INTRODUCTION

This rnanual is intended for use w th ihe GNIDSS A S test box model as well as for lheGN,4DSS-oniy model. Use|S oi the c [,1DSS-only rnode are kind]y requested to disfegardthe sections concernino AIS tests.

AIS lests

The test box s capable of tesl ing AIS kafsponders by mak ng f.equency measurements andpower measurements on CH 70, AIS channel 1 or AIS channel 2.

t is possible to check the GMDSS communication on CH 70 by requestjng repoding of Posit ion,Length, Course, Name/ldentity, Speed, Power or Ship's beam.

AIS communication is checked by sending data to an AIS transponder of receiving data from anAIS tfansponder.

The test box is also able to sirnulate a ship appearing at four different posit ions, relative to theA S transpondels posit ior 'r.

GMDSS fesfs

The test box can check DSC signals transmitted on any of the 6 d stress frequencies on MF/HFand on VHF CH 70 .

The test box can send either a Gl\,4DSS d siress signal (a sh ps ca l) of a selectlve test cal laddressed to a part icular NlNlSl number. The cal s can be sent on any of the 6 distresslrequenc es on I\,4F|HF as well as on VHF CH 70. Furthermore, the test box can seno anoreceive DSC signals on the internatiofa ca ing frequencies 2177.0 and 2189.5 kHz

The test box measures and d splays the mark/space frequencies of the received DSC-s gna s

When used as an ordinary frequency counter the test box measures frequencies in the range0.4 N/Hz to 475 N,4Hz.

On VHF CH 6 the test box can measure the deviat on on a received signa .

The test box is able to measure the transmitted and reflected power on any VHF channet, anoalso to iestthe sensit ivity ofthe receivef paft.

For the testing of Na\,,tex fecejvers, the test box can send Navtex signals on 490 kHz, 518 kHzar 4 .209 ,5 kqz.

The tesl box can also be used for contro of signals from EPlRBs, as i t can receive and decodetest cals on 406.025 / 406.028 / 406.037 MHz as we as receive the 121.5 [,4Hzsgnal.A measurements can be morl tored on the LCD display and results are stored n the lesl ooxrnemory froTn whefe t can be transferred to a PC for subsequent prlnt ng.

Watert ight and Crush Proof Case-- s cse is special ly configured to hold the tester and accessor es safe and secure. Weighta^ y 3.9 kgs. Extema d mensions: 486 x 392 x 192 mm.

POWER SUPPLYThe lest box has an intemal DC/DC switch mode power supp y that ca|l be connected directly loan external DC source of '15 - 28 V (+ on the center pin).

Furthermore, a wall plug power supply al ows the test box to be connected to '100 - 240 V AC,50-60 Hz.

The test box s equ pped with an internal rechargeab e 12 V battery. Whenever DC is connecledto the test box, the battery is charged. l f the DC supply is rer.oved, the internal batiery de iversDC to the test box and gives an unlnterrupied sw lch between external and iniernal DC supp y.

Before using the test box in the fe d, make sure that lhe nternal battery is ful ly charged.

When the iniernal bailery is close to being discharged this is indicated by a b nklng on the LCDdisplay and then, short y after this, the power is cut off so as not io damage the battery.

A power shuldown does nol nf uence data stored in lhe test box, as lhe data storage has aseparate back up battery.

POWER ON AND WARM-UPAfter power on, the software revision date is shown ln the LCD dispLay. The etter in the enddescribes the hardware version.

In the AIS RECEIVE mode you have a cholce between DATA, AlSl and AlS2.

SeLecting AIS 1 or AlS2 enables the test box to recejve and store one set of data on AIS 1 orAl52. Note, that l t may take up to 20 seconds unti the AIS transponder transmits i ts data.

Selecting DATA offers two fLther oot ons

CLR clears the iest box mer.ory of old AIS data.

RS232 sends the received AIS daia out on the RS232 connector (2400 Baud, B data bit. noparliy) and can be transferred to your PC via the RS232 cable supplied with the iest box.

In the sensitivity test mode, it is very important to use coax cables for the connection of theeouioment.

For reference, the test box RF output level is approx. -36.5 +A 2 dBm.

This test mode can also be used to simply check ifthe modulated signal is well received overthe air:

Ai VHF there is a choice between freqLlency measurements (FRQ) and feceivlng of DSC dala

At FRQ the test box waits unti l the VHF set is activated. The frequency is rneasured and shov'^on the LCD display. The frequency measurernent can be used boih for measuremeni of iheDSC signals frequency and fof measurement of un_rnodLl ated signals. Channe s that are c oseto CH 70 can also be measured ln this mode, provided that the signals have enough amp lLlde(approx -10 dBm). The measured frequenc es are stored n the memory.Ai DSC, the test box w I waii for a DSC call. A short press on any of the buttons can lnterruptthe walt ing state.Received DSC data is collected and a check is made to assu re thai the checksum is OK Staiusand MN,4S| number is shown on the LCD dlsp ay and is also stored in mernory, provided thal thechecksum is OK.

When perforrning EPIRB tests, a ways Lrse lhe self tesi mode on the EP RB. Doing so, theEPRIB wii l rad ate a single burst that is special ly coded to be gnored by the COSPAS-SARSATsvstem.

lf the EPIRB is accidenlal ly activated lf the en]ergency transm ssion mode, lhe test box wl Idisplay WARNING ALARN,4. Then, the EPIRB should be turned off at once and the false alerlreported to the neafest coast guard statlon or Search and Rescue centre.

.The lest box is very sensit ive to receiving EPIRB s gna s, so n most cases you sho! d nol L,sean antenna when lest ng EPlRBs. l f lhe display shows "P ease wa i", the lest box has detecte:the transn'r ission but is si i l l wa t ng for the rest to fo ow. l f nothing happens, i t is usua y beca!sethe signal is too strong or too week. Then, rnove the EPRIB closer or fudher away.

EPIRBS are available for taansmitl ing at various frequencies. So, in the EPIRB test mode thef rst step is to select frequency mode. Stading with 406.025 l\,4H2, pfess OK io prepare for iestsat this frequency, of press UP in order to move to 406.028 MHz and fudher on to 406.037 MHz.Pressing DOWN takes you io'121.5 MHz

lf the EPIRB does not provide any information of the ffequency, you are advised to begin w lh afrequency measuaement = FRQ (can be done at any of the frequency modes avai abLe) andthen select the correct frequency mode for the ful EPIRB tesi.

In lhe 406 MHz frequency modes there are the fol lowlng sub modes: FRQ, |\ ,4EAS and DATA.ln s!b mode FRQ, only freqlency and signal level are measured.

n sub mode MEAS the test box pedofms a ful test, measur ng frequency and s gnat evedur ng the lest transmission and recofd ng the dala str ings contained ln the kansm ssioa. Adata are aLrtomaticaly stored in ihe memory. Pressir'rg the DOWN buiion repealedly, the dalacan also be v ewed n the dlsplay, l ine by l ine.

In sub mode DATA you can choose whether the ast received EPIRB data are 10 be dtsplayedas HEX data or as ofd nary text. Then, press DOWN to view the data l lne by ne.

In the 121.5l\4Hz n]ode there rs a choice between ORD (Ordinary)and IMG (image)- Fifsi,select ORD and FRQ to measure the frequencV. Then seiecl IMG and FRQ 1o measure thefrequency again. Same resu l from both tests proves that the measured frequency ts correct andnot just an mage lfequency.Please note thal i t may not be poss b e to raake frequency measurernents of al l 12'1.5 MHzEPlRBs, astheANI modulation in some caseswi prevent this. l f so. se ect AF jnslead of FRQ.In the AF mode the nteanal loudspeaker is sw iched on and the AM modulaled s gnat can beheard during transmiss on. This pfoves that the EPIRB is transm tt ng on the correct frequency.Pressing any of the buttons term nates the AF mode.
