2.3 Using More Than One USBcount50
2.3.1 Stacked Mode
A unique feature of the USBcount50 architecture is that up to 4
devices
3 can be stacked to make a multi-channel instrument.
In order to use a stacked configuration, you must purchase the
stacking connector kit. This kit comprises 3 long lead connectors
and 1 short lead connector as shown:
2.3.1.1 Assembling The Stack
To stack the USBcount50 devices, first be sure that none of them are
connected to a USB port.
Before you begin, put the short lead connector to one-side…you’ll
use that one last.
Now, insert one of the long connectors from the top of one of the
counters (it doesn’t really matter which one). Push the pins of the
connector into the top of the stacking connector from the side where
you can see the top of the black connector down inside the counter.
Be careful when doing this, don’t use too much force or you may
damage the connector pins. Push the long connector all the way in
until it seats down on the counter’s internal connector. You should
be able to see the gold pins about 2-3mm beyond the bottom surface
of the counter. The connectors have no pin orientation…they can go
in 2 possible ways round…both are OK.
3 Don’t stack more than 4, the software will reject this.
