OPERATION
3.13. CONFIGURING THE GENERAL PURPOSE OUTPUTS (GPO)
The X0401 series routers have four general purpose (GPO) outputs that can be programmed to various
functions to suit the specific requirements of the user. The
GPO SETUP
menus are used to configure the
functions of the GPO outputs. See section 2.5 for information about connecting the GPO outputs. The
chart below shows the items available in the
GPO SETUP
menu. Sections 3.13.1 to 3.13.5 provide
detailed information about each of the sub-menus.
Disable All GPOs
This menu allows the user to manually override the programmed functions of
all GPO outputs and disable them.
Enable All GPOs
This menu allows the user to enable all GPO outputs and return them to their
programmed functions.
Gpo Encoding
This menu allows the user to choose one of two pre-defined encoding modes
for the GPO outputs.
GPO Type
This menu allows the user to select whether the GPO output will be latched
or momentary.
Program GPOs
This menu allows the user to program different functions for the GPO
outputs.
3.13.1. Temporarily Disabling the GPO Functions
GPO SETUP
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.
Disable all GPOs
3.13.2. Re-enabling the GPO Functions
GPO SETUP
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.
Enable all GPOs
3.13.3. Configuring the Encoding Mode for the GPO Outputs
GPO SETUP
The GPOs can be configured to operate in an encoded mode. In this mode,
the GPO outputs are pre-assigned to provide encoded tallies of the router
input selections for the V1 buss. 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.
GPO Encoding
none
hex V1
3.13.3.1. HEX GPO Encoding
The
HEX V1
GPO encoding mode is designed to allow the four GPO outputs to give tallies for the V1
buss. The four General purpose outputs are encoded to provide tallies to indicate which one of the 4
inputs is currently routed to the video buss as shown in Table 3-8. The encoded tally is held low while the
respective video input is routed to the video output buss.
