Connectors: Power and Serial Interface
The antennae are connected to the module with reverse polarity SMA connectors (sub-
miniature size A). The antennae fit the connectors on the module only one way to ensure a
proper connection. The antennae function best when placed perpendicular to each other
(one straight, the other up or down) to prevent interference from each other.
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.
This single 12-pin, serial interface port (labeled P4 for Digi Connect EM and P5 for Digi
Connect Wi-EM) supports 2 TTL serial interfaces, data rates up to 230 Kbps and full-
modem control (on port 1). See the figure for help locating pins and the table for pin
assignments.
