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. The F485 converter can be powered via the power adapter supplied or by connecting an external 9VAC/VDC source to the power supply terminals located at the back of the case. The F485's versatility and simple design makes it ideal for use with all Multilin products in direct and modem communications.
