Re: Why can't I get a good connection with my pendants?

[Guest guest]

Listmates,Here is an update: I have now solved the problem of the pendant saying " Connecting... " but never Connecting. It was a Com Port problem. I didn't realize it, because in the past when I've had this problem it says " No Port. " But this time somehow there was a port, but it didn't coincide with where the pendant was supposed to be (i.e., the port named in " Device Manager. " ). OK, so that's solved, but I still can't solve the problem that, most of the time, Channel 1 is on continuous red regardless of which pendant, which receiver, which laptop, which electrodes, etc.  Any help appreciated. It's so frustrating that I can't find anybody in or near New York City to look at these pendants.

My electrodes are covered with felt pads I made myself to hold the saline. Earclips are also covered in felt pads and soaked in saline. The scalp is prepped with alcohol and NuPrep.

What could be wrong?? could it be a problem with my copy of BioExplorer? Oh -- I should say that sometimes the connection is FINE and I get beautiful EEG -- but it is completely unpredictable! and now it feels like acting up. Very frustrating!

Liz,

When I first received my pendant I also had a similar problem with Ch 1. After

speaking with Pete, I found out it may be a problem with some pocket pendants.

I spoke with Bruce from Pocket Neurobics and he had it repaired within a week.

I think it was a solder joint issue.. Does Channel 2 seem to work ok? Are you

getting a good signal from Ch2?

I thought I was going crazy when I encountered the problem, I thought I wasn't

doing something right..

Liz,The problem with Connecting is probably related to your changing th Dongle (receiver).RIGHT-click on My Computer and choose Manage, in the window that opens, in the left pane, select Device Manager.

In the Center pane, on the list of Devices that appears, click PortsYou should see the Wireless Dongle and the COM port where it can be addressed.Make sure that BE has the Pendant set to receive info from that same COM port.

If that doesn't work, verify that the Pendant and dongle are both blinking the same number of times.Pete-- Van Deusenpvdtlc@...
