Communication Converter
F485
-
The F485 is a self-contained device for converting between RS232, RS485 and fiber optic signals. The F485 is electrically isolated to improve communications in noisy environments. The converter uses internal switches to select the signal conversion type and communication rates up to 57600 bps. The F485 converter uses the data on the serial ports to determine direction and therefore requires no hardware handshaking signals from the computer.
