AUXILIARY I/O CONNECTIONS
The 6-pin Auxiliary I/O port can be used to interface the GeoSnap with external devices. A 6-pin
locking connector and three wires with pre-crimped pins are provided in the GeoSnap
accessories for this use. To install a wire into the 6-pin locking connector, place the wire into the
appropriate slot with the smooth side of the pin facing up. Push the wire in until you hear a click,
then tug on the wire slightly to ensure that it seated.

3 RS232-out -15 to 15V Not currently operational
4 Trigger 0 to 5V Control GeoSnap by driving this line high (3.3-5V) or low
(0-0.2V)
5 Indication 0 or 3.3V Line goes high (3.3-5V) when capture verification is
received
6 VCC 3.3V Only for use with the Trigger line (position 4). Should not
be used to power any external device.
External Trigger Input
The GeoSnap board can be triggered externally by an autopilot, handheld remote, or other input
by driving Pin 4 high (3.3-5V) or low (0-0.2V), depending on the settings you have chosen in the
configuration file (see options @3 and @7 in the Configuration File section of this manual for
more information). There are two primary ways that this can be done:
Short Together Pin 4 and Pin 6 (recommended)
It is highly recommended that you use Pin 6 to provide the voltage to hold or drive Pin 4 high.
This can be done by simply shorting together Pin 4 and Pin 6 using a switch or relay.
Inject 3.3-5V into Pin 4
You can also inject 3.3-5V into Pin 4 using an external device (e.g. autopilot). If this is the case,
the external device and the GeoSnap must share a ground (Pin 1 can be used for this purpose).
