Using Switches to Set the Address
NOTE:
It is usually easier to set the address via a software command, as described in the next section.
Remove the cover for the sensor and set the switches to one of the settings as follows:
Address
Switch 4
Switch 3
Switch 2
Switch 1
0

Note: all other switches in the ACCUBAR
®
need to be OFF. The factory default for all switches is OFF
(address 0). The ACCUBAR
®
will not operate properly if any of the switches (5 to 8) are set ON.
Using a command to Set the Address
In order to set the address by SDI-12 command or RS-232 command, the DIP switch address must be set to
0 (Switches 1,2,3,4 OFF). This is the factory setting for the switches. Also, no other SDI-12 devices
connected to the system should be set to address 0 or to the desired ACCUBAR
®
address. Hint: if you do
not know the address of a particular ACCUBAR
®
, use the unknown address command to have the
ACCUBAR
®
identify itself.
NOTE: There can only be one ACCUBAR
®
connected in order for the unknown address command to
work. The syntax for the unknown address command is
*X?!
The ACCUBAR
®
also supports an alternate version of the unknown address command which is a command
acknowledge to a wildcard address. The syntax for this version is:
*!
Beginning with version 1.2 of the SDI-12 specification there is an address query command defined.
Therefore another version of the request unknown address or address query command is:
?!
The SDI-12 command for setting the ACCUBAR
®
's address is the XAD command
