Sent: Friday, July 23, 2004 10:36:17 From: Justin (firstname.lastname@example.org) I just wanted to shoot you a quick email that may be considered useful to others. Yesterday I got the uncontrollable urge to control my ETX from my laptop. Couldn't wait for a cable to be shipped, so I gathered up the materials, and bought the rest from Radio Shack. After some cutting, stripping and soldering I made the cable described here: http://www.weasner.com/etx/autostar/as_cable505.html Unfortunately, I hadn't educated myself enough. I then realized that the cable didn't fit into any of the ports on the base of the scope Aux, or HBX. Little did I know it wasn't supposed to. Instead, I saw that the aux ports on the scope needed the phone hand set end. I promptly pillaged an old phone and re-soldered the new end on the cable I had made. I then plugged the cable into the laptop, and into the AUX port on the scope base DUMB MOVE. So then I see the power led light up faintly, with the power switch still in the off position on the scope base. Not sure why, but I then decided that was ok, and turned on the power to the scope base. Seconds later I heard a dreaded 'POP' coming from the back of my laptop. I've heard that sound enough times to know that I had just fried my serial port on my laptop. I packed everything up after deciding I didn't know what I had done wrong, and not wanting to cause further problems. Today I have been looking for clues as to where I messed up. I came across the most helpful picture, that could have saved my serial port. http://www.meade.com/catalog/autostar/images/auto_pc.gifMike here: Good ole Murphy again! Yes, a 25-pin to 9-pin adapter should be OK as long as it is wired correctly...
Maybe you want to add that pic to any articles describing the homemade cables? Maybe not, but I figured, it could have saved my serial port if I had seen that earlier. I know it's my fault anyways for jumping headlong into it assuming I knew what I was doing. Thankfully I have another serial port with a 25 pin out. Any idea if that will work with a 25pin to 9 pin adapter between the pc and the 505? Best regards, Justin Jerzak
