RS232 MASTER/SLAVE

The RS232 master/slave connection is used to integrate a DS8100A reader in a network
consisting of different scanners not provided with a Lonworks interface.
The Slave scanners use RS232 only on the main and auxiliary interfaces. Each slave
scanner transmits the messages received by the auxiliary interface onto the main interface.
All messages will be transferred towards the master.
The master scanner is connected to the Host PC on the main RS232 serial interface through
the CBX connection box.
In RS232 Master/Slave connections the External Trigger signal is unique to the system
(single P.S.).
The DS8100A Standard model, working as Master in an RS232 network,
may be simultaneously connected to a Lonworks network consisting of
DS8100A slave scanners. Be careful when assigning the slave address,
since the number of the first Lonworks slave must be a progressive number
with respect to the address number defined for the last slave scanner of the
NOTE RS232 network. For example, if the RS232 network consists of Slave 1 and
Slave 2, the address to be assigned to the first Lonworks slave scanner will
be Slave 3 (not Slave 1).
