13
inverts the route. Value 0 returns control to the menu item, thus returns
to either input A or input B.
Auto-GPI
only applies when used as backup-switch in
2x2
mode
(
Output-Config
setting). Assumed is that Input-A is the main
channel, Input-B is the backup. GPI contact 1 forces the Output-A to
Input-B, regardless of an error condition for this input.
Switch-Back
When
Input-Sel
is set to
Auto
, this menu item decides on whether
or not the input selection should switch back when the failed input is
back to OK status. Set to
On
the input will switch back immediate when
the failed input returned Ok.
Set to
Off
, the channels will not switch back after input recovers from
an error, even when input B (the backup) has an error. The switch stays
switched infinite, and is only reset if the configuration is changed
manually.
Can also be set to
BackUp_Fail
in which case the input will switch
back when input B (Backup) fails and the input A (Main) is Ok. This
mode avoids the immediate switch-back of the
Switch-Back
On
mode, until it really has to switch back to the Ok main channel. Default
is
Off
. See appendix 1 for the exact switch behavior.
GPI-Ctrl
(Software versions
before 0709)
GPI-Ctrl
can be set to
Mode-1_Latching
,
Mode-1_Non-
Latch
or
Mode-2
. Non-Latching when a contact is closed all the
time
Latching
when a contact is closed momentarily.
Mode-2
works
with GPI pulses, tapping GPI1 will select input 1, tapping GPI2 will
select input 2. The default setting of
GPI_Mode
is
Mode-1_Non-
Latch
.
Inp_SelA
Here you select which of the four SDI inputs will be used for the
channel A probe (before the automatic backup switch function). Choices
are
SDI-1
,
SDI-2
,
SDI-3,SDI-4
or
GPI-C
(only in software
versions from 0709). Default is
SDI-1
.
Inp_SelB
Here you select which of the four SDI inputs will be used for the
channel B probe (before the automatic backup switch function). Choices
are
SDI-1
,
SDI-2
,
SDI-3,SDI-4
or
GPI-D
(only in software
versions from 0709). Default is
SDI-2
.
Output_mux
When
Output-Config
is set to
2+2
, both main output A and the
backup B are output. When set to
4
the main output A is routed to all
four outputs. This output multiplexer is located after the backup switch
function.
