6.Input / Output data

BCD and binary parallel signal equipment can be easily transfer data to PC via GP-IB

interface by adding address decoder, data latch circuit and gate circuit. It is necessary to use

the signal of ZS-6123BP data buses D0 to D7, address bus A0 to A7, WR, RD, ADR-CR,

ADR-LF in this case.

6.1 Example for expanding output data.

Chart 6.1

Note) In this circuit example, the number of output data can be expanded up to 8 bytes by

adding a latch circuit LS273.
