In RS232 Master/Slave connections the External Trigger signal is unique to the system

NOTE
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 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).
