Remote Communications Interfaces - Tektronix Keithley 2651A Reference Manual

Section 2: General operation

Remote communications interfaces

You can choose from one of several communication interfaces to send commands to and receive
responses from the Model 2651A.
You can control the Model 2651A from only one communications interface at a time. The first
interface on which the instrument receives a message takes control of the instrument. If another
interface sends a message, that interface can take control of the instrument. You may need to enter a
password to change the interface, depending on the setting of interface access.
The Model 2651A automatically detects the type of communications interface (LAN, USB, GPIB, or
RS-232) when you connect to the respective port on the rear panel of the instrument. In most cases,
you do not need to configure anything on the instrument. In addition, you do not need to reboot if you
change the type of interface that is connected.
Supported remote interfaces
The Model 2651A supports the following remote interfaces:
•
GPIB. General purpose interface bus is an IEEE-488 instrumentation data bus.
•
LAN. Local area network (LAN) communications provide the flexibility to build scalable and
functional test or data acquisition systems with a large degree of flexibility.
•
RS-232
The Model 2651A can be controlled from only one communication interface at a time. The first
interface from which it receives a message takes control of the instrument. It ignores the other
interfaces until the instrument is returned to local operation.
