Installation of EM Modules onto the EM2 Expansion

Board

The EM2 expansion board has a primary EM header (MOD1) and a secondary EM header

(MOD2) as indicated on the silk screen (see Figure G-5). The secondary EM header is rotated 180

degrees from the primary EM header.

There are many types of EM modules that can be installed onto the EM2 expansion board. See

the README First document for the EM module you are installing to determine if there is a specific

requirement or recommendation for which header the EM module should be installed in. If

installing a single module and if there is no specific requirement or recommendation in the

module’s README First document indicating which slot it should be installed in, install the single

module into the primary EM header (MOD1).

To install an EM module into the primary module EM slot of the EM2 expansion board, do the

following:

1. Attach any supplied antennas to the EM module.

2. Locate the two 20-pin sockets on the back side of the EM module. Note the tab on the side of

each of the 20-pin sockets. This tab denotes pin 1 and aligns with the 20-pin headers on the

EM2 expansion board that contain slots near pin 1 for the tab. See Figure G-5 for details.

3. Align the two 20-pin sockets on the EM module over the 20-pin headers on the EM2

expansion board that are within the primary EM silkscreen.
