Connect the output signals of the TXD17 pin to the driver input pins of the TRX (driver/receiver compo-
nents) connected to ports 1 to 7. Connect the output signals of the transmit-enable pins (TXE1 to TXE7) of
the MKY02 to the driver-enable input pins of the TRX connected to ports 1 to 7. Connect the receiver out-
put signals of the TRX to the input pins (RXD1 to RXD7) of the MKY02 (Fig. 3.7).
When using only selected ports in the HUB, fix the input pins (RXDn) of unused ports at High or Low and
leave the transmit-enable pins open (Fig. 3.8).
