1. Purpose of Document
This document was created in order to provide to the user clear guidelines regarding the
usage of the Nivis RF-P9-06-01-01 modem.
2. Overview of the Radio Modem Hardware
The 2.4GHz Nivis Radio modem is an 802.15.4 wireless module that allows wireless
communication using a standard asynchronous serial data stream. The pin-out of the
Nivis radio modem is presented in the figure below.

The radio modem consists of three functional entities:
1. Transceiver section – processor, RF transceiver
2. RF section – BALUNs,RF PA, RF filter, RF switch
3. Non-volatile storage – Eeprom
Power is supplied to the modem through pins 1 and 2.
Pin 1 must be supplied with 3.3 Volts and powers the digital and RF functional entities
of the modem. The modem has internal filtering circuitry to smooth out the supply
voltage but it has no onboard regulators.
All of the remaining pins of the modem are I/O lines of the processor.
The voltage on any of the I/O lines should never exceed 3.3 V.
Pins 13 and 14 are the TX and RX pins of UART 1, pins 11 and 12 are the TX and RX
of UART2. If connecting to the serial port of a PC, a level-shifting transceiver must be
employed in order to provide the appropriate voltage levels on the RX and TX lines.
