The chart below shows the name and default setting of each switch.

Switch # Switch Name Default Setting

I_FLAG OFF

PFI5_OUT ON

OPA_EN_H OFF

DIO7_OUT ON

SENSOR_EXC ON

EXC_BYPASS OFF

With the switches in their default positions, the DAQ Expansion Pod

is conﬁgured as follows:

The current limit monitoring of the Sensor Excitation Output is

disabled.

PFI 5 is connected directly to the 50-pin D connector.

The Sensor Excitation is enabled continuously.

DIO 7 may be used for standard digital input and output.

The Sensor Excitation is output rather than the Analog Out 0

signal.

Conﬁguring Switches

This section shows you how to reconﬁgure the switches of the DAQ

Extension Pod. Speciﬁcally, it shows you how to:

Continuously enable the Sensor Excitation Output

Use DIO7 to enable/disable the Sensor Excitation Output

Output the Analog Output 0 rather than the Sensor Excitation

Enable current limit monitoring

Disable current limit monitoring

Continuously enable the Sensor Excitation Output

By setting the conﬁguration switches as shown in the following

table, the Sensor Excitation is continuously output at the voltage set

by Analog Out 0. The Sensor Excitation Output uses Pin 16 on the

50-pin connector.

To continuously enable the Sensor Excitation Output, conﬁgure the

switches below to the following settings:
