For more information about how to further configure the SCXI-1125, or how to use
LabVIEW to configure the module and take measurements, refer to Chapter 4,
Verifying the Signal in Traditional NI-DAQ (Legacy)
This section discusses how to verify the signal in Traditional NI-DAQ
(Legacy) using channel strings and virtual channels.
Verifying the Signal Using Channel Strings
The format of the channel string is as follows:
ob
x
!
sc
y
!
md
z
!
channel
where
•
ob
x
is the onboard E Series DAQ device channel, with
x
representing
a particular channel where the multiplexed channels are sent. This
value is 0 for E Series DAQ device channel 0 in a single-chassis
system. In a multichassis or remote chassis system, the E Series DAQ
device channel
x
corresponds to chassis number
n
– 1, where E Series
DAQ device channel
x
is used for scanning the
n
th chassis in the
system.
•
sc
y
is the SCXI chassis ID, where
y
is the number you chose when
configuring the chassis.
•
md
z
is the slot position where the module is located, with
z
being the
particular slot number. The slots in a chassis are numbered from left to
right, starting with 1.
•
channel
is the channel that is sampled from module
z
.
