Interfacing the XMP 2600

The GPIB interface

1Interfacing the

XMP 2600

The XMP 2600 has two types of interfaces used for remotely controlling it: a GPIB (IEEE 488) Interface and a Serial (RS232) Interface. The two interfaces differ only in the communication hardware and protocol. Input and Output Queues, Command and Query Parsing and Execution are identical no matter which interface is being used to remotely control the XMP 2600.

The XMP 2600 has two remote controlling modes. Unless otherwise required, the IEEE

488.2compatible mode should be used. The controlling mode in effect is DIP-Switch selected (at the rear panel – please refer to the user’s guide) and may be overridden by a Remote command.

The GPIB interface

The GPIB Interface is an IEEE 488.1 hardware interface with IEEE 488.2 capabilities. The capabilities of the GPIB Interface are summarized below:

SH1	Source handshake - FULL.
AH1	Acceptor handshake - FULL.
T6	Talker - basic, serial poll, unaddressed if MLA.
L3	Listener - basic, listen only, unaddressed if MTA.
SR1	Service request - FULL.
RL1	Remote local - FULL.
PP1/PP2	Parallel poll - remote and local configuration.
DC1	Device clear - FULL.
DT1	Device trigger - FULL.

The size of the Input and Output Queues is 256 Bytes.

The XMP 2600 uses an Input Queue rather than an Input Buffer (as required by IEEE 488.2). This enhancement practically prevents Lock- Ups.
