Table 1. Signal Descriptions
| Signal |
Reference |
Description |
|
AO <0,1>+, AO <0,1>- |
— |
Analog Output Channels—AO+ and AO- are the positive and negative outputs of the pseudodifferential or differential analog channel. |
|
PFI <0,1> |
GND |
Programmable Function Interface—A digital trigger input. |
|
GND |
— |
Chassis Ground—
Ground reference for the PFI inputs. On Mini-XLR connectors, GND also provides chassis grounding for AO. |
Table 2. LED State/Device Status
| LED |
LED Color |
Status |
| ACCESS |
Green |
The module is ready to be programmed. |
| Amber |
The module is being accessed. |
| Off |
The module is not yet functional, or has detected a problem with a PXI power rail. |
| AO 0, AO 1 |
Red |
An error has been detected on the channel or board. Possible errors include the following:
-
The board is overheated
-
The power supply is not at the proper voltage
-
A clocking error occurred (PLL fell out of lock or PXIeClk100 was not present when using the external timebase)
-
An external overvoltage or overcurrent was detected
-
An overload was detected
-
A streaming underflow was detected on the channel
-
Internal hardware failed (either due to software or hardware failure)
|
| Green |
The channel is actively generating a signal. |
| Amber |
The channel is waiting for a trigger to start generating. |
| Green/Amber (Alternating Flashing) |
The reference clock source is changing to onboard or PXIeClk100. |
