An enhanced parallel port interface for controlling and monitoring experiments

In this paper we present a circuit for enhanced parallel port (EPP) interfacing that is of low cost and great versatility for general use for data communication in research laboratories. The communication is bi-directional and its speed is higher than 500 Kbytes s super(-1). This circuit has an addr...

Description
Summary:In this paper we present a circuit for enhanced parallel port (EPP) interfacing that is of low cost and great versatility for general use for data communication in research laboratories. The communication is bi-directional and its speed is higher than 500 Kbytes s super(-1). This circuit has an address decoder, which permits individual communication with eight items of equipment of 8 and 16 bits, with an extra status bit. The addressing system also allows insertion of up to 16 such interfacing circuits into the same computer EPP output, each of which can be independently reached.
