19. Glossary
- RSSI
Received Signal Strength Indicator - Is a indicator of the strength of a RF signal. RSSI can be in any number of units. In Level Up we only referer to signal strength in dBm.
- EMS
Electrical Mangement System - typically used to protect electrical appliances and other sensitive electrical equipment from power surges either by lightning strikes or other power surges on the electrical grid.
- RTC
Real Time Clock - a integrated circuit that specifically is used to track time. These devices are highly accurate and typically have battery backup options that allow them to keep time for long periods with very little power consumption.
- BLE
Bluetooth Low Energy - Bluetooth Low Energy (Bluetooth LE, colloquially BLE, formerly marketed as Bluetooth Smart[1]) is a wireless personal area network technology designed and marketed by the Bluetooth Special Interest Group (Bluetooth SIG)[2] aimed at novel applications in the healthcare, fitness, beacons,[3] security, and home entertainment industries.[4] It is independent of classic Bluetooth[clarification needed] and has no compatibility, but BR/EDR and LE can coexist. The original specification was developed by Nokia in 2006 under the name Wibree,[5] which was integrated into Bluetooth 4.0 in December 2009 as Bluetooth Low Energy.
- CHG
Charge Indicator - This LED when on indicates that the Level Up module is charging the internal battery.
- ESD
Electrostatic Discharge - Electrostatic discharge (ESD) is the sudden flow of electricity between two electrically charged objects caused by contact, an electrical short or dielectric breakdown. A buildup of static electricity can be caused by tribocharging or by electrostatic induction. The ESD occurs when differently-charged objects are brought close together or when the dielectric between them breaks down, often creating a visible spark.
- MAC
Media Access Control Address - is a unique identifier assigned to a network interface controller (NIC) for use as a network address in communications within a network segment. This use is common in most IEEE 802 networking technologies, including Ethernet, Wi-Fi, and Bluetooth. Within the Open Systems Interconnection (OSI) network model, MAC addresses are used in the medium access control protocol sublayer of the data link layer. As typically represented, MAC addresses are recognizable as six groups of two hexadecimal digits, separated by hyphens, colons, or without a separator.
- SHORE
Shore Power - The Shore LED indicates that the Level Up module has detected the RV is connected to the power pedistal and AC power has been detected. This does not necessarily indicate that power has been passed through into the RV by the Progressive Industries EMS.
- AC_ON
AC ON - Ths AC_ON LED indicates when SHORE power has been detected and the Progressive Industries EMS has allowed power to pass through to the RV converter. This means that all your AC appliances and plugs are hot.
- F2B
Front to Back - This is an Level Up term to reference the front to back measurement. On a tow behind trailer this would be the distance between the axle and the tongue jack. On a fifth wheel trailer this would be the distance between the axle and the front jacks.
- S2S
Side to Side - This is an Level Up term to reference the side to side measurement. On a trailer regardless of type or motorized RV this is the outside distance as measured from the driverside axle to the passenger side axle.
- dBm
decibels Relative to a mW - is a unit of level used to indicate that a power level is expressed in decibels (dB) with reference to one milliwatt (mW). It is used in radio, microwave and fiber-optical communication networks as a convenient measure of absolute power because of its capability to express both very large and very small values in a short form. dBW is a similar unit, referenced to one watt (1000 mW).
- mW
milli Watt - The milliwatt (mW) is equal to one thousandth (10−3) of a watt. A typical laser pointer outputs about 5 milliwatts of light power, whereas a typical hearing aid uses less than 1 milliwatt.[15] Audio signals and other electronic signal levels are often measured in dBm, referenced to 1 milliwatt.
- Magnitude
Magnitude -
- Pitch
Pitch - Is the front to back up and down movement of the RV.
- Roll
Roll - is the side to side up and down movement of the RV.
- Yaw
Yaw - is only used in the Level Up module to calibrate out any inaccuracies associated with the physical installation of the model.
- L1
L1 or Live 1 is the HOT terminal. If your RV is equipped with a 30 AMP circuit the connector will have three terminals. Hot (L1), Neutral and Ground. The voltage between L1 and Neutral will be 120 VAC (±5%) in North America. The wire color is black. 1 Reference https://usa.p3connectors.com/electrical-wiring-colors/
- L2
L2 or Live 2 is the other HOT terminal. If your RV is equipped with a 50 AMP circuit the connector will have four terminals. L1 (Hot), L2 (Hot), Neutral and Ground. The voltage between L2 and Neutral will be 120 VAC (±5%) in North America. The wire color is red 1. Reference https://usa.p3connectors.com/electrical-wiring-colors/
- Ground
Ground - Ground or earth in a mains (AC power) electrical wiring system is a conductor that provides a low-impedance path to the earth to prevent hazardous voltages from appearing on equipment (high voltage spikes). The terms ground and earth are used synonymously; ground is more common in North American English, and earth is more common in British English. Under normal conditions, a grounding conductor does not carry current. The wire color is green.
- Neutral
Neutral - Neutral is a circuit conductor that normally completes the circuit back to the source. Neutral is usually connected to ground (earth) at the main electrical panel, street drop, or meter, and also at the final step-down transformer of the supply. The wire color is white.
- RMS
Root Mean Square - In mathematics and its applications, the root mean square (RMS or rms or rms) is defined as the square root of the mean square (the arithmetic mean of the squares of a set of numbers).
- FCC
Federal Communications Comission - The Federal Communications Commission (FCC) is an independent agency of the United States federal government that regulates communications by radio, television, wire, satellite, and cable across the United States. The FCC maintains jurisdiction over the areas of broadband access, fair competition, radio frequency use, media responsibility, public safety, and homeland security.
- IC
Industry Canada - Is the Canadian federal organization mandated to increase global trade, scientific research, and setting telecommunications policies.
- FT4
FT4 Cable Rating - Cable rating for use in risers and environments where the cable is not run inside a air handling plenum.
- FT6
FT6 Cable Rating - Cable ratings for any cable run inside a plenum air space.
