Block diagram RS-485, X16

The TQMa335x UART0 interface is routed to an RS-485 transceiver (SP491), which provides the signals at the 9-pin D-Sub
connector X16. The RS-485 interface is galvanically separated.
Die insulation voltage is 500 V

RMS

. A galvanically separated 5 V power supply is also provided.

In full-duplex mode the interface can operate with a maximum data rate of 1 Mbit/s. With an assembly option half-duplex is also
possible.

Remark

Full-duplex

0 Ω

Receiver always active (default assembly)

Half-duplex

0 Ω

Receiver controlled by RTS# (UART0.RTS#)

The RS-485 signals can be terminated with 120 Ω using DIP switches S4-1 and S4-2.
