To implement "master-slaves" connection diagram the near located from 2- to 5- pcs.
E20-
10
can be connected with twisted pairs by shortest path. Similar circuits of all
E20-10
are required
to be connected implicitly (
: GND–GND, SYNC–SYNC, START–START. When
connections performing with twisted pairs one of the wire in pair should always be a GND circuit.
Connections optimal topology with short twisted pairs - is when two twisted pairs per each
"slave" go separate ways from "master" according to radial principle in shortest path, and non
optimal - is a sequential traversal topology. The compromise between the first and the second
variant is appropriate in practice. Short twisted pairs can be replaced with short screened wire
bridles (GND-screen).
The case of short connections of near located
E20-10
has been described above, but there is
a technical possibility to significantly increase the length of connections and the number of
synchronized
E20-10
. If you retransmit START and SYNC signals many times using transmitter
microcircuit from master
E20-10
(connector power + 5V) then the number of
E20-10
connected
according to "master-slaves" is unlimited technically! One of the examples of such connecting
based on MLVDS technology is described in L.[
