Chapter 2
Power Supply and
Computer Installation
Overview
In this chapter, you’ll power up the DSP and connect it to the RS-232 serial port of your computer. After the
connection has been made, you’ll perform a quick check of the DSP’s internal firmware. You’ll also check the
DSP’s internal modem by performing the all-important “loop-back” test. When you’ve completed this chapter,
you’ll be ready to connect the DSP to your receiver or transceiver and begin using it on the air.
Connecting Power
Before you hook up to your computer, you need to connect power to your DSP. To prevent any potential accidents,
make sure your power supply is off and unplugged before connecting the DSP to a live power source.
(If you have a ready-made power supply, like AEA’s AC-4, insert the coaxial connector into the DSP’s POWER
receptacle, plug the “power cube” into the wall, skip this rest of the section and go to the
Turning it On section
below. DO NOT CONNECT YOUR COMPUTER YET.)
Locate the power cable in the accessory bag—the one that’s black but has a white strip running down the length of
one of its conductors—and strip off just enough insulation from the ends of both conductors to connect it to your
12-14 VDC
regulated power supply.
!
VERY IMPORTANT : your power supply must provide at least 12 VDC @ 1A under load to the DSP for it to
operate correctly.
Fasten the positive (+) lead—the one which has the white stripe running down its length—to the (+) terminal of
your power supply. Connect the other conductor to the negative (
−
) terminal of your power supply. Insert the
coaxial power plug into the POWER receptacle on the left rear of the DSP. DO NOT CONNECT YOUR
COMPUTER YET.
Turning it On
With the power connections made, turn on your power supply (or plug in the power cube into the wall outlet) then
depress the POWER switch on the front of the DSP. WATCH CLOSELY FOR THE FOLLOWING: the power
LED to glow, the ‘AU’ (AU stands for Autobaud) to light in the 7-segment Mode and Status windows, and the tune
bar LEDs to become active. If this occurs, then switch off the DSP and move on to the section,
Connecting Your
Computer to the DSP . If the above doesn’t happen, then go to Chapter 13 - Troubleshooting .
Note : If something other than ‘AU’ glows, the controller probably has been previously initialized and
should be reinitialized as described below.
