Subject: Success!! Garmin USB GPS + ETX90-EC with #497 AutoStar (via PC) Sent: Tuesday, November 11, 2008 02:25:55 From: Rowland Walsingham (email@example.com) Thought I'd report my success in getting my Garmin eTrex Vista C USB GPS working with my old ETX90 scope. To do this I did the following: * Hooked up the ETX to a laptop via a Prolific USB/serial rs232 converter and appropriate cable (widely available as a kit from eBay, e.g. item number 320236994996 on ebay.com). * Leave ETX off at this point. * Installed StarPatch and patched my version (43Eg) using "Patch43GC.spf" (no license as yet, so trial limitations apply). * Downloaded "Redirect.exe" from http://www.stargps.ca/downloads.htm * Downloaded and installed trial version of Franson GPSgate from http://franson.com/gpsgate/download.asp * As I run Vista 64, I followed the additional instructions here: http://franson.com/forum/topic.asp?TOPIC_ID=8252 * A little basic configuration using the Franson GPSgate wizard! * Start up redirect and select relevant com ports (I used virtual COM5 for GPS and COM4 for ETX/AutoStar #497. * Hit the "Connect" button in redirect and watch the GPS output appear in the top half of the redirect window. * Power on the scope. * Watch as the USB GPS aquires a position. * As I am running trial version of StarGPS, coords etc are not saved - limitation of the trialware! * However, the coordinates and timezone are successfully and correctly shown on the AutoStar #497 handset for a few seconds before it tells you it's trialware and the coords etc will not be saved. So, for anyone wanting to do this, there is a way.........Just needs a laptop in the middle, but I use the laptop to run a stellarium telescope server from anyhow, so it's a possibility, if I can stump up the cash for the software licenses ;-) ATB, Rowland.
