Unfortunately some radio systems manufacturers did not fully implement the SRXL standard but only copied the protocol from a different brand of radio systems to be compatible with already exisiting devices. Although this is not a bad idea at all, it has the disadvantage that these manufacturers loose the additional features and advantages that come with the unique manufacturer's ID.


The following receiver systems/receiver types support SRXL and work in combination with MICROBEAST and MICROBEAST plus:

Manufacturer Receivers
BEASTX All BEASTRX receivers
MULTIPLEX Receivers with M-Link data port (firmware update may be necessary)
GRAUPNER / SJ HOTT HOTT receivers with SUMD output (firmware update may be necessary)


The following receiver systems are compatible with SRXL as they directly implemented the SRXL protocol as specified for MULTIPLEX. MICROBEAST and MICROBEAST plus will work without issues with these receivers, but be aware that due to the same manufacturer ID they will be identified as MULTIPLEX receivers and therefore the preset channel assignment of MICROBEAST/MICROBEAST plus may not fit to your radio system, so a manual channel assignment is mandatory (see pages 28ff in MICROBEAST manual):

Manufacturer Receivers
JR propo JR X-Bus (select X-Bus Mode_B output in the radio)
Jeti Receivers with Jeti UDI output (firmware update may be necessary)
