It's not expecting any handshaking at all. The BT unit you're trying to use says that it uses TTL levels, so you should take the MAX232 out of the circuit and connect directly to the PIC chip.

I am trying to make the following BT adapter work, see: http://stores.ebay.com/emall-foryou The BT adapter does not appear to be communicating with the DSC board. Will the max232 work with only TX RX signals or is other handshaking required that this BT adapter does not provide. Appricate any input, thanks Mark Dave,

It's worth pointing out that this device costs about twice what it would cost to pick up a USB-serial converter. Also, I think using this would make it harder to use bluetooth if you ever decided to go that way. You can easily purchase a bluetooth-serial adapter to plug right into the serial connector on the board, but you couldn't do the same thing with a USB-bluetooth converter on the board (that converter will only work with a PC). This is the reason I've stuck with the serial interface on my board--it's much easier to adapt to either USB or bluetooth. Once you modify the board by swapping out the serial for something else, you're pretty-much stuck with whatever you swapped it for. If you try this out, let me know how it works.

I was wondering if this USB-DB9 replacement would cause any problems? http://www.copelandcommunications.com/Socket%20USB232.aspx It looks like a direct replacement and the tech specs look like it will communicate with the MAX232. Your thoughts? Dave, getting ready to purchase from Far Circuits. I was wondering if this USB-DB9 replacement would cause any problems?

There is no feature at this time to save the alignment for future use. I assume you have a permanently-mounted telescope? Dave Bent,

If I leave the unit on for more than 17 hours it will loose its alignment. Is there any time limit for keeping an alignment with your system if I leave it on and connected to a PC? Thanks, Josh I currently have a Sky Commander hooked to my GEM mount. If I leave the unit on for more than 17 hours it will loose its alignment. Is there any time limit for keeping an alignment with your system if I leave it on and connected to a PC?
