Multi machine connection
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, LED-580F series processors
have 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".
Connect type
On the lower-left of rear panel of LED-580F series processors, there are two
RS232 series ports, one marked as"RS232/OUT"for communications signals
send port; another is "RS232/IN"as a communication signal receiver port. In
order to achieve multi machine connection, we need to connect all the
processors according to following picture.

In the above diagram, the arrows represent RS232series port communicate
cables, and communication signals are always from "RS232/OUT"port to
"RS232/IN"port. This is a cyclic annular, its advantages are :
A. Any of LED-580F series products 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.
