Connecting your EZMaster to Your Computer
Connect Your EZMaster to a Power Source
As illustrated before, there are two ways to supply power to your EZMaster:
• You may use an external power supply by connecting the EZMaster to a 9-15V (13.8V nominal) DC source available on your bench.
• You may use the USB port as a power source.
The Power indicator (LED), on the front panel, will turn ON if a power source is connected. If the USB port is connected, then also the
USB LED will turn ON. If the power indicator (LED) does not turn ON as expected, the unit may be defective, so you should check with
your dealer.
Your USB Cable
The USB Cable needed to connect your EZMaster to your computer is supplied within the EZMaster package.
Your Serial Communication Cable
If the logging software/computer you plan to use requires a separate serial connection, you will need a serial cable to connect your
EZMaster (RS-232 connector – DB-9 female) to your computer. This is a standard off-the-shelf, RS232 modem cable which is not
supplied with the EZMaster. You will need to purchase one, or construct one.
The COM connector (DB-9 Male) on the back panel of the unit is multi-functional and provides an interface for the CW-key and PTT
signals from a logging program as well as the PC connection for a the interface that can be used to control any radio from the logging
program. To insure a complete compatibility with all application, EZMaster has two separate ports for data transfer (radio interface) and
CW-key / PTT signals.
Your LPT Parallel Cable
The Parallel Cable needed to connect your EZMaster to your computer is not supplied with the EZMaster. A straight, pin-to-pin, DB 25
male / female cable should be available from your computer dealer. The LPT connector (DB-25 Male) on the back panel provides the
unit with access to PC control of the first four Voice and CW messages, CW keying, PTT and Radio A/B switching from the computer.
For the LPT port pin out please refer to the Parallel Port in the Connector’s pinout section of this manual.
