RE:Geek toy (modified 0 times) redwood Profile since you brought up a serial devise... would anybody like to provide a nice, Detailed account on adding the serial port... I have all my stuff, chips, resistors.. I tried to bring one thread to the top, but got no responses.. using the 'Perfect' mod ... I think I'm _close to understanding.. just don't wanna Ruin anything.. Thanks! 09-16-2001 07:58:08

RE:Geek toy (modified 0 times) Perplexer Profile I've been using a serial -> infared receiver like the IRMan for about a year. It is currently in use for in-car I-Opener control, and it is very very cool... I rarely have to pull out the keyboard or mouse for normal operation. I am using a remote control for Winamp control and visualization. I also use the remote with StreetFinder Deluxe to start/stop the GPS, scroll the map, zoom in and out. I can shut down windows with two keypresses on the remote. IRAssistant is powerful IR control software, check it out at http://www.antenet.fi/irassistant/ 09-17-2001 00:08:13

RE:Geek toy (modified 0 times) *SF* Profile Redwood asked > regarding Perfect's serial port.. does VCC, on CN12, hook to the VCC on the MAX chip? My Short Answer is Yes. But I don't know what MAX chip you have or anything about your 3 volt GPS. So for You to Answer Your own Question, Find the Data Sheet for your MAX chip & see if VCC is listed as 5 VDC 09-17-2001 00:39:17

RE:Geek toy (modified 0 times) redwood Profile thanks SF, I have a Garmin eTrex gps... which I will either power, from, batteries, or, a 12volt/adpt ... so, That I understand... its the com port on the io etc... MY gps doesn't get Any power from the com port.. but...it Does use the signals... now, Does the chip Need power?? or... do the signals run thru? btw, I have a few different chips to use.. via samples, thank you...

RE:Geek toy (modified 0 times) redwood Profile hi SF ok, my garmin etrex gps ... only uses TX and RX ... http://home.cdsnet.net/~purple/projects/g45contr/ePlug/assembly.jpg shows the connections... since I get power, Elsewere... the question IS.. do I Need to power VCC on CN12 .. in order to send power to my MAX chip? or, do the two lines I need, Work, running thru this chip without any power ? ( sorry, Clueless here..) now, I would Love, to hookup all the lines necessary for a 'normal' com port.. (to use an IR remote... ) but, for Now, I'm willing to just get my GPS going.. I guess, I just Don't understand, why, in Perfect's drawing... there Isn't a line connecting VCC ... all the connected lines make sense to me, (well, mostly, :) ) thanks! 09-18-2001 07:03:17

RE:Geek toy (modified 0 times) *SF* Profile redwood, You are Scaring Me ! (but, I haven't fully understood everything I have done either) Anyhow, Lines aren't drawn for grounds or supplies, to keep the drawing clean & easy to read. The Max chip is an Active Component & must be Powered. You have Not read it's Datasheet. From http://www.Dictionary.com to http://www.acronymfinder.com VCC = Voltage at the Common Collector (positive [+] electrical connection) 09-18-2001 09:30:35
