2.3.1.5 Stacking Do’s And Don’ts
•
Do power off all counters (remove USB lead) before
connecting and disconnecting counters from the stack
•
Don’t remove any counters from the stack while the software
is running
•
Don’t remove any counters from the stack while any of them
are powered
•
Don’t stack several counters and leave one or more counters
un-stacked…this configuration will ignore the un-stacked
counters
•
Don’t short circuit any of the stack connector pins, or bend the
pins or use excessive force trying to mate the connectors
•
Don’t probe or drive any of the stack connector signals
•
Avoid touching the stack connector pins/signals during
stacking
•
Do make sure that each stack connector is properly seated in
place before trying to stack another channel on top
•
Don’t allow water or dirt etc to enter the counter via the stack
connector access hole
•
Do remember that counters in the stack
are NOT isolated
from each other, they are only isolated from the USB ports.
To re-iterate, stacked counters have their BNC connector
bodies connected together through the stack connector.
