The Prototyping Board comes with a 220 Ω termination resistor and two 681 Ω bias resis-
tors installed and enabled with jumpers across pins 1–2 and 5–6 on header JP5, 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 JP5.
B.4.7 RabbitNet Ports
The RJ-45 jack labeled RabbitNet is a clocked SPI RS-422 serial I/O expansion port for
use with RabbitNet peripheral boards. The RabbitNet jack does not support Ethernet con-
nections. Header JP3 must have pins 2–3 jumpered when using the RabbitNet port.
The RabbitNet port is enabled in software by setting PD2 = 1. Note that the RabbitNet
port and the J11 interface cannot be used simultaneously.
