    (herein referred to as the Cresnet system) peripheral or as a “smart” peripheral. As a standard Cresnet system peripheral, the CN-TVAV can be added as a Cresnet network device to a host Crestron control system with all logic, infrared (IR) drivers, and serial strings stored in the control system programming logic.

  • Page 6: Physical Description

    (no IR driver loaded in the CN-TVAV). It is not recommended to communicate to a port of the CN-TVAV (such as the IR Port) through a program in the CN-TVAV itself and via a host control system at the same time.
  • Page 7 Crestron CN-TVAV CN-TVAV Physical Views CN-TVAV Ports Each CN-TVAV rear panel port has a silk-screened label. For the descriptions of the ports, refer to the two diagrams below and the paragraphs on the next two pages. CN-TVAV Rear Panel CNI-TVAV (International Version) Rear Panel Operations Guide - DOC.
  • Page 8 This 3.5mm mini-jack is used by the STIRP (provided) to control an attached TV or AV device. The jack accepts mono (2-conductor) or stereo (3-conductor) mini-plugs. Multiple IR drivers may be loaded into the CN-TVAV and, with the use of a Crestron ST-SPL IR Splitter, up to five AV devices may be controlled.
  • Page 9 OFF or ON, a large current is used to indicate that the attached device is ON and the absence of (or very low) current indicates the device is OFF. If the CN-TVAV (or control system) detects that the device is ON, the program can be coded to not allow the CN-TVAV to attempt to turn it ON, which would inadvertently turn it OFF.

    NOTE: The IR receiver, for use with an optional Crestron handheld IR transmitter, is located behind the red lens between the RS-232 and IR IN indicators. IR IN This LED (red) illuminates when the CN-TVAV receives a valid IR code from an optional Crestron handheld transmitter. Leading Specifications The table below provides a summary of leading specifications for the CN-TVAV.

    If the unit is a home-run from a Crestron system power supply network port, the load factor of that unit is the load factor of the entire run. The length of the run in feet and the load factor of the run should be used in the resistance equation below to calculate the value on the right side of the equation.

  • Page 13: Programming Cable Fabrication Specifications

    In the event that modular cables or RJ11 to DB9F adapter is not available to program the CN-TVAV at the RS-232 port, the table below and the diagram on the next page are provided so that the cable can be fabricated.

  • Page 14: Special Considerations For Using The Rs-232 Port For Uploading Programs

    Special Considerations for Using the RS-232 Port for Uploading Programs The CN-TVAV has a single RS-232 console port that is used for uploading programs and communicating with RS-232 equipment for control purposes. Since the port is shared, the operation is slightly different from standard Crestron control systems that have a dedicated RS-232 console ports.

  • Page 15: Cable Configuration For Normal Operation

    Cable Configuration for Normal Operation When operating the CN-TVAV under normal conditions, refer to the figure on the next page for a typical connection diagram. WARNING: When the POWER IN cord is plugged into an energized outlet, POWER OUT becomes energized.

  • Page 16: Identity Code

    CN-TVAV in the Cresnet system needs a NET ID that matches an ID code specified in the SIMPL Windows program. The NET ID of the CN-TVAV is factory set to 50. The NET IDs of multiple units must all be unique and changed from a PC via SIMPL Windows or VisionTools™...

    Import an Archived (ZIP File) Program Dialog Box File Types There are quite a few file types involved with Crestron explains the different types that might be encountered in each directory. In many cases, the supplied software is grouped into a number of subdirectories. The intent is to keep files organized.
  • Page 20 Userdb Subdirectory - The files (described in the table below) in this subdirectory is a user database IR driver that is needed to interface with certain IR-controlled devices. This driver differs from Crestron database IR drivers in that the former are included as part of a Crestron Database.
  • Page 21 Usrmodule Subdirectory - The files (described in the table below) in this subdirectory are user modules, or special sub-programs that are integral parts of the main program. These differ from Crestron modules in that the former are supplied as part of the development software.

  • Page 22: Obtaining Communications

    Programmable TV/AV Controller Obtaining Communications To upload program files to the CN-TVAV, it is necessary to first obtain communication with the device. Communication with the CN-TVAV is established via the local RS-232 port and is required to set IP address initially.
  • Page 23 Port Settings dialog box. 6. Select the appropriate connection type. (If using the RS-232 port of the CN-TVAV for the connection to the PC, refer to “Special Considerations for Using the RS-232 Port for Uploading Programs” on page 10 for further information.) Verify that an available COM port (COM 1 is shown below) is selected.

    SIMPL (Symbol Intensive Master Programming Language) is an easy-to-use programming language that is completely integrated and compatible with all Crestron system hardware. The objects that are used in SIMPL Windows are called symbols. SIMPL Windows offers drag and drop functionality in a familiar Windows environment.

  • Page 34: Problem Solving

    Internal Fuse Replacement The circuitry of the CN-TVAV is electrically protected by an internal fuse. If the fuse blows (opens), no power is provided to the circuitry (the POWER OUT receptacle remains energized). To replace the fuse, perform this procedure. The only tools required are a grounding strap (or grounded work station) and a #1 Phillips tip screwdriver.
  • Page 35 POWER IN cord. Disconnect power by pulling the POWER IN plug from the source. NOTE: The internal fuse only protects the CN-TVAV circuitry. This fuse does not protect the POWER OUT receptacle. NOTE: Although not required, it is recommended to label and disconnect each cable (POWER IN line excluded) from the rear panel ports of the CN-TVAV.
  • Page 36 Install Replacement Fuse NOTE: The inner-most screw holes of the cover and CN-TVAV are machined for unit rack mounting and do not accommodate the cover screws. Do not install the cover screws into the inner-most screw holes.
