This appendix describes how to customize your SCXI-1127 module for
current-loop receiving. The SCXI-1127 modules have plated through holes
for transforming individual channels to current-to-voltage converters.
National Instruments offers a process-current pack of four 249 Ω, 0.1%,
5 ppm, 0.25 W resistors. The reference designator format for the
current-loop resistors is such that input channel x corresponds to the
resistor reference designator RCLx. For example, the resistor pad for
channel 14 is RCL14.
Before installing your module in the SCXI chassis, you must install the
resistors by performing the following steps while referring to Figure C-1:
