General Discussion about the RDS / Re: RVR TEX300LCD built-in RDS encoder (P232) board setup
« Last post by Jan on August 27, 2026, 09:57:33 am »It is true that we have supplied a certain amount of P232 chips to R.V.R. in the past, but the cooperation was terminated because they violated the terms of business and subsequently stopped communicating.
Unfortunately, I do not know the technical details of their implementation. If your device really has a P232 chip and UECP communication works for you, then the P232 model must also work. Unless someone blocked ASCII commands using the PAC function. However, this is normally not possible to do from the port on which communication is being carried out, it would have to be done from the other communication port. Moreover, this blocking cannot be performed at all on one of the ports. I do not know which communication ports are accessible in this device.
Try both communication ports, if possible. Communication must always work on one of the ports, it cannot be blocked by any setting. If only one port is accessible on the panel and it is the blocked one, you can also solve the situation by replacing the EEPROM (24LC512/M24512). But it's quite possible that there's a completely different type of encoder inside that doesn't come from us.
