Transceiver V-in power (see note)	5 to 16V 2.5W average, 3.5W peak @5V DC 2.1W average, 3.3W peak @12V DC
Transponder V-in power (see note)	4.5V to 28V 1.7W average 2.9W peak @5V DC 1.3W average, 4.1W peak @16V DC
Serial Comms Voltage Levels	3.3V TTL or 5V TTL, auto sense

Note: Power supplies for both units must be able to supply burst currents to prevent drop-out and erratic operation. While the transmitter will work with a low impedance 5V supply we recommend using 9V or higher, unless you know how to figure out if your 5V power supply is low-enough impedance.

Note: Resolution ≠ Accuracy!
