D30/31 Mode

The D70/P parameters that correspond to the Wide and
the Tele end of the D30/D31 are approximately 0000h
and 3B4Bh. However, at the Wide end, the horizontal
viewing angles are 48.8˚ for the D30/D31, and 48.0˚
for the D70/P.

Received parameters (0000h ~ 03FFh) will be
converted within a range of 0000h to 3B4Bh. For D30/
D31 mode, the setting will normally be Digital Zoom
OFF

However, for CAM Zoom Tele/Wide commands and
operations from the remote control, movement within
the over all limits of the D70/P Zoom (0000h ~ 7AC0/
77C0h) is possible.

Translation

0000h to 03FFh

Translates within a rage of 08D0h to 5700h

The EVI-D70/P translates the parameters to let the
camera obtain the same zoom position that is defined
by the D30/D31’s parameter.

(The values given below are calculated values.)

Parameters

Translation

0000h to 4000h

Translates within a rage of 0000h to 03FFh

The D70/P’s parameters are translated to those of the
D30/D31.
However, even if the zoom position value is less than
08D0h (closer to the wide side), the camera sends back
0000h to the controller. On the other hand, even if that
value is greater than 3B4Bh (closer to the telephoto
side), the camera sends back 03FFh.

Because the range of the D70/P is narrower than that
of the D30/D31, emulation is not carried out to match
the actual focus position (focal point) to that of the
D30/D31.
The EVI-D70/P operational range of (1000h (FAR) ~
C000h (NEAR, 1cm)) is emulated within the
operational range of the EVI-D30/D31 (1000h (FAR)
~ 9FFFh (NEAR, 1cm)).
