2.7 NEO Expansion Port

2.7.1 NEO 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).

Figure 2.2 NEO Expansion Port

For detailed pinout information on these pads, see Section 2.7.4 on page 18.

2.7.2 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

Hirose (HRS): product number DF26A1.2-16CP-1.1V(51), part number CL661-0003-8-51.

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.
