2.3.1.3 USB Connections For Stacked Configurations
All stacked counters need a USB connection. A standard hub may be useful for
Each counter needs about 200mA. Plugging more than 2 counters into a hub will mean that the hub may need to be powered externally. Please refer to the hub’s documentation for more details about the power available per port.
2.3.1.4 Software For Stacked Configurations
When you run USBcount50, it will automatically detect the counters connected via USB and will also check to see if the counters are electrically connected together via the stack. It will then initialise all connected counters, one at a time. This may take a few seconds.
If you stack several counters but forget to connect say one of the counters to a USB port, the software will warn you and will not run.
The software will display a channel diagram for each counter in use.
The channel number allocated to each counter depends on its serial number, so the order you stacked them will almost certainly NOT be the same as the channel order allocated by software.
To find out which counter is Channel 1, use the CH1 tab and click the “id” button.
The LED on that counter will blink rapidly for about 4 seconds, or until you click the button again.
Repeat this for each channel in the stack to identify them.
If you like, you can stop the software, and unplug all the counters from their USB connections, and then
