I agree. It would indeed be helpful for old geezers like us :-)

RDS Spy / Request for lager font of PI code in RDSSpy
« Last post by GuidoS on Today at 03:00:32 pm »
Hello,

Since screen resolution of monitors is always rising, eyes are getting older etc I would like to suggest to enlarge the font of the PI code in RDSSpy.  It is often difficult to distinguish between 8 and B and may also a few other characters. I think this would be welcomed by a lot of users.

73,

Guido.

P275 FM Analyzer / Re: Problem TCP/IP control from P275 e FM Scope
« Last post by Jan on September 10, 2025, 09:34:52 am »
Received all three units. Thank you. They are operating normally in entire range of temperatures. Two Lantronix devices were set to incorrect speed 9600 and 19200 respectively. After setting 115200 everything works. Will keep it running for some day but I don't expect any issue. I guess you were not connected to the Lantronix but to some other device or service in the network? Or to port 80 instead of 10001?
Current P275E fw version supports also connection from a web browser so the HW operation can be verified that way as well.

Thanks for the information. Please feel free to contact me via email to arrange the replacement. I'm eager to find out what happened to the Lantronix HW or SW.

Hi, most probably the lantronix is the cause of problems.
Tried with different PC, no luck, tried to measure any data on lantronix pins, no luck.
Tried to set up the gpio port on the lantronix to output, tried sending high / low, no luck.
The embedded web server works, but seems no electric signal on the pins.
When using the micro usb port without the lantronix board, every communication works fine.
So I'll send back the devices for checking.
Thanks for help.

Best

In terminal, type for example ?F for getting current frequency. The terminal speed, if applies, shall be 19200.

Hi,

maybe something to test via terminal app? did not check the command list, can you recommend something?
Will try with different pc, the pc is very standard and very new, no extra virus killer yet on the machine, fw is turned off for the tests.
Do I need to run FM Scope as admin?

The firmware update works so there's probably nothing wrong with the device communication port. The firmware update uses the same communication channel like the FM Scope. I would focus on the PC software. I don't have any simple steps you can follow because such problem has never been reported. I would recommend to send the unit back to us for inspection. Try different PC first and turn off antivirus etc.

Hello Jan,

No luck, tried once more. The only thing what is communication with the motherboard, is the firmware update utility.
It seems fw update runs fine to 2.2e r2.
But after that there is no communication with fmscope. FM Scope opens the com port or network com port, but there is no data coming from the device.
Tried with two different devices.
Disassembled it, tried the connection between motherboard and ethernet to serial board with multimeter, the connection is ok.
There is no oxidation sign, even there are no bird's nests or mouse family integrated :), everything is clean and tidy.
FM scope is 1.7.1, OS is win11 pro x64. Lantronix version is 7.0. something, did not try to update it.
Tried with two different usb to serial converter.
I did not tired with micro usb cable.
Any idea to test? Maybe an online video call (viber or so?)?
Next day I may be take my oscilloscope, what can decode RS232 (never tried yet), and I may check the data pins of converter.

Best

I administer the P275E devices for more than 7 years, some operating in outdoor conditions. They still work fine and such problem has never been reported by anybody. Thus I guess it is not a hardware issue. But who knows... Of course, we can replace your device with another one at any time under warranty.

Apply the latest fw version 2.2e r2. Go to the XPORT web interface and select Apply Defaults. Then go to the XPORT web interface again and configure the Network and Serial Channel according to the latest pdf manual.

If this does not help, disassemble the two internal boards and check/clean the golden-plated connector between them (referenced as J2 on both boards). The pin assignment can be found in the original P275 manual.
