DUAL ANTENNA INPUTS
Dual antenna option allows for two antennas to be simultaneously connected to the Envoy™ that teamed with the smarts of Envoy, results in optimal coverage as the Envoy™ will use the antenna that provides the best voice quality.
INTUITIVE OPERATION
With its large, high-resolution, backlit 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.
Four control points (CP) can now be assigned for the one Envoy™ RF Unit. Each control point can be registered with the RF Unit and assigned a unique self ID-address. For each Control Point assigning self addresses and registering multiple control points.
If required the Control Point operator now has the ability to restart the RF Unit from the General / Restart RFU menu. This feature is especially useful in remote control systems where a restart of the RF Unit is required due to some profile changes made. Default Power Down Function is now available for both desk console and handset control points.
Default Power Down Function now is available. The Default Power Down Function allows You to select between “Power Down Control Point and RFU” or Power Down the “Control Point only”. This setting can be found in the Settings/Control Point menu of the control point and TPS. This function is useful when controlling an Envoy™ over Ethernet or you have multiple control points.
MULTI-LINGUAL
Envoy™user interface and PC programming software are available in languages other than English making training of new operators much simpler.
EASY TO DEPLOY
Envoy™ can be configured and programmed in the field via IP Remote Control or with a direct USB connection or USB memory device using 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.
BITE
Envoy™features Built-in Test Equipment (BITE) with automatic self-test is run on start-up. Additional tests can be run manually and a simple status LED indicates normal operation status – red or green. 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 pre-set 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 low rate modem option, or a high-speed MIL-SPEC modem offering up to 9600 bit/s data capability.
ISB Support for 2G HF Data Modem. ISB mode should only be used if the Envoy™ has an internal 2G data modem. Data Modem in conjunction with RC50-C software allowed to provide higher data rate up to 19200 bit/s on HF channel.
These are backed up by application software solutions supporting Email and Chat. All solutions compress data for minimal transmission time, and the high-speed modem utilises DRC (data rate control) to optimize the data rate to the present channel conditions.
VOICE SECURITY
Optimal voice clarity is provided through the use of a Mixed-Excitation Linear Predictive enhanced (MELPe) Vocoder. The MELPe Vocoder supports 600 bits/s, 1200 bit/s and 2400 bit/s user selectable data rates.
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-level128-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.
The AES voice encryption option provides 256-bit security according to the Advanced Encryption Standard, with up to 256 user programmable encryption keys.
All voice encryption options for Envoy™are fully integrated with core Transceiver functions like Selcall and ALE scanning to ensure simplicity of operation.
