POLL — Poll Data

This command fetches data from WMT700. You need to specify
the data message number in the polling command.

NOTE

When WMT700 is in the low-power mode, it does not receive the first
character in the command. Thus, you must send an extra character
(space) before the polling command to receive data.

$aPOLL,y<CR><LF>

Where

$

=

Fixed text

a

=

WMT700 address. If the value is 0, it refers to any
WMT700 address

y

=

Identification number for the data message format.
For a list of data message formats, see Table 40 on page
128

Example:

In this example WMT700 custom data message 1 is polled from
WMT700.

$0POLL,1<CR><LF>

SLEEP — Enter Low-Power Mode

This command switches WMT700 from the normal operating
mode to the low-power mode. WMT700 will resume normal
operation after sleep period determined by the sleepTime
parameter has elapsed, or when a character is received on data
port COM2. For more information on the sleepTime parameter,
see Appendix D, Configuration Parameters, on page 205.
