ControlWave Express Instruction Manual (CI-ControlWave Express)
Revised Mar-2011 Installation 2-21
2.3.7 Connections to the Ethernet Port on the CPU/System
Controller Board
Caution
The RJ45 Ethernet port is connector (J1) located on the CPU/System
Controller board. The board also has one RJ45 port (J2) for the optional
Display/Keypad. Never
connect Ethernet to J2 (the Display/Keypad port)
or damage will result.
The 33MHz ControlWave Express can support one Ethernet port. This
port uses a 10/100Base-T RJ-45 modular connector (J1) that provides a
shielded twisted pair interface to an Ethernet hub.
A typical Ethernet hub provides eight 10/100Base-T RJ-45 ports (with
port 8 having the capability to link either to another hub or to an
Ethernet communications port). Both ends of the Ethernet twisted pair
cable are equipped with modular RJ-45 connectors.

These cables have a one-to-one wiring configuration as shown in
Figure 2-11. Table 2-11 provides the assignment and definitions of the
8-pin 10/100Base-T connectors.
