Hi Majid

A repeater can be considered an a single port splitter. With any splitter, other responders may be placed on the responder port of the splitter or several splitters all on one bus.

Splitters may also be cascaded, as could your single port splitter or repeater.
Be aware, that the load on the bus (whic is related to the 32 devices) is not the only factor to consider. With each cascaded device, more bit distortion will be introduced, excepting in the case that the downstream signal is regenerated...

If RDM data is received on one uP UART and re-transmitted on another, significant delay will be introduced, making it fairly problematic to start cascadeing devices.
