DSTS-5A User's Manual
1 PACKING LIST
1.1 The following items a e included with the DSTS-5A:
1.1.1 Powe t ansfo me . A 9VDC 300mA wall plug powe adapte is supplied.
Nominal powe equi ements a e 8 to 12 volts at 200 mA.
1.1.2 A CD with softwa e fo cont olling, calib ating, and updating the DSTS-4A.
1.1.3 A use 's manual.
2 OVERVIEW
2.1 The DSTS-5A is a compute cont olled depth sounde test set with fish echo emulation.
All functions such as eply level, depth, and width fo the fish and bottom echoes a e
cont olled by data sent th ough the RS-232 po t. The included p og am “DSTS-5A
Vx.xx.exe” o any te minal p og am may be used to cont ol the DSTS-5A.
2.2 OPERATING THE DSTS-5A WITHOUT A COMPUTER
2.2.1 When powe ed up without the RS-232 connection the DSTS-5A will ope ate in
the Q-mode, allowing a depth sounde to be evaluated based on the t ansmitte
powe and eceive sensitivity. The Q-mode gene ates an echo based on
t ansmitted powe and depth. The depth is inc emented by one foot and the eply
level is dec eased each time the depth sounde t ansmits a pulse. As the depth
inc eases a point will be eached whe e the echo is no longe eceived. The quality
of the depth sounde can be ead f om the maximum depth eading befo e the echo
is lost.
3 CONNECTING THE DSTS-5A TO A COMPUTER
3.1 To install the supplied softwa e, copy the file “DSTS-5A Vx.xx.exe”to a di ecto y of
you choice. To un the
p og am, click on it and it
will launch. You must have a
se ial po t o USB/se ial
adapte to use this p og am.
3.2 Connect the DSTS-5A to the
compute using a standa d 9
pin RS-232 cable. Connect
the wall t ansfo me powe
supply. Status LED 2 will
light fo six seconds and the
status LED's will sequence
one time. Afte powe -up the
status LED 3 will glow and
pulse at a one-second ate indicating the DSTS-5A is eady fo ope ation.
DSTS-5A Manual Page 2 Rev 140930-300

3.3 Run the “DSTS-5A Vxxx.exe” p og am. If the com po t and RS-232 connection a e

depth sounde . To ve ify the connection, click the “ eset” button. If the connection is
good, the softwa e ve sion will appea b iefly in the input f equency display box.
4 CONNECTING A DEPTH SOUNDER TO THE DSTS-5A
4.1 Connect a depth sounde to the IN/OUT connecto . Do not connect depth
sounder to the Trig Out connector or the DSTS-5A will be damaged. If the
depth sounde has a balanced output, one of the two inne wi es will need to be
connected to the shield and g ounded. Consult the manufacturers manual to determine
if one wire and the shield can be used as ground without damaging the depth sounder.
If you a e unsu e of the co ect
connections fo a balanced output,
use the EDI BAL-550 accesso y.
The BAL-550 is a balanced-to-
unbalanced t ansfo me that has
connections fo the shield and two
wi es. The output of the BAL-550
connects to the DSTS-5A.
4.1.1 Apply powe to the depth
sounde . When the sounde
t ansmits, the ed status LED
will blink indicating that a
pulse has been eceived.
4.1.2 The input cha acte istics of the eceived pulse a e displayed on the uppe g oup
of boxes and t ansmitted echo signals a e displayed in the lowe g oup. The esults
a e updated each time the DSTS-5A eceives a pulse o once a second if no pulse
has been eceived. If the depth sounde is disconnected, the input pulse
cha acte istics will still display and will not change until a new pulse is eceived.
P essing the “ eset” button will eset the DSTS-5A and clea the input g oup of
displays.

mete s pe second. These values a e sto ed in eep om and may be changed if desi ed.
5.6.1 Fo met ic calib ation fi st choose the met ic mode by typing “cm”followed by
'ente '. Then type a lowe case 'v' followed by the desi ed Vp op in mete s/sec. Fo
example, to set Vp op to 1502 mete s/ second type “v1502” and 'ente '.
5.6.2 Fo setting Vp op in feet fi st choose the foot mode by typing “cf”followed by
'ente '. Then type a lowe case 'v' followed by the desi ed Vp op in mete s/sec. Fo
example, to set Vp op to 4915 feet/second type “v4915” and 'ente '.
5.6.2.1 FISH ECHO GENERATION
5.6.2.1.1 The DSTS-5A is capable of gene ating a seconda y echo between the
su face and bottom. This echo can be used to simulate an echo f om a fish
o othe object above the bottom and will be efe ed to as a fish echo. The
depth, width, amplitude, du ation and a ch shape of the fish echo can be
set. The du ation of the fish echo is set by specifying the numbe of echoes
that the fish will gene ate as it passes unde the t ansduce . A mo e ealistic
fish echo can be gene ated by specifying a depth inc ement. The depth of
the fish echo is dec eased fo half the du ation then inc eased fo the
emainde of the du ation. If the inc ement is set to ze o the fish echo will
emain at a constant depth du ing its du ation.
5.6.2.1.2 SETTING UP A TYPICAL FISH ECHO
5.6.2.1.2.1 Set the bottom depth to 25 feet by typing “d250 'ente '”. Set the
fish depth to 23 feet by typing “D230 'ente '”. Set the fish echo off time
to 20 pulses by typing “e20 'ente '”. Set the fish on time to 3 pulses by
typing “E3 'ente '” and the fish echo will appea fo 3 pulses eve y
twenty pulses and epeat until disabled by typing “e 'ente ”.
5.6.2.1.2.2 The amplitude of the fish echo can be set using the “L”
command.
DSTS-5A Manual Page 5 Rev 140930-300

5.6.2.1.2.3 The width of the fish echo t acks the width of the pulse f om the
depth sounde in the auto-t ack mode. It can be manually set using the
'Wxxxx' command. Fo example, “W200 'ente '”will fix the fish echo
width at 200 uSec.
5.6.2.1.2.4 To make the fish echo stay on continuously type “E 'ente ' ”.
Type “e 'ente ' ” to tu n the fish echo off.
5.6.2.1.2.5 To gene ate a fish a ch use the “i” command to ente an value in
tenths of the selected units ep esenting the a ch height.
5.6.2.1.3 CHIRP ECHO OPERATION
5.6.2.1.3.1 A chi p can be gene ated as a eply fo the fo the bottom echo.
This chi p is a linea f equency vs. time type. Inputs a e the sta t
f equency, f equency step, step size, and the dwell time fo the
f equency step. When the bottom echo occu s, it will sweep f om the
sta t f equency th ough the numbe of steps.
5.6.2.1.3.1.1 The ending f equency will be equal to sta t f equency +
(numbe of steps * step size).
5.6.2.1.3.1.2 The du ation of the chi p will be the numbe of steps *
dwell time. Note that minimum dwell time is about 5 uSec.
5.6.2.1.3.1.2.1 The dwell time is dependent on othe facto s such as
f equency so fo maximum accu acy we ecommend using an
oscilloscope to check the echo du ation.
5.6.2.1.3.2 Ente the chi p menu by typing 'h'. A sub-menu appea s and the
dwell time, sta t f equency, step size, and numbe of steps may be
ente ed. When the desi ed values have been ente ed type uppe case 'X'
to leave the chi p sub-menu and etu n to the -5A command menu so
depth, amplitude, etc. can be set. Note that typing 'X' does not stop the
chi p mode, it only exits the sub-menu.
5.6.2.1.3.3 To stop the chi p echo mode and etu n to no mal ope ation,
type an uppe case 'H'. To e-sta t the chi p type 'h' and the p eviously
ente ed chi p settings will be used. These settings a e not etained when
the powe is tu ned off.

6 CALIBRATING THE DSTS-5A
6.1 The load esisto can change if ove heated by too much powe . A la ge change in the
esistance will cause the voltage and eply eadings on a depth sounde to change. The
load esisto should be checked any time abno mal eadings a e expe ienced.
6.1.1 Check the load esistance with the DSTS-5A powe off. Place an ohmmete
ac oss the IN/OUT connecto . The esistance fo the facto y installed load should
be 582 ohms +/- 10%. The esistance of a custom load at the IN/OUT connecto
should ead 22 ohms highe than the value of the installed load esisto . If the load
is out of spec, the unit should be taken apa t and the load esisto eplaced befo e
any fu the calib ation o checks a e done.
6.1.2 Run the supplied te minal p og am, DSTS_te minal.exe.
6.1.3 VOLTMETER CALIBRATION
Caution—Do not perform this procedure without a EDI DSTS calibrator
or other comparable pulse source.1
6.1.3.1 The volt mete calib ation is in the “extended menu”. Type 't' to ente the
extended menu. Then type 'c' to sta t the voltmete calib ation outine. Connect
the EDI DSTS calib ato o othe compa able pulse sou ce to the IN/OUT
connecto . Afte the indicated voltage eadings have settled down, type in the
co ect input pulse voltage in volts peak-to-peak and p ess 'ente '. A calib ation
facto will be gene ated and sto ed in eep om. P ess the eset button and check
that the voltage eads co ectly. If not, epeat the calib ation.
6.1.4 FREQUENCY CHECK
Connect the DSTS-5A to a f equency counte and p ess the eset button. Set the
output to continuous by typing ‘B’ followed by ‘ente ’. Set output level to
maximum by typing l255. Set the f equency to 100 KHz by typing f10000 followed
by ‘ente ’. The f equency counte must ead 100,000Hz +/- 10 Hz.
6.1.5 REPLY AMPLITUDE CHECK
6.1.5.1 Connect a scope (1 megohm input equi ed) di ectly to the IN/OUT
connecto with a sho t (< 3ft) cable. Set the f equency to 100 KHz (f10000) and
the level to maximum (l255). The voltage must ead 140 mV p-p +/- 7 mV p-p.
This is a fixed facto y setting and will not change unless the DSTS-5A has been
damaged by a seve e ove load.
6.1.6 OPTIONAL REPLY ATTENUATOR CHECK
6.1.6.1 Connect the DSTS-5A IN/OUT connecto to a spect um analyze . Set
va ious levels to make su e the attenuato t acks p ope ly. Note that the output
on the analyze will be low because the 50 ohm input impedance of the
spect um analyze loads down the DSTS-5A output. If a high impedance
(>=100,000 ohm) p obe is available, the eadings will be co ect and a level of
1 The EDI DSTS Calib ato p oduces a 400 volt p-p pulse bu st with a f equency of 204.8 KHz, length of 325 uSec,
and a pe iod of 80 mSec. D oop is less than 10 pe cent.
DSTS-5A Manual Page 9 Rev 140930-300

255 will p oduce 50 mV ms. Each dec ease in the level will educe the output
by 0.3 dB. The object is to ve ify that the attenuato is ope ating p ope ly.
The e a e no adjustments.
7 SO TWARE UPDATES
7.1 The DSTS-5A softwa e can be updated via the RS-232 connection. As softwa e
featu es a e added, pe iodic update files may be sent via email. They can be installed
in the DSTS-5A by using the supplied p og am, “p ogdsts.exe”.
7.1.1 Put the p ogdsts.exe, update.bat, and the updated DSTS-5A.hex file in the same
di ecto y. The illust ations assume the p og am and hex file a e in the c:\ di ecto y.
7.1.2 P ess the eset (RST) button on the DSTS-5A and immediately un the update.bat
p og am. Note that afte a RST, status led 2 stays on 5 seconds, then goes off.
You must sta t the update.bat p og am while the status led 2 is on fo the update to
wo k successfully.
7.1.3 If the update is unning successfully you will see the following sc een:
7.1.4 Afte the update, the above sc een will close and the DSTS-5A will begin
ope ating with the new softwa e. It is not necessa y to eset the DSTS-5A afte an
update.
