8 JUMPER LOCATIONS ON THE BOARD
Jumper locations on the board
The figure shows the location of all jumper blocks on the MSM586SEN/SEV board. The numbers shown in
this figure are silk screened on the board so that the pins can easily be located. This chapter refers to the
individual pin for these jumpers. The default jumper settings are indicated with bold letters.
Be careful when you change some jumpers. Some jumpers are soldering bridges, you need a miniature sol-
dering station with vacuum pump.
