Connecting the Ethernet Port:
The ethernet port is connected to the desired network using a twisted pair ethernet cable. To
connect to a 10BaseT HUB use a straight through (normal) patch lead.
Operation of LEDs:
Each port has a Green LED on the output port and a Yellow LED on the input port. The green
led for each port flashes when data is transmitted. Yellow means that the input port is not
receiving data correctly, or there has been supervision failure on this port.
Operation of Relay:
There is a supervision relay on each board which is reserved for future use.
Configuration of CCU/E-HUB:
Each CCU node must have a unique address between 1 and 65534. Addresses 0, 255 and
65535 are reserved and CANNOT BE USED.
The CCU Node address on the CCU/E board must be set by software as there are no address
jumpers as on most other CCUs.
The CCU node address and all other configuration parameters can be changed using the
CCUNET program.
Reprogramming Procedure
In the event the CCU has to be reprogrammed please follow the instructions below.
1. Unzip the supplied files into the same directory as ccunet.exe.
Overwrite any files already there.
2. Connect the CCU into the network. Make sure it has been given a unique address.
3. Run ccunet.exe. This is a windows program and must be run on an XL Graphics
computer connected to the ccunet. XL Graphics MUST be shutdown before running this
program.
4. The Comms button allows you to change the COM port to which the ccunet is
connected.
5. Press firmware button. A list of all the CCUs connected to the network will display. The
new CCU should appear in this list.
6. Left click in the program column. A green dot will show.
7. Press Program. When the prompt appears verify the address is that of the board you
want to program. If so press Yes.
8. Wait until Success message or timeout message.
9. Press Close.
10. Choose Main/Clear List then press scan button.
11. Make sure CCU is in new list.
