XStream™ OEM RF Module – Product Manual v5.x00 [2006.02.24]
Note: If serial data exists in the DI buffer while the module is in
Receive Mode, the UART data will be transmitted after the module is
finished receiving the RF data and has returned to Idle Mode.
2.2.3. Receive Mode
2.2.4. Sleep Mode
If the module detects RF data while in Idle Mode, the module transitions into Receive Mode to
receive RF packets. Once a packet is received, the module checks the CRC to ensure that the
data was transmitted without error. If the CRC data bits on the incoming packet are invalid, the
packet is discarded. If the CRC is valid, the packet proceeds to the DO Buffer.
The module returns to Idle Mode when valid RF data is
no longer detected or after an error is detected in the
received RF data.

* Refer to the Addressing section [p36] of the
RF Communication Modes chapter for more information
regarding address recognition.
Sleep Modes enable the XStream Module to operate at minimal power consumption when not in
use. Three Sleep Mode options are available:
For the module to transition into Sleep Mode, the module must have a non-zero SM (Sleep Mode)
Parameter and one of the following must occur:
1.
2.
In Sleep Mode, the module will not transmit or receive data until the module first transitions to
Idle Mode. All Sleep Modes are enabled and disabled using SM Command. Transitions into and
out of Sleep Modes are triggered by various mechanisms as shown in the table below.

For more information about Sleep Modes, refer to the individual commands listed in “Related Commands”
column of the table. The SM command is central to all Sleep Mode configurations.

• Pin Sleep (Host Controlled)
• Serial Port Sleep (Wake on Serial Port activity)
• Cyclic Sleep (Wake on RF activity)
The module is idle (no data transmission or reception) for a user-defined period of time [See
ST (Time before Sleep) Command]
DI3 (pin 2) is asserted (only for Pin Sleep option)
Transition into
Sleep Mode
Microcontroller can shut down and wake
modules by asserting (high) SLEEP (pin 2).
Note: Module will complete transmission /
reception before activating Pin Sleep.
Automatic transition to Sleep Mode occurs
after a user-defined period of inactivity (no
transmitting or receiving of data). The
period of activity is defined using the ST
(Time before Sleep) Command.
Automatic transition to Sleep Mode occurs
in cycles as defined by the SM (Sleep
Mode) Command.
Note: The cyclic sleep time interval must be
shorter than the “Wake-up Initializer Timer”
(set by LH Command).
Transition out of
Sleep Mode
De-assert (low)
SLEEP (pin 2).
When serial byte is
received on the DI pin
(pin 4).
After the cyclic sleep
time interval elapses.
Note: Module can be
forced into Idle Mode
if PW (Pin Wake-up)
Command is issued.
