9.5 Using the Radio's Sleep Mode (
In some installations, such as at solar-powered sites, it may be necessary to
keep Remote transceivers' power consumption to an absolute minimum. This
can be accomplished using the radio's Sleep Mode feature. Power consump-
tion in the sleep mode will be less at higher voltages and more at lower volt-
ages. Power in the Sleep Mode at 13.6 Vdc is approximately 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
tions are suspended until it is awakened. The radio stays in Sleep Mode until
a built-in one-minute timer "awakens" it for resynchronization, or the low is
removed 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 or less. The radio can be awak-
ened 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.
