The scb-1020 supports asynchronous bit and bytle oriented protocols. The synchronous protocols may be applied to monosync and bisync as well as hdlc and sdlc opertion. The rs-232 signals are interfaced to external devive via a d-25 connectorwhich provides shielding against environmental noise.Other characteristics of the scb-1020 include jumper selectable dma request (channels 1 &3) and jumper selectable interrupt requests (irq2-irq70).
