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. This signal is interlocked with the AM and WX band selection inputs. That is, only one band can be selected at a time. The band will be set to whichever <bandselect> input goes high last. If the AM/WX tuner is not used, this signal can be left undefined. 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. The step rate is selected via the <FM_US/Europe> input. 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. When low, the frequency is set to US steps (100 kHz). When high, the frequency is set to European steps (50 kHz). The tuner stores the frequency selection in the EEPROM. High/1 = European mode; Low/0 = US mode (continued on next page) Operations Guide - DOC. 6233A FM Radio Tuner: C2N-TFM · 21 FM Radio Tuner Crestron C2N-TFM C2N-TFM Digital Input and Output Signal Descriptions (continued) SIGNAL TYPE AND NAME Input: <FM_Save_Preset> DESCRIPTION Saves the current station to the preset given by the <FM Presets> analog.
