|
|
|
|
|
CRIO-WR is a standalone White Rabbit node implementation in the form
|
|
|
factor of a National Instruments CompactRIO module.
|
|
|
factor of a National Instruments CompactRIO module. The module complies
|
|
|
with NI CompactRIO specification (exceptions see below).
|
|
|
|
|
|
The module complies with the cRIO spec, *except for current consumption
|
|
|
and dissipation power*. The connector at the front panel provides 10
|
|
|
user I/O, connected directly to the FPGA to be flexible (input / output,
|
|
|
LVDS / CMOS, SERDES etc.).
