Note that when TDD is enabled (TDD ON), there is a significant impact
on both data throughput and latency. Data throughput is roughly cut in
half. Worst case data latency is increased by two hoptimes. The effect in
seamless mode (
BUFF ON) is even more pronounced, as shown in Table
10.
TEMP
This command displays the internal temperature of the transceiver in
degrees Celsius. (Note that the radio is specified to operate in an envi-
ronment between –30 C° and +60 C°). This internal reading may be
higher than the outside temperature by several degrees.
TX [xxxx]
This command sets or displays the test transmit frequency used in place
of hopping whenever the radio is in Setup mode. The test transmit fre-
quency can be reprogrammed to any value between 902.025 MHz and
927.975 MHz, inclusive. The factory default settings are listed below
and have been selected to be non-intrusive to normal system operation.
UNIT [10000–65000]
This command sets the unit addressing for network-wide diagnostics.
The unit address is factory programmed to the last four digits of the
serial number. If re-programmed in the field, the entry must consist of
five digits between 10000 and 65000.
