7.12 Set Preview audio and video
TZ09 connects the selected video and audio inputs to the preview outputs.
The host must send the following sequence:
bXX
followed by
CR
where:
b is the character Hex 62
XX is the video and audio input (from 01 to 08)
Example: to set inputs 1 video and audio to preview outputs the following characters
must be sent on line: 62 30 31 0D
The TZ09 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
7.13 Set Volume level
TZ09 can set the audio preview level.
The host must send the following sequence:
lXX
followed by
CR
where:
l is the character Hex 6C
XX is the desired level (from 01 to 08)
Example: to set audio volume to level 3 the following characters must be sent on line:
6C 30 33 0D
The TZ09 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
7.14 Set mute on audio preview
TZ09 can set mute on audio preview level
The host must send the following sequence:
mX
followed by
CR
where:
m is the character Hex 6D
if X is 0: mute not active
if X is 1: mute active
Example: to set mute audio the following characters must be sent on line:6D 31 0D
The TZ09 matrix replies:
ACK
(Hex 06) if the command has been performed correctly
NACK
(Hex 15) if transmission errors have been detected
WARNING
In case of multiple commands
wait 150msec through the strings of characters
3.0 SETTINGS
The unit has two types of internal settings:
3.1 Insertion or removing of the 75
Ω
internal termination on the inputs
To perform this operation:
a) Unplug the mains cable from the unit
b) Remove the cover of the unit
c) Position jumpers W1
÷
W8 on the rear circuit board to the ON or OFF position
for each input to be terminated at 75
Ω
.
WARNING
W1 corresponds to input 1, W2 corresponds to input 2,
and so on for the other inputs
d) Replace the cover of the unit
e) Reconnect the mains cable.
WARNING
The 75
Ω
must be left inserted internally (jumper ON) when
the loop is not used and there are no external BNC terminations
For use of the loop in input or of external BNC terminations
it’s necessary to set the jumpers in OFF position.
The unit is factory set with jumpers W1
÷
W8 in the ON position
(75
Ω
termination inserted)
