Sleep Modes and Connections
I/O Passing and Connections
Monitoring Connections
Cyclic sleep can be used with the remote modems to conserve power. ST “Time before Sleep”
Parameter defines how long after a disconnect a remote will stay awake. A modem is not allowed
to enter sleep mode when it is engaged in a connection. A modem will wake as defined by SM
parameter and check for an RF message. If a message is detected, the modem will stay awake
only if the message is a connect message from the base for this modem. DI3 (pin 2) wake-up can
be used to wake a remote modem. Usually the connection on DI3 should also be enabled so that
a connection is established on wake-up.
NOTE: The ST (Time Before Sleep) time must be set long enough to account for the time it could take
to make a connection if several remote modems get a connection before a remote’s ST times out.
Pin sleep can also be used with a remote modem. A modem will not be allowed into pin sleep
while a connection is active. Usually the connection on DI3 (DR = 4) should also be enabled so
that a connection is established on wakeup. Pin wake-up could also be used to scan for a
connection at an interval not defined by the cyclic sleep modes.
I/O lines can be passed between a remote and base modem by enabling I/O line passing (see the
RT, DR, CD, CO, CS, BK, BO commands). When a connection is not active, the output lines on the
base and remote modems will be in their default state. When a connection is established, the
base and remote output line will be set to reflect the corresponding input lines.
The DO3 pin (RX LED) can be used to show when a connection is active on both remote and base
modems. This is the default condition. This line will be asserted (high) during a connection and
de-asserted (low) when there is no connection.
A base modem can also be set to send the “CONNECT XXXX” string (where “XXXX” is the
connecting modem’s MY (Source Address) parameter) anytime a connection is established. Refer
to CM (Connection Message) Command.
