Antenna description

The Digi Connect Wi-SP is available with 1 RP-SMA connector. The antenna is connected to the product
with a reverse polarity SMA connector (sub-miniature size A). The antenna fits on the product one way
only to ensure a proper connection. Another option for both signal reception and design flexibility is to
use a 30cm antenna extension cord (Digi part number DC-ANT-E-24DP) with .5dB loss to separate the
antenna from the product.
CAUTION! This FCC Part 15 Class A radio device operates on a non-interference basis with
other devices operating at this frequency when using the antennae listed in the Antenna
Specification table. Any changes or modification to the product not expressly approved by Digi
International could void the user's authority to operate the device.
