Easywave

AnoptionalEasywavereceivermodulecanbemountedinsidethePM1122‐INT.AneightbuttonRF
switchcanbeassignedtoazoneofthePM1122.



4buttonsnamedAtoDareusedforselectingthesourceortorecallapreset.Bydefault,thesebuttons
areusedtoselectsourceAtoD.Nexttothatareanupanddownbuttoncontrollingthemusicleveland
finallythesame2buttonscontrollingthemicrophonelevel.

AssigninganRFswitchisassimpleaspushingthe“Learn”buttonfromthecorrespondingzone(x)and
thanpushinganybuttonoftheRFswitchwithin5seconds.IncasethePM1122‐INTisinalessaccessible
place,thiscanalsobedonebyanRS232instruction.“LRNRFKEYZONEx\n”hasthesameeffectas
pushingthe“Learn”buttonfromzonex.Clearingthememoryorun‐assigningtheRFswitchesalsocan
bedonein2ways:pushingthe“Clear”buttononthePM1122‐INTforatleast2secondsorbythe
instruction“CLRRFKEYALL”.

Assigningthefirst4buttons(AtoD)fromzonextoapresetcanonlybedonebythefollowing
instruction:
SETRFKEYZONExPRESET\n

Thepresetsthatarerecalledare1to4iftheswitchisassignedtozone1or7to10iftheswitchis
assignedtozone2.

Toputitbacktoselectthesources,nextinstructionneedstobeexecuted:
SETRFKEYZONExSELECT\n

There’salsoafeaturethatbothmusicasmiclevelcanbeputatminimumbydoubleclickingthevolume
downbutton.Thisfeatureisenabledby“SETDOUBLECLICKON\n”ordisabledby“SETDOUBLECLICK
OFF\n”.

Presets

Apresetisasetofstoredvalues.ThesevaluesareMusicLevel,MicLevelandSourceSelectionforzone
1and/orzone2.Apresetcanbestored,recalledorcleared.Theonlywaytostoreapresetisbyusing
theRS232interface.Apresetcanberecalledusingthesameinterface,usingthecontactsattheback
sideofthePM1122orwithanEasywaveRFswitch,ifbuttonsAtoDareassignedaspresetselector
knobsinsteadofsourceselectors,asdescribedearlier.

Preset0canonlyberecalled(cannotbeoverwritten)andthiswillsetalllevelsattheminimumand
sourceselectionsatsourceA.Itcanonlyberecalledbytheserialinterface.

StoringapresetwillcopythecurrentsettingstotheinternalmemoryofthePM1122‐INT.Itispossible
tosaveonlythesettingsofonespecificzone.Afewexamples:
•“STRPRESET2\n”willstoreallsettingstopresetnumber2forzone1ANDzone2.
•“STRPRESETZONE13\n”willstorethesettingsofzone1topreset3.Whenpreset3willbe
recalled,onlyzone1willchange.

ApresetcanbeoverwrittenbystoringatthesamepresetnumberorclearedbytheCLRcommand.

Recallingapresetwillchangethevaluestothoseofthecorrespondingmemorylocation.Againafew
examples:
•“RCLPRESET2\n”willrecallthesettingsasstoredinpreset2(e.g.ifthepresetisvalidforboth
zones,thenthestoredsettingswillbeappliedtoBOTHzones).
•“RCLPRESETZONE20\n”willputthelevelsofzone2totheminimumandsourceofzone2to
“A”.
•“RCLPRESETZONE11\n”willapplythepresetnumber1settingstozone1only,evenifthe
presethasbeenstoredasazone1and2preset.

PresetscanalsobeselectedbyconnectingwiredremotesusingthecontactsCOMAanBandthe
contactslabeled1to6.Theyarepresentatthebackoneuroblockconnectors.
AfirstpresetselectorwiredtoCOMAandtocontacts1to6willenableyoutorecallpresetsnumbered
1to6,whereCOMAisthecommonwireontheselectorandcontacts1to6arethecontactsoperated
bytherotaryselector.
AsecondpresetselectorwiredtoCOMBandtocontacts1to6willenableyoutorecallpresets
numbered7to12.
Pleasenotethatyoucanspecifywhetherornotthepresetsselectedbythewiredselectorsarebeing
selectedatpowerupwiththe“SETROTARYATSTARTON”or“SETROTARYATSTARTOFF”setting.
