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).
