Using and Troubleshooting the GPIB-VXI/C

Programming with the GPIB-VXI/C

This section describes some of the most common commands that you can issue to the GPIB-VXI/C. The commands can be issued through the serial interface or using IEEE 488 commands. The RM Information Queries will be covered followed by a description of some of the most common I/O commands.

RM Information Queries
The RM Information Queries return information about the known system. If the GPIB-VXI/C is the system RM (Resource Manager), it can access information about the entire system. If it is not the RM, it has information only about itself and its immediate Servants.

The RM Information Queries covered in this section are the following:

• A24MemMap? and A32MemMap?
  
  
• Laddrs?
  
  
• NumLaddrs?
  
  
• RmEntry?
  
  
• ConsMode
  
  

This section explains how to issue these commands using IEEE 488 commands. Therefore, if you are using any of our GPIB drivers, you can use the GPIB interactive control (IBIC) program. You have to open a session to the GPIB-VXI/C to issue the RM Information Queries. Below is an example of how to open a session to GPIB-VXI/C, where its primary address is 1 and secondary address is 0 (96 in IBIC).

The ibsic command will clear the GPIB bus. The ibdev command will open a session to the GPIB-VXI/C. Now you are ready to issue the RM Information Queries.
