  • Adapter aid for the trouble-free connection of computer peripherals to a device interface controlled by computer systems
    Patent number: 5101481
    Abstract: An adapter aid (ADE) is connected to a device interface (PS) provided for the parallel connection of computer peripherals (PE) to a computer system (RE), and to an additional device interface (PSZ) to which further computer peripherals (RE) can be connected in parallel fashion. In the adapter aid (ADE) the bidirectional and/or unidirectionally effective data and control interface contacts of the two device interfaces (PS, PSZ) are directed via bidirectionally and unidirectionally controllable, switchable and signal regenerating switching means (BST;EPST;LTE;BT). These switching means (BST,DPST,LTE,BT) can only be switched effectively if a computer peripheral (PE) is connected to the additional device interface (PSZ) and currently no information is transmitted via the device interface (PS) by another computer peripheral (PE) or by a computer system (RE).
