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

.
