Corvus — Passer Configuration Utility

Corvus (Passer Programming Tool) is a client application for connecting to Passer-V2, Passer-T2, and Passer-Sch devices via Ethernet. It allows you to configure network and local parameters, calibrate registers responsible for device functionality, and collect and visualize data from tachometric inputs.

After writing changes, devices automatically apply them and restart with the updated configuration.

System Requirements​

  1. Windows 7 (x64) or higher
  2. External Ethernet port
  3. At least 8 GB RAM
  4. Graphics processor or video card for UI rendering

Getting Started​

Connecting to a Device​

  1. Connect the device to a 24 V DC, 0.4 A power source.
  2. Configure the PC network connection: static IP — 192.168.0.1, subnet mask — 255.255.255.0.
  3. Connect the device to the PC with an Ethernet cable.
  4. Launch Corvus.exe from the provided archive.
  5. In the IP field, enter the device address — 192.168.0.100 (default) and click Connect.

  1. Click Read — the table will display data from network parameter and calibration coefficient registers.
  2. Set the desired values in the second column of the table.
  3. Click Write — a success message appears in the bottom left.
  4. To save parameters to the device: click Write to FLASH, then Reboot.
Important

Wait 5–10 seconds between clicking Write FLASH and Go to Bootloader.

Network Configuration​

Open the Client Settings tab and set register values according to your requirements:

  • IP_ADDR — device IP address
  • NET_MASK — subnet mask
  • MAIN_GETWAY — default gateway
  • SERVER_IP — data collection server IP

Checking Inputs and Outputs​

To check AI1–AI8 channels (Passer-V2) or U1–U3, I1–I3 (Passer-T2), write 1 to registers CH1_AI_Enable – CH8_AI_Enable and click Write.

Figure 3 — Example of writing a value to a register

After writing, the AI LEDs on the front panel will turn green, indicating channel activation.

Figure 4 — Passer-V2 channel status

Open the Status tab to monitor AI/DO/DI channels. Without connected sensors, DO values will appear yellow. If a DO LED turns blue — a threshold value on a channel has been exceeded; the device requires inspection.

For Developers

Sections "Firmware Update" and "Calibration" are available in the developer documentation. Authorization required.

Tachometric Data Collection​

To work with tachometric inputs DI1–DI2:

  1. Open the Status tab, find registers CH1_DI_ENABLE and CH2_DI_ENABLE, write value 1.

  1. Open the Tachometric Collection tab.
  2. Select channels DI 1 and/or DI 2.
  3. To record to XLSX: enter the update frequency and click Start Recording, specify the file path.
  4. To stop recording, click Start Recording again.

Data Visualization​

  • Static graph output — builds a graph from saved XLSX file data.
  • Tachometer analyzer — displays real-time graphs from DI 1 and DI 2 for CH_DI_FREQ and CH_DI_Period parameters.
