siginstat
This query-only command shows the current status of both Signal Inputs A and B. The first character
is for Signal Input A and the second character is for Signal Input B. A ‘0’ means a signal is not pres-
ent and a ‘1’ means a signal is present.
Query:
siginstat
Chassis response:
10
(Signal Input A is present. Signal Input B is not.)
sigoutstat
This query-only command shows the current status of Output Signals 1 though 10. The first charac-
ter is for Output 1, the second is for Output 2, and so on. A ‘0’ means there is no input signal, the out-
put driver is bad or a short is connected to it. A one ‘1’ means there is an input signal and the output
signal is good.
Query:
sigoutstat
Chassis response:
1011111111
(A problem exists at Output 2.)
status
This command displays the results of all status query commands.
Query:
status
Chassis response:
alarm = 00000x 0000000000 000x
disablestat = 00
pwrstat = 10
selectedin = A
siginstat = 11
sigoutstat = 1111111111
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.)
Query:
switchmode
Chassis response:
ba
Factory default setting:
ab
