[. . . ] Users can scan for stations by pressing the local up (k) and down (j) buttons on the C2N-TFM when the unit is in SCAN mode; or from remote buttons defined on a touchpanel or other interface. The tuner will scan up (+) or down (-) to a station, pause for five seconds, and then continue scanning to the next station. Pressing the local or remote scan button again will stop the scan operation. The scan operation also stops when: 1) the local BAND or MODE buttons are pressed; or 2) a remote band or search button is pressed; or 3) when it wraps around to the original station, if that station is scannable; or 4) if the original station is not scannable, after a maximum of repeat counts. High/1 (rising edge) = Scan up or down; Low/0 = No effect Output: <FM_Scanning> Indicates that the tuner is busy scanning. High/1 = Scanning; Low/0 = Not scanning Input: <AutoMute/AutoMono_Dis> Disables the auto-mute and auto-mono features in the FM tuner when the input is high. Auto mode automatically sets the tuner to mono as the signal strength weakens, and mutes the audio when the signal strength is weak. High/1 = Disable auto-mute and auto-mono mode; Low/0 = Enable auto-mute and auto-mono mode Inputs: <FM_Hphone_Vol+>, <FM_Hphone_Vol-> Increases (+) and decreases (-) the headphone volume on the rising edge of the signal. Users can control the headphone volume by pressing the local up (k) and down (j) buttons on the C2N-TFM when the unit is in VOL mode, or from remote buttons defined on a touchpanel or other interface. If the input is high for longer than 300 milliseconds, the volume will continue to increase or decrease until: 1) the input goes low (the local or remote volume button is released); or 2) after maximum "repeats". High/1 = Raise/lower volume (volume button pressed); Low/0 = volume button released (continued on next page) 20 · FM Radio Tuner: C2N-TFM Operations Guide - DOC. 6233A Crestron C2N-TFM FM Radio Tuner C2N-TFM Digital Input and Output Signal Descriptions (continued) SIGNAL TYPE AND NAME Input: <FM_BandSelect> DESCRIPTION Selects the FM band for as long as the input is high. Users can select the band by pressing the local BAND button on the C2N-TFM; or from a remote button defined on a touchpanel or other interface. The band will be set to whichever <bandselect> input goes high last. High/1 = Select FM band; Low/0 = Exit FM band Output: <FM_BandSelect-F> Indicates that the FM band has been selected via the local BAND button on the C2N-TFM. If the band is changed from a remote button, the feedback will not be returned on this signal. High/1 = FM band selected via local BAND button; Low/0 = FM band not selected via local BAND button Inputs: <FM_Station+>, <FM_Station-> Tunes the FM station up (+) or down (+) on the rising edge of the signal. Users can tune to stations by pressing the local up (k) and down (j) buttons on the C2N-TFM when the unit is in TUNE mode; or from remote buttons defined on a touchpanel or other interface. If the input is high for longer than 300 milliseconds, the tuner will continue to tune from station to station until: 1) the input goes low (the local or remote button is released); or 2) it wraps around to the original station; or 3) after maximum repeats. The tuner will jump in 100 kHz steps if in US mode; or in 50 kHz steps if in European mode. High/1 = Change station (tune button pressed); Low/0 = Stop station changing (tune button released) Input: <FM_US/Europe> Selects the FM frequency step rate.
