I have four KVH DSP-3000 fiber optic gyroscopes. Serial, 1000HZ, asynchronous. Decided the DSP-5000's were more what I was looking for. Three of them are new and sealed in their original boxes, one has been opened for a test fit, and its still sealed in its anti-static bag. Here's the link to the technical manual: http://www.earthtech.org/experiments...40215C_Web.pdf,
pages 7 to 11. The KVH site requires a sign up to view the same .pdf. Can send pictures if requested. Please contact here or e-mail if you have any questions/comments/offers.
