Command
Description
Tuning
Tuning Format
S0=
“$A5,<dh>,<dl>,3,’S0’,<format>” (7 bytes)
0=CATV
1=Off-Air
2=IRC
3=HRC
4=Cable Auto
Tuning Style
H1=
NA
TC Response
H2=
NA – When the ICC2-ATSC 4 receives an analog channel command, it will
attempt to tune the digital equivalent first. If there is not a matching virtual
channel, the unit will tune the analog channel.
Channel Up
TU
“$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.
“$A5,1,4,5,’TH’,0,2,3” Device 260, virtual channel 2-3
See page 12 on how to use TH to select inputs
Add Channel
XA=
“$A5,<dh>,<dl>,5, ‘XA’,<chan Major>,<chan Minor>,<RF physical channel>”
(9 bytes) – adds channel to tune ring/list
Delete Channel
XD=
“$A5,<dh>,<dl>,4, ‘XD’,<chan Major>,<chan Minor>” (8 bytes) – Deletes
channel from tune ring/list
Tune Control
Q9=
“$A5,<dh>,<dl>,3, ‘Q9’,<control>” (7 bytes)
0= Tune any channel
1= Only tune channels from the tune ring/list
Captions
Q0=
“$A5,<dh>,<dl>,3, ‘Q0’,<on-off>” (7 bytes)
0=Captioning off (default)
1=Captioning on
Caption Mode
Q1=
“$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)
