Overview
The SnapUSB is a DigiSnap 2000 series accessory, routing the USB and serial
port signals from the camera to a computer and DigiSnap respectively without
having to plug and unplug cables.
The intended applications include microscopy, astrophotography, copystands,
and other stationary applications where image download to a computer is desired.

Connections
•The custom SnapUSB cable is connected between the camera and the
Snap USB box.
•The DigiSnap 2000 can be directly connected to the SnapUSB, or a
standard serial cable can be used to link them together.
•The SnapUSB uses an industry standard USB type B connector to
connect to a computer USB port. A 10 ft cable is supplied.
DigiSnap Configuration
In order to use the SnapUSB, the DigiSnap controller must be configured to
support it. Connect the DigiSnap to a terminal as per the DigiSnap 2000 user
guide.
•Disable the ‘Power Savings’ option (operation menu).
•Configure one of the buttons on the DigiSnap to ‘Turn the DigiSnap
Off’ (switch menu). Most of the SnapUSB applications will not require
Time-Lapse operations, so that button might be the most suitable.
•If you find the switching operation to be unreliable, you may try
increasing the ‘PowerUpDel’ value.
Operation
With all connections established and the DigiSnap off, the computer should
recognise when the camera is turned on.
Wake the DigiSnap up by pressing any button for ½ second or so. This will turn
off the USB connection to the computer, and the DigiSnap will connect to the
camera. All DigiSnap operations will work normally.
When desired, shut the DigiSnap off (pre-configured button). This will allow the
camera to re-establish connection to the computer.
SnapUSB –User’s Guide

How it Works
When the DigiSnap is active, the SnapUSB prevents the USB +5V signal from
the computer from reaching the camera, so that neither the camera nor the
computer realize that the USB connection is made. When the USB port on the
camera is not active, the serial port can be used for remote control.
When the DigiSnap is shut off, the serial port is de-activated, and the USB +5V
signal is applied to the camera, establishing the USB connection.
Problem Resolution
USB is a hot-pluggable system, where the connection may be connected and
disconnected at will. It is possible that some computer systems may not reliably
handle repeated connection and disconnection of the USB signal, but this is of
course out of our control here at Harbortronics. If you find your setup to be
unreliable, connect the camera directly to the computer USB port using the cable
supplied by the camera manufacturer. Try repeated connection and disconnection
of the USB cable to determine if the problem is related to your computer system.
If a problem appears to be related to the SnapUSB, please contact Mark at
Harbortronics.
