C-Bus Network Interface Installation Instructions

The PC must be configured with an IP address; either static or

dynamic/automatic (if a DHCP server is connected). If you are using a

network/Internet firewall, you may need to disable it temporarily.

If you use the telnet or web browser configuration method, you must first

use your operating system's ARP utility to assign the CNI with a temporary

IP address. (An exception to this is if the CNI is already set to a known IP

address which is compatible with the PC's IP address and is not used by

another device on the network).

Using the ARP Utility (before using telnet or a web browser)

1) Note the IP address of your PC. In Windows you can do this by

entering ipconfig at a command prompt.

2) Choose an IP address to temporarily use with the CNI (it need not be

the permanent address you want to assign to the CNI). The address

must be compatible with the IP address of your PC, and not used by

any other Ethernet device connected to the same network. For

example, if your PC is set to 192.168.0.5, set the CNI to an IP address

from 192.168.0.1 to 192.168.0.4 or 192.168.0.6 to 192.168.0.254.

If the IP address of your PC is set automatically by a DHCP server, it is

safest to choose an IP address which is much higher. For example, if

your PC is set to 192.168.0.5, use something like 192.168.0.200 for

the CNI.

3) Start a command prompt/terminal session. In Windows this is found

in start/All Programs/Accessories/. If you are using Linux, you will

need to run as root.

4) Type arp -s followed by the temporary IP address you are using

with the CNI, followed by a space, then the CNI's MAC address. The

MAC address is printed on a label attached to the side of the CNI. The

MAC address is a set of six hexadecimal number pairs, separated by a

dash or colon.

For example, to use an IP address of 192.168.0.12 on a CNI with a

MAC address of 00-20-4A-2C-18-04, type:

arp -s 192.168.0.12 00-20-4a-2c-18-04 (Windows platform)

arp -s 192.168.0.12 00:20:4a:2c:18:04 (Linux platform).

After pressing Enter, this causes the CNI to temporarily set its IP

address to the one specified. If configuration is not completed, the

unit will revert to its previous setting when power is removed.
