Model 7090 Instruction Manual Operation 3-7
Scanning channels
There are a number of commands associated with scanning (see the Model 7001 or 7002
Instruction Manual). However, you can perform a simple scan using only the following
five commands:
*RST
:CONF:SCH ON
:TRIG:SEQ:COUN:AUT ON
:ROUT:SCAN <list>
:INIT
The *RST command selects the default scan configuration, while the second command
enables the single-channel mode. The third command automatically sets the channel count
to the number of channels in the scan list. The :ROUT:SCAN command programs the scan
list, and the :INIT command takes the mainframe out of the idle state and performs the
scan.
For example, send the following commands to scan through four channels of a card
installed in slot 1:
*RST
:CONF:SCH ON
:TRIG:SEQ:COUN:AUT ON
:ROUT:SCAN (@ 1!1:1!4)
:INIT
Multiple 7090 cards
Multiple 7090 cards can be programmed in the usual way. Single channel mode option
must be off if multiple cards are to have channel closures at the same time.
