Questions and answers
we have a problem with device MM300. it says that the device is invalid through the software and does not read the device. the communication is through RS 485. is it possible to give us an advice or send us some reccomendations or instructions?
For a GE MM300 device that is not recognized by software and communicates via RS485, follow these troubleshooting steps:
1. Ensure correct RS485 wiring:
- Use two-wire RS485 in a daisy chain configuration.
- Install a 120 Ohm resistor in series with a 1 nF ceramic capacitor at each end of the link.
- Use shielded wire and ground the shield at only one location.
2. Check device addressing and termination:
- Confirm proper device address and ensure no address conflicts.
- Verify that termination networks are correctly installed at both ends.
3. Confirm half-duplex communication:
- Ensure that the system supports half-duplex communication and not sending and receiving data simultaneously.
4. If using USB for setup (e.g., USB-to-RS485 converter) and the device is not recognized:
- Repeat the connection procedure 2–3 times.
- If still not recognized, uninstall the USB driver from Device Manager under modems.
- Disconnect the USB cable, wait at least 10 seconds, then reconnect.
- When prompted by the Hardware Wizard, select "No, not this time," then "Install the software automatically," and press "Continue Anyway."
- Finish the installation and check if the USB device appears in the setup software.
These steps help ensure proper hardware connection and correct software recognition of the MM300 device.
