ThingMagic M6e User Guide
29
The additional GPO line is configured just like the first two, using the /reader/antenna/ portSwitchGpos
parameter. Once GPO lines are configured to act as multiplexer controls, you may use the virtual port
numbers as if they were physical ports on the reader.
Port Power and Settling Time
The M6e allows the power and settling time for each logical antenna to be set using the reader
configuration parameters
/reader/radio/portReadPowerList and / reader/antenna/settlingTimeList,
respectively. The order the antennas settings are defined does not affect search order.
NOTE: Settling time is the time between the control lines switching to the next antenna setting and RF
turning on for operations on that port. This allows time for external multiplexers to fully switch
to the new port before a signal is sent, if necessary. Default value is 0.
