SIGNAL INDICATORS
The status of the Demultiplex Board is signalled with two LED indicators.
green:
operation (blinking)
red:
ERROR (blinking)
No error indication while normal operation
Error blinking at data errors or loss of communication.
1x green, 2x red:
Start address setting too high, not enough DMX data available to serve
all outputs.
1xgreen, 6x red:
Service routines active
CODING SWITCHES
The three decimal coding switches set the start address, that is the address of the first channel to
be decoded. The setting is fully decimal, no binary conversion is necessary as is with DIL switches.
S1:
Ones
S2:
Tens
S3:
Hundreds
If the switch block is set to address 000, all outputs are disabled regardless of the data received.
All settings made on the address board are retained in the demultiplexer internal nonvolatile
memory. The settings will remain active even when disconnecting the address board after the
setting has been saved. Do not detach the address board while the demux is saving configuration
data (both LEDs blink alternatively 4 times).
NOTE: We recommend to disconnect and to reconnect the address board only when the system is
fully powered down. Both printed circuit boards contain static sensitive electronic devices. Please
discharge yourself against GND before handling printed circuit boards. For maximum protection,
leave pcbs in the antistatic bag when not used.
