3.2 CONFIGURATION STRAPS
In addition to the configuration switches described above, the
Model 2003 also has two internal straps: One that set the RS-232 or
RS-485 Operation; and, one that determines whether the keyboard
connection passes through the 2003, or connects between devices in
parallel. In order to configure these straps, you must open the Model
2003 case.
NOTE: Before opening the case, determine whether the default
settings are correct for your application (see Sections 3.2.3 and
3.2.4)
3.2.1 Opening the Case
To open the Model 2003 insert a large flat head screwdriver into
an open slot on either side of the case, as in Figure 5.
Twist the screwdriver head slightly and the top half of the case will
separate from the lower half, as in Figure 6, below.
To close the case, fit the 2 halves together snugly and snap them
back in place.
