Reconfiguring The Remote GUI
If the IP addresses of the FM‑531HD have been changed from those configured
in the remote GUI a few pages ago it will be necessary to go back into the GUI con-
figuration and change the IP address for the FM‑531HD device that was originally
configured for the remote GUI. Here is how to do that…
Right click in the controls area of the remote GUI to activate the drop down menu
and select the Devices option under Hardware. When the Edit Device dialog opens
highlight the FM‑531HD device that was created earlier and click on
Edit. Then modify
the IP address so that it perfectly matches the new hardware IP address just given to
the FM‑531HD hardware and then click
OK.
Assuming that a good network path exists between the host PC (don’t forget to
change its address too if the IP address subnet has changed!) the GUI should be able
to go online to the FM‑531HD by clicking on the
Online button at the top of the GUI.
When the status indicates Online the GUI is communicating with the FM‑531HD.
Connecting Directly Without a LAN
You can work without a LAN by connecting the FM‑531HD and the PC Ethernet
ports together with a standard Ethernet cable – either a straight through or crossover
cable may be used – the FM‑531HD’s Ethernet interface ports are Auto MDIX.
NOTE:
The controlling PC and FM‑531HD’s network settings must be configured
to place them both on the same subnet! Although the network subnet can be any one
that is valid, both local and remote devices must be on the same subnet in order to
communicate.
Example:
If the FM‑531HD is using the 192.168.1.x address range and a laptop is using the
172.68.122.x address range the laptop
will not
be able to communicate with FM‑531HD.
The laptop will need an IP address configuration that puts it on the same 192.168.1.x
network subnet as the FM‑531HD.
About DHCP and FM-531HD
The FM‑531HD does not utilize nor support Dynamic Host Configuration Proto
-
col (DHCP, or automatically assigned network addressing) – and needs to be assigned
“STATIC” network‑unique IP addresses.
FM-531HD’s Ethernet Ports and Network Protocols
The FM‑531HD uses both TCP and UDP protocols to communicate with the remote
GUI. The TCP protocol is used between the GUI to the FM‑531HD for control func
-
tions. TCP’s high reliability (due to handshaking) ensures that control changes sent to
the The FM‑531HD by the GUI will be received
without errors.
Metering data is not at all critical, and only the differences between past and next
meter values are sent. Therefore a “no‑handshaking” protocol, UDP, is used to send
metering and other real time data back to the GUI. Dropped or corrupted packets will
have little visual effect on the metering and analysis displays, and the lack of (or no
need for) handshaking
drastically reduces the amount of network bandwidth that is
required in order to run the GUI’s remote meters and analysis displays.
