Build a JP1.x/JP2 cable using an FTDI Serial Converter Cable

slr_65,

I have some spare cables lying about (don't ask; it's a disease). I'd be happy to send you one for the cost of postage.

A thanks to gentzel for spotting me a cable! Thanks!

On another note, soldering used to be easy, with poor vision/depth perception now it's not so easy.

To help I bought a helping hands thing that has some clips to hold stuff and a 3" magnifying glass, it does help a lot!

A ham radio buddy gave me another tip I thought I'd pass along - most glass eye droppers can be popped out of their rubber cap and they fit in the Radio Shack rubber delsoldering bulb in place of the teflon tip. They have a smaller more compact tip so they fit into tighter places and with a smaller hole they have a bit more suction, they work well! If the solder cools off and plugs it up just use a lighter to heat it up and suck it on up into the bulb. Eventually the glass loses temper, but they're cheap off fleaBay, so buy a few and just toss 'em as they wear out. I used one tonight and it did work better than the stock teflon tip.

i m trying to connect my urc 7950 with this cable
http://www.ebay.it/itm/261101529602?ssP ... 1439.l2649

this way:

http://i59.tinypic.com/t6oxgy.jpg

but programs act like no remote is connected i tried tommy's test program too
and no remote found

drivers are ok... i see a com17 port
tried new battieries... even connecting 3.3v to pin1 no way...
some one can help me?

I think that cable is 2 Yellow, 3 Black, 4 Green, 6 White. You have it connected like Pin 1 is in the upper right of your picture. Is that correct?

i made some test to understand if the problem was the cable or something about my pc ( i tried 3 different pc !!!) so i connected this cable to the serial interface of "la fonera" (a little wifi router)
and it worked perfect... so the problem shoud be something about the remote!

the remote is brand new... and is working perfectly (normal usage...)

i really can't understand what is the problem...
when i try to run test with tommy's debug program the remote blink twice after test end... but even in the test i got "no response" like no remote is connected... at this point i really dont know... maybe pcb is broken???

how can i investigate? should i open the remote?? i m going to become crazy

sorry for my english

Try swapping white and yellow. Also try new batteries.

Since you suspect the remote, let's check its signature using 983 blink back to make sure that it actually is the 7950 we're used to. Is it 3029?

supertommy · Post by **supertommy** » Thu Oct 16, 2014 6:41 am

yes i got 3 blink 0 blink 2 blink 9 blink
for digit 1-2-3-4 so 3029

playing with realterm i got that

at this point problem should be in remote->software comunication...
timing?
maybe a speed baudrate problem?....

hum...heeeelppp

facts are that: remote go in serial mode, remote reply correctly at "I" and "V" commands.... so?

OK, that's great. Now let's concentrate on the software. Are you using RMIR to attempt downloads? Check Help/About and tell us which version (e.g. RMIR 2.02a) you're running, and which JP12Serial.dll version is listed. Also, startRMIR, attempt a download, exit RMIR, and then upload the file rmaster.err (typically in the same folder as remotemaster.jar) to the Diagnosis Section. Maybe we can see what the problem is.

Code: Select all

driver info :
Interfaces:
JP1.X Serial version 0.20
CommHID version 0.3
JP1 USB version 0.031
JPS version 0.1
JP1 Parallel version 0.02

Code: Select all

Starting normal download
Interface Name = JP1.X Serial
Port Name = COM5
Testing interface: JP1.X Serial
Interface matched.  Trying to open remote.
Port Name = NULL
Failed to open
RemoteMaster.windowClosing() entered

i think this is not really helpfull so i make a full serial log

this is jp1xtest.exe log

this is the debugtester.exe log

now the most important stuff... the log of what i do in realterm to talk with remote

http://pastebin.com/0s1Sj45a

at line 11276 we can see i have the reply from remote

11276 16/10/2014 19:36:05 IRP_MJ_READ UP STATUS_SUCCESS 53 3c 4a 25 S<J%

i think it's something about DTR setting if DTR is SET there is no way... this is what i do in realterm:

set dtr (this is done by realterm at startup)
set rts (done by realterm at startup)

clear dtr
clear rts

set break on
set rts
clear rts
set break on?(realterm?) (i didnt click but i see in the log)
set break off

after that i can talk with the remote... if i press "I" i have S<J%

this is the log of what allow me to go in serial mode:

where is the problem? my remote need a different initialization?

It looks like your interface is actually on COM17, but JP12Serial.dll is finding some other serial device at COM5, and is trying to use it.

In RMIR, try Remote\Interface\JP1.x Serial, and under Port Selection check Other and enter in COM17, or perhaps just 17.
