devices. Installed devices appear under the name of their associated chassis. Note If you are using the NI 5690 with the LabVIEW Real-Time Module, expand Remote Systems. Find your target IP address or name, expand it, and then expand Devices and Interfaces. 3. Expand your Chassis tree item. MAX lists all devices installed in the chassis. Your default device names may vary. Note If you do not see your hardware listed, press to refresh the list of installed devices. If the device is still not li ...

Connector Access Function CH 1 IN Input CH 1 IN and CH 1 OUT each function as a programmable amplifier with switchable main and direct paths. The main path offers fixed gain amplification preceded by a step attenuator that is adjustable in 1 dB nominal steps.1 The direct path bypasses the programmable circuitry and routes the signal directly to the output. The direct path passes DC level to output, whereas the main path is AC-coupled. CH 1 OUT Output Table 2. NI 5690 Front Panel LED Indicators LED Indications ACCESS Indicates the basic hardwa ...

Why Is the ACCESS LED Off When the Chassis is On? The LEDs may not illuminate until the device has been configured in MAX. Before proceeding, verify that the NI 5690 appears in MAX. If the ACCESS LED fails to illuminate after you power on the chassis, a problem may exist with the chassis power rails, a hardware module, or the LED. Caution Apply external signals only while the NI 5690 is powered on. Applying external signals while the device is powered off may cause damage. 1. Disconnect any signals from the module front panels. 2. Power off the chassis. 3. Remo ...
