Note 1: The power output set point is a 16-bit value, but only 12-bits are used. The 16-
bit value should be shifted right four bits, and the remaining four bits filled with 0
(zero). All poll commands and response messages are scaled so that 0FFFh = full-
rated output.
Note 2: PO = Power on off:
• 0 = Power off (turns output off)
• 1 = Power on (turns output on)

Note 1: Forward power sense is a 16-bit value, but only 12-bits are used. The 16-bit
value should be shifted right four bits, and the remaining four bits filled with 0 (zero).
All poll commands and response messages are scaled so that 0FFFh = full-rated
forward power.
Note 2: Reflected power sense is a 16-bit value, but only 12-bits are used. The 16-bit
value should be shifted right four bits, and the remaining four bits filled with 0 (zero).
All poll commands and response messages are scaled so that 0FFFh = full-rated
reflected power.
