GPI-1501 General Purpose Interface I/O Module
GPI-1501 General Purpose Interface I/O Module
A GPI-1501 card supports 20 GPI inputs, and 8 configurable GPI input/output terminals. The
associated rear panel holds a DB-44 connector, through which all signal inputs and outputs
are routed.
The pinout of this connector is as follows:
DB-44 connector
For ease of connection, you may use the GPI-1501-TBA terminal block adapter with integral
44-pin connector. Refer to the GPI-1501 Guide to Installation and Operation (available from
the
Documentation Library
section of Grass Valley’s website), for more information. Refer to
the Kaleido-X User’s Manual for detailed instructions on configuring a GPI-1501 within your
multiviewer system.
