3-Series Control System™ Crestron MC3
There are 16 possible channels ranging from 11 to 26. For optimum performance
when installing a MC3 in a Wi-Fi environment, do not set the MC3 to a channel
within a Wi-Fi channel band. Crestron recommends channel 15 or channel 20.
• Channels 11-14 are within Wi-Fi channel 1.
• Channel 15 is adjacent to Wi-Fi channels 1 and 6.
• Channels 16-19 are within Wi-Fi channel 6.
• Channel 20 is adjacent to Wi-Fi channels 6 and 11.
• Channels 21-24 are within Wi-Fi channel 11.
• Channel 25 is adjacent to Wi-Fi channel 11.
• Channels 26 is neither within or adjacent to any Wi-Fi band.
For detailed information on RF channels, refer to “Appendix A: The RF Spectrum”
on page 38 and “Appendix B: Optimum RF Reception Guidelines” on page 40.
Establish communication with the MC3 (refer to “Establishing Communication”
which starts on page 19), use Crestron Toolbox to set the operating channel. Set the
RF channel by selecting Functions | MC3… in Crestron Toolbox. Refer to the
Crestron Toolbox Help file for more details.
NOTE: Use Crestron Toolbox to set the RF channel before starting the acquire
process. The default RF channel is 15. If you change the RF channel on a device, it
will need to be acquired again.
NOTE: The Acquire mode can be activated approximately 15 seconds after
applying power to the MC3.
NOTE: In an environment with multiple gateways, only one gateway should be in
Acquire mode at a time.
NOTE: The MC3 must be placed in Acquire mode before an infiNET EX device is
placed in Acquire mode.
To acquire an infiNET EX device via the ACQUIRE button on the MC3:
1. Press ACQUIRE on the MC3 to enter Acquire mode. The accompanying
LED will illuminate, indicating the unit is ready to link to infiNET EX
devices.
NOTE: Acquire mode will automatically deactivate after one hour. This
default timeout period can be changed from Crestron Toolbox.
2. Bring the infiNET EX device within range of the MC3 and place it in
Acquire mode as described in its manual. The device will be automatically
acquired by the gateway within two minutes after it enters Acquire mode.
3. Repeat step 2 for each infiNET EX device to be acquired.
4. Press ACQUIRE on the MC3 to exit the Acquire mode. The LED will turn
off.
