CSI MODEL 10164-L SAMPLER CONTROL CABLE
FOR USE WITH ISCO AND SIGMA AUTOSAMPLERS
The 10164-L sampler control cable enables a datalogger to trigger an Isco, American Sigma, or
connector-compatible autosampler. Through this cable, the datalogger can inhibit the sampler from
running its programmed sampling routine and sense and record when the sampler indicates that it has
taken a sample. The following examples illustrate its use. Each of these functions are independent of
the others and you may combine functions as desired. You should insulate and tuck out of the way any
unused wires.

To trigger the sampler, pulse port 2 using a set
of instructions such as follows:
To sense sampler events, use Instruction 3 with
a configuration code of 0 (no configuration code
or Reps are required for the BDR320):

Set Port 2 High
Pulse (P3)
; 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.

Set Port 2 Low
For the CR10, there is another useful method for
sensing and recording sampler events. This
method uses the control port 8/subroutine 98
interrupt feature of the CR10. Each time the
sampler reports an event, the CR10 records the
sample number with a time stamp in final storage.
In this example, sampler events will show up as
output arrays with an array ID of 400.
For the CR10 and the 21X, you can also supply
the trigger signal from switched excitation if no
control ports are available. In this case,
connect the yellow cable to the desired
excitation channel (say E3) and pulse the
channel using Instruction 22 as follows:

To inhibit an Isco sampler from running its own
program, set control port 1 low using a program
control instruction such as Instruction 86. To
allow the sampler to run its program, set it high.
NOTE: The logic for Sigma samplers is just
the opposite. A high signal inhibits the
sampler.
Example for inhibiting an Isco sampler's
program:
