SDSACT
Purpose
Read or set current SDS status. This is equivalent to use of the [SDS] key from the RPM4-
AD front panel.
Command
Query
“SDSACT
state
”
“SDSACT”
Classic “SDSACT=
state
”
“SDSACT”
Default “SDSACT=1”
Arguments ”state”
:
‘0’ OPEN the SDS system as appropriate for the current measurement
mode and active Q-RPT, .
‘1’ to CLOSE the SDS system on both Q-RPTs.
Remarks
This command can be used to select one Q-RPT at a time, ensuring that the “inactive” Q-RPT
SDS is closed. If a Q-RPT’s SDS is full time “OFF”, then it is not be affected by this
command. The status of the active Q-RPT’s SDS system is replied. If the RPM4-AD is in
differential mode then this command opens or close both the Hi and Lo SDS at the same
time, unless the SDS is full time “off”. If the HL Q-RPT is active, then the state of the SDS is
set as appropriate for the current measurement mode.

SDSAUTO
Purpose
Read or set the automatic full time ON/OFF status of the SDS system. This is equivalent to
use of the SDS full time ON/OFF function from the RPM4-AD front panel.
Command
Query
“SDSAUTO
on
”

on
”
“SDSAUTO”
Default “SDSAUTO
n
=1”
Arguments ”
on
”
:
‘0’ to turn the SDS system OFF.
‘1’ to turn the SDS system ON
Remarks
Turning an SDS system to full time “OFF” or “ON” affects how the remote command
“SDSACT” and the front panel SDS button can affect each Q-RPT’s SDS system. Turning
SDS to full time ”OFF” opens the SDS valves for both Q-RPTs or as appropriate for the
current measurement mode if the HL Q-RPT is active.
