1–2 • Introduction GPI-100 User Manual (Iss. 03)
Overview
The GPI-100 enables GPIO triggers to be carried in the Vertical Ancillary (VANC) data area of an
SDI (SMPTE 259) or HD-SDI (SMPTE 292) video signal, in accordance with SMPTE 291 and
other related standards. The GPI-100, as an encoder, reads GPIO inputs and inserts them into the
VANC. As a decoder, it reads the VANC and applies the data to GPIO outputs. This allows GPIO
enabled equipment to be triggered remotely through the video path.
The GPI-100 provides a simple interface allowing the carriage of GPIO triggers as part of the
video signal. For example:
• The card is set to act as an encoder or a decoder. This determines if the card will read and
place the GPIOs into the VANC (encode) or read the VANC and assert the GPIOs
(decode).
• GPIO triggers are logged both to the screen and to a log file. The log file can be
transferred from the card to a PC through a network connection.
• Entries in the log file are time stamped. The GPI-100 can be set to use an NTP time
server, time code or its own internal clock as its time reference.
• One GPI-100 can insert trigger for many GPI-100s acting as receivers. There are eight
GPIOs available and a receiver can act on all or some of them.
• Card configuration can be uploaded to a PC. This configuration can be used to
reconfigure a card back to a known state or to quickly clone the card setup into other
cards.
Features
The following features make the GPI-100 the best solution for carrying GPIO triggers with the
video:
• Operates automatically with popular SD and HD video formats
• Each card can be set up to either encode or decode
• Frame-accurate triggering: each trigger is delivered within one video frame time
• All triggers are logged as proof of delivery
• Allows you to select a unique Originator ID so another operator’s triggers will not affect
your GPIO outputs
• Video bypass capability
• Reports status and can be configured remotely via the DashBoard Control System™
• Fits openGear DFR-8300 series frames
• 5-year transferable warranty
