10164-L Sampler Control Cable for use with Isco and Sigma Autosamplers
TABLE 4-4. Wiring for Example of Inhibiting a
Sigma Sampler Onboard Program
Color Description CR800, CR850, CR1000, or CR3000
Purple Ground
Brown Control Port C1
Clear Shield
For samplers such as the products manufactured by Sigma, the onboard
program is inhibited by setting the control port high.
For example, if the cable is wired as shown in TABLE 4-4, a datalogger
program that includes the following CRBasic instruction will inhibit a Sigma
sampler’s onboard program:
PortSet(1,1)
Above is only a portion of the CRBasic program.
After a Sigma sampler’s program has been inhibited, it can be allowed to run
by setting the port low.

Wire Color CR10(X)
Purple G
Yellow C2
Red 12V
Clear G
To trigger the sampler, pulse port 2 using a set of instructions such as follows:
Do (P86)
1: 42
Set Port 2 High
; Note: The 50 in the third parameter keeps the
; port high for 0.5 seconds. Some users have
; reported using a delay of 1 sec (100 in
; parameter 3) to ensure reliable triggering of
; the sampler.
