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!
