Using the XLP 6000 Command Set
K<n>
Backlash Increments
The [K] command sets the number of backlash increments. The syntax for
this command is:
[K<n>]
where <n> = 0..31 in full step mode (12 is the default),
and <n> = 0..248 in fine positioning mode (96 is the default).
When the syringe drive motor reverses direction, the carriage will not move
until the backlash due to mechanical play within the system is compensated.
To provide this compensation, during aspiration, the plunger moves down
additional increments, then backs up the set number of backlash increments.
This ensures that the plunger is in the correct position to begin a dispense
move. Note that a small volume of fluid flows out the "input" side of the valve
during this operation.

Set User Data Command
The [>] command loads a byte of user data into non-volatile memory:
[> <n1>, <n2>], where: <n1> is 0..15 (location in non-volatile memory) and
<n2> is 0..255 (data to load into non-volatile memory).
U<n>
Write Pump Configuration to Non-Volatile Memory
The [U] command is used to write configuration information to the non-volatile
memory. The pumps are configured during the manufacturing process but
can be reconfigured at any time with the following [U] commands:
