4.11 Setup > GPIO: Setup General Purpose IO Options
The Setup GPIO page displays the state of the General Purpose Inputs and Outputs (GPIO) and allows programming.
GPIO is provided by connectors on the back panel of the DASDEC II. The state of the Front Panel button is included in
the GPIO table display. The state of the Internal Balanced Audio output is also displayed in the table.
Changes made to the GPIO actions/relay associations are immediate. The page updates instantly.
Auto-Refresh Timer: With the DASDEC II Plus Package license displays an Auto-Refresh Timer selector. This allows
the page to be re-displayed every 15, 30, or 60 seconds. This feature can be used to automatically view updates the
GPIO status.
There are two - or three - sections on the page to review and/or configure: DASDEC II Server GPIO Table; Programmable
GPIO; and Network GPIO Table.
1. DASDEC II Server GPIO Table
The top section of this page displays the current status of the built-in DASDEC II GPIO hardware. The top
row displays the status of the inputs. The first input is the state of the Front Panel button. This is not
available as a GPIO input but uses the internal GPIO circuitry. The next two columns show the programmed
actions and current closure state for GPIO inputs 1 and 2. The second row displays the status of the relay
outputs and of the internal audio/pass-through relay. The first two columns show the programmed triggers
and current closure state for GPIO outputs 1 and 2.
Two buttons are placed under the table for testing GPIO output relays. The first button, Close EAS Audio
Relay sends out a command to close all relays that are programmed to EAS audio. The companion button,
Open EAS Audio Relay, sends the command to open all relays that are programmed to EAS audio.
2. Programmable GPIO Input/output Actions
Programmable options are GPIO Input 1 and 2 and GPIO Output 1 (Broadcast only) and 2 Relay. The GPIO
Output #1 relay is programmable if the broadcast option is licensed. Otherwise, it is tied to EAS broadcast
audio output and only closes during the play-out of EAS audio. It is timed such that if the video details page
is displayed by the DASDEC II, the video will be synced at the time the relay closes.
Multistation mode note: When DASDEC II multistation mode is enabled, the used physical GPIO outputs
are selectable for each station. Thus, a station can choose to NOT use a GPIO output. The station
assignment options do not allow reprogramming of a relay, just its inclusion. This allows specific GPIO
