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.
