3.1 Identifying the Master AquaTrend
Every AquaTrend
®
Interface Network System requires a network manager
to perform network operations, such as adding or removing devices.
The AquaTrend and AquaTrend with SOM can perform network
management functions when set to Master AquaTrend status through the
AquaTrend software; however, only one Master AquaTrend can be present on
the network at a time. All other AquaTrends must be set to Remote AquaTrend
status. Care should be taken when determining the location of the
Master AquaTrend Interface.
Every AquaTrend Interface is shipped in an undefined state. When connecting
only one AquaTrend Interface to the network, it must be designated as the
Master AquaTrend Interface.
Set the system AquaTrend Interface to Master status as follows:
1. Upon initial power-up, select MASTER and press the ENTER key.
2. Press Enter to select Network Manager to ON. After a brief delay, the
display will show the data display screen (CHANNEL NOT ASSIGNED).
3. Press the Menu key to proceed to the Main Menu.
3.1.1 Adding Remote AquaTrend Interfaces to the Network
Upon power up, new AquaTrend Interfaces on the network will search for a
Master AquaTrend Interface. (The exception is when installing an AquaTrend
Interface that has previously been installed as part of another AquaTrend
network. In this case, the AquaTrend that is new to this network will not
automatically check for a master. To force it to check, press the EXIT key
when instructed to install the remote from the network manager.)
Once a master is identified, the additional AquaTrend Interfaces will assume
remote AquaTrend Interface status and can be added to the network using the
instructions in
section 3.4.2 , Adding a Device to the Network .
The Master AquaTrend Interface should not be changed to a remote unless
you want to change the location where network operations are performed.
A change from Master to Remote AquaTrend Interface status will erase all
network information, requiring you to restore network connections.
