it's possible the setting of a MUTE on it.
The host must send the following sequence:
mX
followed
by
CR
where: m is the character Hex 6D
X shows the type of MUTE on the preview output:
0 = mute OFF
1 = mute Audio
2 = mute Video
3 = mute Audio + Video
The TZM1612 replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if output 12 had not been previously defined as preview or if transmission
errors have been detected
Example: to program the MUTE audio on preview the host will send the following sequence:
6D 31 0D
