STX PROGRAMMING PROBLEM

CHEFA2001 · Post by **CHEFA2001** » Thu Nov 01, 2001 6:31 pm

I know this is likely to be a simple thing but does the STX821 radio require unique rss or does the STX or STXlab work for it?

HELP

Thanks guys

All STX radios program with the same RSS, even the odd STX800, just make sure its current enough for the firmware.

I someone were to use lab rss, lab r03.01.00, Would that work for a radio with serial starting in 626amw, and a gps 1-1
510125us?

I am not getting a connection when I try and read the radio and I converted a stx speaker mic to a programming cable from the batlabs pinout and I am quite sure that the connections are right.

Let me know if you have any ideas....

I know that some astro sabers cannot be read with the older b3.4. whatever depot tool and I thought that this might be the same problem, but at least with the astro situation, it tells me the block error message and just does not say serial blah blah blah like I am getting now.

Hi:

Sounds like you have wired your
cable incorrectly

Here is the way it should look from
the wiring side of the connector

Wiring Side
---Top---
--l---l--
--l---X--=====>Pin 1 DB25F
--l---l--
--l---x--=====>Pin 15 DB25F
--l---l--
----o----
==screw==
==============> Pin 11 to 4 is shorted DB25F

Hope that calarifys things a bit

Hi Monty, Thanks for the reply.

I am lost in your reference to a screw underneath the pins as the only screw I see is to the left or to the right depending on which side of the stx's programming cable insert I look at.

Let's say that I am looking at the side of the insert that would have been the speaker mic part that inserts into the stx radio 's universal connector, OK? SO, Now I am looking at Pins that are gold, and the area of the connector which has two holes for screws is to my right.

Now, From what I understand on Bat pinouts, The second pin up from the bottom in the left column should be the wire that goes to pin 15 on db25, and the wire that goes to pin 1 on the db25 connects to the second pin down from the top on the left column???

Someone please tell me if I am wrong but I think that the radio may be non readable as I have cut and re-solidered about six times with NO luck at all.

Anyone in the NY, Long Island Area who wants to make a few $$ and have lunch on me????

Email me!

Hello.

The cable is simple.
Start from the antenna, draw a line down, count the pins, 1 to 5, now go to the other side, this side is toward front, count up 6 to 10, 7 is the pin that is next to the bottom, front, skip one going up, this is pin 9, this is ground.

E-mail me if you cannot get this to work.

Thank You.

Well IF Cowthiefs pinouts are correct, then I would have to say that the pinouts that batlabs has is wrong.

Anyone have any ideas?

Batlabs pinout wrong?

Thank You.

P.S.
I checked my cable, a cable I know to work, this IS the pinout.

Thank You.

This radio is now being thrown into the trash can as I cannot get it to read and I have re-solidered the connections about eight times.

I know that I am getting the pinouts right so there must be something disabled in the radio or blown out or the such.

Too bad as I was really looking forward to playing with this radio.

I guess to get a working STX I would have to pay one of those morons on ebay $299 for one that is alledged as 100% ok.

Uggh, I was soo looking fwd to playing with this radio tonight.

Anyone have any ideas as to whats wrong?

Here is the info that comes up when radio is put into test mode:

626
AMW0222
GPS 1-1
510125US
060125US (SHOWS WHEN I DEPRESS THE PTT)

Are you shorting pin 7 to 9 to put this radio in test mode?.

If so, send me a private message, I will give you a call, I might be able to figure this out.

Thank You.

Hi, SOrry to be such a pest.

I am shorting the followign two pins to go into self test. WHen I am looking at the radio from the left side of it, looking right at the universal connector, I am shorting the second from the top on the right row and the second up from the bottom.

I have made many programming cables from scratch and from speaker mics and NEVER had a problem until now, and NOW I dont know if its me, the cable or the radio.

Don't toss that radio in the trash. There's hope yet, and you can still get some money for it 'as is' on ebay.

The simplest way to test an STX programming cable is, believe it or not, to touch the contacts to your tongue and then hit the 'read radio' button. You'll feel a pulsing tingling sensation that is sort of odd but it's definitely nowhere near painful. A good 9 volt battery will hurt a little, but it's no more than 5 volts coming out of the cable. If you feel that pulsing tingle, you can be reasonably sure that the programming cable has good conductivity and next you want to be sure that the connections are right.

The only two pins that need to be connected in a programming cable are the second and fourth pins on the radio connector, counting from the top, at the side of the connector that is nearest the front of the radio. These are the pins that are labeled 7 and 9 on the cable shown in the diagrams at batlabs. Remember, they connect to the side of the connector that's near the FRONT of the radio.

If your controller's good (it probably is if you can put it in self test mode) and the cable is good, there may be an internal problem with the wiring. Most likely it's in the control top assembly, which comes off by loosening (not removing, just loosening) the two screws on the top panel and pulling up gently. There is an antenna connector in there that's nearly an inch long and it's silver. Grab the two ends of it and carefully pull it apart. Then you can inspect the control top wiring fairly easily.

Pick up another cheap, working basic STX off of ebay or some place, just for the parts. At worst, if it's a working radio, you'd swap the housing and the controller with the better ones you already have.

Hello.

Yes, that is the same 2 pins used for programming, this tells me that the controller IS responding, the radio, most likely, is just fine, there are a few questions, is the contact clean, both sides?, is the cable good?, check with a VOM,
does the RIB work with other radios?, yes, but just to check.
If this does not work, send me e-mail.

Thank You.

When addrssing the STX821's for reading / writing, you
should make sure your Contacts are Clean, and free of
debrie. Also I would recomend a stable programming
platform.<p> If you give up, I have STX821's which
have the Enhanced Boards for 195.00+Shipping.<p>

Thanks to all who replied to this thread.
I removed the top of the radio and then re-attached it and have not had a problem reading and writing it since.

Also if anyone has a codeplug for an STX please private message me as I want to see what a properly programmed one looks like. and to mess with.
Thanks
