Low Power Mode
Setting Description
Notes
l Power savings occur only when the Slave radio is linked.
l No power savings occur when the Slave radio is transmitting data.
l Low Power Mode is of little value when a Slave has a constant, high
throughput.
l The MCU Speed parameter MUST be set to 0 and the RF Data Rate
parameter MUST be set to 3 for Low Power Mode to operate properly.
l To communicate to an RS-232 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 Request to Send (RTS) line on the Slave radio is held high, the radio
remains in normal operation regardless of the Low 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 77) parameter in the MultiPoint
Parameters tab 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
feature to operate properly.
l The diagnostic pins MUST be disabled or terminated to a cable for the sleep
current in Lower Power Mode to match the specifications.
l To disable the diagnostic pins, set these options:
l In the Baud Rate tab, the Setup Port (on page 38) parameter is set to 1
(Main Only).
l In the MultiPoint Parameters tab, the Diagnostics (on page 77)
parameter is set to 0 (Off).
3.9. Reading Diagnostics in Tool Suite
The Network Diagnostics application provides a place to view diagnostic data for all the devices
connected to the Master in the network in real time.
Important!: The Network Diagnostics application is NOT meant to replicate the functionality of a
Network Management System.
It is a tool intended for occasional network monitoring or troubleshooting in the field, not for
continuous, long-term collection of diagnostic data.
This section provides basic steps for reading diagnostics using Tool Suite. Tool Suite stores the
diagnostic data in the database for import from or export to a diagnostic file.
For information regarding the data available, recommended best practices, and importing and
exporting files using the Network Diagnostics application, see the Tool Suite User Manual
available in the Tool Suite software.
