I hope this is an acceptable location for this post. Does anyone have any experience trouble shooting or access to a help file for the Tel-X-Driver and TEL-218DRV equipment? I have included a copy of my correspondence with the company explaining the situation below. 1. The problem statement, all variables and given/known data My lab group was assigned a project in our 300 level physics electronics lab. We are receiving an error message during set up. The help file is not included on the software disc that came with the equipment. I tried contacting the company. They responded once and then didn't reply again.
