4.1 IEEE 488 Interface
4.1.1 IEEE 488.1 Interface functions supported
The IEEE 488.1 Interface functions supported by the DLS 50 are as follows :
SH1 Source handshake - full capability
AH1 Acceptor handshake - full capability
T5 Basic talker - serial poll, untalk on MLA
L3 Basic listener - unlisten on MTA
SR1 Service request - full
DC1 Device clear - full
C4 Respond to SRQ
E1 Open Collector drivers
RL1 Remote Local - full
These represent the minimum required to implement the IEEE 488.2 standard.
4.1.2 IEEE 488 Address
The IEEE 488 address of the DLS 50 can be set to any of the valid value as defined in
the IEEE 488.1 standard, which can be from 0 to 30. The address can be change by
using the front panel (see section 3.4) or remotely (see section 4.7.2).
4.1.3 The SRQ Line
The SRQ line, as defined by the IEEE 488.1 standard, is raised when the DLS 50 is
requesting service. Here are some examples of services that could raise SRQ:
• A message is available in the output buffer
• An error occurred
• All pending operations are completed
• The power was just turned on
