A.3 Jumper Configurations
Figure A-5 shows the header locations used to configure the various RCM5700/RCM6700
options via jumpers. Note that some early versions of the RCM5700 model sold in 2008 and 2009
do not have jumper locations JP2–JP5 — this does not affect the functionality of the RCM5700
model.
