10164-L Sampler Control Cable for use with Isco and Sigma Autosamplers
1. General
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. Each of these functions is independent of the others and may be
combined as desired.
2. Specifications
Sampler Connection: mil-spec, 6-pin circular connector (shell size 14)
Datalogger Connection: pigtail with individual conductors
Current Drain: < 1 mA; consult the specifications of the connected
sampler to determine its power considerations.
Cable Length: 50 ft standard; 1000 ft maximum (see Cable Length
Considerations)
2.1 Cable Length Considerations
In most applications, the 10164 cable connects the datalogger to a sampler
residing in the same instrumentation shack. Therefore, a cable length of 50 ft
or less is typically used.
Cable lengths up to 1000 ft are possible if the sampler supports long event
markers. For example, the Isco-brand sampler has a 3 second event marker,
which is an adequate duration for a 1000 ft cable length.
CAUTION
The 10164 does not include surge protection. Therefore,
longer cables need to be protected from surges in order to
safeguard the system from electrical transients. A
recommended method of doing this is to place the cable in
a metal conduit and then bury the conduit at a depth of at
least one foot.

3.1 General Wiring Information
Figure 3-1 shows a schematic of the 10164 and Table 3-1 shows pin connector
and wire functions.
Sections 3.2 through 3.4 provide information about connecting the wires to a
datalogger. The datalogger wiring depends on the function.

3.4 Inhibit Sampler’s Program
Some samplers run their own program that you might want to inhibit. The
wiring for inhibiting the sampler’s onboard program depends on the program’s
logic. Table 3-4 shows the wiring for Sigma samplers that require a control
port to be set high to inhibit their onboard program. Table 3-5 shows the
wiring for Isco samplers that require a control port to be set low to inhibit their
onboard program.

4. Programming
Insulate and tuck the unused wires out of the way.
The datalogger is programmed using either CRBasic or Edlog. Dataloggers
that use CRBasic include the CR800, CR850, CR1000, and CR3000.
Dataloggers that use Edlog include the CR10(X), CR510, CR500, CR23X, and
21X.
With this cable, the datalogger can be programmed to:
• Trigger the sampler
• Sense and record when the sampler has taken a sample
• Inhibit the sampler from running its onboard sampling routine
Each of these functions is independent of the others and may be combined as
desired.

4.1 CRBasic Programming
4.1.1 Trigger Sampler
To trigger the sampler, the datalogger program must set the port high, delay for
at least 0.5 seconds, and then set the port low.

For example, if control port 2 is used (see Table 4-1), a datalogger program
that includes the following CRBasic instructions will trigger the sampler:

PortSet (2,1)
Delay (0,50,mSec)
PortSet (2,0)
NOTE
Above is only a portion of the CRBasic program.
4.1.2 Sense Sampler Event
To sense the sampler event, use the PulseCount instruction with the PConfig
parameter set to high frequency (code 0). The value stored in the variable
should be totalized.
The following example program will sense the sampler events when the cable
is wired to pulse channel 1 (see Table 4-2).

4.1.3 Inhibit Sampler’s Program
To inhibit a sampler’s onboard program, use the PortSet instruction. Whether
the port should be set low or high depends on the onboard program’s logic.
For samplers such as the products manufactured by Isco, the onboard program
is inhibited by setting the control port low.

For example, if the cable is wired as shown in Table 4-3, a datalogger program
that includes the following CRBasic instruction will inhibit an Isco sampler’s
onboard program:
PortSet (1,0)

After an Isco sampler’s program has been inhibited, it can be allowed to run by
setting the port high.

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)
NOTE

After a Sigma sampler’s program has been inhibited, it can be allowed to run

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.

4: 0 mV Excitation

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)

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.

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
Do (P86)
1: 51 Set Port 1 low ; (41 would set it high)
The logic for Sigma samplers is just the opposite. A high signal
inhibits the sampler.
