10 RC-100 Base Station
3.3 Synchronizing Multiple Base Stations and Channel Selection
If two or more server Base Stations need to operate at the same time in the same location,
they must each be set to an independent channel and synchronized accordingly.
The RC-100 wireless system uses frequency-hopping technology to maximize range and
minimize interference from other systems. When multiple server Base Stations are installed
within range of each other (approximately 2000 feet), Base Stations must be able to
synchronize with one another to ensure their hop sequences do not interfere with each other.
This is accomplished by the use of sync groups. A list of the sync groups and their
corresponding channel numbers and channel groups are shown in the table below.
Sync Group Channel Number Primary Channel Group Extended Channel Group
1 0 All
2 1 2, 3, 4, 5 7, 8, 9, 10, 12(C), 13(D), 14(E), 15(F)
3 6 7, 8, 9, 10 12(C), 13(D), 14(E), 15(F)
4 11(B) 12(C), 13(D), 14(E), 15(F)
The “Channel Number,” “Primary Channel Group”, and “Extended Channel Group” entries
correspond to the settings on the CHANNEL rotary switch (Figure 6) and handheld settings
that pertain to the “Sync Group” shown on the same line. Each “Primary Channel Group”
lists the channels that will attempt to synchronize to this sync channel as a first choice. If any
Base Stations set to these “Primary Channels” are within range of a Base Station set to the
corresponding sync channel number, the two Base Stations will sync. The “Extended
Channel Group” lists channels that attempt to synchronize to the corresponding sync
channel as a second or third choice. When these channels are not within range of their
primary sync channel, they will attempt to synchronize to the corresponding sync channel.
When a Base Station is synchronized to a Sync Group, the “IN RANGE” LED (Figure 10) will
flash briefly approximately every 5 seconds with the number of times flashed corresponding
to the sync group: 1 = Channel 0, 2= Channel 1, 3=Channel 6, 4= Channel 11 (B).
Any Base Stations set to channels in the “Channel Groups” section will continuously scan for
sync Base Stations whenever no handheld controllers are connected. This will allow these
boards to be powered up in any sequence and still obtain network synchronization.
