• Mounting the P/N 899389-000 cable 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 P/N 899389-000 cable 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 external P/N 454173-000 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 P/N 899389-000 cable. Also, the touchscreen cable must be
connected to the P/N 899389-000 cable as the back case is being reinstalled,
and the ground cable from the transient protection must also be connected.
The shell of the DB9 connector is internally connected to the ground wire.
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).
P/N 454173-000 is a shielded, 9-pin, straight-through extension cable. Other
common computer data cables may be substituted. Contact Elo if special
requirements exist that cannot be satisfied with a standard cable
configuration.
