Installing SCPI Device Drivers
Contents
1. Install from a BASIC system over GPIB Install from an MS DOS system over RS 232 Install from IBASIC over GPIB Because the installation programs re configure memory you must download all of your device drivers at the same time If you already have device drivers on your system and wish to add another driver you must delete the existing drivers and reinstall them with the new driver If you start an installation program and it detects existing drivers or detects memory allocations that it will destroy it will issue a warning with appropriate instructions and abort These procedures assume that you are installing a single device driver If you have multiple device drivers you should copy all of the installation and driver files to a single hard disk directory and run the installation program from that directory This installation method requires you to have a system with BASIC 5 0 or later and a GPIB IEEE 488 2 communications port Set the Sys Control Talk Listen switch on your Agilent E1300 E1301 Mainframe to Talk Listen or the GPIB Controller switch on your Agilent E1405 E1406 Command Module to zero or OFF no setup is required for the Agilent E1306 Command Module E1405A E1406A N Da g Y POS Oy g PN e SWITCH MUST BE SWITCH MUST BE SET TO TALK LISTEN Figure 3 Setting GPIB Controller Mode OFF 10 Installing SCPI Device Drivers Procedure Installing Device Drivers from MS DO2. see Figure 3 No specific setup is necessary for the Agilent E1306 Command Module On most computers a program will be required for the actual installation process Since driver files contain the command to start the installation plus the data to transfer this program just needs to set up the appropriate memory area and transfer the driver files into it Send a RST command and a CLS command to the Command Module to put it in a known state before beginning your installation N Use the DIAG DRAM commands to create the driver memory area if you are installing into Driver RAM or the DIAG FROM commands if you are installing into Flash ROM If you are installing to Driver RAM and wish to allocate NRAM or RDISK you should issue the appropriate commands at this time io If you are installing to Driver RAM issue a DIAG BOOT command to reboot the Command Module and allocate the specified memory 4 Transfer the device driver file to the Command Module This file contains the appropriate commands to accomplish the installation Nn Send the SCPI query SYST ERR to make sure that there were no errors during the installation 6 Reboot your system if you installed to DRAM send DIAG BOOT or send the DIAG DRIV INST command and switch the RUN LOAD switch to the RUN position if you installed to Flash ROM 7 Check to make sure that your drivers have been loaded into memory by sending the SCPI command DIAG DRIV LIST RAM o
