SSST900-500 Smart Spread Spectrum Transceiver

Features

Description

* Small Size: 1.295” by 1.410” by 0.255”

* Serial Control and Configuration of the Wireless Link.

* Supports a 254 node point-to-multipoint network

The SSST900-500 combines a spread spectrum

transceiver and micro-controller in a single, easy-to-

use, FCC Part 15 Registered module. The embedded

communications controller manages the Frequency

Hopping Spread Spectrum (FHSS) link and the host

system interface.

* Programmable Transmit Power Output 100 to 500 mW.

* Typical Receiver Sensitivity -100 dBm

* Obstructed signal range to 1000 feet;

* Wireless Data Rate 76.8K bps, half-duplex

The SSST900-500 supports two unique features to

simplify wireless networking. Count-Off™ allows the

network master to quickly retrieve the status of 125

remote nodes with a single broadcast command.

SensorOnAir^TMeliminates the need for an application

controller by utilizing the communications controller to

directly manage analog inputs and digital control lines.

* Low power Consumption

SSST900-500: 1000 mA@ 3.3Volts; when transmitting

at 500 mW output power; less than 1 mA of current

flows in Sleep Mode or Power-Down modes

* SensorOnAir^TM(patent pending)allows direct

connection of sensors to the Smart Transceiver

* Count-Off^TM(patent pending) allows the host node to

download the status of all nodes in under 10 seconds.

We also offers a low power spread spectrum model,

the SSST900-10, for applications that require less range.

The SSST900-10 has an obstructed range of 300 feet but

is smaller, costs less and uses significantly less power.

* Operating Temperature Range of -40 to +85 C

* FCC Part 15 Registered
