DS9122QA#

DS9488-GP8/DS9122x Evaluation System General Description The DS9488-GP8 multidevice programmer for 1-Wire® and I2C devices simultaneously programs up to 8 devices that use the 1-Wire or I2C bus programming interface. A variety of socket adapters (DS9122 series) allows one programmer to support multiple IC types. Software drivers for every supported device are quickly and easily installed. LED status indicators immediately identify the pass/fail status of individual devices. Configuration settings allow access to device-specific features such as memory protection, read/write permissions, authentication, etc. These can be store as a configuration profile and automatically loaded in subsequent programming sessions. A USB interface connects the programmer to any computer. A convenient Windows® application allows for easy operation of the programmer.

No socket adapters are included with the DS9488-GP8. A list of available sockets is provided on the DS9488-GP8 product page. Most socket adapters program a single device at a time and take up one socket site. Dual socket adapters cover two socket sites, but each IC has a dedicated set of status LEDs on the PCB as shown in Figure 1. The socket adapters employ ESD-sensitive components. Observe safe ESD practices when handling the socket adapters. Figure 1.

Unzip the downloaded file into an empty directory. While observing safe ESD practices, carefully remove the EV kit board from its packaging. Inspect the board to ensure that no damage occurred during shipment. Connect the DS9488-GP8 to a PC using the supplied USB A-to-Micro-USB B cable. All LEDs on the DS9488-GP8 momentarily illuminate. One or more LEDs might remain on. The EV kit must be connected during application installation. Click on the setup application to begin installation. Follow the installation instructions. If prompted, allow the DS9488-GP8 USB drivers to be installed. Install the desired device-specific drivers. Device-Specific Driver Installation Install device-specific drivers by using the application. 1) 2) 3) 4) 5) Download the compressed device-specific driver package from http://content.maximintegrated.com/ en/design/tools/applications/evkit-supplemental/. The package name incorporates the name of the device. For example, DS9488_Driver_DS2431 supports all packages of the DS2431. Navigate to the Application Setup tab and click on the Device Drivers radio button. See Figure 2. Click on the View Device Drivers button. Copy the driver package into the Device Drivers folder. Extract the .dll file and .pdf file for each device. The drivers in the Device Drivers folder are automatically loaded when the application is launched. To load a driver for immediate use, click on the Load Device Driver... button and select the drivers to install. Figure 2.

Install the socket adapters, and reapply power. The programming procedure has three steps: ●● Device configuration ●● Production file creation ●● Programming Device Configuration 1) 2) 3) 4) Navigate to the Device Configuration tab, shown in Figure 3. Select the device type to be programmed. Configure the device-specific options. Information about the options can be found in the IC data sheet and also in .pdf files under the Application Setup tab, View Device Help. If desired, click Save As... to record the configuration options. Figure 3. Device Configuration www.maximintegrated.com Maxim Integrated │  4 Multidevice Programmer for 1-Wire and I2C Devices DS9488-GP8/DS9122x Evaluation System Production File Creation The production file compiles all the configuration information and data into a single .xml file to be used by the programmer. After the device configuration has been input, press the Production File Create button and save the file to the folder defined in the Application Setup, File Outputs field. 3) 4) 5) The programmer offers the option to encrypt the production file for secure transfer between sites. Programming 1) 2) Populate the desired sockets. Navigate to the Programmer tab and select the active sockets as shown in Figure 4. An error is generated during programming if an active socket is not populated with an IC. 6) 7) Make sure the programmer is connected. If not, select Auto Detect under the COM button. Then click on the Connect button. The text below the Connect button indicates the programmer is connected. Load a previously generated production file using the Load Production File... button. Press either Start button on the programmer board or the Start button on the Programmer tab. The active LEDs on each socket board illuminate during programming and the progress bar advances. When programing is complete, the ALL PASS indicator on the programmer is green if all devices programmed and verified correctly. The indicator is red if any of the devices fail verification. The application keeps a running summary of the programming session. The cumulative results of each session are logged in the Outputs folder. Figure 4. Programming Dialog www.maximintegrated.com Maxim Integrated │  5 DS9488-GP8/DS9122x Evaluation System Figure 5 shows the application following a programming session in which sockets 1–5 are populated, and socket 4 failed post-programming verification. Figure 6 shows the programmer hardware after the same programming session with the pass/fail LEDs illuminated. Production File Encryption The application provides the option to encrypt production files so they can be securely transferred between a master (configuration) system and one or more programming systems. The application generates an RSA public/private Multidevice Programmer for 1-Wire and I2C Devices key pair that is used for the encryption and decryption. Figure 7 illustrates the procedure for generating and installing encryption keys and creating and loading an encrypted production file. One key pair should be created by the master system and shared among all the programming systems. The application loads both encrypted and nonencrypted production files if encryption keys are installed. Attempts to load an encrypted production file without first installing the encryption keys generate an error. Figure 5.

Two keys are generated in the Keys folder: • decryption_private_unsecured.key (unencrypted 1024-bit private key) • encryption_public.key (unencrypted 1024-bit public key) Install the public key on the master system by clicking on the Install Encryption (Public) Key button and selecting encryption_public.key. Securely transport decryption_private_unsecured. key to the keys directory of the programming system. On the programming system navigate to the Application Setup → Encryption Keys dialog. Click Install Decryption (Private) Key and select decryption_private_unsecured.key. This creates a new encrypted private key (decryption_private_secured. key) using the Windows Data Protection API that is unique to the production computer. Erase privkey_unencrypted.key from the programming system. Producing Encrypted Production Files 1) 2) 3) Load or create a configuration through the Device Configuration tab. Select the Encrypt option. Press the Create button. The production file is encrypted using the public key and placed in the outputs folder. www.maximintegrated.com Multidevice Programmer for 1-Wire and I2C Devices Troubleshooting Programming failures can sometimes be caused by incorrect settings in the Device Options dialog. Refer to the appropriate data sheet for details of the configuration options. The application keeps a detailed log of the programmer sessions, which can be used to troubleshoot problems.
