Last Click Serial Port
Locked
 
|
Since I have incurred a situation at lest 3 times on my K3S, since it might help someone I thought I would share some info. On occasion I need to un-cable the K3S when working an something and like a fool thinking when I put it all back together it is going to work first time. I do have everything labeled so I do get everything into the right connector. The problem I have had to arise several times, once everything is ready to check the, the RS232 serial port will not communicate.
After a lot of work each time it has turned out to be that the RJ45 connector for the RS232 jack, even though what appeared to be fully plugged in, pushing on it there would be a faint “click” signifying it is truly fully seated. From where I thought I had it fully plugged in to actually being full could not have been a 64th of an inch if that. Not even sure if there is any further travel I just hear the faint click. So if you use the RJ45, even though the RJ45 appears to be in fully, if you have com port communication problems to your computer or cant talk to your P3, see if you hear that faint “last click” in the RJ45. It is not just my particular K3S, I have seen the same situation on a second one. 73 Mike K4PI ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[hidden email] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [hidden email] |

Another "gotcha" is forgetting to reset the RS232 baud rate.
This bites me after every FD because N1MM is different from my Palstar AT-AUTO. 73, Kent K9ZTV On 1/27/2019 9:00 AM, Mike Greenway wrote: > . . . so if you use the RJ45, even though the RJ45 appears to be in fully, if you have com port communication problems to your computer or cant talk to your P3, see if you hear that faint “last click” in the RJ45.

Why not use the USB cable to computer? My RJ45 goes to P3.
And, yes, it must be seated firmly.

In reply to this post by Mike K4PI
Mike and all,
That is my experience with RJ45 plugs as well. Rather than just pushing on the 'boot', it is helpful to pull the boot back a bit and push on the connector body itself, then slide the boot back in place. That is true not only for the K3S RJ-45 connector, but any RJ-45 in my wired ethernet network. Listen for that final click. 73, Don W3FPR On 1/27/2019 10:00 AM, Mike Greenway wrote: > Since I have incurred a situation at lest 3 times on my K3S, since it might help someone I thought I would share some info.
