STEP-BY-STEP EXAMPLES (For a single PPT2 connection, default 00 address)
READ A SINGLE PRESSURE
Once the PPT2 is powered up and connected to a computer, enter the following command: (do not type "<cr>",
press the ENTER/RETURN key)
User Types on the keyboard:
*00P1 <cr>
PPT2 Response:
?00CP=14.4582
Where
*
00
P1
Note: The "?" indicates the response from a null addressed PPT2– one which has not been assigned a device ID.
A null address, 00, is coded into each PPT2 at the factory. Refer to the ID command in Section 5 for a description
of addresses and responses.
The "CP=14.4582" indicates a compensated pressure of 14.4582 psi. (Your unit may not show this specific
reading, depending on the applied pressure it is measuring.)
SET DEVICE ID
To give the PPT2 an assigned address of 01 up to 89, enter the following commands:
*00WE<cr>
*00ID=01<cr> This sets the null addressed PPT2 to device ID=01.
Note: The new device ID is now used in subsequent commands
*01S=<cr>
Response: #01S=00052036
The "#" now replaces the "?" in the header and indicates the PPT2 response is from an address-
assigned unit.
