Figura 3.1: Dimensions for EID051-133/134/135/143/144/145 (top) and EID051-138/148 (bottom) models. The EID051-133 (3 Digits 0.36 inch) model corresponds to the smaller unit shown at the top, with approximate dimensions of 60.3mm x 28.8mm for the front panel and 15mm depth.
3.2 Cablejat
Connect the power supply and RS485 communication lines to the display's terminals. Ensure correct polarity for the power supply, as the device includes reverse connection protection. Refer to the product's pinout diagram (if available, otherwise general RS485 A/B and power +/- connections).
- Font d'alimentació: Connect to the designated power input terminals. The device features a wide input voltage gamma.
- Comunicació RS485: Connect the RS485 A and B lines to the corresponding terminals.
4. Instruccions de funcionament
This section details how to configure and operate your EID051 display using the Modbus RTU protocol.
4.1 Modbus RTU Communication
The display communicates via Modbus RTU. Ensure your master device (e.g., PLC, HMI) is configured with matching communication parameters (Modbus address, baud rate, check digit).
- Adreça Modbus: Can be set from 1 to 255. This address identifies the display on the RS485 bus.
- Velocitat de transmissió: Supports standard rates from 1200bps to 115200bps.
- Check Digit: Configurable parity settings (e.g., None, Even, Odd).
Refer to the specific Modbus register map provided with the product documentation for details on writing data to display and configuring parameters.
4.2 Personalització de la pantalla
The EID051 offers several options for customizing its display behavior.
- Ajust de brillantor: The display supports 8 levels of brightness. This can typically be adjusted via Modbus commands or potentially through the host computer software.
- Power-on Initial Display: Configure what the display shows immediately after power-up. Options include displaying '0', the device's 485 address, a specified custom content, or having all digital tube segments lit.
- Blinking Function: Activate blinking for specific digits or the entire display. The blinking cycle can be customized to user habits and site requirements.
Figura 4.1: The EID051 display offers 8 distinct brightness levels, allowing users to adjust visibility according to environmental conditions and preferences.
4.3 Host Computer Software
EBYTE provides supporting host computer software to facilitate testing, parameter modification, and restoration of factory settings. This software offers a user-friendly interface for managing the display's configurations.
5. Manteniment
The EID051 display is designed for industrial environments and requires minimal maintenance.
- Neteja: Gently wipe the display surface with a soft, dry cloth. Avoid using abrasive cleaners or solvents that could damage the display or casing.
- Condicions ambientals: Ensure the operating environment remains within the specified temperature and humidity ranges (-45°C to 85°C).
- Actualitzacions de firmware: Check the EBYTE official website periodically for any available firmware updates that may enhance performance or add new features.
6. Solució De Problemes
If you encounter issues with your EID051 display, refer to the following common troubleshooting steps.
| Problema | Causa possible | Solució |
|---|---|---|
| Display is blank or off. | No power, incorrect wiring, or power supply issue. | Verify power connections and supply voltage. Check for reverse polarity. |
| Incorrect or garbled display. | Modbus communication parameters mismatch, incorrect data format. | Check Modbus address, baud rate, and check digit settings on both the display and the master device. Ensure data sent is in the correct format (e.g., ASCII, integer). |
| Display not responding to commands. | Modbus address conflict, wiring issue, or master device problem. | Confirm unique Modbus address. Inspect RS485 wiring for continuity and shorts. Test with host computer software if available. |
| La pantalla parpelleja o és inestable. | Power supply instability, electromagnetic interference (EMI). | Ensure stable power supply. Check for sources of EMI and consider shielding or grounding improvements. |
