NET™ Network Termination
The network must be properly terminated by a 120 Ohm resistor at the first and last reader of
the network.
5.6 AUXILIARY RS232 INTERFACE
The RS232 auxiliary interface is available for Point-to-Point, Pass Through or Master/Slave
connections. When it is connected to the host computer it allows both transmission of code
data and reader configuration by VisiSet™.
The parameters relative to the aux interface (baud rate, data bits, etc.) as well as particular
communication modes such as LOCAL ECHO can be defined through the Communication
folder of the VisiSet™ utility program.
The following pins of the 25-pin connector are used for auxiliary interface communication:
