TEST VOLTAGES
The Model 14000 operating system is an EPIC
®
with CAN
Bus
®
technology. The CAN Bus system uses multiple nodes
that contain controllers. The controllers communicate with
node 1 (master) controller by sending data packets over a
two-wire bus line. The data packets are tagged with
addresses that identify system components of each node.
This section contains test voltages sorted by nodes. The
nodes are listed and identified in Figure 3-3
.
