Flexible Connectivity

Transparent and robust versatility combine with absolute ease of use to create the SATELLINE-EASy high performance UHF radio modems for critical wireless connections and high accuracy GPS.

Maximizing transparency and reliability with a number of advanced data transfer functions and extending range with a precision tuned receiver, the EASy modems deliver about twice the range of 900 MHz radio of all types, and are suitable for indoor, outdoor and mobile applications as a repeater, base, or remote.

Wide Tuning Range and Selectable Bandwidth

Capable of communicating even in environments with sporadic 12 dB weaker interference on the exact same frequency, SATELLINE UHF radio modems have adjustable signal threshold to focus only on selected stronger signals enhancing operation in densely populated areas and regions with excessive ambient radio frequency noise.

Analog RSSI Output

SATELLINE 3AS & EPIC modems feature an analog output of received signal strength which can be connected to local control system hardware to enable monitoring of the link quality and ambient noise levels within any desired application. This free feature must be stated at time of order.

Forward Error Correction

Encapsulating device data packets network wide with self-correcting algorithmic data, FEC, gives SATELLINE radio modems the internal tools to actually eliminate erroneous bits and reconstruct the original data packet when there are slight errors from long distances or heavy interference.

Error Check

When data quality is essential, SATELLINE radio modems come with SATEL’s proprietary Error Check and full CRC16 error checking which can be set to either completely reject any data packet with errors transparently, or pass the packet and checksum intact to a device master.

Strong Encryption

Optional AES-128 encryption support adds strong protection to your data over the air, with minimal overhead.

Display & Operator Interface

Crowning SATELLINE advanced technology is the built-in backlit LCD display that provides users with vital diagnostic information about received signal strength, frequency, power supply and data settings at a glance. Durable pushbuttons give instant access to virtually all of the radio settings through easy to read menu selections. SATELLINE “D” display models allow for setting up, using, configuration changes, and testing to all be done without ever using a laptop, PC or any other device.

Simple & Accessible Programming

Mechanically switched into programming mode by grounding the “Programming-Pin”, all of the radio settings are accessible using any terminal software. Self-guiding menus clearly display settings and selectable options in plain English. SATEL’s SaTerm software simplifies advanced configuration by providing an additional graphic interface for some of the more complex aspects like message routing, creating settings profiles, and updating firmware.

Transparent Wireless Communication

Eliminating complicated external synchronizing signals by using asynchronous data streams, the entire data stream is transmitted less than 1 millisecond after it is received arriving at the other end intact and without interruption or re-packetizing and allowing for the highest level of transparency to connected devices.

Test Mode

Cutting down on installation and repair times, SATELLINE radio modems feature low and high duty cycle testing to simplify antenna testing and alignment, link, system and path tests. When combined with the benefits of conveniently displayed signal strength on the receiving modem, antenna installation times are reduced to a minimum.

Repeater Functionality

All SATEL radio modems are capable of store-and-forward repeater functions or may be paired together for duplex repeater operation. Repeater functionality allows for virtually endless connection range and network coverage. Message routing and addressing functions can be added to create robust and far-reaching network topologies.

Advanced Addressing Functions

Configurable with dual transmission and receive addressing and network identification, SATELLINE radio modems can remain transparent and universally compatible with devices while still extending networks across longer distances through one or more repeaters or to isolate multiple sub-networks without receiving duplicated or conflicting device data.

Automatic Message Routing

By identifying source and destination addresses for data in many pre-configured or user defined polling data protocols, SATELLINE radio modems automatically direct data packets to their destination by finding the route within the radio network itself transparently to connected devices. Routes are automatically created if a remote location is moved, a repeater station is lost, or in systems with mobile remote devices. The AMR function is configured using SATEL’s free SaTerm PC software. With SaTerm, allows users are able to graphically design a radio modem network, troubleshoot, and make radio modem firmware updates by simply drawing connections between radio modems, while routing information is automatically generated.


Advanced control and diagnostics are available from all SATEL radio modems using SATEL Language (SL) Commands. Experienced users and manufacturers with integrated SATEL solutions can utilize “SL-Command” blocks to interact directly with all SATELLINE radio modems.

Flexible Data Interface

Capable of operating on as little as 3-wire (Tx, Rx, & ground) communication or as much as 25-pin rs-232 with full hardware handshaking. SATELLINE radio modems directly accept most common wiring formats.
