The  Input/Output  Settings  Follow  Preset  Takes  choice  allows  the  FM‑531HD  to 

modify its input and output gain settings whenever presets are recalled. Input and output 

gain settings are always stored with the presets when processing values are stored, but 

those settings will be ignored upon preset recall when the Input/Output Settings Follow 

Preset Takes check box is unchecked. 

Metering Data Over TCP/IP

The FM‑531HD utilizes the UDP protocol by default for transmitting metering data 

to the remote GUI (TCP with its guaranteed packet delivery is always used for control).

In some instances UDP packets are blocked by Internet Service Providers, and when 

this occurs the GUI can successfully connect to the FM‑531HD but there is no visible 

metering data. Unless one can successfully convince the ISP to allow unsolicited UDP 

traffic on their network (doubtful) the solution is to utilize VPN Tunneling (which en

capsulates all packets into TCP) or simply switch the FM‑531HD and its GUI to using 

the TCP protocol for metering. When the Metering Data over TCP/IP box is checked the 

TCP protocol is used for transmitting metering data instead of UDP. 

Remote Login

When  Remote Login is clicked, a password 

prompt box will open as shown 

on the right. 

Remote Login is for password 

restricting Pro GUI access to 

an FM‑531HD over Ethernet. 

When a GUI TCP connec‑

tion session is initiated, the 

FM‑531HD accepts the con‑

nection and then asks the remote Pro GUI for a 

password. 

If the remote GUI cannot provide the correct password, then a dialog box will pop up 

asking the user to enter the correct password.

Until the login password can be verified the FM‑531HD will not send its current settings 

to the remote GUI nor will it accept any changes from the connecting GUI.

The dialog box show above also allows a user to change the login password if one has
