9.2.3 Awake Timer Register (addr = 6-7)

The Awake Timer register contains the time value the XBee radio will remain awake after the Deep-Sleep timer has expired.

Minimum time for this register is 6 (12 seconds). Incoming messages to the sensor will reset this timer extending this awake

period and allows long messaging such as waveform retrieval to be passed before the sensor goes back to sleep. The resolution

for this 2-byte register is 2 seconds with the LSB at location 6 and the MSB at location 7. This function will be ignored if the

Deep-Sleep Timer is set to zero and the sensor will operate in the Manual mode as described below. If the Awake Timer is

programmed to be longer than the Deep-Sleep Timer, a fault will be indicated in the Status1 byte message and bit 0 will be set in

the Error Indicator Register (section 9.2.7). On error, both of the Deep-Sleep and Wake Up timer registers will be replaced with

the default values (see Section 9.1).

9.2.4 Outgoing Message Mode Register (addr = 8)

The Outgoing Message Mode register contains the value on the method the sensor will send Outgoing Messages when it wakes up

from Deep-Sleep. The table below indicates the operating mode based on this register value. This function will be active when

the Deep-Sleep register (4-5) is non-zero. If the application expects the gateway to drop the sensor from its device table, it is

recommended Auto Send 2 messaging be used with a minimum value for the Awake Timer set to 12 (24 seconds). The gateway

may not receive the 1

st

sensor message as it is attempting to associate itself with the gateway, but the 2

nd

copy should be received.

See section 8.2.1.2 for the outgoing message format. See section 9.2.10 for limiting the # of Event Blocks within the message.

Reg Value Message Mode Operation after waking up from Deep-Sleep

0 Manual Sensor will only send messages upon request during the Awake period (default setting).

1 Auto Send 1 Sensor will send a single Command 1 message containing up to 8 blocks of recorded Event Data

and will wait for the entire programmed Awake Time for any normal protocol requests. There is

no demand for any acknowledgement and no retry will be sent.

2 Auto Send 2 Sensor will send a single Command 1 message containing up to 8 blocks of recorded Event Data

and will wait for ½ the programmed Awake Time then sensor will send a second copy. Awake

Time will continue in its entirety for any normal protocol requests. There is no demand for any

acknowledgement and no retry will be sent.

3 Auto Send 3 Sensor will send a single Command 1 message containing up to 8 blocks of recorded Event Data

and will wait for ½ the programmed Awake Time for a protocol acknowledgement (Command

200). If acknowledge message is not received within ½ of Wake up Time, then a second copy will

be sent. Awake Time will continue in its entirety for any normal protocol requests.

4 Acknowledge Sensor will send a single Acknowledge message indicating that it is awake. Coordinator now can

send messages during the awake period.

5 Auto Send 5 Sensor will first acquire range and other status information followed by sending a single Command

1 message containing up to 8 blocks of recorded Event Data. The Awake Time will continue in its

entirety for any normal protocol requests. There is no demand for any acknowledgement and no

retry will be sent. The Data Collection Interval Register is disabled. (FW ver 26 or greater)

6 Auto Send 6 Sensor will first acquire range and other status information followed by sending a single Command

1 message containing up to 8 blocks of recorded Event Data. Sensor will wait for ½ the

programmed Awake Time then send a second copy. The Awake Time will continue in its entirety

for any normal protocol requests. There is no demand for any acknowledgement and no retry will

be sent. The Data Collection Interval Register is disabled. (FW ver 26 or greater)

This is the Acknowledge Message sent by Coordinator after it has received Event Data and Configuration Register 8 set to 3.

Sensor ID Host ID 6 200 1 checksum

default=1 default=251 Acknowledge read history buffer

This is the Acknowledge Message sent by Sensor after sensor wakes up and Configuration Register 8 set to 4.

Host ID Sensor ID 6 200 0 checksum

default=251 default=1 Acknowledge
