OK Then,
First of all, you'll want to be using the latest API Driver
www.usbuirt.com/latestAPIDriver.zipSimply unzip the uuirtdrv.dll file in this .zip and copy it overtop the one in your Windows\System32 folder.
Then you'll also want to make sure you're running the latest Girder plugin
www.usbuirt.com/latestGirderPlugin.zipAlso, you'll want to download and install the 'USB-UIRT-2' plugin:
www.usbuirt.com/latestGirderPlugin2.zip . With this second plugin, you'll see two USB-UIRT drivers listed in Girder. What this basically means is that you'll have to assign Girder actions to the appropriate plugin (regular USB-UIRT or USB-UIRT-2') depending on which USB-UIRT you want to transmit from.
Finally, you'll need to 'rename' one of your USB-UIRT's. To do this:
1. Plug in only ONE of your USB-UIRT's (the one you want to rename).
2. Shut down any applications using the USB-UIRT.
3. Download and run the rename utility:
www.usbuirt.com/uurename.zip4. When prompted to rename the device, choose 'Y'es
5. Rename the USB-UIRT to number '2'
At this point you can plug in both USB-UIRT's and enable both Plugins in Girder.
Let me know if you have any questions!
