4.1.3 Inhibit Sampler’s Program
To inhibit a sampler’s onboard program, use the PortSet() instruction.
Whether the port should be set low or high depends on the onboard program’s
logic. For samplers such as the products manufactured by Isco, the onboard
program is inhibited by setting the control port low.

Isco Onboard Program

For example, if the cable is wired as shown in TABLE 4-3, a datalogger
program that includes the following CRBasic instruction will inhibit an Isco
sampler’s onboard program:
PortSet(1,0)
Above is only a portion of the CRBasic program.
After an Isco sampler’s program has been inhibited, it can be allowed to run by
setting the port high.
