Power-Up and Lock Logic
The ICC1-232 remembers the current power and Lock state of the connected TV so that the controller can restore power
and operation lock to the TV when AC power is restored. Some TVs, such as LG, will lose the locked state (no local button
or IR control) when the set loses AC power. Other sets may not automatically power back on when AC power is restored.
To deal with this issue, after every power-up or reset, the ICC1-232 will transmit its current (last commanded) power
control string (Power On or Power Off) to the TV, as well as work to restore the Lock state.
If the TV was On and Locked when power was lost, the controller will send a Power On command when power is restored,
then sends a Lock command after a time delay. This assures that the TV stays locked when it is automatically powered up
after a reset.
If the TV was Locked and Off when power was lost, the controller will send a Power Off command every 16 seconds when
power is restored. When a command is sent to turn the TV on, the controller will also send a Lock command after a time
delay.
Input Selects
The code sets listed a Contemporary TVs in the list on Page 5 have the ability to select inputs from a special channel
command, 0-NNN. For example, a 0-211 command would send the TV to the HDMI 1 input. For some makes, such as LG,
you need to send a TV/Tuner command (0-200) to restore the TV to the current channel. For other sets, sending a channel
command automatically selects the tuner if it's at a different input. The command list covers all the possibilities, not all
sets have every option.

models. A codeset is available for older models as well.

• E-Series TVs with AVT tuner

The current codeset is for previous prosumer Sharp TVs that supported RS-232 control.
• Send and H9.1 command via DX or control system for sets that can tune XX.1 channels
• Send an Off command to all TVs, manually turn on TVs, then send an OFF command – this turns off
the Energy Star feature that turns off RS-232 when the TV is off.
• All commercial models are supported.
