Description: The DC440 is a powerful yet flexible instrument for decoding sub-audible and digital signaling tones as well as Touch-tone® characters. The DC440 monitors the demodulated audio output from a communications receiver, service monitor, scanner, or Interceptortm. The DC440 automatically decodes CTCSS tones and DCS codes. A unique feature of this instrument is that DTMF characters are also simultaneously displayed on the two line alpha numeric LCD. A serial data jack permits connection to a PC serial port using the OptoLinx interface. The DC440 has a complete set of control codes to permit operation from a PC. When used with a CI-V compatible communications receiver and PC, automatic monitoring of communications channels for tone and code usage is possible using ScanStar, ScanCat, or RCSI software. The DC440 has six operating modes for maximum flexibility. On power-up, the default mode permits automatic detection and display of 50 CTCSS tones 106 DCS codes, and 16 DTMF characters. When connected to the discriminator circuit of a communications receiver and a logical output from the squelch circuit, the DC440 can be used to automatically monitor tone and code usage and uncoded transmissions. Other modes include CTCSS/DTMF, DCS/DTMF, DTMF only, and Period measurement for monitoring non-standard tones. A squelch status indicator and decode activity indicator make the DC440 the most flexible and powerful instrument of its kind. Features Simultaneous off the air measurement of 50 CTCSS tones, 106 DCS codes, and 16 DTMF characters Six measurement modes for maximum flexibility Scrollable ten character display of up to 127 stored DTMF characters guards against data loss Convenient front panel controls for Power, Mode, and Recall Serial Data Interface, Use with OptoLinx interface to connect to PC serial port - Complete set of control codes for remote operation ToneLogtm Software option for automatic Time/Date Logging of Tone and Code usage Unique "On The Air" display when squelch breaks but no code or tone is transmitted Decoding Activity Indicator Compact Size Ideal for Mobile or Portable operation with optional internal NiCad battery Exceptional 2 line by 16 character back-lit LCD Display for optimal direct sunlight & low light viewing Precise switched capacitor audio filtering Uses ultra reliable OE10 counter IC to measure tones using period averaging technique
