The RX line is a 3.3-volt logic CMOS input and is internally pulled up with a resistance value of between 20 and 60 kΩ (40 kΩ nominal). It must be low before the module is turned off and low before the module is turned on. This can be ensured if interface drivers are used that are powered by the module itself, as shown in the interface board example.
ThingMagic M3e User Guide 12 On power up, ThingMagic M3e module configures its GPIOs as inputs to avoid contention from user equipment that may be driving those lines. The input configuration is a 3.3-volt logic CMOS input and is internally pulled down with a resistance value of between 20 and 60 kΩ (40 kΩ nominal). Lines configured as inputs must be low whenever the module is turned off and low at the time the module is turned on. GPIOs may be reconfigured individually after power up to become outputs.

ThingMagic M3e User Guide 31 Power Management ThingMagic M3e is designed for power efficiency and offers several power management modes. When transmitting, the power consumption can be minimized by using the lowest RF power level that meets the application requirements and powering the module with highest DC input Voltage. A “Power Mode” setting determines the power consumed during periods that the module is not actively transmitting. Power Modes - is set in /reader/powerMode. www.JADAKtech.
ThingMagic M3e User Guide 43 Power Modes The Power Mode setting (set in /reader/powerMode) allows the user to trade off increased RF operation startup time for additional power savings. The details of the amount of power consumed in each mode is shown in the table under Idle DC Power Consumption. The behavior of each mode and impact on RF command latency is as follows: • PowerMode.NORMAL - Tag Read • PowerMode.IDLE - • PowerMode.
