ICC1-IR

RS-232 Commands

Ts & Qs

The ICC1-IR responds to Q-series tuning commands as well

Channel Up

TU “$A5,<dh>,<dl>,2,’TU’ ” (6 bytes) – Tunes to next channel up in Tune Ring

Channel Dwn

TD “$A5,<dh>,<dl>,2,’TD’ ” (6 bytes) – Tunes to next channel down in Tune Ring

TU and TD control analog channels stored in the TR command – designed for legacy

Smart TV installs, not contemporary HDTV applications

T Channel Prev TP “$A5,<dh>,<dl>,2,’TP’ ” (6 bytes) – Tunes to previous channel in Tune Ring
Force Channel

TC “$A5,<dh>,<dl>,3,’TC’, <channel>” (7 bytes) – Tunes to a specific channel

Select Channel TT “$A5,<dh>,<dl>,2,’QT’,<channel>” (7 bytes) – Tunes channel if included in TR
Tune Ring

TR “$A5,<dh>,<dl>,<ncb>,’TR’, [<chan 1>, <chan N>]” (variable bytes)

This command stores a Tune Ring,

Analog channels only

, 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

Ex2: “$A5,<dh>,<dl>,8,’TR’, $82,5,$87,11” sets channels 2-5 and 7-11. You can
specify a range using MSB bit for the first channel; the next byte is the last.

Control Lock

LM “$A5,<dh>,<dl>,3,'LM',<control>” (7 bytes)

Locks power operation – only functional with display with power current sensor.

When the control is locked, the display is locked to the power state of the ICC1-IR.

For example, if the ICC1-IR power state is off, the display can’t be turned on from

the IR remote or TV front panel. The controller will sense the change from the

power sensor and turn the set off.
0 = Unlock, 128 = Lock

Tuning Style

H1=

“$A5,<dh>,<dl>,3,’H1’,<style>” (7 bytes)

1 = 5-digit CableCard style tuning (1-9999)

2 = Virtual HD Major-Minor tuning (tunes to virtual channel ID in display)

3 = Physical HD Major-Minor tuning (physical channel, minor digital)

TC Response

H2=

“$A5,<dh>,<dl>,3,’H2’,<response>” (7 bytes)

This pre-sets how the ICC1-IR will respond to TC tuning commands.

0= Ignore, use current settings

1= Analog Only (XX-0)

2= Digital (XX-1)

Tune HD

TH


Ex:

“$A5,<dh>,<dl>,5,’TH’,<H1>,<Major>,<Minor>” (9 bytes) – Digital Tuning

Normally, the H1 parameter is 0, allowing the ICC1-232 to use the current H1 tuning

format, but it could be used to force a different tuning option. When the display is

set to the H1=1 mode, 1-part digital channel, the first byte is (x*256), and the last

byte is the value you add to state the channel number. In H1=2 or 3 modes, the

bytes represent the Major and Minor channel numbers.


This command is designed for compatibility with other ICC controllers. In reality, H1

modes 2 and 3 are the same for IR control.

“$A5,1,4,5,’TH’,1,2,3” Device 260, channel 515

“$A5,1,4,5,’TH’,2,2,3” Device 260, virtual channel 2-3

“$A5,1,4,5,’TH’,3,2,3” Device 260, physical channel 2, minor 3
