Frequency Units
All frequencies in the M6e are expressed in kHz using unsigned 32-bit integers. For instance, a carrier
frequency of 915 MHz is expressed as 915000 kHz.
The hop table for any region may consist of any permitted channels within the frequency limits for that
region. A permitted channel is one that is at the lowest permitted frequency or is a multiple of the minimum
channel step size, up to the highest permitted frequency. The following table gives the frequency limits and
minimum channel step size for all regions.
The user may define channels in a hop table to the nearest kHz (within the high and low frequency limits)
without receiving an error message, but if that request is not for a permitted channel, the actual frequency
used by the reader will be the first permitted channel below the requested frequency. For example, in the
NA region, setting a frequency of 902,999 kHz results in a setting of 902,750 kHz.
An error message will result if an attempt is made to set channels outside of the allowed frequency range
for a region. Changing regions will automatically re-install the default hop table for that region, erasing any
custom channels which may have been defined.
Frequency Hop Table
The frequency hop table determines the frequencies used by the M6e when transmitting. The hop table
characteristics are:
• Contains up to 62 frequencies.
• Valid frequencies for the region currently selected.
• Inability to change individual entries after uploading without reloading the entire table.
