2.3 Using More Than One USBcount50

2.3.1 Stacked Mode

A unique feature of the USBcount50 architecture is that up to 4 devices3 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.

3Don’t stack more than 4, the software will reject this.
