The Processor Terminator Card subsystem is designed for local monitoring or control applica- tions. It functions as a local peripheral to a Processor Terminator Card PDP 11. A maximum of - four IP112 subsystems can be connected to a single CPU. The IPV12 local I/O subsystem, similar to the IP112, interfaces to Q-bus PDP 11s including the - — Processor Terminator Card intelligent subsystems. IP112-AA/AD Industrial subsystems for local I/O monitoring and control by a UNIBUS PDP 11 host computer. Interfaces directly to the - Processor Terminator Card via software interface and operates under PDP 11 - control. A total of four subsystems can be connected to a UNIBUS based PDP 11 system. The Processor Terminator Card mounts in either a - 48.3 cm (19 in) rack or Processor Terminator Card cabinet and includes an H334 I/O subsystem chassis, power supply, an I/O control mod- ule (I0CM), and module expansion space. A driver and FORTRAN interface compatible with ISA61.1 are supplied as part of the RSX-11 operating systems. IP112 tasking may be programmed in Processor Terminator Card-11, FORTRAN IV, or Processor Terminator Card-77 operating under RSX-11M-PLUS, RSX-11M, or RSX-11S. Dimensions: 40 cm (15.5 in) by 48.3 cm (19 in) by 27.2 cm (10.69 in). Mounting: Mountable in Processor Terminator Card and Processor Terminator Card cabinets or NEMA enclosures.
