DRM Compliant Mode
This mode maximizes performance in dense reader environments, minimizing interference when used
with other M6e or similar DRM-compliant readers, and is fully compliant with the Gen2 DRM spectral
mask.
Power Save Mode (non-DRM Compliant)
This mode reduces the power consumption during RF operations but is not 100% compliant with the
DRM spectral mask. This can result increased interference with other readers and reduce overall
systems performance.
Event Response Times
The following table provides some metrics on how long common M6e operations take. An event response
time is defined as the maximum time from the end of a command (end of the last bit in the serial stream) or
event (e.g. power up) to the response event the command or event causes.
Save and Restore Configuration
The M6e supports saving module and protocol configuration parameters to the module flash to provide
configuration persistence across boots. This was introduced to support Autonomous Operation, but can
also be used to reduce the amount of communication necessary to bring a module up to operating state
following a reboot. The parameters that can be saved include:
• Region
• Baud Rate (for serial interface)
• Default Protocol
• RF power
• Antenna search list
• Gen2 “M” value
• Gen2 BLF (Tari will be 25 usec if BLF=250 and 6.25 usec if BLF=640)

Notes
Power Up Application Active (with
CRC check)
1500 This longer power up period should
only occur for the first boot with new
firmware.
Power Up Application Active 120 Once the firmware CRC has been
verified subsequent power ups do
not require the CRC check be
performed, saving time.
Tag Read RF On 20 When in Power Mode = FULL
Tag Read RF On 50 When in Power Mode = MINSAVE
Tag Read RF On 120 When in Power Mode = SLEEP
Change to MINSAVE PowerMode.MINSAVE 5 From Power Mode = FULL
Change to SLEEP PowerMode.SLEEP 5 From Power Mode = FULL
