Appendix B: RF Channel Number vs Operating Frequency
Operating frequency must be assigned in compliance with the rules set out in each RF band section below.
Frequency is factory set, so at time of order, the factory must be advised which RF channel should be selected
based on knowledge of existing RF systems that are already operating on site.
Band B (433-434MHz)
This band starts at 433.0775MHz. Channel spacing is 25KHz.
There are 69 channels available and channel frequency is coded with a letter and two digits.
Channel A00 will be 433.0775MHz. Channel A68 will be 434.7775MHz.
Band B Channel Spacing Rules
If the MSD is to be installed less than 100m (330’) from another RF system (Cattron or other), select a frequency
at least 50KHz (2 channels) away from other frequencies in use.
Band D (450-470MHz)
This band starts at 450.000MHz. Channel spacing is 12.5KHz.
There are 1600 channels available and channel frequency is coded with a letter and two digits.
Channel A00 will be 450.000MHz. Channel B00 will be 451.250MHz. Channel Q00 will be 470.000MHz.
Band D Channel Spacing Rules
If the MSD is to be
installed less than 100m (330’) from another RF system (Cattron or other), select a frequency
at least 50KHz (4 channels) away from other frequencies in use.
Band F (902-927MHz)
This band starts at 902.6MHz. Channel spacing is 100KHz.
There are 349 channels available and channel frequency is coded with a letter and two digits.
Channel A00 will be 902.6MHz. Channel B00 will be 912.600MHz. Channel C49 will be 927.500MHz
Band F Channel Spacing Rules
If the MSD is to be installed less than 100m (330’) from another RF system (Cattron or other), select a frequency
at least 200KHz (2 channels) away from other frequencies in use.
