Product Description

The IEQ11 Replacement Module – M8634 (DCQ-3100) is a DMA controller that interfaces a Q-bus system to two independent channels that are compatible with both the IEC and IEEE instrument buses. The instrument buses conform to both the European Standard IEC 625-1 and the U. S. Standard IEEE 488.1-1987. Each instrument bus can have up to fifteen devices, including the DCQ-3100, in a sequential configuration.

Each independent channel of the DCQ-3100 provides system controller, controller-in-charge, talker, and listener capabilities. Termination of data transfers are by E.O.I., byte count, or by match characters.

The DCQ-3100 is software and hardware compatible with Digital’s IEQ11-A Q-bus controller and can be used as a direct replacement.

The DCQ-3100 is a quad-width controller that supports both 18-bit and 22-bit Q-bus operation and can be installed into a variety of Digital systems including MicroPDP-11, MicroVAX II and MicroVAX III.

Installs in MicroPDP-11 and MicroVAX II systems and can be used with Digital cables and panels or with Logical’s IEC and IEEE panels.
