- High-speed Z-300 CPU execution with 7.5 K-word program capacity
- Integrated timing, counting, clock, data-memory, and symbol resources
- Selectable RS-232C or RS-422A host communication with board expansion
Z-312J provides the processing and memory resources for a SHARP J-board controller assembly.
It coordinates local program execution with installed I/O and communication boards while retaining a built-in clock and a selectable upper-level serial interface.
A controlled exchange depends on the correct program and ROM, switch position, supply quality, expansion load, communication standard, connector mapping, and post-installation functional test.
Availability, condition, price, and shipping time for Z-312J are confirmed during quotation.
