Factory reset P332

[Rade]

I am having a network access problem with my PIRA 332 RDS encoder after changing the network configuration.

The device is reachable on the network at IP address **10.50.0.5**, and it responds at the Ethernet level (ARP), but I cannot access the web interface or connect with the PIRA control application.

I performed a port scan and found that all tested TCP ports are filtered (no response), including port **7020**, which I believe should be used for communication with the application. The web interface is also not accessible on the expected ports.

For example, Nmap reports that all scanned ports are in the **filtered** state with **no response**.

The device appears to be alive on the network, but it does not accept TCP connections.

Could you please advise:

* Is there a default web server port for the PIRA 332?
* Is it possible that I accidentally disabled the TCP server or web interface?
* Is there a procedure to reset only the network settings without affecting the RDS configuration?
* Is there a hardware reset, serial recovery procedure, or a way to restore the network configuration?

I am also planning to connect a PC directly to the encoder with a static IP address to eliminate any network infrastructure issues.

Any guidance would be greatly appreciated.

Thank you for your support.

If the network configuration changes (e.g. subnet address) and the device's IP address has been set to a fixed value, it is natural that the device will appear unavailable for TCP connections or web management. The same can happen if you do not know the previous configuration of the device.

The procedure for setting the correct network parameters is always the same and was described in detail in the pdf manual (p132com.pdf). The P332 encoder was equipped with a serial port for local management, so you will need a serial connection and proceed according to the manual, section "2.2.1 Establishing a First Communication with the RDS Encoder". In this way, you can set network parameters, enable/disable TCP ports, enable/disable web management, etc. The RDS content itself is not affected. It is unnecessary to use port scanning or other low level network utilities.

Unlike our current models, the P332 was not equipped with Ethernet defaults button nor device discovery feature. In some cases, the described serial connection is therefore the only way to configure network parameters and make the device accessible over the network.
