The local network used by DS6400 exploits a Lonworks standard communication system
requiring only two wires (polarity insensitive) to enable a connection. The connector also
provides a positive and a negative supplying wire. In this way, all the slave readers can be
powered by the master through the Datalogic standard cables.
When working in applications requiring enhanced synchronization capabilities, the DS6400
master reader (output) transmits two system signals named Sys_I/O and Sys_Enc_I/O to the
slave readers (input). For example, when working with applications requiring an encoder the
signal is received by the master and directly transmitted to the slaves through the cable.
The internal circuits generating the system signals are externally supplied by means of the
VS_I/O and REF_I/O pins and are isolated from the reader supply voltage.
The use of these system circuits is not required in all the operating modes. Anyway, for
correct system functioning it is suggested to use Datalogic cables and accessories and follow
the description of the typical layouts (see chapter 7 for details).
