Procedure 2: Finding collocation values using Frame Calculators

Using the Tools => Frame Calculator on an OFDM module, enter the desired Downlink
Data %, Range, and Control Slot settings, click Calculate, and observe the "Rec SEQ
Start" value.
Using the Tools => Frame Calculator on an FSK module, enter the desired Downlink
Data %, Range, and Control Slot settings, click Calculate, and observe the "Rec SEQ
Start" value.
Iterate, usually adjusting the FSK Downlink Data % and the OFDM Downlink Data %
values by a few percent each time, until the "Rec SEQ Start" times of all collocated
modules are within 300 bit times of each other.
Configure the OFDM modules using the resulting OFDM values, and the FSK modules
using the resulting FSK values.
The frame calculator page (FSK and OFDM) has been simplified with Release 10.3 to show only
information pertinent to co-location. It will now display AP TX end time and AP RX start time which
allows the operator to more easily calculate co-location duty cycles.
