2-way DMX merge
The Showtec DMX Merge allows you to combine two DMX controllers to one DMX line or to use a second desk as back-up desk.The unit has 3 modes:1) HTP (High Take Precedence) In this case you can use two similar desks with the same  addressing on one line. The DMX channel with the highest value has priority.2) Back-up mode. The unit is connected to two DMX desks. Channel A has priority.  Once channel A fails or has no DMX channel B takes over the show.3) Merge mode. Two desks can be merged on one line. E.g. you can run a scene setter  and DMX operator on one line. The Scene Setter will operate on channel 1-96 and the  DMX Operator will have the channels 97 and higher. These positions can be freely addressed  by the dip-switches.
