Expansion Port Appearance
The
NEO
expansion port is on the back of the unit above the battery compartment, and is
normally protected by a press-in rubber cover. The cover should be left in place if the expan-
sion port is not in use.
Removing the cover reveals the expansion port, the two lower threaded anchor points, and
the lower mounting slot. The expansion port comprises 16 small contact pads, and 2 larger
contact pads. The pads are slightly recessed behind a black Mylar mask, which may need to
be removed to ensure a proper connection (see Section 2.7.2 on page 14).

Mechanical Description of the
NEO
Expansion Port
Electrical connection to the pins of the expansion port is made via exposed gold-plated pads.
It is expected that connection between the port and the attached device will be made using
sprung gold-plated fingers.
The recommended connector for attaching to the expansion port is a 16-pin connector from

To ensure proper connection with the expansion port contact pads, it may be necessary to
remove the black Mylar® overlay that surrounds the expansion port. Remove the overlay by
inserting a small flathead screwdriver between the overlay and the case and
carefully
lifting
it off.
