Digi Connect Wi-SP Overview
LEDs
Digi Connect SP and Digi Connect Wi-SP have three LEDs. Two LEDs are connected directly to
the hardware; the other is software programmable. See the following table for more information.
LED Descriptions
LED Color Purpose
Power Red (labeled PWR)
This LED is software programmable. The default is that
this LED indicates power (and is therefore always on).
See “LEDs” on page 15 for more information
Link Green
Network link status:
– On - unit is associated with an access point
– Blinking slowly - unit is in ad hoc mode
– Blinking quickly - unit is scanning for a
network
ACT Yellow
This LED is wired to the Ethernet hardware.
– On indicates bad initialization
– Off indicates ready
– Blinking indicates network activity

Reset Button
The behavior of the reset button is user-defined. See “Reset Button” on page 16 and the NS520 BSP
Porting Guide for LED programming information.
Antenna
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 only fits on the
product one way 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..
Antenna Description
Type Desktop Dipole 30 cm
Antenna Extension Cord
Part number DC-ANT-24DT DC-ANT-24DP DC-ANT-E-24DP
Gain 1.8 dBi 2 dBi -.5dB
Caution: This Part 15 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
user’s authority to operate the device.
