This Technical Information Series No.2 (2nd edition) provides detailed specifications for linking the HITACHI-505 analog computer to a digital computer via a hybrid interface. It covers interface signal requirements, input/output channel configurations, multiplexer and A-D converter performance specs (±10V range, 0.1% accuracy, sign+binary 10-bit output code), and the serial BCD protocol for remotely setting servo-set potentiometers (SP) and servo-set function generators (SFG) from the digital side. Connector pin-out tables and system block diagrams for the hybrid linkage are included.
