3. System Requirements
The 505DSP transceiver is controlled by software residingonyour PC. The software Will
operatewith any computer runningWindows'"'
3. I, Windowst" 95 or WindowstmNT. Microsoft
requires
a 386DX or higher processorand 4 MB of memory (8 MB recommended) for Windows
95. Your computer must have at least 2 MB of free harddrive space, to store the 505DSP
control software, and a spare serial port. You Will also need a 4 - or 8 - Ohm external speaker
unlessyour computer is equippedwith
a sound card and speakers.
The
505DSP Transceiver operates from I2 Volts D.C. Your power supply must be capable of
deliveringat least 25 amps continuous duty. Use of small power supplies may result in distorted
audio, low power output, erratic operation
or all of the above.

If your carton is missingany of the above items when received, notivyour Dealer immediately.
5. Location
General - The 505DSP must be used indoors or in an enclosed vehicle. The transceiver and
control head are notweatherproof and
must not be exposed to the elements or to temperatures
exceeding
- I O to ' 50°C.
Transceiver - The transceiver may be mounted up to 23m (75 ft.) away from the computer.
Control cables approximately 2.5m (8 ft.) in length are supplied standardwiththetransceiver
while 7.6m and 23m
(25 and 75 e.) cable lengths may be purchased from Kachina.
For bench or desk top use,the 505DSP transceiver is designed to stand vertically or horizontally.
Self
- adhesive rubber feet are supplied and may be attached to either the side or bottom of the
cabinet. A spare Kachina logo is provided in case youwish to pivotthe logo from thefactory-
supplied position.
An accessory mountingbracket
is available from Kachina in the event you wish to securethe
transceiver
to a desk or wall or install in a vehicle. If installing the transceiver in a vehicle, care
should
be taken to ensure that the radio is protected from the elements and not exposed to
excessive shock or vibration. Rubber shock mounts are available from Kachina. Shock mounts
should be considered mandatory if you have a harsh ridingvehicle or expect to travel on rough
roads, and are recommended
for mobile installations in all cases.
Control Head - The 505DSP is supplied with a control head containingthe main power switch
and microphone, speaker, Morse key and phonejacks. Cables
are provided to install it in an

6. Control Head and Hardware Installation
Installing the Control Head Into Your Computer - Followthe steps below to installthe control
headand junction panel into your computer and
to connect the transceiverand control head.
I. Disconnectyour computer’s A.C. power cordfromthe power outlet before installingthe
control head.
2. Removethe cabinetfrom the
PC.
3. Select an empty drive bay and install the control head into the bay usingthe hardware
supplied. The threaded mounting holes onthe side
of the control head chassis Will usually
align with equivalentholes inthe PC chassis. However, since there is not a universal
standard
for the spacing of these holes,you mayfind there is noway to adequately secure
the control head
to the computer chassis. You may wish to consider situatingthe control
headona desk-top insuch cases.
4. Installthe 2 - portjunction panel into an empty stot onthe rear panel ofyour computer and
plugthe cable intothe connector onthe rear panel
of the control head.
5. Connect the 2.5m (8 ft.) control headcable from the front panel of the 505DSP
transceiver to the HDE I5 connector onthe junction panel. NOTE: Ifyou use your own
cable, it
MUST be 100% shielded and not longer than 23 meters (75 ft.).
6. Connectthe 76 cm (2.5 ft.) jumper cable from the DE9 socket onthe junction panel to
your computer’s serial port.

Using the Control Head Outside of Computer - Ifyou prefer not to installthe control head
into
your computer, if you don’t have any spare drive bays for example, an accessory kit (P/N
505ECH) is available that allows the control head to sit on a desk top. This kit includes a finished
(painted) cover for the control head, rubber mountingfeet and a cable that connectsthe RJ - I2
portonthe rear panel of the transceiver to your computer’s serial port. When this RJ - I2 cable
is used,the 2 - port junction panel and jumper cable described onthe previous page are not
used.
Note: The cables supplied with the 505DSP allow for m ounting the control head inside the computer
drive
bay only. Order the 505ECH lut for external (desk top) rnounting ofthe control head.
For external use of the control head, connect the 2.5m (8 ft.) control head cable (included with
the
505DSP) and the optional RJ I2cable (suppliedwith the 505ECH kit) according to the
diagram below:

The control head contains the main power switch and microphone,speaker, Morse key and
phonejacks.
The followingconnectors/jacksare located inthe control head:
MicrophoneConnector - The
505DSP's microphone uses an 8-
pin DIN connector. The
microphone input impedance
is
approximately 2000 ohms. The
microphoneamplifier will
accommodate low - or medium-
impedance dynamic microphones
providing
5 to 20 millivolts of
output. The microphonesupplied
with the
505DSP is prewired.
Wire your microphoneaccording
to Figure
5 if usinganother brand
of microphone.
Paddle, Morse Key InputJacks -
The PADDLE inputjack allows
Connection of a CW paddle (not
supplied) having
two switches, a
" dit " and a"dah." The common
wire is grounded. Wire the paddle
to one ofthe included 3.5 mm
stereo phone plugs, connectingthe

SpeakerJack - To connect to the control head, your external speaker must be wired to the tip
and outer portionsof
a 3.5 mmstereo phone jack. The speaker amplifier is designed to
accommodate 4 - or 8 - Ohm speakers. The 4 - Ohm speaker will give twice the audio output,
assuming both speakers are equally efficient. Ifyou want
to routethe audiothrough your
computer's sound card, you will need
to run a cable (not supplied) from the control head's
speaker jack to the audio input jack onyour sound card. You mustthen connectthe speaker to
your sound card's audio output jack.
