Procedure for Setting Up the EPROM
Procedure for Setting Up the EPROM
Use the following procedure to set up the EPROM after the EPROM or the
CPU board has been replaced.
• To set up the EPROM from the controller, use the following commands:
"MEM:DEL; Deletes everything in CMOS RAM memory.
"SYST:ERR?"
READ GPIB FOR ERROR Check the error queue (this can be used at any point
to read any error back).
"DIAG:MOD ""87130A""," Writes model number of your instrument.
"DIAG:SER ""US37349017"";" Writes the unique serial number of your instrument
(example is a typical serial number).
"ROUTE:DRIVE:ON(@X00:X30)" Enables channels* to be engaged.
"ROUTE:VERIFY:ON(@X00:X30)" Turns on sensing. (Can only be used with sensing
switches. Do not turn on for non-sensing or
non-Agilent switches.)
"MEM:SAVE;" Saves the above configuration to EPROM.
• Cycle power to the 87130A and check the EPROM:
"*IDN?"
READ GPIB Reads back the ID of the unit.
The screen should display:
"HEWLETT-PACKARD,87130A,USXXXXXXXX,950713" or something similar
"ROUTE:DRIVE:ON?(@X00,X01,
X02,X03,X04,X05,X06,X07,
X08,X09,X10,X11,X12,X13,
X14,X15,X16,X17,X18,X19,
X20,X21,X22,X23,X24,X25,
X26,X27,X28,X29,X30)"
Queries X00 through X30
READ GPIB Reads back 1’s and 0’s for each channel.
If VERIFY is ON, it will = 1; if OFF, it will = 0.
* Each channel has its own unique address. The switch driver begins numbering channels at 0 instead of
1. Switch one, wired to J1 on driver card 1, would have a channel address of 100 and so forth up to card
800 to 830.
