SOFTWARE-DEFINED ARCHITECTURE Envoy™ uses latest-generation high-performance Digital Signal Processor (DSP), Field-Programmable Gate Array (FPGA) and microprocessor technology. This provides market-leading performance and the assurance of protection of your investment, through future-upgradability to support evolving standards.
INTUITIVE OPERATION With its large, high-resolution, back-lit colour display and customisable icon-based menu system, Envoy™ is as simple to operate as modern smartphones. Making calls is as simple as navigating to your contact list, locating the desired contact and pressing the "call" button.
To ease the training burden for non-English background users, the Envoy™ user interface and PC programming software are available in languages other than English.
EASY TO DEPLOY Codan's TPS-3250 Programming Software provides a powerful user-friendly tool for the rapid configuration of your Envoy™ Transceiver, and enables installation of profiles via direct USB connection or USB memory device. Ease of field deployment is assured through the USB Smartloader capability. Alternatively Envoy™ can be configured directly through the intuitive menu system, with the assistance of the in-built quick-start guides. Access to settings can be selectively protected via an administrator pin.
Envoy™ features Built-in Test Equipment (BITE). An automatic self-test is run on start-up, and additional tests can be run manually. A simple status LED indicates normal operation (green) or fault conditions (red). Remote management is also supported via over-the-air diagnostic and status calls.
Envoy™ continually monitors forward and reflected power. Voltage Standing Wave Ratio (VSWR) can be displayed to the user, and poor VSWR (e.g. caused by an untuned antenna) is quickly reported.
SMART MONITORING AND SCANNING When an operator is absent, Envoy™ generates an automatic log containing the caller's identity, time and channel number that can be displayed upon their return. With multiple net adaptive scanning, Envoy™ automatically adjusts scan times for multiple networks according to the channels preset scan times. This feature gives the most efficient scanning time possible for Selcall, ALE and voice detection.
Envoy™ features flexible scanning networks, with up to 20 scan tables containing up to 100 channels. Scan rates of up to 8 channels per second are possible, which provides increased capacity for HF networks based on Envoy™.
With the syllabic Voice Mute, Envoy™ effectively detects voice patterns even in high-noise environments. This ensures mute is only opened after it detects speech on any scanned or monitored channels.
When Selcall or ALE selective calling is implemented, users are able to scan multiple channels or networks. The operator is only alerted when a call addressed to them specifically is received. This relieves the operator from continuous manual monitoring for relevant incoming traffic.
HIGH PERFORMANCE. INTEROPERABLE CALLING CAPABILITY
Envoy™ supports currently used calling standards including CCIR based Selcall, FED-STD-1045 Automatic Link Establishment (ALE) and MIL-STD-188-141B ALE. This ensures full interoperability with earlier generation Codan, competitor and legacy transceivers.
Envoy's™ CALM™ (Codan Automated Link Management) takes conventional ALE to the next level through dynamic channel characterisation, maximising the probability of clear communications. In addition, Envoy™ delivers advanced capabilities, such as call voting and data optimised calling.
INDUSTRY-LEADING RF PERFORMANCE
Clear voice communications and reliable data communications are the prime objectives of Envoy™. This is achieved by industry-leading RF performance specifications, together with Codan's renowned Easitalk™ noise-reduction technology.
INTERNAL EMAIL CAPABLE DATA MODEM
Envoy™ is available with a robust internal data modem, providing chat and email capability. Unlike competitor offerings, this does not require the installation of an additional hardware module.
VOICE SECURITY Envoy™ has a choice of three internally fitted voice encryption options to suit all levels of communications security.
The CIVS voice encryption option is a cost effective software enabled voice scrambler capability that is simple to use and provides a basic level of voice security.
The CES voice encryption option provides high level 128 bit voice security. Up to 97 16-digit user programmable keys are provided. An additional layer of security is provided through the ability to assign a PIN number during a secure communications session.
Voice encryption option for Envoy™ are fully integrated with core Transceiver functions like Selcall and ALE scanning to ensure simplicity of operation.
IP REMOTE CONTROL, CONNECTIVITY Envoy™ features USB and Ethernet connectivity. End-user benefits include the capability for remote control over IP, and the convenience of deployment of configuration profiles through USB memory sticks. Programming and firmware upgrade are supported at high speed.
GPS SUPPORT Envoy™ supports connection of GPS via NMEA0183 compatible GPS receivers. This enables polling and sending of GPS positions over air. Distance and bearing to other users can be displayed. When used with Internav™ CHF tracking PC software, up to 100 vehicles can be tracked. Internav™ provides advanced features such as corridor and alarm zones, waypoints, and recording of emergency events.
