Switching threshold:

In DMX512 operating mode the start address is set at the three
rotary codes switches S1 to S3. The first channel starts with set
address, followed by channel 2, 3 and 4.
2.1.1 Switching threshold
All channels using different values for ON or OFF state. Two
thresholds are available.
DIP-switch S4.6 OFF:

ON State > 6 digits (3%), OFF State < 4 digits (2%)
2.1.2

Manual overwrite

To switch a channel ON by hand, independent by DMX512
control, use DIP-switches S4.1 to S4.4.
The LEDs K1 to K4 shows a switched on channel.
2.1.3

Hold last DMX512 frame

The latest valid DMX512 frame (all transmitted channels) is stored
continuously. In case of a lost DMX512 signal or faulty frames the
last values are held until the transmission continued.
This behavior could be disabled by setting DIP-switch S4.5 ON.
Now all channels will be switched OFF in case of an DMX error.
2.1.4

Termination

At the end of a DMX512 line it is recommended to connect a 120 Ω
1W resistor between data- and data+, here at the second terminal
block between the green and red clamps.
