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...

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...

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-...

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...

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.

March, 20066881096C38 Glossary-6 Tx TPL FrequencyA designated frequency used to transmit Tone Private Line (TPL) encod- ing, while operating on the current channel. This frequency can directly correlate to the Tx TPL Code field; however, non standard code frequen- cies may also be selected. µC Microcontroller. UHFUltra High Frequency. 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...
