I agree that Ethernet/TCP/IP would be a good choice to eventually-replace

RS-232 serial. Ethernet/TCP/IP is much more stable, extendable and reliable interface choice than is USB. USB has built-in obsolescence. The vast majority of USB devices are disposable junk and nobody cares if you have to buy a new $100 printer every couple of years. That is a completely different scenario than a $10-20,000 telescope mount. Computers and laptops these days are geared to the average consumer that no longer has an understanding or need to interface to serial devices. We high-tech astro-geeks are now a minority that has to deal with the limitations of mainstream products for our specialized applications. Personally, I would rather take a few steps to improve/upgrade the disposable, mainstream products so they will work with my premium astro gear, versus asking the makers of my premium astro-gear to turn their products into disposable objects.

Subject: RE: [ap-gto] Re: SERIAL PORTS (was: cannot connect gto CP3 to the SKy 6) Gerald, Apparently, there are quite a few other folks that don't have a problemwith USB. All of my other devices such as main camera, guider, and focuser all are USB. The only device I have anissue is the one developed over 50 years ago-the serial port on the AP mount.The problem is probably not the serial port. The problem is probably with the USB converter you are using. If so, that is a USB problem, not a serial port problem. IMO, USB is the wrong way to go. Ethernet would be a *much* better solution. -Ray Gralak Author of Astro-Physics Command Center (APCC) Author of PEMPro: http://www.ccdware.com Author of Astro-Physics V2 ASCOM Driver: http://www.gralak.com/apdriver Author of PulseGuide: http://www.pulseguide.com Author of Sigma: http://www.gralak.com/sigma
