GM862 problems with turning it on
PostPosted: Fri Jun 13, 2008 4:59 am     Reply with quote
Hi,

I try to use the GM862-Quad (datasheet is there http://www.roundsolutions.com/techdocs/index.htm). As the datasheet says I set the output of my uC to an high level, wait 2.5 seconds and then I set it to a low level. Now the GM862 should be on. But it doesn't work. After 5 seconds it shut down.
When I don't set the output low I have an high level on PWRMON but after 5 to 8 seconds this pin goes low for about 200ms and then release. The status LED is fast blinking which means net search, not registered or turning off (look at page 62 of the datasheet).
What could be the problem???
Thanks
