Module Technical Specifications
The connector on the FM-8Vi requires a male terminated RJ-21 cable. The FM-8Vi uses 8 of the 25 pairs
in the cable. Because the RJ-21 standard was established for telecommunications, one wire of each pair
is designated as the tip side and the other wire is designated as the ring side.
Table 111 lists the pin numbers on the connector, the color code for the wires, and the associated port
number for the wire pair.
