nRepeater control command

RepeatercontrolisachievedbysettingtheFOURTH
CHARACTERoftheparameterto“+”.
Example:
VOLM030+ ← Setsvolumeofallmonitorsto30.
In repeater control, responses are returned by all the
connected monitors.
If you want to determine that a value has been returned by a
specicset,assignIDnumberstoeachmonitorinadvance.
Whensomemonitorsdonotreturntheirresponses,the
probable cause is that the monitors could not receive the
commandorcommandprocessingisnotcomplete.Donot
send a new command.
Example: (When4monitorsareconnected,and
assignedIDnumbers:1through4)
VOLM030+
WAIT
OK 001
OK 002
OK 003
OK 004 ← If 4 monitors are connected in
a chain, reliable operation can
be ensured by sending a new
command only after a reply
hasbeenreturnedby4th(last)
monitor.
Repeater control can also be used for reading settings.
Example:

nTo transfer the GAMMA user data

Usetheuserdatatransfercommands(UGRW,UGGWand
UGBW).ForeachoftheR,GandBcolors,dividethetotal
512piecesofuserdatainto16blocks,andtransfer32pieces
of data with each command.

nSaving the GAMMA user data

Usetheuserdatasavecommand(UGSV)tosavethe
transferred user data in the monitor.
If the data is not saved, it will be cleared when:
• Themainpowerswitchisoff
• STANDBYMODEisLOWPOWERandthemonitorenters
standby mode

nActivating the GAMMA user data

Toactivatethetransferreduserdata,selectUSERforGAMMA
ofthePICTUREmenu,orsendthecorrespondingRS-232C
command.

nChecking the GAMMA user data

Usetheuserdatareadcommands(UGRR,UGGRand
UGBR)toreturn512piecesofuserdataforeachoftheR,
GandBcolors.Dividethedatainto16blocksandreturn32
pieces of data with each command. The value to be returned
is not the value stored in the monitor, but the value in the
temporarymemoryfordisplay.(Thesevaluesarethesame
whentheuserdatasavecommand(UGSV)abovehasbeen
sent.)
TIPS
• TheuserdataisnotinitializedbyRESETofthePICTURE
menu.Toinitializetheuserdata,useALLRESETofthe
FUNCTIONmenu.
TheGAMMAuserdatainitializecommand(UGRS)allows
