Using BHX17b
When using the backpanel with bypass relay (BHX17b), you must
first set the
bottom-side
dip-switch
on the card
to ‘on’. This will
pass 5 volt to the backpanel. If this is not done, the relays won’t work
at all.
On the BHX17b itself there are also 2 dipswitches (see picture on the
next page). The bottom dipswitch is not connected. With the top
switch you can choose the Bypass function. There are 2 possible
function indications “on” (printed on the dip switch itself) and “off”:
“
Direct Backpanel Switchover
” dipswitch set to
ON
:
Will make the BHX-backpanel switch over to the processed signal as
soon as it detects the trigger signal from the connected synapse card.
This setting will minimize the bypass time and ensures fast recovery
of processed signals.
The
ON
setting is recommended if the BHX-backpanel is used in
combination with synapse cards:
which have a short initialization time, or
which have a delayed trigger-signal onboard.
“
Direct Backpanel Switchover
” dipswitch set to
OFF
(default)
:
Will make the BHX-backpanel switch after about 15 seconds from
the moment the BHX-backpanel detects the trigger signal from the
connected synapse card. This setting will allow more time for
complex synapse cards to finish initialization and stabilize proper
signal processing before the backpanel switches over to the processed
signal.
The
OFF
setting is recommended if the BHX-backpanel is used in
combination with synapse cards:
which are more complex and thus need longer initialization
time and do NOT have a delayed trigger-signal onboard.
