Crestron ST-TUNE Integrated AM/FM/TV Tuner Integrated AM/FM/TV Tuner: ST-TUNE Description Functional Description The ST-TUNE is a Crestron remote control network (herein referred to as the Cresnet system) optimized high-performance AM/FM/WX (Weather radio) and television (TV) tuner. The ST-TUNE provides professional audio that connects directly to and is accessed by a Cresnet system. The Cresnet system can store virtually unlimited radio station and TV channel presets.
Integrated AM/FM/TV Tuner Crestron ST-TUNE Physical Description The ST-TUNE, shown below, is housed in a black enclosure with silk-screened labels on the front and rear panels. On the front panel are 12 light-emitting diodes (LEDs) for indicating the status of the unit, the digital display for showing the band, radio station or TV channel being received, two control buttons, and three function selection buttons. All connections are made on the rear panel ports.
Crestron ST-TUNE Integrated AM/FM/TV Tuner ST-TUNE Ports Each ST-TUNE rear panel port has a silk-screened label. For the descriptions of the ports, refer to the following diagrams and sections.

Integrated AM/FM/TV Tuner Crestron ST-TUNE AUDIO (L + R) This pair of RCA jacks output the left (white center insulator) and right (red center insulator) channel line-level audio to an audio processor such as the CNX-PAD8. The audio can also be connected to the audio inputs of a TV monitor, audio switcher and/or audio distribution equipment. VIDEO This RCA jack outputs composite TV video from the ST-TUNE.
Crestron ST-TUNE Integrated AM/FM/TV Tuner NET This LED (yellow) indicates that the SIMPL program currently loaded in the control system has a network device defined at the same NET ID code as the ST-TUNE. The LED flashes when communication with the Cresnet system and the ST-TUNE is occurring. BAND INDICATORS AND DIGITAL DISPLAY The AM, FM, WX (Weather Radio), or TV indicators contain four LEDs (red) to display the active band of the ST-TUNE.

Integrated AM/FM/TV Tuner Crestron ST-TUNE NOTE: Equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. The equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications.
Crestron ST-TUNE Integrated AM/FM/TV Tuner When calculating the wire gauge for a particular Cresnet run, the length of the run and the load factor of each network unit to be connected must be taken into consideration. If Cresnet units are to be daisy-chained on the run, the load factor of each unit to be daisy-chained must be added together to determine the load factor of the entire chain.
Integrated AM/FM/TV Tuner Crestron ST-TUNE NOTE: The location of the ST-TUNE is an important factor in the AM radio reception. The reception is also dependent on its placement and the construction of the building, locate the unit outside of any metal enclosures to achieve the best performance. A commercially available RCA extender cable (not supplied but RadioShack® part numbers 42-2352 and 274-874 are recommended), may be used to mount the antenna outside of a “shielded area or a “noisy” equipment rack.

Crestron ST-TUNE Integrated AM/FM/TV Tuner The next four sections describe a ST-TUNE within a SIMPL Windows program. The first section provides initial configuration information, the second section details the SIMPL symbol, the third section describes how a basic example program works by using a textual description and a block diagram, and the fourth section describes the screens of an advanced example program. NOTE: The following descriptions assume that the reader has knowledge of SIMPL Windows.
Integrated AM/FM/TV Tuner Crestron ST-TUNE NOTE: All signals listed in the following tables are DIGITAL signals unless noted otherwise. A digital signal can be high (logic level of 1), low (logic level of 0), and also have rising edge (when it goes from low to high) and falling edge (from high to low) transitions. Depending upon how the symbol was created, symbol inputs may work at the logic levels or on transitions.

Integrated AM/FM/TV Tuner Crestron ST-TUNE ST-TUNE and STI-TUNE Symbols Input Descriptions INPUT(S) FUNCTION(S) These signals perform the same functions as pressing the UP or DOWN buttons on the front panel. NOTE: The front panel buttons auto-increment after a preset period of time. These UP and DN signals engage only once on the rising edge. Therefore, in the TUNE mode, the UP signal increments the station once. This signal cycles through the AM, FM, WX, and TV bands.
Crestron ST-TUNE Integrated AM/FM/TV Tuner ST-TUNE and STI-TUNE Symbols Input Descriptions (continued) INPUT(S) WX-Station TV-Station FUNCTION(S) This analog signal is a number that sets WX frequency. Valid weather radio numbers are 16240d through 16255d. The number has an implied decimal point 2 digits from the end and must be sent in this format. For example, to go to 162.40, the analog number to be sent is 16240d. Valid WX station increments are by 1, such as 162.41, 162.42.
