2.5.1.2
Alternate Shortcut Entry Method to This Display
Because this display is useful when locating a clock for improved signal strength, you
can quickly enter and exit this mode by pressing only the Set switch while in the Normal
Operational mode. Pressing Set a second time returns immediately to the Normal
Operational mode without sequencing through the whole menu.
2.5.1.3
Setting the Group and Sub-Group Addresses
The TimeView is a multi-system clock and is individually addressable. This function is
used to send commands to individual or groups of clocks and not others. Multi-purpose
clocks may have Status and/or Alert Indicators or a buzzer that can be controlled from a
central TimeBurst Multi-System Controller. Mode steps 2 through 7 are used to set
these addresses.
2.5.1.4
Group and Sub-Group Addressing
All clocks have two addresses: the Main Group address and the Sub-Group address.
The default setting for both the Main Group and the Sub-Group is 000 so if this feature
is not to be used, it can remain zero and you can skip to the next section. All clocks
receive the time broadcasts, so if your clock only displays time, you do not need to be
concerned about addressing.
The Main Group address range is 001 – 127. A Main Group address of 000 sets the
clock to listen to all commands. The Sub-Group address range is 001 – 255. A Sub-
Group address of 000 sets the clock to listen to all commands for the Main Group.
The Main and Sub-Group addresses can be used to control multiple clocks. For
example, consider a large company with multiple buildings. An assignment can be
made as follows:
Clocks located in:
Main Group Address
Building A
001
Building
B
002
Building
C
003
Clocks located:
Sub-Group Address
Near an Exit
001
On the Second Floor
002
On the Factory Floor
003
Configured this way, commands can be selectively sent as follows:
