SEND_MESSAGE “command”
This command is used to send NIM-488 commands to the MCS. It can be used to perform
any desired MCS operations. The text must be in the syntax expected by the MCS. If the
response from the MCS does not end with a command-accepted message, this command will
exit with error. Specific MCS commands and syntax are described in Appendix D.
Following is an example of using this command to set the date in the Easy-MCS to March 3,
2000:

SET_MCS 1
STOP
SEND_MESSAGE “SET_DATE 3,3,00"

SET_DISCRIMINATOR_EDGE <n>
If <n> is 0, the discriminator is set to rising-edge triggered. If <n> is not zero, the discrimi-
nator is set to falling-edge triggered. This command performs the same function as the
Rising/Falling radio buttons on the Input Control dialog (Acquire/Input Control...). This
command fails if the buffer is selected.
SET_DISCRIMINATOR <f>
Sets the discriminator level to <f> volts. The value of <f> may be a floating-point number
between
!
1.6 V and +3.0 V. This command performs the same function as the Discrimi-
nator slide bar on the Input Control dialog (Acquire/Input Control...). This command fails
if the buffer is selected.
SET_DWELL_ETHLD <f >
Sets the external dwell threshold. F can be a floating-point number between
!
1.6 V and
3.0 V.
SET_DWELL_EXTERNAL
Sets the dwell time to external. The SET_DWELL_TIME command switches the MCS from
external to internal dwell. This command is only valid when an MCS is selected and is not
acquiring data.
SET_DWELL_TIME <f>
Sets the dwell time to <f> seconds and selects internal dwell time. The value of <f> is a
floating-point number that may take on any value from 5 × 10
!9
to 65535. If an invalid dwell
time is specified, the MCS will roundoff the value to the closest legal value. This command
fails if the buffer is selected or the MCS is acquiring data.
