1. Purpose and Scope of Document
This document was incepted in order to provide to the user clear guidelines regarding
the usage of the Nivis RF-P9-06-01-01 modem.
The scope of this document is limited to the first revision of the Nivis Amplified Radio
Modem, part number RF-P9-06-01-01.
2. Overview of the Radio Modem Hardware
The Nivis Radio modem RF-P9-06-01-01 is a frequency-hopping wireless module that
allows wireless communication using a standard asynchronous serial data stream. The
half-duplex transmission of the modem can sustain a continuous data stream at the
specified data rate of 9600 bps.
The pin-out of the Nivis radio modem is presented in the figure below.

The radio modem consists of three functional entities:
1. Digital section – processor, EEPROMs, Power-on-reset circuitry
2. RF section – Chipcon RF transceiver and LNA
3. Power amplification section – MAX2235 power amplifier
Power is supplied to the modem through pins 1 and 2.
Pin 1 must be supplied with 3.6 Volts and powers the digital and RF functional entities
of the modem. The modem has two internal 3.3 V LDOs which are powered through this
pin. The LDOs require a dropout voltage of 200 mV.

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 11 and 12 are the TX and RX pins of UART 1. 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.
A table of the radio modem pins is provided below, describing the purpose and
functionality of the pins and the max voltage range on the pins.

3. Operation of the Nivis Radio Modem
The NivisLink application was developed in order to exercise the features of the Nivis
Radio modem. The NivisLink application is software application composed of a firmware
hex file which is to be loaded onto the modem and a GUI that controls various features
of the modem.
3.1. Getting started
Install the NivisLink GUI on a PC and connect the serial port of the PC to the Nivis radio
modem evaluation board RFB-01-01.
Load the radio modem with the NivisLink hex file provided.

The figure below depicts the “Serial” tab of the NivisLink GUI.
3.2 Read Calibration EEPROm
Note: The following procedure assumes that the modem used has already undergone the
calibration procedure. For tune-up and calibration procedure consult the “Tune-up Procedure”
document.
The SN, DNA, PA Max level, temperature sensor calibrtation value and other calibration
data necessary for the operation of the Nivis radio modem is stored in the calibration
EEPROM.
By pressing the “READ I2S” button the content of the calibration EEPROM is displayed
in the tabs provided for various parameters.

version 1.0
The following parameters will be displayed
•Serial Number – unique identifying ID of the modem
•DNA – network identification number
•Power Amplifier max level – maximum value of the power amplifier gain
•Firmware version
3.3 Transmission
In order to set the modem in transmit mode the “SET TX MODE” button must be
employed. The transmit tab will allow the user to select the TX frequency channel on
which the transmission should take place. 50 frequency channels can be employed
starting with the 910.5 MHz channel and than incrementing by 330 kHz up to 927.5
MHz.
The user can also select the output power of the modem by employing the TX Power
knob.
The MOD and UNMOD knob permits the user to select if the transmitted signal is
modulated or un-modulated (carrier).
3.4 Reception
In order to set the modem in reception the “SET RX MODE” button must be pressed.
The mode will enter reception on the frequency channel selected in the adjacent tab.
3.5 Modify Register Values
The NivisLink application also gives the user the flexibility to directly control the
functional registers of the CC1020 transceiver. This gives the user complete control
over every aspect of the RF functionality of the modem.
These register should only be overwritten by users that are knowledgeable of the
CC1020 transceiver.
For a list and explanation of each CC1020 register consult the datasheet of the CC1020
transceiver.
3.6 Additional Features
The NivisLink application also permits the user to view various other parameters of the
radio modem.
