Setting up GPI/O
32 DB6 Single / Multi / AES – Firmware version 1.30
GP Input Calibration
To calibrate GPI, go to the Frame / Sys-
tem / GPI/O / Cal page.
DB6 GPI calibration page
Each GPI may be used to switch between up to
8 states. GPI calibration should be performed
when switching between more than two states
(as it is required for preset recall).
Current section
The Current section of the GPI Calibration page
provides live status information for the GP in-
puts. Here, “Vs” denotes positive terminal on the
respective GP connector, typically 3.3 V.
Limits section
The Limits section of the GPI Calibration page
shows the lower (“GPI Lo Threshold”) and upper
(“GPI Hi Threshold”) limits of the voltage win-
dows for the four GP inputs.
To calibrate a GPI input, click the respective Cali-
brate button and follow the on-screen instruc-
tions.
Setting up GPO
To set up GPO, go to the Frame / Sys-
tem / GPI/O / GPO page.
DB6 GPO page
Two relay-based general-purpose outputs are
available. Use this page to configure them.
GPO 1 and GPO 2 parameters
Use the GPO 1 and GPO 2 parameters to spec-
ify which status information should be transmit-
ted to the GPO pins. Available settings are “Off”,
“Sync LED”, “Alert LED” and “Signal LED”. If you
select one of the three LED options, the selected
GPO pin pair will communicate the status of the
respective DB6 front panel LED.
Idle State 1 and Idle State 2 parameters
Use the Idle State 1 and Idle State 2 parameters
to specify which state of the respective GPO re-
lay (1 or 2) should represent the
inactive state of
the assigned LED/status information. Available
settings are “Open” and “Closed”.
GPO setup example
– To signal DB6 Synchronization Status on GPO
relay 1 – see “Sync LED(s) – SDI” on page
12 –, set the GPO 1 parameter to “Sync
LED”.
– If you set Idle State 1 to “Open”, the GPO 1
relay…
– will be open as long as no synchronization
has been achieved and
– will close when synchronization has been
achieved.
