Probably too much load on the serial signal.

Either boost, the signal.

Or connect them in series and alter the code on each to re-transmit to the next, whatever it received.

Are you using WS2812 LEDs? If so, the interrupts needed for serial communication are blocked while the LEDs update.

UCS1903 pixel and I am using only Tx of one controller and connect to Rx of remaining 5 controllers
