‘To get one display value back from the SC-5500, issue the following commands
r$ = SPACE$(12) ‘Set up display readback string for 12
‘characters in 4 1/2 digit mode.Data format returned is
‘terminated by <CR><LF>
Receive (0, 10, r$, NullEND) 'Format is:0 = IEEE Interface board number
‘10 = Default address of the SC-5500, r$ = String variable
‘NullEND = Terminator
‘The SC-5500 will execute the Receive command by placing one display value into its buffer. The buffer is then swept and
‘the data sitting there is placed into the string variable. This one command will perform both tasks. The O0X command is
‘only an RS-232 command. It should never be used for the IEEE interface.

‘Now set up AutoRange:
CALL IBCMD(0, scwrite$) ‘Send MTA/MLA
CALL IBWRT(0, "A0X") ‘Turn on Autorange
SLEEP 5
CALL IBCMD(0, scwrite$) ‘Send MTA/MLA
CALL IBWRT(0, "A1X") ‘Turn off Autorange
‘Set up ReadBack:
CALL IBCMD(0, scread$) ‘Send MTA/MLA
CALL IBRD(0, r$) ‘Receive into program the display value
