The RCM3700 Prototyping Board comes with a 220  termination resistor and two 681 
bias resistors installed and enabled with jumpers across pins 1–2 and 5–6 on header JP1,
as shown in Figure B-9.
For best performance, the termination resistors in a multidrop network should be enabled
only on the end nodes of the network, but not on the intervening nodes. Jumpers on boards
whose termination resistors are not enabled may be stored across pins 1–3 and 4–6 of
header JP1.
