Hi,
Does anybody have any information regarding a LF501 spirometer made by Marquette? It connects to a PC and has 3 connections:- 9 pin serial, ps2 male & ps2 femail. I have tried many ways of communicating with the unit using the GE Cardiosoft software but cannot even get the power LED to light on the unit. Is anybody familiar with this product?
All help appreciated, cheers,
John
