* 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
sec]

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
