AT-Auto Serial Connection Problems
|
John Huffman
We are mounting an AT-Auto in a cabinet at the 125' level of a cell tower.?
 Testing, before it gets hauled up, shows that the serial connection is intermittent at best and not connect much of the time.? We are using the Java version on a Windows 10 machine. The AT-Auto cabinet has an Ethernet switch and an Ethernet to serial converter.? The AT-Auto¡¯s serial port is connected to the Ethernet serial converter and it appears to work as we can see serial traffic in and out of the converter.? ?The serial port is an Eltima Virtual Serial Port (COM 26).? It shows up on the pick list in HRI.
?
In HRI the Edit >Settings > AT-Auto shows "Palstar AT-Auto is present" box checked,? "Use CI-V interface" box not checked.? "Use RS232 interface" box is checked.? Tuner CI-V address is E0.? Palstar Firmware is 2.11.? COM 26 and 9600 are selected.? On the tuner ICOM no ext tuner is selected as Is baud 9600.
?
We need a reliable link.? Any suggestions?

Very impressive. I seem to recall that RTS causes the AT AUTO to do a reset. I'd need to look it up in the manual. If my memory is correct, then you'd need a modified serial cable with the RTS wire cut, or some way to make the Ethernet adapter stop using RTS. Check the manual. I don't know why you are using the java version with windows 10. Nothing wrong with that. I just thought the visual studios version looks better and performs a little faster.

Howard - In the past, the Visual Studio version was giving me a problem installing.? I didn't try on this particular Windows 10 computer.? Where can I find the install file? We will try stopping the RTS or cutting the line and get back to you. Thanks for the great support! 73 de K1ESE John On Wed, Sep 26, 2018 at 8:18 AM Howard Z <HowardZ@...> wrote:

¿ªÔÆÌåÓýJohn,
Read the Kessler Engineering manual for the AT AUTO. In Chapter 9 it talks about the RTS line doing a reset - and that doing this constantly can damage the tuner. It talks about a jumper inside the AT AUTO to disable the RTS reset line. So, there should be no need to "cut" the RTS line - just move the appropriate jumper. Read the manual and you should find details. All version should be in the FILES section at the groups.io website. As I said, there should be no problem using the Java version of HRI on Windows 10. I just thought people preferred the Visual Studios version of HRI. Good Luck, Howard On 9/26/2018 08:44, John Huffman wrote:
