KDC-210 – Initial Setup
This section provides initial setup instructions.
Preinstallation Considerations
Mounting
A wide variety of LCD and bump bar mounting options are available. Contact your
Oracle MICROS representative for more information.
KDC-210
The KDC-210 requires Cat 5e or Cat 6 patch cable connectivity near each location.
Wired Bump Bar
The MICROS Wired Bump Bar is supplied with a 6ft. (1.8M) or 15ft (4.5M) cable.
Wireless Bump Bar
Before installing the mounting brackets, consider the following site-related issues to
ensure the best possible functionality from the MICROS Wireless Bump Bar in an
active RF environment:
•
Range: Distances up to 30 feet are possible when the dongle and bump bar are
within sight of each other, with no obstructions in the path of the RF signals. As the
number and type of obstructions between the dongle and bump bar increase, the
range decreases.
•
Classification of RF Obstructions: RF signals encounter two types of
obstructions that either weaken or reflect the signal, depending on its material
composition. The first type of obstruction is one that allows the signal to pass
through, but attenuates, or weakens it. Some examples include walls constructed
of wood, drywall, people, and concrete block. The amount of attenuation is
proportional to the total thickness of materials that the RF signal must penetrate
when traveling the line-of-sight path. The second type of obstruction is one that
reflects the RF signals, allowing little or none to pass through. The reflected RF
energy can cause interference even when the dongle and bump bar are located
within line-of-sight. Any type of metallic substance falls into this category. This
includes objects such as stainless steel food preparation areas, walk-in freezers,
steel doors, and steel support beams.
•
Local RF Interference: The RF signals emitted by the MWBB are located in the
unlicensed 2.40 - 2.50 GHz ISM band. Nearby occupants of this band include
microwave ovens (2.485 GHz), 802.11 b/g Wi-Fi, cordless phones, IEEE 802.15.4
(WPAN), ZigBee, and other personal area networks. Ensure the MWBB is located
as far from these devices as possible. The greater the distance between the
dongle and the bumpbar, plus the greater the number of obstructions between the
two devices, allows extraneous RF devices to impact the operation of the wireless
bump bar. In cases where the site is too noisy in terms of RF interference, Oracle
MICROS recommends the use of the MBB-10 and MBB-20 wired bump bars.
