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.

4.2.1 Trigger Sampler

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.

Excitation with Delay (P22)

1: 1 Ex Channel

2: 0 Delay W/Ex (units = 0.01 sec)

3: 50 Delay After Ex (units = 0.01 sec)

4: 0 mV Excitation

Do (P86)

1: 52 Set Port 2 Low
