(2) Other Terminal Control Considerations
•
Terminal Mode will remain On when you turn the power supply Off or On.
• If the TV is unplugged at the wall outlet, the Terminal Mode will turn Off.
•
If the TV is turned off in normal mode and the Terminal On command is sent, the unit can be
turned on via RS232C.
•
The commands executed in Terminal mode should be executed and displayed after exiting
Terminal Mode.
(3) Command Execution
1- The time delay between 1 byte characters in a command string is 99mS. Any delay
longer than 100mS will be cancelled and the unit will respond with a “NACK” (16H).
2- When transmitting command strings, an ACK or NAK should be sent by the TV. However,
this will not be the case when commands are re-executed or the command does not
execute.
3- The framing delay between continuos commands is 32mS.
4- When communicating with the unit in Terminal Mode, the unit must respond with either
an ACK or an NAK before sending it another command. Failure to do so will result in
commands that are not executed.
5- Please note that when the Power on command is sent to the unit, it will be necessary to
wait 12 seconds before sending any other command.
