Configuring and Operating the BioBlock on the LISST-100X
The LISST-100X comes pre-configured for use with the BioBlock. There is a dedicated 3-
pin BioBlock connector on the endcap and the firmware is designed to utilize the BioBlock
shutter during sampling. The only thing remaining is to inform the firmware that the BioBlock
has been installed. To do this a simple two letter command has been added to tell the
instrument the BioBlock is attached. The command is BB (short for BioBlock). The
summary of the command is below.
BB BioBlock Configuration and Test Command
Syntax: BB or bb
Description: Configure the BioBlock Connection Setting and send test commands.
Example: input: BB 1
output: BioBlock is now connected!
Input options:
0 = BioBlock is not connected.
1 = BioBlock is connected.
10 = BioBlock is connected and issues a command to close the
BioBlock.
11 = BioBlock is connected and issues a command to open the
BioBlock.
As shown in the shown in the table above the BB command has multiple input options. In
addition to telling the firmware that the BioBlock is connected, the command can also be
used for testing the operation of the BioBlock. For example, issuing a BB 10 command will
enable the connection and send the command to close the BioBlock. A BB 11 command
will also enable the connection and send an open command.
During normal sampling the BioBlock will be commanded to open before each sample is
collected. After the sample is recorded the time until the next sample is computed. If the
time remaining is less than 30 seconds the BioBlock will remain open. If the time is greater
than 30 seconds the BioBlock will close and then reopen two seconds before the next
sample.
When using the Real Time mode of the LISST-SOP software, the BioBlock will not be
commanded to open at the beginning of sampling. Therefore it must be manually opened
using the BB 11 command.
To issue the BB command, open the Terminal window on the standard LISST-SOP
Windows software. At the L100X:>> prompt type BB followed by the input option. Pressing
Enter will set the BioBlock connection and issue any open or close commands. If a Display
Status (DS) command is now issued the listing of the instrument status will now include a
message that the BioBlock is now connected.
The BioBlock uses two standard alkaline D batteries for power. The electronics inside the
BioBlock includes a battery monitor. If the voltage of the battery is too low a signal will be
sent to the LISST-100X. If LISST-100X sees that the BioBlock battery is low it will
