EF Johnson 5300 53SL Ascend ES Radio Programming Cable


 

Hello All,

I hope that you are well.

I have several 53SL ES mobile radios that I am trying to program.

I was given a USB <---> Mic connector cable No. 023-5300-98001? (5300A0110S03576) cable with the radios.

When booting up the radio the display screen shows the following V6.05 A21 then V6.12.5.

Radio model No. is 242-547G-203SBAL6

I have loaded the following software onto both 32 and 64 bit windows systems ,? , and? . the cable is not recognized by any of the software versions on either 32 or 64 bit windows systems.

I am not able to locate drivers which would make the cable recognized.

RFguys sells the following? , however when I attempt to order it the website transitions to a page that says they are not being taking orders now.

Everything that I have been able to read on the web states that all of the EF Johnson radios of this series 53SL ES are difficult to program with USB cables and that the EF Johnson programming software has difficulty recognizing USB programming cables.

Several Questions.

1) Does anyone know of a source of? DSUB-9 (9 pin) serial connector programming cables?

2) Does anyone have the pinouts for the DSUB-9 (9 pin) serial connector programming cables?

3) Is there a radio accessory port <---> DSUB-9 (9 pin) serial connector programming cable?

4) Based on what I observe when I boot up the radio ( V6.05 A21 then V6.12.5.) what software should I be using?

5) What am I missing in the whole process of programming EF Johnson 53SL ES radios?

I have spent ~ 20 years programming Motorola, Kenwood, and Icom commercial and amateur radios.

The EF Johnson products are new to me and are presenting a challenge.

It's good to have a challenge every once in a while.

I thought it best to consult the experts for help.

Thanks for your help and support in this matter.

All The Best & 73's (too)

With Best Regards
