DASDEC-III
Quick Start Guide
Overview
There are two ways to receive a radio signal for the DASDEC-III to decode EAS alerts.
1. Internal radios connect to your site's antenna via a coaxial connection.
2. External radios that pass on audio to the DASDEC-III via a line-in-jack.
There are a total of four wiring options available. You can use a line-in-jack connection with external radios
using the 3.5mm jack and the additional sound card with its 3.5mm jack. You can also use the three radio
tuners radio 1,2, and 3 with the 4
The line-in-jack option uses a monoaural connection meaning that one 1/8 mini plug will need to be wired to
provide the audio of two sources provided from your external radios. Below is an image displaying what that
would look like broken down. The tip is left input, the ring is right input, and the sleeve is common ground.
Line-in-jack will utilize the blue 3.5 mm jack for main input 1 & 2 and if applicable the blue 3.5 mm jack on the
sound card or aux input 3 & 4.
