i.
A comma separates all command fields.
ii. The transducer accepts upper-case or lower-case letters.
iii. Numeric values must be entered using a decimal point, not a decimal comma, to separate
the integer and fractional components.
iv. Characters to separate numeric values into tens or thousands must not be used.
6.3.1 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>
6.3.2 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>
6.4 Measurement Commands
6.4.1 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.
Command:
<SPACE>R<CR>
Reply:
<Pressure value><Pressure units><CR>
Result:
A new pressure reading is transmitted.
Command:
<SPACE>*R<CR>
Reply:
<Pressure value><Pressure units><CR>
Result:
A new pressure reading and the units of pressure measurement are
transmitted.
