Introduction

This Driver allows communication with pressure transmitters from series 30 by Keller Pressure AG. There are functions that allow defining and reading settings and also reading and writing values in transmitters.

Communication must be performed using a serial port, by using a converter from RS-485 to USB model K-104, from the same manufacturer, or any other converter from RS-485 to RS-232. This Driver was originally tested with that USB converter to RS-485. When using this converter, a virtual serial port for communication with a device is created. This virtual port is usually port COM3. A device must be connected to the converter via RS-485 output, and then the converter connects to a computer via USB port. For more information, please check manufacturer's documentation. For more information, about the configuration of IOKit library, please check topic Documentation of I/O Interfaces.
