4.3 Command Syntax
A sequence of single letter command, preceded by a space, controls the transducer. Some
commands require one or more numeric values to follow the command letter. The correct
number of parameters must be sent for this particular command. A comma separates all
command fields. The transducer accepts upper-case or lower-case letters.
4.3.1 Direct Mode Syntax
Direct mode commands are in the form:
Command:
<SPACE><Command>,<P1>,<P2>,…,<Pn><CR>
The following example selects the output update of one reading every 3 seconds:
Command:
<SPACE>A,3<CR>
4.3.2 Addressed Mode Syntax
In this mode an address field must be added to the start of the general format as follows:
Command:
<SPACE><Address>:<Command>,<P1>,<P2>,…,<Pn><CR>
The following example gets the device at address 1 to transmit pressure:
Command:
<SPACE>1:R<CR>
4.4 Measurement Commands
4.4.1 R - Get Reading
This command polls the devices in the network for a reading. Although used mainly in the
addressed mode it can also be used in direct mode.
