delayed with a user-defined time in msec., which allows the maximum flexibility towards any Radio/Amplifier configuration. The user
can set different delays time for RadioA / AmplifierA and RadioB / AmplifierB, through software configuration and these settings are
retained in the EZMaster memory. This feature is available for all of the EZMaster’s PTT input control ways: Parallel Port, Serial Port,
USB Port, Foot Switch, and Winkey.
Radio Interface
Two Radio interfaces are available to control several types of radio manufacturers’ and models: ICOM, YAESU and KENWOOD
transceivers have been tested and work properly. Each, separate, interface works independently, so different types of radios can be
used simultaneously. Moreover, the radio control data, in the STANDARD and EXTENDED mode, can be addressed to the corresponding
USB or COM port, while in the ADVANCED MODE they can be routed to a single USB or COM port, allowing the management of 2 radios
from one single port.
Antenna Relays Output
The two DB25 male connector in the back of the panel are the Antenna Relay output that include 16 different sink lines for each one,
10 are unique for each output and the remaining 12 are shared between them. The maximum sink current, from each one of the 32
output lines, is up to 150ma. Each line can be configured for Radio Status, RX and TX, and both radio simultaneously allowing a wide
range of flexibility to define any configuration. A user defined delay time could be added to each Output to avoid “hot switching” with
slow Antenna Coax Relays.
An optional 32 Relays card can be added, allowing a sink or source current up to 1A each line, useful when the antenna switch boxes
are on the towers connected with long cables.
Parallel Band Decoder
EZMaster Parallel Band Decoder works in STANDARD and EXTENDED MODE, data from Parallel port are decoded according to the
Standard Parallel Band Data Configuration table on page 47. User can define whether to decode or not data from the Parallel port,
allowing the user to connect an existing external decoder if preferred. EXTENDED MODE allows the user to define for each of the 16
decoded combination a RX/TX Matrix Profile, where more that one Antenna Matrix line can be selected, allowing complex antenna
switch for both RX and TX status, using Parallel port data.
Microphone
EZMaster microphone facilities allows connection of two types of microphones connectors:
• a standard 8 pin microphone lead (an internal, user configurable, dipswitch allows to match the microphone’s manufacturer pin
out)
• a 3.5mm jack mono connector, suitable for connecting a headset microphone.
See below, in “The front panel” description section, for the DIP switch configuration Table.
Power Supply
EZMaster allows two different power supply sources:
− a self-powered via the USB plug, which allows EZMaster to operate without the usage of external DC power supply
− via an external, 9-15V DC, power connector
The external source is needed when the optional Relay card is installed, or when the current for the Antenna Relays Coax switches is
supplied by EZMaster itself.
Smart Command Interface
EZMaster is a micro-controlled device. This feature allows for external control through simple commands that perform all the functions.
The Advanced Mode then overcome all the possible limitations in the way software programs communicate with external devices: the
USB/Serial connection and the SCI (Smart Command Interface) allow the software developer to use all the comprehensive features of
EZMaster without any hassle and port configuration problems, when more than two devices need to be connected to the PC.
The unique command mode interface (CMI) allows control of each of the EZMaster outputs with a simple command, while the built-in
CW keyer and the macro commands allow anyone to develop software code in a easy way thus reducing the time to support a new
device at the only cost of few hours of work.
The Command Mode Interface has a simple syntax, and each command is immediately executed, excluding the WinKey commands that
are only routed to the WinKey and managed directly with the WinKey rules. The commands can have parameters and can wait for
answer, even if most of the commands are without any answer and are immediately executed.
Firmware Upgrade Facility
EZMaster has a built-in software download facility that allows the user to update the firmware in few minutes, thus maintaining an up-
to-date device with the last available release.
This is a valuable and powerful feature when any new functionality is added to the device itself.
The updated firmware releases can be found in the Download Product Firmware section of the web site at
