Setting/Changing MAC Address
CAUTION:
Be sure you understand the purpose of the MAC Address before using
this procedure. Setting the MAC Address incorrectly will affect data
transmission. Contact your customer service representative if you have
questions.
Usually, the MAC address automatically acquires the MAC level address of the
host PC. This address is required by the RTU to communicate with the central
office. Generally, users should not change this address. However, if the address
acquired is not correct or if you are changing Ethernet cards on your PC, you will
need to change the MAC address accordingly.
" Procedure
To access the MAC Address window:
1. Select Advanced Hardware
Setup from the Configuration
menu.
2. Select MAC Address to display
the MAC Address window.
To change an incorrect address:
1. Get MAC address from the Ethernet
card.
2. Use your keyboard to enter the new
MAC address in the field provided.
Be sure to use the correct address
format. (The address must be entered
in hexadecimal format with no spaces or dashes between the values.)
3. Click on OK to accept the MAC address change. Using the OK operation
disables automatic mode. This means that the system will not acquire or set
the MAC address automatically again until the Reset operation is used.
To acquire the MAC address automatically (return to automatic mode after the
MAC address was manually set):
H Click on Reset.
To close the window without changing the address:
H Click on Cancel.
