Connectors: Antenna
The Digi Connect Wi-EM has 2 RP-SMA antenna connectors labeled P2 and P3.
Wi-EM Antenna Connectors
The antenna is connected to the module with a reverse polarity SMA connector (sub-
miniature size A). The antenna only fits on the module one way to ensure a proper
connection. Another option for both signal reception and design flexibility is to use an
antenna extension cord (Digi part number DC-ANT-E-24DP) to separate the antenna from
the module. This allows the module to fit inside your product but the antenna to be placed
outside the device.
