If you lose the communication over Ethernet due to incorrect network settings, forgotten password or port number etc., there's always a possibility to restore the configuration using the local port (Port 1), i.e. the serial port on the P332.
- Connect the RDS encoder to the PC using the original cable included. If you use other cable, make sure it's a crossed cable (also called null-modem or laplink).
- If your PC is not equipped with RS232 port and you're forced to use USB to RS232 adapter, this should be FTDI chip based as this is the only reliable solution.
Low-cost Chinese adapters based on Prolific chip often exhibit erratic behaviour and we do not guarantee function with these adapters. Usually the Prolific drivers do not support baudrate switching while the port is opened so automatic baudrate detection does not work in the Magic RDS. Look at the P332 display, parameter SPEED, and select that speed manually in the Magic RDS (Options - Preferences). Confirm the Bidirectional communication. - Once you establish the connection, select RDS Encoder - Device Setup in the menu and restore the network settings to desired values. Reset the device.
Unchecking the Bidirectional communication checkbox, it may look like the communication is working but this is only due to the fact that no response is received nor expected. Check the cable and wiring.
P.S.: The internal battery is used only for real-time circuit backup. User is not allowed to open the cover. There's nothing to be set.
