If you find a weak wireless communication (where the signal
strength indicates “Bad”), we suggest you install the W321/341
computers at some other place within a stronger wireless signal
range, or boost the signal by installing another wireless access
point or bridge.

Installing the W321/341
Wall or Cabinet Mounting
The W321 have built-in “ears” for attaching the embedded
computers to a wall or the inside of a cabinet. We suggest using
two screws per ear to attach the W321/341 to a
wall or cabinet.
The heads of the screws should be less than 6.0
mm in diameter, and the shafts should be less
than 3.5 mm in diameter, as shown by the figure
at the right.
The W341 comes with two metal attachment plates for attaching
the embedded computer to a wall or the inside of a cabinet. First,
use two screws per bracket to attach the brackets to the rear of the
W341. Next, use two screws per bracket to attach the W341 to a
wall or cabinet.
DIN Rail Mounting
DIN rail attachments can be purchased separately to attach the
product to a DIN rail. When snapping the clips onto the DIN rail,
make sure that the stiff metal springs are at the top.
