DF58 RS-232/RS-485 Interface

New product
More info

This module converts the communication signal electric features from specification EIA/RS-232 to specification EIA/RS-485. Due to the fundamental difference between the purposes of both systems, the first one being ideal for point to point applications, it was implemented to work automatically. No control signal is needed to control the bus on the RS-485 side. It just needs to connect the transmission and reception lines on both sides to put the interface into work. The converting circuit provides a signal isolation to ensure a safe connection between the two systems. This module was designed to use DFI302/LC700 platform and so no power supply was inserted in the board. It consumes a voltage of +5Vdc from the rack to power the circuit.
