board. This design is identical to the push-to-talk configuration, without support for
microphone input.

Expansion Ports
Omnii includes three designated “expansion ports” that expose standard GPIO, serial and USB
interfaces for expansion modules. Each expansion port operates independently of the other two,
allowing up to three expansion modules to be connected at the same time.
The three expansion ports are located as follows:
•
Expansion Port 1: End-Cap Connector (see Section 6.4.2: “Expansion Port 1 (End-Cap
•
Expansion Port 2: Pod Expansion Connector (see Section 6.4.3: “Expansion Port 2 (Pod
•
Expansion Port 3: Multi-Function 100-Pin Connector (see Section 6.4.4: “Expansion Port 3
(100-pin Multi-Function Connector)”)
Figure 6.11 Location of Expansion Ports on Omnii Main Logic Board
Note: If a GPS/WWAN module is installed in the 100-pin socket, the pins for expansion port 3 are
passed through to a 22-pin connector on the back of the module. In this case, the pinout for
expansion port 3 is the same as for expansion port 2.
