16 Getting Started Chapter 1
Example: Closing
Relays (BASIC)
This example assumes a PC running BASIC and a GPIB interface. The
program closes row 03, column 12 of an E1465A 16x16 matrix module at
logical address 120 (secondary address = 120/8 = 15) and queries the
result. The result is returned to the controller and displayed (1 = relay closed,
0 = relay open). See Chapter 4 for information on the SCPI commands.
10 OUTPUT 70915; "*RST"
! Resets the module
20 OUTPUT 70915; "CLOS (@10312)"
! Closes row 03, column 12 on
module number 1
30 OUTPUT 70915; "CLOS? (@10312)"
! Query channel 10312
40 ENTER 70915; Value
! Enter result into variable Value
50 PRINT Value
! Print results (should print "1"
to indicate that the channel is
closed)
60 END
! Terminate program
