Subject: Hello. Sent: Friday, January 9, 2009 20:41:51 From: jameswr@ellijay.com (jameswr@ellijay.com) I was wondering if you could help me. I searched your site and couldnt find the exact infor mation so Im sending you this email. I have a Meade ETX-70AT and a 506 cable with a missing RJ-11 to DB-9 adapter. I have a USB to serial adapter now and I want to wire it directly to the wires that the RJ-11 is attached to. Would you happen to know on the RJ-11 connector, which pins are RXD, TXD and GROUND? Thanks in advance and forgive me if I missed the proper post.Mike here: First, please read the Email Etiquette on the ETX Site Home Page; your message was originally rejected and deleted UNREAD as SPAM due to the ambiguous subject line. Thanks for understanding. Second, please see the Announcements: Email Change Notice for important information. As to cable tip connections, see the Helpful Information: AutoStar Info page for #505 serial cable info. It will be the same for the connector for the #506. Right Dick (our AutoStar expert)?
From: richard seymour (rseymour@wolfenet.com) Good question... it's an item that i've never seen documented, either. So i just took an ohmmeter to my 506's DB9-to-RJ11 adapter. It turns out it's wired the same way as the DB9-to-RJ11 adapter that's part of Mede's 505 cable set (for the 497 Autostar) and which comes with their LPI and DSI cameras. The pin numbers i am going to use for the RJ11 end are based upon looking into the open socket (where the RJ plug will go), with the locking tang "down" and the pin on the left called "1". DB9 pin two connects to RJ11 pin 3 (data from PC) DB9 pin three connects to RJ11 pin 2 (data to PC) DB9 pin five connects to RJ11 pin 5 (ground) have fun --dick
