| Development Phase | Valtoris Zero-Code Integration | Traditional In-House R&D (MCU + PHY) |
|---|---|---|
| Hardware Design | Drop-in ready. Solder the module or VT-CHIP100 directly. Impedance matching and transformers are pre-solved. | Requires complex PCB layout for high-frequency MAC/PHY lines and external isolation transformers. |
| Software Engineering | Zero coding required. Send data via standard UART/TTL. The chip autonomously handles all TCP/IP and Modbus framing. | Engineers must manually port LwIP, manage socket connections, handle memory allocation, and write CRC logic. |
| Testing & Debugging | Proven stability. 7th-Gen architecture running in millions of industrial nodes. No memory leaks. | Months of troubleshooting connection drops, buffer overflows, and watchdog resets under heavy network loads. |
| Time to Market | Hours to Days. Your core engineering team stays focused on your product’s actual application logic. | 3 to 6 Months. Diverts critical engineering resources into reinventing basic communication infrastructure. |

R&D Integration FAQ
Q1: Do I need to write a TCP/IP stack on my host MCU to use the VT-CHIP100?
A: Absolutely not. The VT-CHIP100 is a fully integrated SoC with an embedded hardware TCP/IP stack and MAC/PHY. Your host MCU simply communicates with our chip using standard UART (TX/RX) serial commands. We handle all Ethernet packet framing, ARP, ICMP, and TCP retransmission autonomously.
Q2: How do I configure the IP address and network parameters on the embedded module?
A: There are three ways. You can use our provided PC software (VirCom) over the LAN to search and set the IP; you can access the module’s built-in Web Server via a standard browser; or, for deep integration, your host MCU can send AT commands over the serial port to dynamically configure the module’s network settings on the fly.
Q3: Does the module support Auto-MDI/MDIX for Ethernet cables?
A: Yes. Our modules and the VT-CHIP100 support Auto-MDI/MDIX (auto-crossover). So end-users can plug in a normal, straight-through Ethernet cable or a crossover cable and the physical layer will auto-detect and auto-negotiate the correct link without breaking the network.
Q4: Can the chip handle RS485 transmit/receive direction control automatically?
A: Yes. If you are designing an RS485 interface, you do not need to write complex timing code on your MCU to toggle the MAX485 driver chip. The VT-CHIP100 has a dedicated pin for hardware control that goes high on transmission and low on reception, for perfectly timed half-duplex RS485 communication.
