* Yes the power ON command is correct and is the only command that uses this unique syntax structure. The power

on command OKOKOKOKOK must have a delay of 0.001 sec between each character so:

O[0.001sec]K[0.001sec]O[0.001sec]K[0.001sec]O[0.001sec]K[0.001sec]O[0.001sec]K[0.001sec]O[0.001sec]K[0.001

Crestron Users

If using with a Crestron module The power on command OKOKOKOKOK must have a delay of

0.001 sec between each character so:

O[0.001sec]K[0.001sec]O[0.001sec]K[0.001sec]O[0.001sec]K[0.001sec]O[0.001sec]K[0.001s

ec]O[0.001sec]K[0.001sec]

So in Crestron language the power on command is:

OKOKOKOKOK\x0D\x20

With a 1 Tick delay between each character
