Tuning
Tuning Format
S0=
“$A5,<dh>,<dl>,3,’S0’,<format>” (7 bytes)

–
When the ICC2-ATSC 4 receives an analog channel command, it will attempt to tune the digital
equivalent first. If there is not a matching virtual channel, the unit will tune the analog channel.
Channel Up
TU
“$A5,<dh>,<dl>,2,’TU’ ” (6 bytes) –
Tunes to next channel up
Channel Dwn
TD
“$A5,<dh>,<dl>,2,’TD’ ” (6 bytes) –
Tunes to next channel down
Prev Channel
TP
“$A5,<dh>,<dl>,2,’TP’ ” (6 bytes) –
Tunes to previous channel
Tune Analog Channel
TC
“$A5,<dh>,<dl>,3,’TC’, <channel>” (7 bytes) –
Tunes to a specific channel 2-127
Scan Mode
D0=
“$A5,<dh>,<dl>,3, ‘D0’,<mode>” (7 bytes) –
Scan Mode
Sets scan mode for digital and analog channels from the T^ or front panel scan command.
0= Scans for analog and digital channels scan (default)
1= Scans for digital only, deletes analog channels
2= Scans for digital only, keeps analog channels
3= Scans for analog only, deletes digital channels
4= Scans for analog only, keeps digital channels
Channel Scan
T^
“$A5,<dh>,<dl>,2,’T^’ ” (6 bytes) –
Initiates channel scan
Tune HD Channel
TH=
Ex:
“$A5,<dh>,<dl>,5,’TH’,<H1>,<Major>,<Minor>” (9 bytes)
The tuner will ignore the first bit (H1), and tune the major (virtual) and minor channels. Values may
be in hex or decimal.
“$A5,1,4,5,’TH’,0,2,3” Device 260, virtual channel 2
-3
The LQ command and TH 0-xxx (p7) can select inputs

1=Captioning on
Caption Mode
Q1=
“$A5,<dh>,<dl>,3, ‘Q1’,<mode>” (7 bytes)
1=Caption 1 (normal setting for most captioning)
2=Caption 2
3=Caption 3
4=Caption 4
5-8= Text 1-4 (rarely used)
Volume
V9=
Check with CR Support to see if Control Type supports external volume control
0=Tuner volume
1=External volume (such as video projector)
