ControlWave Gas Flow Computer (GFC Plus) Instruction Manual (CI-ControlWave GFC Plus)
Revised Feb-2013 Installation 2-33
2.9.3 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 GFC Plus 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.
