Bus lines
●
Data bus with 8 lines D0 to D7:
The transmission is bit-parallel and byte-serial in the ASCII/ISO code. D0 is the least
significant bit, D7 the most significant bit.
●
Control bus with five lines:
IFC (Interface Clear): active LOW resets the interfaces of the instruments connected
to the default setting.
ATN (Attention): active LOW signals the transmission of interface messages, inactive
HIGH signals the transmission of device messages.
