I have been running my EM-406A for about three hours now and it refuses to get a fix. The LED remains solid red. The data output works perfectly and confirms there is no fix. I have moved the board outside, down the street, across the street.... and no fix, just a solid red light! This is extremely frustrating. I was planning to use this on Sunday!
Using the SiRFDemo I get errors including Target SW: Unknown. If I try to switch to SiRF protocol, I get Comm: CE_BREAK repeated endlessly in the error window, and the baud rate tries to move to 38K. If I try to synchronize, I get a warning that the SetupComm() failed.
berni posting on Feb. 16 '07 and RancidWannaRiot posting on Aug. 10 '06 seem to have had the same problem. It is not clear they found a solution.
Did I mention how frustrating this is? Is this thing broken? I would appreciate any support.
