Summarize
With the large area, HD display time arriving, the LED display area usually will beyond
the sending card loaded area more, LED display project also is to realize by the way of
using many screens and processors. However, with the increasing of the processors, let
field control staff’s work also become complicated. For that, simplified site operation,
Unitech Dcdi 550 has multi-machine connection function. Multi-machine connection
function is as following: all machines recover to a certain work mode quickly,
namely "multi-machine loading template".
Connection type
On the left of the rear panel of Unitech Dcdi 550, there are two 3.5 mm headset
jacks, one marked as "TX" for the communications signals sent port; another is
"RX" as a communication signal receiver port. In order to achieve multi machine
connection, we need to connect all the machines according to the following
picture.
In the above diagram, the arrows represent 3.5 mm headset plug, and
communication signals are always from "TX" port sent to "RX" port. This is a
cyclic annular, its advantage is: A.
Any of Unitech Dcdi 550 can be a starting
point of the communication signal,
namely operating terminal can be arbitrary machine of the ring.
B.
Easily to add or remove one unit machine from the circular link structure.
