PROGRAMMING (OPTIONAL)
A programming cable is needed to program different channels or functions on
the ZA-725. The programming cable links the radio to USB port on a PC or
laptop.
USB installation:
USB cable driver software for your computer operating system is available
for free downloading from www.zartek.co.za or from the cable manufacturer
website Prolific (driver for PL2303 USB-Serial cable). Install the correct
software and plug-in the cable to the PC. The computer should locate the
cable and configure it automatically. You can check that the cable is working
by locating it in DEVICE MANGER > PORTS > PROLIFIC USB – SERIAL
COMM PORT.
Software installation:
Programming software for the ZA-725 is available for free download from
www.zartek.co.za . Install the software on to a PC by following the installation
steps. Once installation is finished, an icon called “ZA-725 User PC
Software” will appear on the screen.
Connect the USB cable to the PC and plug-in the twin connector into the
speaker/microphone jack on the side of the ZA-725 radio. Ensure that there
is a charged battery connected to the radio and switch the radio on. Start the
program and a window will appear. The software automatically finds the
correct port of the programming cable.
Reading data:
Click on the “READ” left icon (arrow away from radio) and press “OK” to
begin reading the data from the radio. The RED LED on the radio will flash
as data is being read. Once loaded, the data can be edited to the appropriate
channels and settings and then saved or printed for future reference. See
below for instructions on each function.
Writing data:
After data is entered, click the “WRITE” right icon (arrow towards radio) to
program the radio. Press “OK” to begin writing the data to the radio. The
GREEN LED on the radio will flash as data is being written. Once finished,
switch the radio off and unplug the cable from the radio. Additional radios can
be programmed by plugging in the cable to the radio, switching it on and
following the “WRITE” procedure.
Licence-free bands:
The RX Freq. (MHz) column refers to the frequencies that can be selected on
the radio. The 8 frequencies in the 446MHz band are represented by the 8
channel numbers, 1-8, in the table. These channels correspond to the
channels on other 446MHz license free radios, such as the Zartek Pro8. The
5 frequencies in the 464MHz band are represented by the 5 channel
numbers, 1a-5a, in the second table. These channels correspond to the
channels on other 464MHz license free radios, such as the Zartek Pro5 or
ZA200 (model# 21-1860-AF).
