CAUTION WHEN CHANGING JUMPERS.
Even if a unit has been factory calibrated, it is a good
idea to perform this calibration as a simple bench
check. The procedures provide a safe means of
uncovering any unit damage that may have occurred
during shipping, and offer a familiarization with TIY
operation in the safety of a testing environment,
separate from the intended process or application.
These procedures should be carried out in an envi-
ronment considered appropriate for general testing of
electronic equipment, rather than in the field. Use a
technician’s bench or a similar, lab-type environment.
Setting the Configuration Jumpers
Solderless jumpers are used to configure the TIY’s
user-selectable operating features.
Figure 1 shows the layout of the configuration jump-
ers. The layout of the jumpers in the HP- and DIN-
style units are identical.
The jumpers for HP-style units are accessed through
a removable panel in the rear of the unit. A narrow,
slotted-head screwdriver may be used to gently pry
the panel off the unit.
Jumpers for DIN-style units are accessed by remov-
ing the small, L-shaped panel from the upper right-
side of the unit. This panel folds over the top of the
unit and is secured with a single screw on top.
A label is affixed on the outside of each unit, below
the jumper array, that identifies each jumper (e.g.,
J301, J302, J303, etc.).
Setting (or installing) a jumper means shorting two
adjacent pins together. (Jumpers are provided with
each unit.) Figure 1 shows how a jumper is installed
and how one is stored when unused.
Table 3 lists the jumper options for configuration
jumpers J301 through J305. The remaining jumpers
are listed in Table 4. Subsequent paragraphs contain
descriptions of the jumpers.
