REPLACING A SERIAL CABLE
The serial device servers can be configured to act as a cable replacement using either an AdHoc or
infrastructure network. In this application, you will need two (2) B+B SmartWorx Serial Device Servers.
Once configured, the two devices will automatically connect and make a virtual serial connection
between the two serial ports across the 802.11 network.
To establish the cable replacement, one device will be the Master and one the Slave. It does not matter
which end of the serial connection is which. The master initiates the network connection and the slave
waits for the master to connect. The following Table 40 and Table41 identify the required configurations
for the master and slave. The configuration is for a single serial port; the same configuration can be
used with those devices that support two serial connections.
The configurations in Table 40 and Table 41 use an AdHoc network. An infrastructure network can be
used as long as static IP configuration is used for the slave device.
