FP Data Packet

When the RE-350is in [NOTIFICATION] Mode, it will send the “FP Data Packet” to the PC. This tells the condition of each button and control knob every time the condition varies.

The bit assignment of the parameter is as follows:

D15	D14	D13	D12	D11	D10	D9	D8
W/B Vol	0	Focus Auto	B/W	W/B Auto	Nega	Inputselect	0
D7	D6	D5	D4	D3	D2	D1	D0
Detail Vol	EXP Vol	Back light	Lights	Zoom Tele	Zoom Wide	Focus Far	Focus Near

If a control knob has not been used for longer than 500 milliseconds, the RE-350will send the “FP-Data Packet” with the corresponding control knob bit cleared.

Note: If the RTS signal line of the PC is off and the RE-350is in [NOTIFICATION] Mode, the RE-350will start to send the “FP-Data Packet” which explains the button and control knob condition at the time when the RTS signal line comes on.
