Z - Camera Zoom Step size
When using the standard camera protocol (if for instance not supported by the camera, or manually
configured to use the standard protocol), the camera focal length cannot be smoothly transitioned in and
out, but is set to progressively changing focal length settings. The parameter determines the step size used
to change the focal length.
If set to a higher value, then the zoom function is more rapid, but less precise. If set to a lower value, the
zoom may be more precisely set, but will take longer to move.
Note that the actual value used has photographic relevance. The actual focal length change (in mm) is the
entered value / 10.
S - Serial Control of Camera
When using a standard digital camera, where communication is via the camera’s serial port, the serial port
should be enabled. If an SLR type camera is used, where the camera shutter is controlled via a switch
contact, then the serial port control should be disabled, to ignore serial protocol errors.
P - Toggle Protocol
When supported by the camera, the extended protocol is preferentially used, as it allows for smoother
zoom, half-press state, and potentially more accurate image exposure. If desired, the protocol may be
toggled from extended to standard or vice versa. Camera configurations, image review, etc. can only be
controlled remotely via the standard protocol, so the DigiSnap will automatically switch if needed.
Q - Quit to Configuration Menu
Return to the main configuration menu.
DigiSnap Operation Menu
The DigiSnap Operation menu allows configuration of various constants associated with the DigiSnap
3000.
B - Terminal Baud Rate :
The communication to the terminal / GUI can be set to a number of baud rate values. The default is 19.2
Kbaud.
G - CommGap Delay :
Between each serial command exchanged with the camera is a small time gap, apparently required by the
camera. This value is set by the factory to work with most cameras, but is configurable to potentially
address some communication issues.
D - Display Current Settings
All of the DigiSnap configuration values are displayed.
I - Display Device ID
Each DigiSnap 3000 is serialized at the factory, to allow tracking, and distribution of firmware and
features.
