    Model 420X Series. The manual also provides a description of the assembly and general maintenance procedures. 2.2. Equipment Overview The 420X series Solid State Programmable Attenuators provide for control via either USB or a variety of digital interfaces through the AUX mode connector, including parallel input (PIO), I2C, SPI, or a logic-level UART interface.

    3.4. DC Power Input The 420X series attenuators can be powered from either the USB VBUS (5V) or the AUX VDC input. While USB operates at a nominal 4.75V-5.25V range, the AUX VDC supply input can accept a wider range of voltage, from 3.3V-16VDC.

  • Page 10: Pio Mode

    MANUAL IM672 4.5.2 PIO Mode In PIO mode there are up to eight parallel digital input signals, D0-D7. Each input represents a dB value setting, with a logic low input = 0dB setting and a logic high = dB value for each control input as shown in the PIO column of the J1 AUX mode table.

  • Page 11: Spi And I2C Attenuation Data Format

    MANUAL IM672 I2C Device Address : fixed bits A3-A0 : addr bits R/W bit : WR=0, RD=1 A device address can also be assigned using the USB SET I2CADDR command which allows the use of all 7 D7-D1 address bits, with the exception of the reserved address 0. A software assigned address overrides the hardware A3-A0 pins and connections to these pins are ignored.
  • Page 12 MANUAL IM672 Compute the device address by combining the fixed upper portion, the addr pin setting, and the R/W bit=0 (write): DEV ADDR = (0b010 << 5) + (0b0100 << 1) + 0 = 0b01001000 = 72 = 0x48 Compute the programming value. Each bit represents 0.25dB, so setting = INT((dB * 100)/25), or simply multiply the dB value by 4 and use the integer result: VAL = 10.25dB * 4 = 41 = 0x29 = 0b00101001 There is only a single byte required, so this value should be programmed into register 3 (ATTN_HB)

  • Page 14: Aux Application Modes

    MANUAL IM672 4.6. AUX Application Modes 4.6.1 PIOSW Mode PIOSW (PIO single-wire) is a special subset of PIO mode that enables the rapid switching of attenuation between 0dB and max attenuation using a single input bit D0 (Pin 1). In PIOSW mode setting D0=HIGH sets the attenuator to its max dB value, while D0=LOW sets 0dB attenuation.

  • Page 15: Fade Mode

    MANUAL IM672 4.6.3 FADE Mode FADE mode allows the UUT to generate an attenuation ramp RF signal. The programmable settings in this mode include the start and stop attenuation values (FADE START/FADE STOP), the ramp increment value (FADE STEPSIZE), the ramp update interval time (FADE INTERVAL), and dwell and pattern repeat times (FADE DWELL/FADE TIME).
  • Page 16 MANUAL IM672 can communicate to a standard virtual COM port. Programming is done via simple ASCII text-based message strings to control the device (see the Command section later). For ease of use, the 4 has two modes of operation: console and raw mode. Console mode provides a simple command-line based interface that can be used in conjunction with any standard terminal emulator program.

  • Page 17: Command Operation

    MANUAL IM672 5. Command Operation Commands are comprised of text-based ASCII strings. The command parser is case-insensitive, so either upper or lower case characters are acceptable. Command parameters may be separated with either an ASCII SPACE char (0x20) or an ASCII COMMA char (0x2E), but the separator character used must be the same within an individual command string.

  • Page 32 MANUAL IM672 To verify that the driver has installed properly, view the Ports section in Device Manager. You should see the 420X listed as a USB COM port. Note the assigned COM port number. Using a terminal emulator, open a connection to the COM port shown above. The default COM port settings should be acceptable, as these are unused by the 420X.

  • Page 33: Awusbcdc.inf Installation File

    MANUAL IM672 The COM port numbers are assigned by Windows based on the device USB VID, PID, and Serial Number. The 420X uses VID 0x25EA and PID 0x106D. The attenuators are shipped with the USB serial number automatically assigned by the microcontroller. This serial number is a different number than that of the unit as a whole. 6.1.

    MANUAL IM672 6.2. Updating the 420X Firmware using USB HID Bootloader The USB HID Bootloader is a PC application that communicates with the onboard HID Bootloader of the 420X and allows updating the application program firmware of the 420X. In order to use this program, you will need to have the .NET framework version 4 installed on your computer. If you do not have.NET framework 4.0 installed, a non-descript error message will occur when trying to launch the executable, and the program will not open.

  • Page 36: Method 1

    MANUAL IM672 You can use one of two methods to set the 420X into HID bootloader mode: 6.2.1 Method 1 Connect a shorting jumper between the 10-pin TTL header connector pins 8 and 10. When you connect the 420X to the PC USB port it will power up in bootloader mode and the program should detect the device and read the chip configuration setup.
  • Page 37 MANUAL IM672 When the 420X boots into HID loader mode the bootloader app should detect it, retrieve configuration info from the device, and display a screen similar to: To download a new program, click ‘Open Hex File’ and navigate to the location with the HEX update file. Select the .HEX file and click ‘Open’.
