10164-L Sampler Control Cable for use with Isco and Sigma Autosamplers

4.1 CRBasic Programming

4.1.1 Trigger Sampler

To trigger the sampler, the datalogger program must set the port high, delay for

at least 0.5 seconds, and then set the port low.

TABLE 4-1. Wiring for CRBasic

Triggering Sampler Example

Color Description CR800, CR850, CR1000, or CR3000

Purple Ground

Yellow Control Port C2

Red Power 12V

Clear Shield

For example, if control port 2 is used (see TABLE 4-1), a datalogger program

that includes the following CRBasic instructions will trigger the sampler:

PortSet(2,1)

Delay(0,50,mSec)

PortSet(2,0)

Above is only a portion of the CRBasic program.

4.1.2 Sense Sampler Event

To sense the sampler event, use the PulseCount() instruction with the PConfig

parameter set to high frequency (code 0). The value stored in the variable

should be totalized.

The following example program will sense the sampler events when the cable

is wired to pulse channel 1 (see TABLE 4-2).
