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.
