Board Edge Connections
All of the connectors are keyed, latched, and have a different number of pins, to eliminate cross-
connections. The physical connectors are Molex Micro-Fit 3.0 style.
Connectors from left to right (top to bottom):
DC Power : J6
1 DC Power Input (+)
2 DC Power Return (-)
3 DC Power Input (+)
4 DC Power Return (-)
5 Low Voltage DC Pwr
6 LV DC Pwr Return
7 Low Voltage DC Pwr
8 Switched Pwr Return
The DC Power Input / DC Power Return signal pairs are connected to the power source for the system,
which can range from 10 to 32 VDC. Only one pair of pins are required to be connected to supply the
DigiSnap 3000, allowing the second pair to be used to ‘daisy chain’ to another device requiring connection
to the DC supply. The DC Power Input and Return signals are electrically isolated from the rest of the
DigiSnap 3000 signals.
Low Voltage DC Pwr is nom8.25V above the LC DC Pwr Return. The total current from theses two
pins is limited to about 1 amp, and is protected by a 1 amp thermal protection device.
The switched return signal is an open drain MOSFET, using a flyback diode to the LV DC Pwr, allowing
control of small inductive devices.
Manual Control : J2
1 Switch #1 Input
2 Switch #2 Input
3 Switch #3 Input
4 Switch #4 Input
5 LED Output
6 Return
For applications that require manual control of the operation of the camera as well as the terminal interface,
the DigiSnap 3000 provides four inputs that can be driven by simple switches (normally open, switched to
Return), or logic level signals from other electronic devices (no5V/High). The switch functions
are configurable within the DigiSnap 3000 menus [Not currently implemented].
The LED output is suitable to directly drive the anode of an LED (cathode to Return), for feedback to the
operator [Not currently implemented].
Remote I/O: J5
1 USB D+
2 USB D-
3 USB +5V
4 USB/Serial Return
5 Strobe Output
6 Strobe Return
7 Video Output
8 Video Return
9 Serial From Terminal
10 Serial To Terminal
These signals are used for interface to the remote operator.
The USB signals are connected through the DigiSnap 3000 board directly to the camera, and may not be
accessible simultaneously with camera serial port control. For use with the Nikon Coolpix cameras, the
operator should set the camera to the ‘Standard’ protocol with the LCD off, before connecting the USB to a
host device.
