The Digital488/32/OEM is a 4 in. by 4 in., 32 I/O line interface board for transferring data between the IEEE 488 (GBIP, HP-IP) bus and devices equipped with up to 32-bit wide digital ports. The Digital488/32/OEM’s 32 TTL-level digital I/O lines are programmable in 4-bit ports as either inputs or outputs. When addressed to talk, the Digital488/32/OEM will output data from all thirty-two bits or a selected 8 bit port. The board also offers six handshake lines for implementing clear, data strobe, external data ready, inhibit, trigger, and SRQ functions. Its firmware includes a complete command set for facilitating the implementation of all its functions. This command set is identical to that employed by the other board-level and external interfaces in IOtech’s industry-standard Digital488 family, facilitating quick prototyping and making the Digital488/32/OEM compatible with other Digital488 family units.
