Mount the USB I/O assembly (PN 250103) at the back of the display. The
USB I/O assembly connector shell must be grounded to satisfy safety agency
approvals, as the grounding protects the user in case a wiring fault develops
in the display. Attach the ground wire supplied in the kit to one of the USB I/
O assembly’s mounting screws and the other end to chassis ground if the
shell is not already grounded.
Note:
The USB I/O assembly will fit the same size cutout as a DB9 connector.
Mechanically, there may be several options for mounting the bulkhead
connector on the display case:
•
Mounting the assembly to a chassis member that is exposed to the display
exterior. This requires a DB9 hole punch to mount the connector neatly,
but makes reassembly of the back of the case very easy, and is usually the
best functional and cosmetic solution.
•
Mounting the assembly to a concealed chassis member, with a hole in the
exterior of the case (usually plastic) to provide access to the connector.
This technique also requires a metal punch to mount the DB9 connector,
but the plastic case hole can often be routed, nibbled, or punched with
simple tools, and usually provides a neat appearance. This is also an
excellent functional solution as the back case is again very simple to
reassemble.
•
Mounting the assembly to the plastic case. Plastic cases are usually rather
thick, making it necessary to mount the flange of the connector on the
outside of the case. This is cosmetically less acceptable than an inside
mount and there is less support for the serial cable. Also the standard DB9
hole may not provide adequate clearance for the connector. Avoid
mounting to curved surfaces if possible as hole punching is more difficult
and mounting hardware will warp the connector when tightened. If
mounted on the inside, the mounting hardware may interfere with proper
mating with the 18-inch USB cable (P/N 793054-000).

Connect one end of the 18-inch USB cable to connector P2 on the controller
and the other end to the internal connector on the USB I/O assembly.
An escutcheon, or identifying metal plate labeled with the legend "Touch
Interface" (P/N 172001) is included in the touchscreen installation kit
(P/N 458095-000). It provides an attractive and convenient finish to most of the
bulkhead mounts typically used on a display. A similar plate is also available
with vertical labeling (P/N 172003).
