Subject:Ventilator - Hosa FSC-385 footswitch

I ordered a Hosa FSC-385 to modify to work with the Ventilator. It came in today and I found that NO modifications are necessary. It can access all three speeds, the unit is built well, and is not expensive at all. I got mine at jr.com for $14.99 with free shipping.
You do have to use a TRS-TRS 1/4" cable with it.
