FP Data Packet
When the
RE-350
is in [N
OTIFICATION
] 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:
W/B Vol 0 Focus Auto B/W W/B Auto Nega Inputselect 0
D15 D14 D13 D12 D11 D10 D9 D8
Detail Vol EXP Vol Back light Lights Zoom Tele Zoom Wide Focus Far Focus Near
D7 D6 D5 D4 D3 D2 D1 D0
If a control knob has not been used for longer than
500
milliseconds, the
RE-350
will 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-350
is in [N
OTIFICATION
] Mode, the
RE-350
will 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.
