WSX-FE1-SC Cabling/Jumper Settings
The WSX-FE1-SC supports both twisted pair (120 Ohm) and coaxial (75 Ohm) cable types. The
default is 120 Ohm. You must set a pair of jumpers ( JP2 and JP4 ) on the back of the board to
correspond to the type of cable you are using. For more detailed information on the types of
cables to use with this module, see Appendix B, “Custom Cables.” The illustration below
shows the correct jumper positions.
♦ Note ♦
JP3 is reserved. Do not set a jumper across JP3 .
