It is important to note that although the 1053 interface is designed according to IEEE
Std 488 and follows the recommendations of IEEE Std 728, absolute compatibility with
IEC or IEEE/ ANSI interfaces designed by other manufacturers cannot be unconditionally
guaranteed, since differences can occur within the limits of the specifications. Any prob-
lems encountered, however, will be of a software rather than a hardware nature. Where
compatibility is in doubt, contact your local Bruel
&
Kjrer representative for further
information.
5.2. IEEE FUNCTIONS IMPLEMENTED
The interface of the Type 1053 implements
.
the following functions as specified by the
IEEE standard. The Sections referred to are the relevant sections of the IEEE Std
488-1978 which specify the functions. The equivalent Clauses of IEC 625-1 are given iri
parentheses.

IEC standards.
5.3. ADDRESSING THE TYPE 1053
36
Each device in an IEEE interface bus system has at least one listener and I or talker
address depending on its function. When an interface controller contacts a device over
the IEEE interface, it sends a device address, which will contain the appropriate talker or
listener address. This address is in ISO 7-bit code (or equivalent ASCII), bit 8 being
unused for addressing. Table 5.1 gives a list of possible ADDRESS SWITCH settings with
the corresponding device address in the form of ASCII characters for the different ad-
dress modes.
