Introduction
WelcometotheFLEXtrainingprogram.TheFLEX‐LTisaself‐containedcontrol
systemwiththecapabilitiesofamuchmoreexpensivesystemandacostthat
everyonecanafford.TheFLEX‐LTmountsinawallorsitsonadeskandpresents
theuserwithaneasytouseandunderstandcolortouchscreen.Throughthetouch
screen,theusercanchoosewhatsourceisbeingdisplayed,changethevolume,
controlthevarioussources,turnlightsonandoff,raiseorlowertheshadesor
screenandmuchmore.

FLEXFrontPanel
YoucangainaccesstotheFLEXfrontpanelbyremovingtheplasticbezel.Thefront
panelhastwocommunicationports,RS‐232andminiUSB(forfutureuse).The
communicationportisusedtoloadconfigurationsintotheFLEXpanel.Belowthe
communicationportsisthehardwareresetswitch.TheFLEXpanelalsohasanIR
receiver(forfutureuse).Seethepanelillustrationbelow.
NOTE:TheUSBportandIRReceiverarecurrentlyinoperable.

FLEXBackPanels
ThebackpaneloftheFLEXsystemhousestheconnectorsforbothcommunication
andpower.TheEthernetportusesastandardRJ‐45connection.Allother
connectionsuseaplug‐ablescrewterminalstyleconnectorfordevicewiring.The
imagesbelowillustratetheconnectionpanelsfromtheLT100,LT‐200andLT‐300
FLEXsystems.

InstallingtheFLEX

Mounting
The FLEX-LT should be installed in a 2-gang enclosure such as a Carlon plastic two-
gang device box. The unit should be positioned so that both the user and installer can
conveniently operate LCD touch plate. This is usually a wall or a desktop. If a desktop
installation is required, use an FSR DSKB-2 desktop console.

Check the recommendations on cable requirements and termination for any external
devices connected to the Flex. Use standard approved wiring practices.
The integrity of all cables should be pretested BEFORE they are connected to the FLEX-
LT. This holds true for the external cabling as well. Simply direct connect the various
sources and displays to pretest the cable runs and equipment. All terminations should
have "ID" cable markers to aid in cabling and troubleshooting.
WiringtheFLEX

NOTE:ThewiringfortheFLEXLT200andtheLT300areidentical.TheLT300does
nothaveaseparateserialportforloadingprojects.ConnectcableprovidedinFLEX
ProgrammingKittoSERIAL2asillustratedbelowtoloadprojectstoaFLEXLT300.

Power
TheFLEXcontrolpanelispoweredwitheithera12Vpowersupply(included)or
poweroverEthernet(PoE).
Tousethepowersupplystripbothconductorsback¼”in.andinsertthestriped
wireinthe+receptacleofthepowerconnector.Thepowersupplyhasa9ftcable.
Thepowercablecanbeextendedupto50feetwitha22gauge2‐conductorcable.
TheFLEXsystemalsohasconnectorsfora3VAAAbatterybackup.Anoptional
batteryholderisavailable.Makeallpowerconnectionsasshownbelow.


TheFLEXcontrolpanelisalsoaClass1POEEthernetdevice.Class1requiresa
rangeofpowerwithaminimumof0.44wattstoamaximumof3.84watts.Besure
thatthepowersuppliedovertheEthernetnetworkadherestothesespecifications.
Serialconnections

TheFLEXLT–200hasfourserialconnectorsonthebackpanel.Theconnectionsare
madeusingplug‐ablescrewterminalconnectors.Tomaketheconnection,stripthe
wiresasneeded.TheFLEXcontrolpanelhasawiringdiagramontherearpanel.
Wireeachpluggablescrewterminalconnectorasillustratedbelow.Eachpairof
serialconnectionssharethecenterconnectorasgroundwithRXandTXconnected

TheFLEXcontrolpanelusesstandardSerialprotocols.ThestandarddistanceforRS
232communicationis50feetusing22ga.three‐conductorcable.FSRrecommends
theuseofWestPenn230seriescommunicationswireorsimilartoensureproper
signaltransmission.
IRConnections
TheFLEXsystemshipswithtwoIRtransmitters.TheFLEXLT‐200systemcan
poweruptofourunitsontheLT200unitsand2ontheLT100.Usingquality22‐
gaugetwo‐conductorwiretheIRtransmitterscanbeplacedupto100feetaway
fromtheFLEXpanel.TransmitterbudsshouldbeplacedinfrontoftheIRreceiving
windowofthedevicetobecontrolled.Eachpluggablescrewterminalconnectorwill
power2IRtransmitters.Eachconnectorhas2inputsforeachofthe(+)wires.The
groundconnectorisshared.

GeneralPurposeI/O
TheFlexhas4GPIOports.Itisimportanttonotethatthesearedifferentfromdry
contactclosuresanddonothavethesamefunctionality.TheGPIOportscanbe
configuredasInputsorOutputs.AsanInput,avoltageof2.4VDCto24VDCwill
readasa1whileavoltagebelow+1.0VDCwillreadasa0.WheninterfacedtoTTL
orCMOSlogic,theFlexinputsaredirectlycompatible.Wheninterfacedtoan“open
collector”typeoutputornormallyopencontactclosurethatisactivehigh,make
surethatitisatleast2.4VDCanddoesnotexceed24VDCwhen“on”.Additionally,if
usingan“opencollector”typeoutputthat“leaks”morethan0.1mA,apull‐down
resistormayberequiredtokeeptheFlexinputbelowthe1.0VDCwhenthesource
is“off”.Ifyouareinterfacingtoan“opencollector”ornormallyopencontact
closurethatisactivelow,attacha“pull‐up”resistorof1Kto10Kohmsbetween
yourGPIOpinandtheV+inputoftheFlex.Thiswillholdthepinhighuntilyour
