Hi all,
I have a P275E Fm Monitor. This hardware works fine with the serial port and the software FM Scope and I configured the IP correctly.
When I try to connect to P275E trough TCP/IP, the FM Scope tells me "Connected to xxx.xxx.xxx.xxx:port" correctly but when a try to click on Tune with frequency selected nothing is happening.
Anyone else have the same problem?

Firmware version of P275E is 7.0.0.3 and the FM Scope is the latest version

Thanks!

Jan:
Run the Device Installer and make sure the serial port speed is set to 115200. See the device manual for details.

n.pison@springo.it:
Thanks! Now it's works fine!

Hi! I have the same problem with multiple P275E units.
Seems like the port settings are all ok:
RS232, 115200, 8, None, 1, None.
Seems like the FM scope connects to the unit, but no reply at all.
When connecting via serial cable, the FM scope works fine.
What may go wrong?
The units were working fine for months, after some time it begin to be first unreliable, and then no connection via internet.
Is it possible that the built in Lantronix lost serial functionality? Something may be to check with oscilloscope?

Best

Peter

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.
