2.5.3 RS232
Master/Slave
The RS232 master/slave connection is used to integrate a DX8200A 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 C-BOX 100 (20 mA C.L. can also 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.).
NOTE
The
DX8200A Standard model
, working as Master in an RS232 network,
may be simultaneously connected to a Lonworks network consisting of
DX8200A 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).
