in case anyone is interested...Actually the coupler does communicate with the GX007 but only optionally. The serial control simply loops through from the coupler to the GX unit and right to a serial terminal (my understanding from various docs I have gathered on the subject). The TX/RX lines just loop directly in and then back out of the GX to the DB25 serial port. I agree, however, that the length could easily exceed the specs for RS232. In fact I had expected this system to use some differential signalling like RS422/485 and was surprised that it did not seem to. The serial communication is actually optional. There are about 26 lines (4 power, 3 serial comm and about 19 others) used to either configure or report status. Personally I would prefer to use the serial control to avoid running 26 lines from the shack to the antenna site. Ultimately, this coupler only needs 26VDC @ 6A and nothing else. It will work totally automatically (when set to work that way). But it is nice to get temperature and other details from the status messages. http://w2hx.com/x/RohdeSchwarz/ebay%20pix/s-l500%20(7).jpg ________________________________________ From: cctalk <cctalk-bounces at classiccmp.org> on behalf of Bill Gunshannon via cctalk <cctalk at classiccmp.org> Sent: Friday, August 10, 2018 3:25 PM To: General Discussion: On-Topic and Off-Topic Posts Subject: Re: German Translation, Serial Port?

OK, Having read the manual on the antenna tuner and done some research I have found that there is a box that connects to the tuner and and a terminal. My guess is that "Asynchron 16" refers to some proprietary hardware/communications protocol used between the antenna tuner and the GX007 control unit. Considering the function of the unit, I expect the distance between the tuner and any terminal would have exceeded RS-232 and the environment could easily be too harsh for RS-232 as well (think static electricity and even lightening!!) An interesting device at any rate. Wish I had one. :-) bill

Did the freighter come with it or do you have to buy your own to use it?? :-) bill On 08/10/2018 10:13 AM, W2HX via cctalk wrote:
