Initial Setup Guide
A few quick comments first. The AccuBubble utilizes the SDI-12 command syntax. This means
that all commands are case sensitive and are immediately responded to if recognized. If they are not
recognized, there is no response. The first character of every command is the address of the unit.
By default this is 0 (zero). However, if the address is set to any alpha/numeric value other than 0,
then that alpha/numeric value must be used. The first character of every response is also the
address character. If the command is one which requires time to process, i.e., taking a
measurement, then the AccuBubble responds immediately with the time required perform the
measurement and with the number of values to be returned. For example, in response to a 0XPC!
Command, the AccuBubble (at address 0) will respond with 02553. The first character is the
address, the next three are the number of seconds until the measurement is ready, 255, and the last
character is the number of parameters that will be returned, 3. At this point the user should wait the
255 seconds before entering the 0D0! Command. If the AccuBubble finishes the command in less
than 255 seconds, it will output a service request, which just consists of its address, 0. Once the
service request is received, the user can request the data with the 0D0! Command.
1.
Steps 2-11 must be completed with each initial installation and anytime the orifice line has been
removed from the AccuBubble. (Though not required, it is a good practice to check the
commands to insure your specific setup is correct.)
2.
With the orifice line attached to the AccuBubble and deployed in the water, enter the command
0XPR+60+30! (the ! is not needed if entering commands from the front panel of an 8200/8210
or 8400). This will purge the line for 60 seconds, and then wait 30 seconds before returning a
value. This is done to clear the line of any water and refuge after initial orifice line installation,
or after the orifice line has been open at the AccuBubble.
3.
With the orifice line in water, enter the command 0XPC! (the ! is not needed if entering
commands from the front panel). The unit will respond with 02553. Where 0 is the address, 255
is time in seconds before value is returned and 3 is how many values will be returned.
4.
The pump sequence is a long run of 10 or more seconds, a long wait, a short pump run of
pump_on length (factory default of 0.1 second), a wait, and then 0.1 second run of the pump.
At this point the command is finished and the unit will respond with a 0. The 0 will not be
displayed if using the 8200/8210 Inspect System/Enter SDI Commands. The total time required
for this characterization is dependent upon orifice line length. It may not take the 4 ¼ minutes
requested. After you see the 0, type 0D0!. If this command is used in the 8200/8210 Inspect
System/Enter SDI Command, you must wait for 4 ¼ minutes or the three pump runs to issue
the 0D0! Command. The unit will respond with some thing like 0+10+25+8.2, where 10 is the
purge on time, 25 is the purge off time, and 8.2 is the pump off time used for averaging.
IMPORTANT NOTE FOR -1 BUBBLERS: WHATEVER THE RETURNED VALUE IS IN
STEP 3 (0XPC! Command), 0D0!, WRITE IT DOWN AND ENTER IT INTO THE
ACCUBUBBLE IN STEP 5! For -3 and -4 Bubblers, if any of the numbers returned are
negative, then the characterization is questionable and should be repeated (go back to step 3).
5.
Note: This step is only required for 5600-0131-1 units running software prior to version
V2.0.
Enter the command 0XPT+10+25! (the ! is not needed if entering commands from the front
panel of an 8200/8210 or 8400). The unit will respond with 00015. Enter the command 0D0!.
You should see the values you just entered. Now the timing parameters are set.
6.
To set the User Units of Pressure, enter 0XUP+0+2! (This will set the bubbler up to respond in
Feet of water with 2 right digits). If meters of water with mm resolution is desired, the
Command should be 0XUP+4+3!
