Configuring Readers

(NOTE: the settlingTime is associated with the TX port, the paired RX port is not

relevant), and the second element is the settling time in microseconds. Ports not listed

are assigned a settling time of zero.

/reader/antenna/txRxMap

Type: array of array of 3 integers

Default value: all the antennas in /reader/antenna/portList in monostatic mode. i.e. for

the M5e = [[1,1,1],[2,2,2]]

Writable: yes

Products: M5e (and derived products), M6e

A configurable list that associates transmit ports with receive ports (and thus selects

monostatic mode or bistatic mode for each configuration) and assigns a

Antenna Usage

number to each. Each list element is a length three array, [ [ A, B, C], ...], where:

A is the virtual antenna number

B is the transmit (TX) physical port number

C is the receive (RX) physical port number.

The reader will restrict which combinations are valid.

Example: Using an M5e configured for both monostatic and bistatic operation, with the

bistatic configuration (TX=1, RX=2) assigned virtual port 1 and the monostatic

configuration (TX=1, RX=1) assigned virtual port 2:

r.paramSet("/reader/antenna/txRxMap", new int[][]{new int[]{1,1,2},

new int[]{2,1,1}});

/reader/gen2

See the Performance Tuning sections: How UHF RFID Works (Gen2) and Optimizing Gen2

settings for details on how the following settings related to reader performance and how to

select the best settings for your usecase.
