Response:

atX,Use chksum GoeIU~<cr><lf>

Example of the other data query commands with CRC (when the

device address is 0):

In every case the response contains a three-character CRC before the

<cr><lf>.

For selecting the parameters to be included in the response messages,

changing the units and making other configurations of the measured

parameters, see Chapter 8, Sensor and Data Message Settings, on page

95.

Automatic Mode

When automatic ASCII protocol is selected the sensor sends data

messages at user configurable update intervals. The message structure

is same as with data query commands aR1 and aR5. You can choose an

individual update interval for each sensor, see Chapter 8, Sensor and

Data Message Settings, on page 95, sections Changing the Settings.

Example:

0R1,Dm=027D,Sm=0.1M<cr><lf>

0R5,Th=76.1F,Vh=11.5N,Vs=11.5V,Vr=3.510V<cr><lf>

where

a = Device address

tX,Use

chksum

= Text prompt

Goe = Correct three-character CRC for the ar1 command

IU~ = Three-character CRC for the response message

<cr><lf> = Response terminator

Supervisor query = 0r5Kcd<cr><lf>

Combined message query = 0rBVT<cr><lf>

Composite data message query = 0r0Kld<cr><lf>
