1.2 Software Description

You use the CP650 setup software to set up and configure the Dolby CP650 from a Windows PC. You can run this software while connected to a CP650 or as a stand-alone application. In either case, you can save parameter files on your local hard drive for later retrieval and editing.

1.3 System Requirements

The CP650 Setup Software runs on Windows 98, Windows NT 4.0, Windows 2000, Windows ME, and Windows XP. Your PC must be a 486-type or better and have at least ten MB of available disk space. Only a single instance of the application can run at one time.

Note: Chinese and Japanese versions of the setup software are supported for Windows 2000 and Windows XP operating systems only.

1.4 Connecting the Hardware

1. Connect an RS-232 serial cable (pin-to-pin) to any available serial port on your Windows computer.

2. Connect the other end to the SERIAL DATA port on the CP650 (either front or rear port).

Note: You can connect only one serial device at a time to the CP650.

Introduction Installing the Software1.5 Installing the Software

The CP650 setup software is provided on a CD-ROM.

Note: If an earlier release of the CP650 setup software is installed on your system, use the Windows Add/Remove Programs utility to remove the earlier version before installing the newer release. Older versions of the CP650 Setup Software may not work correctly with newer versions of the CP650 firmware.

To install the CP650 setup application, follow these steps:

1. Open the CP650 Setup folder and run CP650Setup_a_b_c_d.exe, where a_b_c_d refers to the software version number.

2. Select the desired language.

3. Follow the screen prompts until the installation is complete.

1.6 Launching the Setup Application

To launch the CP650 setup application, follow these steps:

1. Click the Start button and scroll to Programs. In the Dolby folder, select Dolby CP650 Setup.

The Dolby CP650 Setup window appears, as shown in Figure 1-1.

Figure 1-1 Dolby CP650 Setup Window2 Dolby CP650 Digital Cinema Processor Setup Software

Introduction Launching the Setup Application2. Select Communications Setup in the Action menu, then select the desired Com port for communicating with the CP650.

3. Select Connect in the Action menu to connect to the CP650. (For more information, see Section 2.2.2).

You may be prompted to send or retrieve the settings. (Normally, you retrieve settings.) Once connected, External Control Active should appear on the CP650 front-panel display.

4. Adjust the settings in the setup window on your PC.

When you select Connect from the menu or toolbar, the setup application attempts to connect the selected communications port on your PC to the serial interface on the CP650. After connecting, the setup application automatically retrieves the parameter file from the processor or prompts to retrieve or send settings. If you select Retrieve, a prompt tells you to save the current settings (the existing parameter file in your PC) prior to retrieving settings from the CP650. If you select Send, the parameter file from your PC is sent to the CP650.

Figure 1-2 Retrieve/Send Dialog Box

After connecting, you can adjust the settings using the Setup tabs. Any changes to the settings, such as moving a slider control, are reflected immediately in the current operation of the CP650. Changes are saved to the permanent CP650 flash memory when disconnecting or exiting from the setup software. If you turn off the CP650 before disconnecting from the setup software, any parameter changes are lost.

Note: This is different from operating through the front panel of the CP650. On the front panel, you must explicitly save each change by clicking the OK button before exiting the screen for that setting.

When connected, the Fader knob on the front panel is locked out and the Fader slider in the setup software is enabled; the Mute button remains functional.

Any adjustment modifies the open parameter file, and any attempt to exit or open a different file prompts you to save the current file.Dolby CP650 Digital Cinema Processor Setup Software 3
