Glossary of TermsGlossary Term Definition Active Scan StateThe state when the radio is in Scan Mode, and when the radio is rapidly moving through the Scan List Member channels looking for eligible transmission activity. Busy Channel Lockout (BCL)If BCL is activated, the radio will check for channel activity before trans- mitting. If activity is detected, transmission is prohibited. For carrier squelch mode, radio will not transmit, if it is receiving carrier. For coded squelch mode, it will not transmit, if it is receiving carrier with different PL/DPL code. CarrierAn electromagnetic signal that is transmitted on a selected frequency for the purpose of carrying voice or data transmissions along with it. Carrier can then be received by all radios listening on that frequency. Carrier Squelch (CSQ)When the carrier energy exceeds the carrier energy threshold, known as the Squelch Level, the radio unmutes. CDCompact Disk. Channel A single path separated by frequency or time divisions used for transmit- ting and/or receiving voice and/or data. Channel AliasChannel Aliases are radio-user descriptions for the radio’s channels. Alphabets, numbers, spaces, “+”, “-”, and “/” can be used. Examples: EMT-001, 500, SECURITY. Channel Band- widthThe channel spacing when operating on the current channel. Channel EnabledWhen selected, the channel is enabled and accessible. Coded Squelch When the channel receives incoming message that contains the same PL or DPL code as its Rx PL/DPL code, the radio unmutes. CodeplugA solid-state chip inside a radio where the radio’s personality data is stored. Communications Port (COM Port)A serial hardware interface connection at the back of a computer used to communicate with other hardware devices, such as radios, modems, and printers. Also known as a Serial Port. COM Ports are designated by slot positions such as Port1, Port2, Port3, Port4. When programming a radio, the computer is connected to the radio with a RIB cable via the COM port. The computer’s CPS Com Port settings are independent of each other and apply to the Read and Write features. CPSAcronym for Customer Programming Software. Licensed Motorola soft- ware used to program two-way radios with a unique set of features. CSQ Carrier Squelch. CTCSSAcronym for Continuous Tone Coded Squelch System. A generic term for sub-audible tone/ code used to create communications groups. Also see PL.
March, 20066881096C38 Glossary-2 Digital Private Line (DPL)DPL is a digital format transmitted along with the carrier. DPL allows for more use and privacy on a frequency. DPL is transmitted at a sub-audi- ble (not able to be heard) frequency. DPLDigital Private-Line™ EEPROM Electronically Erasable/Programmable Read-Only Memory: used by the radio to store its personality. FirmwareSoftware, or a software/hardware combination of computer programs and data, with a fixed logic configuration stores in a read-only memory. Information cannot be altered or reprogrammed. FGU Frequency Generation Unit. Frequency(a) The location of the center of a channel of operation in the radio spec- trum. Measured in Megahertz (MHz). (b) A computer speed. Measured in Megahertz (MHz). Hard Pot Hardware potentiometer for adjustment of parameter settings. Home ChannelThe channel where scan is started. Landed Scan State When the radio is in Scan Mode, and once Active Scan finds an eligible Scan List Member channel/call to receive or unmute to, the radio is then in Landed Scan State. Also, once both Transmit and Receive activity has ceased, and while the Scan Hang Timer is counting down, the radio is still in Landed Scan Mode. Latest Codeplug Ve r s i o nThe most recent version number of codeplug information that was loaded into the radio. This is stored in the radio’s codeplug. LCD Liquid Crystal Display: a module used to display the radio’s current oper- ating channel info or status message. Long Press FunctionFunction that is invoked if the button is pressed and released after one second. Lower Scan FrequencyThe lower limit that VFO will scan. Maximum FrequencyThe highest frequency setting at which the radio is allowed to operate. The radio’s frequency range is defined as being between, or equal to, the Minimum and Maximum frequencies. This information is stored in the radio’s codeplug. Minimum FrequencyThe lowest frequency setting at which the radio is allowed to operate. The radio’s frequency range is defined as being between, or equal to, the Minimum and Maximum frequencies. This information is stored in the radio’s codeplug. Model NumberThe model number identifies the type of radio. This information is stored in the radio’s codeplug. Normal Scan For Normal Scan, the radio assigns equal priority to all members in the Scan List selected for the current channel. When the radio is scanning a Scan List (Active Scan), all scan list members (including the Home Channel) will be allocated equal time to be scanned. For example, if the Home Channel is H1, and the Scan List Members are Nn, then the scan- ning sequence is: N1, N2, N3, ..., H1, N1, N2, ..., etc. Term Definition
6881096C38March, 2006 Glossary-3 Offset FrequencyIf Tx Offset is set to Positive, this frequency will be added to the VFO Rx Frequency when radio is transmitting. It will be subtracted from the VFO Rx Frequency if Tx Offset is set to Negative. Original Codeplug Ve r s i o nThe first version number of codeplug information that was loaded into the radio. This is stored in the radio’s codeplug. PC Board Printed Circuit Board. PL Private-Line® tone squelch: a continuous sub-audible tone that is trans- mitted along with the carrier. PLLPhase-Locked Loop: a circuit in which an oscillator is kept in phase with a reference, usually after passing through a frequency divider. Pretime Selects the amount of time between PTT button press and the first digit of ID transmission. This time allows the receiving radio to stabilize before receiving data. Priority ScanFor Priority Scan, the radio assigns the highest priority to the first mem- ber in the Scan List selected for the current channel. When the radio is scanning a Scan List (Active Scan), 50% of the scans are targeted at the Priority #1 Member channel. For example, if the Priority #1 Member is P1, and the non-priority Scan List Members are Nn, then the scanning sequence is: P1, N1, P1, N2, P1, N3, P1, N4, P1, N5, etc. Priority #1 Scan List MemberThe first member in the current Scan List. When the radio is scanning a Scan List (Active Scan), 50% of the scans are targeted at the Priority #1 Member channel. Example: If the Priority #1 Member is P1, and the non-priority Scan List Members are Nn, then the scanning sequence is: P1 N1, P1 N2, P1 N3, P1 N4, P1 N5, etc. Note: When the radio’s speaker is unmuted to a non-priority call (Landed Scan mode), the radio continues to mute at a specific time interval (the Scan Interval Time), and scan for transmission activity on the Priority #1 Member channel. If the radio discovers a valid Priority #1 transmission, it drops the current transmission, and unmutes to the Pri- ority #1 call. Priority Scan has to be enabled (per channel) for this fea- ture to function. Prime Channel Return Hang TimeThe amount of time that the radio will stay idle in another channel before reverting back to the Prime Channel. Private Line (PL) A sub-audible tone/code used to create unique/private communication groups while operating in Conventional Dispatch mode. A generic term for Tone Private Line (TPL), or Digital Private Line (DPL). ProgramThe transfer of CPS information from the computer’s temporary memory (RAM) to the radio. PTT Push-To-Talk: the switch located on the left side of the radio which, when pressed, causes the radio to transmit. Random Access Memory (RAM)A temporary storage space used by a computer to operate a software program currently running. Anything stored in RAM is lost when the computer is turned off. Registers Short-term data-storage circuits within the microcontroller. Term Definition
March, 20066881096C38 Glossary-4 RepeaterRemote transmit/receive facility that retransmits received signals to improve communications coverage. RESET Reset line: an input to the microcontroller that restarts execution. RF PARadio Frequency Power Amplifier. Radio Interface Box (RIB)Used to connect a personal computer to a radio for the purpose of com- munication between the two. The RIB consists of level-shifting circuits that convert from the standard RS-232 voltage levels of the computer asynchronous serial interface (COM Port) to the single-ended voltage levels present on the Serial Bus contacts of the radio’s connector. The RIB must have an appropriate RIB-to-radio and RIB-to-computer Radio Interface Cable for communication and radio programming to occur. Receive Fre- quencyA designated frequency used when receiving carrier for the current channel. Reverse Burst / Turn Off CodeCauses a Tone Private Line (TPL) or Digital Private Line (DPL) code to be transmitted at the end of a transmission - once PTT is released, and while operating on the current channel. This sub-audible tone causes the receiving radio to mute its speaker before loss of a carrier is detected. Muting the speaker eliminates unwanted noise (squelch tail) during loss of carrier detection. ROMRead Only Memory. RSSI Received Signal-Strength Indicator: a dc voltage proportional to the received RF signal strength. RPT/TARepeater/Talk-Around. Rx DPL Code The specific code accepted when receiving Digital Private Line (DPL) encoding, while operating on the current channel. Rx DPL InvertSetting Rx DPL Invert causes Digital Private Line (DPL) signals to be inverted when they are received by the radio, while operating on the cur- rent channel. Inverted coding allows for more traffic/usage on frequen- cies. Rx TPL Frequency A designated frequency used when receiving Tone Private Line (TPL), while operating on the current channel. This frequency can directly cor- relate to the Rx TPL Code field; however, non standard code frequen- cies may also be selected. Scan ListThe Scan List determines which channels the radio scans, when operat- ing in the Scan Mode, on the current channel. Scan List Member The Scan List allows you to select the grouping of channels that make up the current Scan List Member channel. This grouping of a Scan List Member channel can then be scanned for transmission activity - one at a time, when the radio is in Scan Mode. A Scan List can have a maxi- mum of 16 Scan List Members. Scan List Member scanning priority is definable. A Scan List can be assigned to a channel. One Scan List is available. Scan ModeWhen the radio is in one of the two Scan States: Active Scan and Landed Scan. This mode is initiated when the programmable SCAN but- ton is pressed. Term Definition
6881096C38March, 2006 Glossary-5 Scan Type There are two types of scanning available on the current Conventional Personality: Normal Scan or Priority Scan. Serial NumberEach radio has its own unique serial number. This information is stored in the radio’s codeplug. Short Press FunctionFunction that is invoked if the button is pressed and released within one second. SoftpotSoftware Potentiometer: a computer-adjustable electronic attenuator. Software Computer programs, procedures, rules, documentation, and data per- taining to the operation of a system. SquelchMuting of audio circuits when received signal levels fall below a pre- determined value. Squelch Level The amount of carrier energy required to unmute the radio’s speaker upon satisfying the selected Carrier Squelch threshold. Low level allows more transmissions with less clarity to unmute the radio’s speaker. High level increases the squelch threshold causing a stronger carrier signal to be required before the radio’s speaker will unmute. This helps to reduce unwanted noise. Tone Private Line (TPL)Transmitted when the receiving radio is to only receive calls from radios with specific TPL codes, this creates communications groups while operating in Conventional Dispatch mode. TPL allows for more use and privacy on a frequency. TPL is transmitted at a sub-audible (not able to be heard) frequency. Also known as CTCSS. TOT Time-Out Timer: a timer that limits the length of a transmission. TPLTone Private-line. Tx DPL Code The Digital Private Line (DPL) code that transmits while operating on the current channel. Tx DPL InvertSetting Tx DPL Invert causes Digital Private Line (DPL) signals to be inverted before they are transmitted from the radio, while operating on the current channel. Inverted coding allows for more traffic/usage on fre- quencies. Tx Frequency A designated frequency used when transmitting carrier for the current channel. Tx OffsetThe offset that will be added to the VFO Rx Frequency when radio trans- mits in VFO mode. Available options are: None (transmits using Rx Fre- quency), Pos (transmits using Rx Frequency + Offset Frequency), Neg (transmits using Rx Frequency - Offset Frequency), User (transmits using the User Defined Tx Frequency). Tx Power The transmit power level while operating on the current channel. High: Used when a stronger signal is needed to extend transmission distances. Low: Used when communicating in close proximity, and to keep the radio from transmitting into other geographical groups operat- ing on the same frequency. Term Definition
March, 20066881096C38 Glossary-6 Tx TPL FrequencyA designated frequency used to transmit Tone Private Line (TPL) encod- ing, while operating on the current channel.

Unmuting A radio unmutes, when it opens its speaker to receive audio. µPMicroprocessor. Upper Scan FrequencyThe upper limit that VFO will scan. User Defined PL FrequencyYou can customize up to three non standard PL frequencies to provide more choices for PL. VCO Voltage-Controlled Oscillator: an oscillator whereby the frequency of oscillation can be varied by changing a control voltage. VFOVariable Frequency Operation. The radio user chooses frequencies instead of preprogrammed channels to operate the radio. VFO Scan Radio scans the preprogrammed frequency range defined by VFO Upper Scan Frequency and Lower Scan Frequency in the increment defined by Frequency Step Size. VHFVery High Frequency. VSWR Voltage Standing Wave Ratio. Term Definition
