PORTS, MERGING, PRIORITY AND DMX INPUT
PORTS AND MERGING
Each DMX Port is fully independent which allows for configurations including setting multiple ports to the same universe. A
commonly used configuration for eDMX2 PRO is 2x isolated DMX512 outputs of the same universe, thus turning the eDMX2 PRO
into a USB DMX or 1 universe Art-Net/sACN node + 2 port isolated splitter in one.
DMXking products are capable of several advanced merging and stream selection functions usually only found on high end
equipment. Support for both HTP (Highest Takes Precedence) and LTP (Latest Takes Precedence) merging of 2 sources producing
a single DMX512 output thus permitting 2 controllers to co-exist for 1 lighting rig. To achieve DMX stream merging simply send 2
Art-Net or sACN streams with the same Universe ID and configure the applicable merge scheme HTP or LTP. If the number of
sources exceeds 2 only the first 2 will be processed and all others are dropped. Possible merging sources are:
Source
Notes
Art-Net I, II, 3 or 4
Priority 100 is assigned to permit Art-Net + sACN merge/priority functionality.
sACN / E1.31
Only sACN sources of the same Priority will be HTP or LTP merged.
DMX In Art-Net
Configure DMX In port universe to the same as DMX Out port universe. Priority is 100.
DMX In sACN
Configure DMX In port universe to the same as DMX Out port universe. Priority is defined by
the Discovery Period slider (values of 0-200 valid).
USB DMX
Source is Universe 1 Priority 100. Note if using 2 universe USB DMX mode 2
nd
is Universe 2.

Notes
Art-Net
Art-Net
Sources are timed out 3 seconds after last received frame.
sACN / E1.31
sACN / E1.31
Sources will end immediately upon sACN stream termination flag, otherwise 3 second
timeout after last received frame.
Art-Net
sACN / E1.31
Art-Net source timed out 3 seconds after last received frame, sACN stream termination flag
otherwise 3 second timeout after last received frame.
DMX In
Art-Net
Merge external DMX512 source (i.e. console) with incoming Art-Net stream.
DMX In
sACN / E1.31
Merge external DMX512 source (i.e. console) with incoming sACN stream.
USB DMX
Art-Net
Sources are timed out 3 seconds after last received frame.
USB DMX
sACN / E1.31
USB DMX source timed out 3 seconds after last received frame, sACN stream termination
flag otherwise 3 second timeout after last received frame.
USB DMX
DMX In
Merge external DMX512 source (i.e. console) with USB DMX source.
SACN / E1.31 PRIORITY
At any time if a higher priority sACN stream is received it will take over control a DMX Out channel regardless of other incoming
streams or merging. When an sACN stream is stopped gracefully via a stream terminate message the eDMX2 PRO port will
immediately revert to whatever other sources are present, otherwise the default stream timeout of 3 seconds applies. If you
want to HTP/LTP merge 2 sACN streams together they must be of the same priority.
