Minimum switching time, ie minimum amount of Idle time before a
radio will switch between Rx and Tx state or Rx and Rx state
2.3.1. Tx Rx Enable 4 State (OFDM only)
External Tx and Rx control lines with 1.8V logic.
2.3.2. External GPIO 1 & 3
Not Used
2.3.3. Red and Green LED
The external Red and Green LEDs will give the user some basic status of the radios current state.
 Green only LED on -> The NANO is in sync with another radio
 Red only LED on -> The Nano’s RF is turned off via the software Tx/Rx enable/disable
setting.
 Green and Red LED on (Yellow) -> The NANO RF is on, but NOT in sync with another
radio.
2.3.4. Tamper
Not Used
2.3.5. RF Output Power
The NANO output power will remain unchanged regardless of the RF environment. The NANO
output power is based on frequency and is calibrated per Radio Card. Each radio will have its
own calibration programmed and available for the user to view. Each NANO may vary from 1-2
dB of output power. See section 7.1 NANO output power for more information on determining
the output power measured on a particular frequency.
