Configuring Readers
76 Level 2 API

M6e - Set to an array of ints (1 through 4) to configure GPIO lines as outputs.
/reader/iso18000-6b
/reader/iso18000-6b/BLF
Type: Iso18000-6b.LinkFrequency
Default value: M4/5 = From reader; M6e = ISO18000-6b.LinkFrequency.LINK160KHZ
Writable: yes
Products: M4, M5, M6e, M6
This sets the backscatter (return) link frequency used by the ISO18000-6b protocol. See
the M6e Hardware Guide and M4/5 MercuryOS Advanced User Guide for full
configuration options.
/reader/iso18000-6b/modulationDepth
Type: Iso18000-6b.ModulationDepth
Default value: MODULATION99PERCENT
Writable: yes
Products: M6e
In some cases using the smaller modulation depth of 11% will result in improved read
range and read reliability as it allows more power to be transmitted to the tag. However,
the smaller modulation depth can also result in a greater reduction in performance when
interference is present.
