6.6 Using the Radio’s Sleep Mode (Remote Units Only)
In some installations, such as at solar-powered sites, it may be necessary to
keep a Remote transceiver’s power consumption to an absolute minimum.
This can be accomplished using the radio’s Sleep Mode feature. Power
consumption (current) in sleep mode will be less at higher input voltages and
more at lower input voltages. Power in the Sleep Mode at 13.8 Vdc is approx-
imately 3 mA.
Sleep Mode can be enabled under RTU control by asserting a ground (or
EIA/RS-232 low) on Pin 4 of the radio’s
DATA connector. All normal func-
tions are suspended until it is awakened by removing the low from Pin 4.
When Pin 4 is opened (or an EIA/RS-232 high is asserted), the radio will be
ready to receive data within 75 milliseconds. The radio can be awakened
more often if desired, by your RTU.
NOTE: The SLEEP function must be set to ON; without this, a ground on Pin 4 will be ignored.
