Front Panel and Connector Pinouts

Front Panel

Table 1 shows the front panel connector and signal descriptions for the NI 5761. Refer to the

Specifications

section of this document for additional signal information.

Caution

To avoid permanent damage to the NI 5761, disconnect all signals connected to the NI 5761

before powering down the module, and only connect signals after the adapter module has been
powered on by the NI FlexRIO FPGA module.
