The Ethernet connection must have an IP Address that is set manually in the
IP Address
field or obtained
automatically from the router connected to the logger using the Use DHCP option (dynamic address)
found in the Logger Network Setup dialog box accessed via the
Setup
button. Both options have
advantages.
NOTE:
A Static IP address of 10.75.75.63 is assigned in the factory to all Ethernet Power Patrol meters.
Static Connection
: If you know an IP address that is not being used by another device on the
network, enter that address into the
IP Address:
field. This may require permission from a
network administrator. With a static IP address it is easy to connect to meter as there is no
doubt about what IP address to use.
Dynamic Connection
: If you want the router to assign an IP address to the meter automatically,
select Use DHCP. This may avoid the need of a network administrator as the router will assign an
IP address that does not conflict with any other devices on the network. A disadvantage of the
DHCP option is that the “lease” of the IP address may expire after a period of time and the
router could assign a different IP address. A new IP address means that HeadStart cannot
connect to the meter until the new IP address has been entered. (See below.)
An additional option is to set the Power Patrol meter to DHCP and go to the router and assign a specific
IP address to the MAC address that corresponds to the logger. In this way, if the lease does expire, the
router will always assign the same IP number back to the logger. This option may also require a network
administrator.
The
Scan Network
button scans the network for possible meters and displays them in the Logger
Selection dialog box. Look for the serial number on the meter (found on the back of the meter) to
determine which connection point is yours.
