Explanation
To use the GP-IB interface, you must set the GP-IB address and command type.
GP-IB Address
Set the GP-IB address in the following range. Assign a unique address.
0 to 30
Command Type
The 2553A is compatible with the remote control commands of its predecessor model, the 2553. Select
the command type depending on your situation.
• NORM: Normal commands. These commands comply with IEEE488.2 (see chapter 11).
• COMP: 2553 compatible commands.
Notes on Using Existing Programs
To use an existing 2553 program on the 2553A, note the following points.
• Insert a wait time of 1 second in operations that change the output. If you do not, the program
may not work properly.
• The 2553A stores the polarity and output setting separately for the voltage, current, and
temperature. The 2553 stores only a single set of polarity and output setting. As such, to use an
existing 2553 program, you need to change the range and then specify the polarity and output
setting for the voltage, current, and temperature so that they are congruent with the 2553A
settings.
For details on COMP commands, see the 2553 user’s manual.
Note
• Only use a single communication interface: USB, GP-IB, or Ethernet. If you send commands
simultaneously from more than one communication interface, the 2553A will not execute the commands
properly.
• When the controller is communicating with the 2553A or with other devices through GP-IB, do not change
the address.
• Each device that is connected in a GP-IB system has its own unique address. This address is used to
distinguish between different devices. Therefore, you must assign a unique address to the 2553A when
connecting it to a PC or other device.
• The command type setting takes effect when you turn the 2553A off and then back on. If you select
COMP, the 2553A will not accept standard commands nor communicate using the USB or LAN interface.
