The phone jack should be output from an internal modem, ie modulated 56 kbs tones, AFAIK. LX200 uses RS-232 standards, ie voltages. My laptop has the same "deficiency", but there are cheap USB-RS232C converters available in electronics/hobbyists stores (~$30 in Sweden). These are usually on short cables. I haven't seen one for the PC card slot, and those are being phased out for a new (similar, improved) standard. There is one more project: finding the correct cable! I did not get one from a shop, and anyway Meade info hints that you also need a null modem in the connection! So I compared available cable specs on the web, and chose the one which most clearly described it, and contained no evidence that also null modem was required. I found http://obs.nineplanets.org/meade/cable.html I used an ordinary modem cable to fit the converter, and a long telephone cable (RJ-11?) with four (coloured) wires. I cut them near one end, and connected the wires, carefully checking with an ohmmeter that I picked the right ones. /Björn ----- Original Message ----- From: "Derek C Breit" Subject: RE: Telescope Control Software for Satellite That worked perfectly.. Thanks.. It has just dawned on me that I have never used this laptop to control my LX200 and that it does not have a serial port.. Maybe the empty Network "phone jack" will work directly with the RS-232 port??? Or something that slides into the laptop card slot?? Seems I have just found my next project.. Like I did not have enough of those!

SatTrack will remember the directory AND the file name to next run. I had a similar problem, but didn't investigate it, since I find manual download from SpaceTrack easy enough. ----- Original Message ----- Hmmmm.. I cannot get Satellite tracker to download the TLE's.. Can I copy the elements from the Heavensat directory, which downloads them fine??? ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html ------------------------------------------------------------------------- Subscribe/Unsubscribe info, Frequently Asked Questions, SeeSat-L archive: http://www.satobs.org/seesat/seesatindex.html
