switchmode
This command sets the switching mode in case a fault is detected. A fault is either lack of sig-
nal presence or a logic high level on Disable A or Disable B, provided these have been config-
ured properly (see
disablemode
). Syntax is:
switchmode=x
, where
x
is A, B, AB, or BA. If
switchmode=ab
then the chassis will use Signal Input A as its primary source and Signal Input B
as its secondary source. This means the chassis will switch to Signal Input B if a problem on A oc-
curs. If
switchmode=ba
then the reverse is true. If
switchmode=a
or
switchmode=b
then there
is no secondary input. The chassis will either remain on the primary signal input or will switch it off,
depending on the
disablemode
setting. Typing
switchmode
with no parameter will display the
current
switchmode
setting.
If you change this setting it will be saved in non-volatile memory. This is a configuration command
and if the parameters are changed this will cause a re-initialization of the software.
Set:
switchmode=ba
Chassis response:
OK
(B is primary. A secondary.)

upload
This command allows you to upgrade the distribution chassis software. See Appendix B - Upgrading
the Firmware for more information.
