Yes. Data out (TX) can feed any number of devices but a device can only receive (RX) from one source.
My ZAON (TX) feeds both my GPS495 (RX) and Skyview (RX) so there is traffic on both.
My GPS495 (TX) feeds both Skyview (RX) and iCOM A210 (RX) so I get GSP NMEA on Skyview and VHF frequencies on my radio.
