Well, I did manage to get Biopac on the phone. First off, I must say they have some of the best customer service I’ve experienced. Definitely recommend calling them if you have any issues with any of their products.
Quick note on how my computers were set up. I had my acquisition computer connected to the MP35 unit via USB, and my presentation computer connect to the MP35 via I/O connector.
Anyhow, what I discovered I was doing wrong was in the channel setup (under MP35 menu), I was checking the boxes next to the analog input channels, but did not turn on any of the digital input channels. The options are from 1-8, but I found out I only needed to use D1. Unless you want to record the trigger spikes, you only need to check the first box for the trigger to work.
After that was set up, I went to the trigger options (also under the MP35 menu). There I clicked on the pull down menu and selected D1 for my trigger. I just kept default positive edge selected.
Then on the presentation computer, I used Superlab’s digital output option (as a new event) and selected all the channels available (0-7 I believe). I kept the pulse options as the default.
Strangely, I still had the problem with Superlab not triggering the BSL. What I did was to start the software that came with the Measurement Computing PCI-DIO24 I/O card, called InstaCal. From that software I was able to run tests on the I/O card. I noticed that running the tests would cause the BSL to receive a pulse. After that, I closed InstaCal and went back to my Superlab program and it then was able to send pusles at BSL. My best guess would be that after installing the drivers for the I/O card, you need to run the software and run the tests to “activate” the connections.
Anyways, now Superlab and BSL are happily working in harmony, which is nice because now I don’t have to sit there and manually start/stop my EMG acquisition.
Hope this helps
