Command Description
Operation
Video Loss
Detection
Q2 "$A5,<dh>,<dl>,3,'Q2',<video loss mode>" (7 bytes)
Selects response when a loss of video signal is detected
0=Both audio and video muted (default-blue screen for video)
1=Audio muted only
2=Video muted only
3=No muting (do nothing on loss of video)
Tuner Mode S0 "$A5,<dh>,<dl>,3,'S0',<tune mode>" (7 bytes)
Sets tuner mode to standard CATV, Broadcast, HRC, or IRC
0 = CATV
1 = Broadcast/Antenna
2 = HRC
3 = IRC
Tune Ring TR ―$A5,<dh>,<dl>,<ncb>,‘TR‘, [<chan 1>, <chan N>]‖ (variable bytes)
This command stores a Tune Ring, a series of preset channels accessed by channel
up/down commands.
Ex1: ―$A5,<dh>,<dl>,6,‘TR‘, 5,4,8,11‖ sets ring to channels 5, 4, 8 and 11
Tip: The ring follows the stored order, channels do not have to be in ascending order
Ex Ex2: ―$A5,<dh>,<dl>,2,‘TR‘ ‖ clears the Tune Ring, locks unit to current channel
Tip: In the above mode, the IR Keypad channel up/down response to the Head-End, so
the system will know the user is trying to change channels. In response, the
system could change channels on a media sources, like a VCR or satellite.
Ex3: ―$A5,<dh>,<dl>,9,‘TR‘, $82,5,7,$89,13‖ sets channels 2-5, 7, and 9-13. You can
specify a range using MSB bit for the first channel; the next byte is the last.
Channel Labels TN ―$A5,<dh>,<dl>,<ncb>,‗TN‘,<channel>,<label>‖ (variable bytes)
Stores an ASCII string as the channel label. The text will appear briefly when the channel
is selected, if the feature has been activated by IRC Setup command (TM).
Ex1: ―$A5,<dh>,<dl>,6,‗TN‘, 7, ‗PBS‘ ‖ IRC displays PBS when 7 is selected
Ex2: ―$A5,<dh>,<dl>,3,‗TN‘, 7 ‖ Clears alpha label for channel 7
Ex3: ―$A5,<dh>,<dl>,4,‗TN‘,0,0‖ Clears all alpha labels
Display Label TC ―$A5,<dh>,<dl>,2,‘TC‘ ‖ (6 bytes) – Display current channel label for about 15 seconds
Closures Y- ―$A5,<dh>,<dl>,3, ‗Y‘ <I/0 Port>‘ ‖ (7 bytes)
Turns the two internal closures on and off. Closure 1 is typically used to control the
optional buzzer, Closure 2 typically used to control an external camera power relay.
―$A5,<dh>,<dl>,3, ‗Y10‘‖ turns Closure 1 off
―$A5,<dh>,<dl>,3, ‗Y11‘‖ turns Closure 1 on
―$A5,<dh>,<dl>,3, ‗Y20‘‖ turns Closure 2 off
―$A5,<dh>,<dl>,3, ‗Y21‘‖ turns Closure 2 on
Control Lock LM ―$A5,<dh>,<dl>,3,'LM',<control>‖ (7 bytes)
Locks out front panel and IR remote control functions.
Bit 7 Selects IR remote control operation (0=enabled, 1=disabled)
Bit 6 Selects volume control operation (0=enabled, 1=disabled)
Bit 5 - 1 Always 0
Bit 0 Selects IRC front panel buttons operation (0=enabled, 1=disabled)
Device Status SP "$A5,0,0,
2
,'SP'" (6 bytes)
Queries the Head-End for the number of devices present on the network and the number
of devices expected.
