g) Get the status of zoom position

:RFC9100

If echo back data is not “FF”, zoom position

is calculated by following equation.

zoom position = 22X256/(XX+1)

XX; echo back data

If echo back data is “FF”, then following

commands should be sent.

:rF7200000

Echo back data shows zoom position.

[Please refer to the attached Table.1.]

Table.1 Zoom position data table (reference value)

Zoom position X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11

h) Switch the continuous digi. zoom ON/OFF

:RFCCB00

:WFCCBX

X1X0=00 ; OFF X1X0=01 ; ON (default)

Please attached Continuous digi. zoom flow chart.

i) Set the maximum mag. tuning value in continuous digi. zoom ON mode

:WFDF0X1X0

X1X0 (hex) = {256-(256/MM)} (dec)

MM; maximum mag.

[ EX. mag.1; MM=1 X1X0=00

mag.2; MM=2 X1X0=80 ; max. (default)

j) Switch the instant digital zoom ON/OFF

:RFF0F00

:WFF0FX

bit 7 of X

: 0-OFF(default) 1-ON

k) Set the instant mag. tuning value in instant digi. zoom ON mode

:WFDE6X

X1X0 (hex) = IMX10(dec)

IM; instant mag.

(more than 1.0 and 0.1 step)

[ EX. mag.1; IM=1.0 X1X0=0A

mag.2; IM=2.0 X1X0=14 ; max. ]
