3.13.1. How to Override (Temporarily Disable) the GPO Functions
GPO SETUP
Disable all Gpo’s
Pressing the SELECT key when this menu item is shown will override the
programmed functions of all the GPO outputs. The GPO outputs will be Off
when they are disabled.
3.13.2. How to turn off the GPO Override (Return the GPOs to their Programmed Functions)
GPO SETUP
Enable all Gpo’s
Pressing the SELECT key when this menu item is shown will restore the
programmed functions of all the GPO outputs. Individual GPOs can be
disabled using the Program Gpo’s menu item (see section 3.13.5).
3.13.3. Configuring the Encoding mode for the GPO Outputs
GPO SETUP
Gpo Encoding
gpo enc:none
gpo enc:hex v1
gpo enc:hex v2
The GPOs can be configured to operate in one of 2 Encoded modes. In
these modes, the GPO outputs are pre-assigned to provide encoded tallies
of the router input selections for the V1 or V2 busses. Section 3.13.3.1
describes how the GPO encoding modes work.
When the GPO Encoding is set to none, all 4 outputs are available for the
user to assign to particular functions. Section 3.13.5 describes how to
program the individual GPO functions
3.13.3.1. HEX GPO Encoding
The HEX V1 and HEX V2 GPO encoding modes are designed to allow the four GPO outputs to give tallies
for either the V1 or V2 busses respectively. The four General purpose outputs are encoded to provide
tallies to indicate which one of the 12 inputs is currently routed to the video buss as shown in Table 3-6.
The encoded tally is held low while the respective video input is routed to the video output buss.
