GENERAL PURPOSE INPUTS & OUTPUTS
Overview
Standard System
The switcher mainframe has eight general purpose inputs and
32 outputs. The action of each of these inputs and outputs
may be allocated by the user from a range of functions. The
allocation is performed in the GPI and GPO menus.
Quad DSK (option)
Where a Quad DSK unit is fitted a further eight general
purpose inputs are available, the functions of which may also
be determined by the user.
Note
There are eight fixed Tally outputs available on the Quad DSK.
The Inputs
The general purpose inputs, eight or sixteen, are user
programmable in the “Configure - User - GPI” menu.
(Systems without the Quad DSK option have eight inputs and
systems with Quad DSK have sixteen inputs).
Each input may be independently set to trigger a function
when an edge or level is applied to the input connector pin.
The available functions depend on the type of control panel
being used and whether the Quad DSK option is fitted.
The GPI menus and avalable GPI functions, with Quad DSK
(right) and without are shown below.
There are twelve functions applicable to the external quad
DSK unit as depicted in the right hand menu above.
Note
The first eight inputs are on the GPI & Tally connector (25 way
D-type) on the rear of the mainframe. The second eight are
on the GPI & Tally connector (25 way D-type) on the rear of
the Quad DSK unit.
