RM-4339 Positions
The RM-4339 is divided into three positions A, B, and C. You can connect three separate
NI PXIe-4339 modules simultaneously to the RM-4339; one to each position. Each of the three
positions is independently controlled and powered by the NI PXIe-4339 to which it connects.
There are no constraints on how many or which positions are used. On the rear side of the
RM-4339, the three 96-pin DIN connectors are labeled A, B, and C. These correspond to the
three connector sets on the front of the RM-4339, which are also labeled A, B, and C. Connectors
within one of these positions connect to the same NI PXIe-4339 module. Figure 5 shows the
location of the connectors on the front and rear of the RM-4339.
