2.7.3 RS232 Master/Slave
The RS232 mas ter/slave connection is used to integrate a DS6300 reader (all models) in
network consisti ng of different scanners not provided with a Lonworks interface.
The Sla e scan v ners use RS232 only on the main and auxiliary interfaces. Each slav
scan ner tra nsmi ts the messages received by the auxiliary interface onto the main interface
All messages wi ll be transferred towards the master.
T he master scanner is connected to the Host PC on the main RS232 serial interface through
th e C-BOX 100 (20 mA C.L. can be used if the INT-30 accessory is installed).
In RS232 Master/Slave connections the External Trigger signal is unique to the system
(single P.S.).
The DS6300 master/slave scanner model (DS6300-10X-010 only),
working as Master in an RS232 network, may be simultaneously
connected to a Lonworks network consisting of DS6300 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 RS232 network.
NOTE
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).
