If you are using the SCXI-1200 in an SCXI-2000 chassis or with an
SCXI-2400 module with RS-232/RS-485 communications, you do not
need to be concerned with parallel port addresses and interrupts.
Module Configuration
The SCXI-1200 is software calibrated and software configurable. The
SCXI-1200 has one reserved jumper that selects the grounding scheme
for the SCXIbus guard.
Analog I/O Configuration
The SCXI-1200 is shipped from the factory with the following
configuration:
•
RSE input mode
•
±5 V analog input range (bipolar)
•
±5 V analog output range (bipolar)
Table 3-38 lists all the available analog I/O configurations for the
SCXI-1200 and shows the factory settings.
Both the analog input and analog output circuits are software configurable.
