The Scanner - External Sensor

The External Sensor of the Scanner gives you an additional option for doing your data collection. It plugs into the bottom of the base unit and the 20 foot cable allows you to route the small sensor head into tight locations. Since the external
sensor is small in size, it can be used to record data at locations where the main unit cannot be installed, or to allow more covert data collection by hiding the main unit.

Installation
The external sensor screws into the bottom of the Scanner at the External Sensor Port and can be routed to any location you want to count. When aiming the sensor, note that there is a grooved notch on the sensor that should always be facing up. This makes sure that any directional data recorded will be record properly. When the notch is installed facing up, direction one is left to right, while direction two is right to left.

Mounting Options
While it is possible to install the external sensor by itself by simply laying it on a tree branch or other convenient spot, you may find times when the sensor needs to be more securely mounted. For this we provide a mounting block that can be screwed into a post or pole.

In addition to the mounting block, we also provide a mounting plate that can be used in conjunction with the
block to aid installation. The plate can be screwed to a pole or post using the four corner screw holes, or tied to
a tree. The mounting block can then be rotated up or down depending on the angle needed for data collection.

Lens Options
The standard lens of the external sensor will provide excellent results for a range of 1 to 15 feet. However, for
applications that require greater distance, we provide additional lenses.

The lenses are color coded – the standard lens is grey and comes installed on the external sensor. The
separate green lens covers from 1 to 35 feet while the black lens covers from 10 to 50 feet.

If you have the need to use one of the other lenses, it is an easy process to change the lens. Simply unscrew the
standard grey lens from the front of the sensor and screw the replacement lens on, as shown in the pictures
below.

The external sensor of the Scanner plugs into the bottom of the base unit. The 20 foot cable then allows you to route the small sensor head into tight locations. A mounting block, which is included, allows you to easy mount the external sensor to your chosen location.
