4) Total System Data Throughput Selection
This is the total over-the-air data transfer capacity of a
system, in both directions (inbound plus outbound). For the
SR-7100 System, this is 96, 240, or 512Kbps.
5) Set Base Frequency
This is the system center radio frequency. Depending on the
data rate, there are a different number of frequency channels
available for operation. For the highest data rate, there are
five non-overlapping channels that can be operated. (See
Appendix A for a list of frequency values.) Type a value and
press the Enter key. You will be returned to the Network
Control Unit Setup menu.
6) Set Output Power Index
This is the power level for radio transmissions from the NCU.
Options are 0 – 63, with 0 representing minimum power as
allowed by the FCC for each data rate, and 63 representing
full power. Type a value and press the Enter key. You will be
returned to the Network Control Unit Setup menu.
In our example, select Set Base Unit Frequency to set it to
frequency 4, and select Set Output Power Index to set it to
63.
