Are there any hacks for Siglent 3303x-e power supply?

I just unlocked using the check bypass method and I kept my MAC address/serial number so it seems safer. You do not need a debugger by the way. The exe is not compressed so you can directly edit it with an hex editor like HxD.
1 - Open EasyPower.exe with an hex editor and look for 0F BE 55 0C (there is only one occurence)
2 - Just before that occurence, replace 0F 84 A4 00 00 00 by 0F 85 A4 00 00 00
3 - Flash the firmware using the new "no check version" of EasyPower you just created

Although more universal that method is riskier since you can flash any FW... untested and/or improper versions also...

Hello!

Do anyone know how to change the mac address of these power supplies? I've two of them and both have the same mac address, but i can't have them both plugged in lan network

best regards!

Welcome to the forum.

There is a new bug introduced in V1.01.01.02.07R2 firmware and not present in V1.01.01.02.05 where the  IP address is not saved correctly.
The patch files below corrects this until a full firmware version is released.

Note
Remove the txt file extension and install the ADS file in the normal way.

Hopefully it is alright to dredge up an old topic. I wanted to save someone some time and/or heartache.

I purchased a SPD3303X-E that arrived with hardware version V6.1 and software version V1.01.01.03.10. I didn't pay too much attention to this and tried tv84's procedure from the original link in this thread. EasyPower warned me that the firmware did not match, which I should have heeded but am too stupid to quit. I performed the EasyPower hex edit and forced the firmware update and was met with a dead unit.

 

During my panic searching and self-loathing, I couldn't find any recovery instructions. I figured Siglent had some sort of bootloader or firmware update methodology, and held all the buttons while powering it up. Found that holding the adjust knob in while powering on boots to the firmware load screen, huzzah!

Firmware Recovery Steps (Hardware V6.1)

• Download SPD3303X-E V1.01.01.03.10 ADS from Siglent
• Power off
• Hold adjust knob in
• Power on. Device should boot in firmware mode.
• Start EasyPower -> Version -> Upgrade
• Choose firmware mode and select the SPD3303X-E V1.01.01.03.10 firmware*

*Note: I used the hex-edited EasyPower exe for this, but should work without it

While researching, I found that hardware V6.1 was incompatible with the previous (V1.01.01.02.yy) versions of the firmware, which was likely causing the issue.

After getting through all that, I was able to send the SDS3303X OS using the hex edited EasyPower. Doing this removed my cal coefficients, so I calibrated the unit using https://www.eevblog.com/forum/testgear/siglent-sds3303x(-e)-calibration-fw1-01-01-02-07r2-best-practice/ and it's working like a clock!

Hope this helps, and thanks to everyone for the great tools and documentation.

Glad you succeed! My 3303X-E will just boot into the firmware upgrade state after I directly upload the firmware of 3303X into it using the modified easypower.exe. Did I miss something?
-edit:
I didn't read the Release Notes first. It stated that: "B. < V6.1 hardware version of SPD3303X/X-E do not support upgrading to this version (SPD3303X_V1.01.01.03.10.ADS)". The result was the PSU will boot into the firmware update screen after reboot.

Welcome to the forum.

Maybe check your hardware is V6.1 or for an earlier version for which you must use the correct FW version.

Thank you, My Hardware version was V3.0. I am trying to get NI MAX to recognize my PSU but so far I had no luck. I have both the USB and LAN connected, NI MAX can see a USB VISA device but can not do a thing, and it can't see the PSU on LAN although easypower can. Maybe I missed a driver or something?
-Edit:
I installed labview with NI package manager and now I can connect to the PSU with LAN. Maybe something needed was installed along side the labview.

Quite likely.

If you download the free EasyPower SW and read the install instructions, it requires NIVISA Runtime at the least (smaller package than NIVISA full install) for the connectivity drivers.

What is your PC OS ?
Some think they know best and install the incorrect driver especially for USB and that needs be removed and the correct one linked to the device.

Files attached for guidance.

Thanks a lot for the kindness!
I will briefly describe what I have done for future me or anyone interested:
Note: I have a 3303X-E with hardware version 3.0
- Download and install Easypower from Siglent, modify easypower.exe per @optotester's instruction.
- Download and install NI package manager.
- Install NI-VISA, NI MAX, and "LabView and drivers" from NI package manager. (I think it is the "driver" included by "LabView and drivers" that matters.)
- Connect to the PSU via LAN in NI MAX. Once done, the VISA test panel will be available.
- Write the "FACTORY ON" SCPI command per @tv84's instruction. (May not be necessary)
- Upgrade the PSU with this firmware (SPD3303X-1.01.01.02.05.ADS)
- The PSU will reboot and become 3303X

-edit:
I didn't read the Release Notes first. It stated that: "B. < V6.1 hardware version of SPD3303X/X-E do not support upgrading to this version (SPD3303X_V1.01.01.03.10.ADS)". The result was the PSU will boot into the firmware update screen after reboot.

What is the  firmware update process for an SPD3303X-E that has been updated with the expanded resolution.   
The current condition:
        FW shows 1.01.01.02.05
        HW version V3.0
        Product type SPD3303X

How does one update to the latest FW 1.01.01.02.07R2 without messing up the expanded resolution?  Normal SPD3303X update for Siglent  or do I need a special file?

Just use the EasyPower software and the normal SPD3033X firmware (not the -E firmware) as usual.

Thanks, that is what I thought -- worked great
