6.2 Idle-Mode
Some modes send a special DMX512A recommended frame on
DMX512 fail, the Idle-Mode. This mode serves to avoid a fault
status at the connected lighting devices by a faulty or missing
DMX512 line. The frame of the Idle mode only includes the
BREAK, MAB and START byte.
6.3 Valid frames
As "valid" a frame is described and reprocessed if a DMX start
timing was recognized after a DMX channel amount of max. 512
bytes.
6.4 Termination
At the end of a DMX512 data cable a 120
Ω
resistor has to be
connected. The SP1X12 does this for input A by a manual switch
indicated by a yellow LED.
Optimal wise one a data line basing on the RS485 interface
standard also should have a termination at the beginning. For this
reason the SP1X12 has a 120
Ω
resistance for every output.
