 This port-powered, two channel converter allows your computer to communicate longer distances by converting TD and RD RS-232 lines to RS-485 signals. RS-485 also provides multi-drop capability. Model 485SD9TB features Automatic Send Data Control which enables the driver when data is present on the RS-232 side. Control of the driver is automatic at speeds up to 115.2 kbps.

The converter is powered from the RS-232 data and handshake lines whether the lines are high or low. No handshake line change is necessary to control the data lines. The RS-485 driver is enabled with each bit of data. The RS-485 receiver is disabled when the driver is enabled and is enabled when the driver is disabled. This converter is suitable for field service, where a power supply would add clutter, or anywhere you need compact, easy-to-use, economically priced serial conversion. Model 485SD9TB can be optionally powered by an external 12 VDC power supply.
