Back Cover Variants
Omnii has three standard variants for the back cover module.
•
Expansion Back Cover - a slim back cover with separate end-cap, and a back plate that can be
removed for an optional pod expansion module (see Section 3.2.4: "Scanner/Imager Vari-
ants"). This back cover can also have an optional built-in speaker and/or camera, which need
to be considered when designing modules.
•
Large Standard Back Cover - a single-piece back cover module that also covers the end-cap
area and accommodates an integrated scanner or imager (see Section 3.2.4: "Scanner/Imager
Variants").
•
Auto-Range Standard Back Cover - similar to the Large Standard Back Cover but with
different options for the integrated scanner or imager (see Section 3.2.4: "Scanner/Imager
Variants").
3.2.4
Scanner/Imager Variants
Omnii comes standard with no scanner or imager installed. A scanner or imager engine can be in-
stalled in a pod expansion module and mounted to the expansion back cover. Alternatively, a
scanner or imager could be mounted in the end-cap of the unit, with an appropriately designed
end-cap. The scanner or imager engine attaches to an expansion port on the Omnii main logic
board through a flex cable.
Only one internal bar code scanner or imager can be installed in Omnii at a time. The internal
scanner or imager can be activated from the trigger switch on the Omnii pistol grip (if present),
from the [SCAN] buttons on the Omnii keyboard and side panels, or from another software-
assigned key on the keyboard.
The following scanner/imager options are currently available to order from the factory:
