195Es FREQUENCY OF OPERATION
In a wireless Ethernet network all of the ESTeem Model 195Es’s must be set to the same radio frequency of operation or channel.
Listed on the right is a table showing the channel and corresponding frequency of operation. The frequency of operation is
selectable when configuring the mode of operation of the 195Es (reference Chapter 4). See Figure 1.
RF COMMUNICATIONS DATA RATE
The RF data rate of the Model 195Es can be programmed for operation at 48, 96,192 or 384 Kbps. The RF data rate can be set for
a fixed rate or a specific range that is dynamically scaled by the Model 195Es from monitoring the received signal quality.
Dynamic scaling means that the Model 195Es will operate at the highest RF data rate that is programmed into unit. If the
received data quality drops below the required minimums for reliable communications the Model 192E will reduce the data rate to
the next lowest step to increase signal quality. Conversely if the signal quality increases above the minimums the Model 192E
will increase the RF data rate the next highest level.
