2.7.3 RS232 Master/Slave
The RS232 master/slave connection is used to integrate a DS6500 reader (all models) 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 C-BOX 100 (20 mA C.L. can also be used if the INT-60 accessory is installed).
In RS232 Master/Slave connections the External Trigger signal is unique to the system
(single P.S.).
NOTE
The DS6500 master/slave scanner model (DS6500-10X- 010 only),
working as Master in an RS232 network, may be simultaneously
connected to a Lonworks network consisting of DS6500 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.
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).
