Example Program String
M <n>
Delay Command Execution
The [M] command delays execution of a command in milliseconds to the
closest multiple of five. This command is typically used to allow time for liquid
in the syringe and tubing to stop oscillating, thereby enhancing precision. The
syntax for this command is:
[M<n>]
where <n> = 0..30,000 milliseconds (5 is the default)
H <n>
Halt Command Execution
The [H] command is used within a program string to halt execution of the
string. To resume execution, an [R] command or TTL signal must be sent.
The syntax for this command is:
[H<n>]
where <n> = 0..2
Two TTL inputs are available, input 1 (J5 pin 7) and input 2 (J5 pin 8). They
control execution as follows:
