l For Low Power Mode to operate properly, the RF Data Rate (on page 45) must be set
to 3.
l To communicate to a TTL or RS232 port of a radio that is in Low Power Mode, the RTS
line MUST be held high to wake it up.
l The radio wakes up within approximately 20 milliseconds of when RTS goes high.
l If the RTS line on the Slave is held high, the radio remains in normal operation regardless of
theLow Power Mode setting.
l After RTS is dropped, the radio reverts to the Low Power Mode.
l If the radio has the DTR Connect (on page 65) parameter set to 1 or 2 and if the Low
Power Mode is enabled (set to 1 to 31), the RTS line on the radio must be asserted for
the DTR Connect to operate properly.
l Disable or terminate the Diagnostic pins to a cable for the Sleep current in Low Power
Mode to match the specifications.
l To disable the Diagnostics pins, verify the:
l On the Baud Rate tab, the Setup Port (on page 33) parameter is set to 1 (Main
Only).
l On the MultiPoint Parameters tab, the Diagnostics (on page 64) parameter is set to
0 (Off).
Conserve Power
Use Remote LED to conserve power by turning off the Diagnostic LEDs.
l If the radio has the optional 20-in connector, use Remote LED to connect remote LEDs
through the Diagnostics port.
l If the radio has the optional connector, use Remote LED to connect remote LEDs through
the Diagnostics port.
l To realize full power savings in Low Power Mode MUST have the serial port deactivated
between operation by asserting the RTS line.
l Conserves power primarily by dimming the radio's LEDs.
l However, because RS422 / RS485 operation uses the RTS line as part of the data bus, it
cannot be asserted to wake-up the radio.
FREEWAVE Recommends: Have all radios set to RS422 or RS485 use a Low Power Mode
setting of0 (Off).
4.4.4. Max Packet Size and Min Packet Size
Note: In MultiPoint networks, the Max Packet Size and Min Packet Size must be set identically in
all radios.
In Point-to-Point networks, the Master’s setting takes precedence over the Slave.
