8.3 – Development Board Jumpers
Interface Header
The jumper block of J9-J18 configures the
signals between the CR822x and RJ-50
connector. This is done by shorting pins 1-2 or
2-3 on each jumper. Refer to the table below for
configuring these pins for each interface:

Serial Polarity and Boot Select Jumpers
J5 selects whether or not the primary RS232
data are inverted, and the combination of J6
and SW2 will select the boot mode the kit
comes up in. The RS232 data will be inverted
if J5 has pins 2-3 bridged. For non-inverted,
do not populate. Placing a jumper between 1-2
may damage the CR8200.
