10164-L Sampler Control Cable for use with Isco and Sigma Autosamplers
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

To sense sampler events, use Instruction 3 with a configuration code of 0.
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.
4.2.2.2 CR10(X) Control Port Interrupt Method
For the CR10(X), 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(X). Each time the sampler reports an event, the CR10(X)
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.
