Features C H A P T E R Features What Is the C25 The C25 is a data decoder capable of decoding any of the ® following formats: APCO P25, MDC-1200 , and/or FleetSync . It is built to help fleet dispatchers/controllers to communicate with and manage their fleets. -
Page 9: Chapter 1 Feature
P25 ID’s and MDC-1200 ID’s can be displayed in Hexadecimal or Decimal format. Serial communications ports can be daisy-chained from one C25 channel card to the next channel card, eliminating the need for serial port combiners and buffers. Decodes and displays both the FleetSync fleet number and unit ID. - Page 10 Chapter 1 Features strings. Programmable display type permits "Taxi Bid", "Scrolling", and "Message and Assignment" presentations. Incorporates a real time clock so all received data can be time stamped. P25 decode qualification by NAC and/or TGID. External display clear connection can be attached to a footswitch to clear the display by a dispatcher without reaching for the decoder.

Optional features include: Aliasing The Alias feature is an extra option that allows the user to create a table that is used by the C25 to display an alphanumeric "Alias" instead of the actual received numeric ID. The created Alias Table is stored in the C25 and has a maximum of 9102 individual entries. - Page 13 Triple format decode The standard C25 is capable of decoding two signaling formats at the same time. The triple format decode feature can be added to permit decoding of three different signaling types on the same audio input line.

For factory use. JP-29 For factory use. The C25 is shipped configured for a High Z ground referenced system. Jumpers JP-13, 12, 11, 10, 9 and 8 set up attenuation circuits. Only one of these jumpers should be installed. JP-13, 12 and 11 are for unbalanced systems and JP-10, 9 and 8 are for balanced systems. -

Page 17: Data Output
GROUND Ground Data Output Data output is the signal out of the C25 when used in the Translator configuration. Data Out + is the high side and Data Out - is the low side. Data output is jumper selectable for single ended or balanced configurations. -
Page 18: Channel Busy
Channel busy can be used to qualify data mute. In COS Qualified muting, the associated radio is muted by the C25 until a valid MDC-1200 or FleetSync data decode. Once the data has passed, the radio is unmuted and remains unmuted until the Channel Busy line changes state. -
