Command Syntax Description
R# Read Last Readings R#chans Queries the last readings from the HLL Registers for specified
channels.
chans may be in two forms: chan (for a single channel where 1
< chan < max ) or first-last (for a range of channels
where 1 < first < last < max ),
where max = 128 for NetScan.
S
Set Real Time Clocks
Stime
Set the unit’s internal real-time clock where time is in the
standard time/date stamp format: HH:MM:SS:T
,
mm/dd/yy
where H is hours, MM is minutes, SS is seconds, T is tenths of a
second,
mm
is month,
dd
is day, and
yy
is year.
S? Query the internal real-time clock.
T Set Trigger
Configuration
Tstart,
stop,
re-arm,
sync
Configure an acquisition of scan data with the following
parameters:
start is the start event and stop is the stop event
re-arm determines if the unit should continue acquiring after the
first acquisition completes, where 1 is on and 0 is off.
sync determines if acquisition events should be synchronized
with the internal timebases, where 1 is on and 0 is off.
T?
Query the present trigger configuration
U User Status Ureq Request information about various internal conditions of the unit
where req refers to one of the following request types:
0 - Query and clear the Event Status Register (ESR)
1 - Query the Status Byte Register (STB)
2 - Query and clear Calibration Status Register (CSR)
3 - Query system settings
4 - Query current High/Low/Last registers
5
- Query and clear current High/Low/Last
6 - Query the Buffer Status String
7 - Query assigned alarm outputs
8 - Query configured channels
9 - Query digital inputs
10 - Query memory option (in Kbytes)
11 - Query all channels having programmed valid alarm setpoints
12
- Query last calibration time/date
13 - Query last scan read
14 - Query card IDs
15 - Query product information
16 - Query measuring parameters
17 - Query root mean square (RMS)
18 - Query acquisition states and various system flags
V Set User Terminator Vval Set the User Terminator value to any character whose numeric
value (ASCII value) val is in the range 0 to 255 .
V? Query the present user terminator value.
W# Set Average Weight W#wt In Normal mode, specify the number of samples to average for line
cycle integration or high-speed multi-channel use; where wt is
the average weight. Valid options for wt are: 1 , 2 , 4 , 8 , 16 ,
32 , 64 , 128 , and 256 (with 32 being the default value).
X Execute X Execute preceding command string.
Y Set Counts Ypre,post,
stop
When in Normal mode, set acquisition counts where pre is the
pre-trigger count,
post
is the post-trigger count and
stop
is
the post-stop count.
Select Blocks Y0,count,0 When in High-speed, single-channel mode (burst mode), set
count ; where count is the number of 256 sample blocks to be
collected
Y? Query current acquisition count selections.
