Hi Kurt,
I built this. I didn’t use the optional MAX3232 serial module.

There is also this module.

No, there isn't a upgrade manual.
Here i copy the detailed instructions i wrote for my personal use.
Hope the community can use it.
Steps to upgrade the firmware on PA100D clone amplifier from EA8DJR Luca:
This PA100D clone amplifier came with v. 1.05q firmware without a bootloader to update via serial port.
The most recent firmware is v. 4.01a build 3 from 5B4AIY Adrian, his great job was intended to upgrade the original Juma PA100D from OH2NLT and OH7SV, but can be used also with the clone.
This firmware (after correctly calibrated) solve almost any problems i read about the use of this amp, from the incorrect reading of the P.in, the difficulty to use some ATU because
of SWR protection, all the doubts about the effective P.out etc. etc.
All the software and documentation i used was shared by Joe, KD2NFC at this link: https://drive.google.com/drive/folders/1hUjZxdLiu8qhNi1OJin17i58c4xb3bFp?usp=sharing
First of all you need to write the bootloader into the unit.
For this you need the interface PCKIT 3 (also old v.2.2 may work), install the software V 3.3, open the amplifier and solder the comb pins tha came with the pckit on the J19 interface
remembering that pin1 is the one marked with a white square and that need to match with the white triangle on the pckit connector. So connect the flat cable provided to pckit with the
black cable aligned with the white triangle, the other side with the black cable aligned with the white square. Connect pckit via the usb cable to your pc.
Download Bootldr_Juma-PA100_v104.hex, press and hold the PWR button on the amp. until the process is finished. Launch the program PCKIT3 v3.3 the program must recognize the eprom type.
Click on button Auto Import Hex+ Write device. Choose the file Bootldr_Juma-PA100_v104.hex and continue. The program will do everithing and will tell you when the procedure ended successfully.
Then click again on the button (Auto Import...) to finish. Release the PWR button on the amp. Done.
If it don't work, close the program and redo from start.
Now you have the bootloader working and you can update the firmware with the procedure described in the original PA100D manual thet you find in the google drive shared folder from KD2NFC
with the ingenia dsPICbootloader using the file Juma PA-100D.hex (in the zip relative to V.4.01a build 3).
I had some problem with missing dll with the ingenia so i preferred repeat the procedure with PCKIT3 using the file Juma PA-100D.hex
This firmware is completely different from the v.10x series and will give one error on the first start causing to reload the default calibration.
For this reason you will need to redo the calibration.
Do not affect the use of the amplifier, just the accuracy of the displayed informations.
You will need a voltmeter which support 20A and a precise watt meter. Take your time,
is important to show correct informations on the display and also you can configure new features.
Before start put the amp on AUTO. The procedure is in the JUMA 100D updated v.4.01a manual.
Hope to help with this small manual, remember to read carefully and that firmware upgrades are always at you own risk!

Hi all, I received my RS-928 version recently and yesterday upgraded it first to the 1.04 with hex+bootloader and then the latest 4.01a. I used a PICkit 2 as I had one on hand and it supports the chip - I had no problem at all with using that older programmer. Holding in the power button on the amp (and of course powering it with 12v) was an absolute must when attempting to upgrade the firmware. The software detects the powered chip and adjusts accordingly. I did the 4.01a update with the PICkit 2 while I had it connected. It looks like I'll need to run through the calibration process at some stage but otherwise everything seems to work just fine. I do need to change the colour of these buttons though :)

Just to be sure, make sure you have it plugged in correctly when you go to do this. The white triangle on the programmer denotes pin 1, and the one pin surrounded by a box is pin 1 on the board. You don't want to put that thing in and try powering it while incorrectly wired. (while the others are collectively surrounded by one box). Make sure the wire between pin 1 on the programmer and the board match up and you should be good to go.

My experience with the pickit3 standalone programming app was a mixed success. You can try to use the built in "Target Power" feature of the pickit3 to power the chip while writing, or you can try to Hold the power button to give it power long enough to write the image. If it failed, I would suggest erasing before writing the image again. For powering via the pickit3, i think I used 4.5v with both "on" and "MCLR" checked. I would try holding the power button while flashing and see if that helps. You may also need to recheck communications with the chip to make sure it's selecting the right device / chip model/version/whatever.
Make sure to flash the combined bootloader/firmware package first (available at http://www.jumaradio.com/juma-pa100/juma_pa100_software_for_developers.html) if you want to have the bootloader working. Then, you can just flash the 4.01a b3 hex file with the ingenia flash tool using the flash writer mode from the bootloader. I would actually recommend this myself since that way you shouldn't need to go and crack open the case again to reprogram it later on.
Hope this helps.

It's practically the same as original. Also, the eBay version does not come with the boot loader. You can install the boot loader and latest firmware as well.
I just dumped the folder where I kept all the Juma PA-100D files to my google drive. Everything should be in there to install the boot loader and firmware, including the remote control program. https://drive.google.com/drive/folders/1hUjZxdLiu8qhNi1OJin17i58c4xb3bFp?usp=sharing
The boot loader is supposed to allow you to update the firmware using the serial connection on the HL2 using the dsPICbootloader. But since its not installed you have to use the PICkit2 and connect it to the pins located on the backside of the face of the amp to connect directly to the eeprom and program it. Its fun stuff :) use the .hex files with the PICkit2 located in the folders for the boot loader and the firmware version you want to update to.
I know I read every post in that forum for Juma PA-100D a hundred times to figure this out. LOL!
I also included the files for an ESP32-XPA125B module I built for the band switching using band volts.
Hope this helps getting you guys started. Good luck.

I see lots of people posting about this amplifier with pro/cons etc. I did buy one to use alongside one of my Hermes Lite 2. One thing I really wished it had was the remote options that were introduced in the later firmware for the Juma Amps that was modified by 5B4AIY. Has anyone been able to load one of those versions on one of the clones? I know when I telnet into the serial port I see reference to his callsign, and the menus look very familiar to the original version 1 firmware.
Also out of curiosity the RoWaves "Official Version" shows as backordered. Are they shipping them? The price isn't substantially more but I was really unclear if they were available/shipping.

I was able to successfully get both the bootloader/firmware installed with the pickit3 and then updated to 4.01a build 3 after that with the ingenia app using a different ftdi rs232 to usb adapter with some custom cable built to connect to the 3.5mm stereo jack. We're in business. Even the remote control works. Thanks for all the info and work!

I had an issue with USB to TTL devices. You need to use a USB to RS232. That is after you updated the firmware to a version that supports the serial connection.

Hoping you can provide some insight since you actually got this thing upgraded. When I try to connect to the RS232 with the appropriate cable, I only get a bunch of garbled text back. Any suggestions there?
Best,

It's practically the same as original. Also, the eBay version does not come with the boot loader. You can install the boot loader and latest firmware as well.
I just dumped the folder where I kept all the Juma PA-100D files to my google drive. Everything should be in there to install the boot loader and firmware, including the remote control program. https://drive.google.com/drive/folders/1hUjZxdLiu8qhNi1OJin17i58c4xb3bFp?usp=sharing
The boot loader is supposed to allow you to update the firmware using the serial connection on the HL2 using the dsPICbootloader. But since its not installed you have to use the PICkit2 and connect it to the pins located on the backside of the face of the amp to connect directly to the eeprom and program it. Its fun stuff :) use the .hex files with the PICkit2 located in the folders for the boot loader and the firmware version you want to update to.
I know I read every post in that forum for Juma PA-100D a hundred times to figure this out. LOL!
I also included the files for an ESP32-XPA125B module I built for the band switching using band volts.
Hope this helps getting you guys started. Good luck.

Great to hear, so basically the clone takes the juma firmware. pretty good clone.

Hi,
I was able to update the Juma clone with the latest firmware.
You can get the firmware the remote program here. http://board.jumaradio.com/viewforum.php?f=12 <http://board.jumaradio.com/viewforum.php?f=12&sid=3b5857bc92ed54e38187da05c775b575> &sid=3b5857bc92ed54e38187da05c775b575
I had to buy a programmer to program it. The PICKit 3 that you can get from Amazon. https://www.amazon.com/Microchip-Programmer-Debugger-Emulator-Controller/dp/B07WS5JL3Z

did you happen to every get a answer ? I was thinking of getting the clone as well and one of the really nice features would be the remote/serial connection to the amp.

I see lots of people posting about this amplifier with pro/cons etc. I did buy one to use alongside one of my Hermes Lite 2. One thing I really wished it had was the remote options that were introduced in the later firmware for the Juma Amps that was modified by 5B4AIY. Has anyone been able to load one of those versions on one of the clones? I know when I telnet into the serial port I see reference to his callsign, and the menus look very familiar to the original version 1 firmware.
Also out of curiosity the RoWaves "Official Version" shows as backordered. Are they shipping them? The price isn't substantially more but I was really unclear if they were available/shipping.

I don’t recall the jumper number on the board but the header pins need to connected to where I circled in the image.
Try keeping the amp powered up when using the programmer as it will give the chip power. There maybe something going on with the pickit not continuously supplying power.

Definitely have power to the amp and keep the power button pressed while you program with the hex file. You should get a warning from the PICKit software telling you that the micro has power.
