3. Unitoperation

Initialinspection

Priortoshipmentthisunitwasinspectedandfoundfreeofmechanicalorelectricaldefects.Upon

unpackingoftheunit,inspectforanydamage,whichmayhaveoccurredintransport.Theinspection

shouldconfirmthatthereisnoexteriordamagetotheunit,suchasbrokenknobsorconnectors,and

thatthepanelsarenotscratchedorcracked.Keepallpackingmaterialuntiltheinspectionhasbeen

completed.Ifdamageisdetected,fileaclaimwithcarrierimmediatelyandnotifyCAEN.Before

installingtheunit,makesureyouhavereadthoroughlythesafetyrulesandinstallationrequirements,

thenplacethepackagecontentontoyourbench;youshallfindthefollowingparts:

DT54xxdesktoppowersupplyunit

USBcable

Moreover,inordertooperatetheDT54xx,anexternalPersonalComputerisrequired.

Installation

ConnecttheDT54xxtothePCviatheUSBcable

DownloadandinstalltheUSBdriverforyourOS,availableattheDT54xxpageonthe

www.caen.itsite

NowtheDT54xxisreadyforoperation,uponinstallationofoneoftheavailabletools.

UnitControl

TheremotecontroloftheunitviaUSBcanbeperformedthroughoneofthefollowingways:

LabVIEWInstrumentDriver;seep.16
