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.
Trigger Sampler
Wire color CR10 21X BDR320
purple G Ground GND yellow C2 Control 2 C2 red 12V +12 12V clear G Ground GND
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
Sense Sampler Event Markers
Pulse port method:
Wire color CR10 21X BDR320
purple G Ground GND orange P1 Pulse 1 P1 clear G Ground GND
To sense sampler events, use Instruction 3 with a configuration code of 0 (no configuration code or Reps are required for the BDR320):
Pulse (P3)
1: 1 Reps 2: 1 Pulse Input Chan 3: 0 High frequency
(configuration code) 4: 2 Loc [:EVENTS] 5: 1 Mult 6: 0 Offset
To record the events in the datalogger's final storage area, remember to totalize the events temporarily stored in Input Location 2 in this example.
Do (P86)
1: 52 Set Port 2 Low
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:
Excitation with Delay (P22)
1: 3 EX Chan (or the channel
you select) 2: 50 Delay w/EX (units=0.01sec) 3: 0 Delay after EX (units=0.01sec) 4: 2500 mV Excitation
CR10 control port interrupt method:
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.

Inhibit Sampler’s Program
Wire color CR10 21X BDR320
purple G Ground GND (Isco) green C1 Control 1 C1 (Sigma) brown C1 Control 1 C1 clear G Ground GND
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:
Do (P86)
1: 51 Set Port 1 low ;(41 would
set it high)
