DISCRETE DATA COMMUNICATION DEVICE Russian patent published in 1994 - IPC

FIELD: computer technology. SUBSTANCE: device has interface trunk with n+2 lines, units for duplex data transmission, transmitter, pulses duration selector, receiver. Device communicates with the other devices by communication channel. Executive unit, n-1 data signal indication units, control signal indication unit, three-wire handshaking system unit, handshaking signal indication units. Alternating data transmission is provided in the device of condition of interface trunk. Data is transmitted by any m+i units to provide known algorithm of three-wire handshaking system for establishing communication over n, n+1, n+2 lines of interface trunk. EFFECT: widened functional capabilities of the device when establishing general interface trunk between removed objects. 3 cl, 8 dwg
