You can expand the number of analog channels beyond two with additional NI PXI/PXIe-2515 (NI 2515) modules. Each additional NI 2515 module provides two additional analog channels. The number of digital lines does not change when you add analog channels.

Analog Channel Expansion on the NI 2515

Complete the following steps to expand the number of analog channels.

  1. Connect the first NI 2515 to the NI PXI-654x or 655x HSDIO module as described in NI PXI/PXIe-2515 Intended Use.
  2. For each additional NI 2515 module, connect the "IO NI 2515" side of an additional SCH68-C68-D5 cable to the "HSDIO" connector of an additional module.
    Note Note  You must use the SCH68-C68-D5 cable. The pinouts are different from other SCH68 cables.
  3. Connect the other end of the SCH68-C68-D5 cable to the "DUT" connector of the previous module.

Note   HSDIO signal quality is incrementally reduced by each additional NI 2515 module.
