The signals DTR and RTS provide the power to operate the DS2480B. The resistor in the TXD line and
the Schottky diode limit the negative voltage at the TXD pin of the DS2480B to 0.3V maximum. The
resistor is typically 4.7k. If the inverting driver is current-limited to 1mA the resistor is not required.
From the DS2480B’s perspective, this circuit will work with inverted signals of ±5V as well as 0 to 5V.
Depending on the voltage levels the host expects, it may be necessary to generate a negative voltage on
the RXD line. Figure 11c shows how this can be accomplished for a true RS232C system.
