USB-IR dongle updated

The USB-IR infrared dongle is now available and is supplied with a transparent case. The lid covering the USB connector unclips and clips onto the back. A wrist strap can be attached to the Bud case.

USB infrared adaptors now sell for a few dollars but most are designed to communicate to computers using a software driven IrDA stack, and cannot send out SIR (simple Infrared) data at 9600 baud. Many instruments such as the Welch Allyn Spot Medical Instrument series use SIR to communicate and the default baud rate is 9600. The Baud rate can be adjusted up to 115200 baud using an internal dipswitch.
