DMX Mode
In this mode, dip-switch 10 is flipped to
ON
. Use the dip 1-9 to set the starting DMX address. The unit
needs one channel for control. The channel value determinates the volume for both channels at same time.
NOTE
: If the value is setting between 0%-10%, the unit is in Standby mode.
NOTE:
This channel controls the volume, therefore this value will indicate the percentage. For example, a DMX
value of 255 corresponds to 100% volume level, 127 corresponds to about 50%, etc.
Rs485 Mode
In this mode, dip-switch 10 is flipped to
OFF
. It has priority over analog control. The accepted command sentences
are:
#nnnVOL:INC=XX;CH=aa;\
Volume control
Where:
-
nnn
is the device address (between 1 to 511). If nnn=000 it is a broadcast.
-
XX
is the quantity of steps (between 1 to 255) to increase o reduce the volume (depending on the previous
sign + or -).
-
aa
can be CH1, CH2 or MASTER (for alter both channels)
#nnnSTB:\
The device turns to STANDBY mode. In this operation mode the consumption is minimum.
#nnnNOSTB:\
The device will return to normal operation.
#nnnAL:\
The device turns to ALARM condition. In this mode the volume will change to maximum and the analog control
will be disabled.
##nnnNOAL:\
The device leaves ALARM condition, returning to normal condition with the previous volume level.
0-10 V Control
This mode is always activated. When the value of the control signal varies, SLA take it this value as new volume
value. The value will be as reference until:
a) If the controller is operating in DMX mode and the DMX channel value changes.
b) If the controller is operating in RS485 mode and it receives a command will affect the volume.
NOTE
: Analog control will affect both channels at the same time.
NOTE
: Analog control will be disable if the unit receive an ALARM command through RS485 interface.
