RC-100 Base Station 9
After exposing Base Station circuit board, use a small flathead screwdriver to turn the “S1”
rotary switch labeled “CHANNEL” to the desired channel.
Note: The wireless handheld and Base Station must be set to the same channel in order to
communicate. To select the channel in the wireless handheld controller, refer to Section 4.1.
Two server Base Stations cannot be powered up in the same area with the same channel
setting, or they will interfere with each other. To avoid this, on power-up the server Base
Station checks to see if there are any other servers located nearby. If another server is
detected, the “IN RANGE” LED (Figure 8) will flash quickly to indicate interference, and
continue to flash until the channel is changed or the conflicting Base Station is turned off.
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.
