Product information

USB Expansion Module 433.92Mhz RFXtrx433XL Transceiver ( RFXCOMM )

Hello! Meet the RFXtrx433XL, RFXcoms big brother with double the memory.

So what are the differences ?
- twice the memory, the RFXtrx433XL has a dual memory, so that it can now have all currently supported protocols in one firmware version.

- Pro-firmware: the protocol detection in the receiver has been completely redesigned, making it possible to enable multiple protocols.
In the older Ext and Ext2 firmware for the RFXtrx433E, some protocols were not received or received reliably when another protocol was enabled. The ProXL firmware does not have this limitation. This firmware design is also available for the RFXtrx433E as Pro1 and Pro2. Due to the memory limitation there are still 2 versions for the RFXtrx433E.

- RF noise level: the new Pro firmware (Pro1, Pro2, ProXL) detects the RF noise level during start-up of the receiver and RF signals above this level are processed. It is required to install the RFXtrx433XL in a good location with a low RF noise level, so that a good reception quality is guaranteed. The noise level is displayed in RFXmngr on the Main menu. A value of 92 with the standard antenna is acceptable, but lower is better. A general rule is not to place the RFXtrx433XL near a Raspberry PI, routers or other electronic equipment, power cables or metal pipes.
Important note: the RFXtrx433XL may only be programmed with ProXL firmware. When a Pro1 or Pro2 is flashed in the RFXtrx433XL, it remains in the bootloader and requires a special procedure to make it operational again, the housing must be opened and a temporary connection (without soldering) must be made on the PCB . The recovery procedure is available in the RFXtrx user manual, chapter 19.

- Modified USB interface: the RFXtrx433XL has another USB FTDI interface chip. It uses the same USB drivers as used by the RFXtrx433 and RFXtrx433E and requires no action in the operating systems.
A connection is available for a serial interface to replace the USB connection. This connection can be used to connect an RS232 or LAN interface. See chapter 18 in the RFXtrx user manual. Select an interface that does not produce RF noise. As an example, RFXCOM has tested the USR-TCP232 LAN interface, but this interface module produces too much RF noise at 433 MHz and the RFXtrx only receives a sensor at a very short distance.

Smart-meter interface: there is a special serial interface connection on the RFXtrx433XL PCB to connect the Dutch P1 smart meter or an interface for the French Teleinfo meters. See chapter 16 & 17 in the RFXtrx user manual.
