  • Extend RS-232 data signals up to 1.2 km (4,000 ft.)
  • Change RS-232 TD and RD to balanced RS-422 signals
  • Automatic Send Data Control - no software drivers necessary
  • Baud rates up to 115.2 kbps
  • Powered from RS-232 handshake lines - no power supply required
These port-powered, two-channel converters change TD and RD RS-232 lines to balanced RS-422 signals extending communication distances up to 1.2 km (4,000 ft.). Automatic Send Data Control feature enables the RS-422 driver when data is present on the RS-232 side. Control of the driver is automatic at rates up to 115.2 kbps. The RS-422 driver and receiver are always enabled.

With port-powering, a power supply is not required. Power comes from the DTR and RTS RS-232 handshake control lines. At least one handshake line must be present, in either the positive or negative voltage state. This permits use in applications without worrying about software control of the handshake lines.

If port power is not sufficient, select the 422PP9TB which can be powered from an external source. This version also allows you to connect the RS-422 signals via a terminal board instead of a DB9 connector. Converters are configured to transmit both directions in an RS-232 and RS-422 system. RS-232 pinout connects directly to a computer’s COM port or any other DTE device. Connections to the RS-422 side are made through a DB9 for the 422PP9R or terminal board for the 422PP9TB.

These converters are great for field service or "in-line" cable applications
