22.0 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) Quatech 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 43
and Table 44 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 43 and Table 44 use an AdHoc network. An infrastructure
network can be used as long as static IP configuration is used for the slave device.
