What Our Clients Say
Learn from our partners how our serial-to-WiFi converters have simplified their connectivity challenges.
“We had a batch of older PLCs that needed network access for remote diagnostics. Pulling new cables wasn’t an option. The Valtoris serial to Ethernet converter was straightforward to set up and has run without a glitch for over eight months. It didn’t require deep IT knowledge to get going—just worked.”
“Our building management system uses RS485 sensors, and WiFi coverage was spotty in the basement mechanical rooms. We tested a few adapters; some dropped connection under load. The Valtoris RS485 to WiFi unit held up, and their tech support helped us adjust the polling rate to match our system.”

Expert Guides To Industrial Wireless Connectivity
How To Choose The Right Serial-to-WiFi Converter For Your Needs?
- Identify your serial devices: Determine if you need to connect RS232, RS485, or RS422 equipment.
- Assess the environment:Harsh industrial environments? Choose a metal-case converter with -40°C to 85°C operating temp.
- Define security requirements: Ensure the device offers adequate encryption (e.g., WPA2-PSK).
- Prioritize support features: Look for built-in protections such as RS485 lightning protection and high EMI immunity.
What is the typical range and data rate of a Serial to WiFi Converter?
- Typical Operational Range: In standard indoor settings, 2.4GHz WiFi can reliably communicate up to 30-50 meters through walls.
- Data Transmission Rate: Sufficient for most industrial serial protocols, with serial baud rates up to 115.2kbps.
- For extended range: Deploy additional wireless access points or consider our LoRa DTU solutions.
Which Serial to WiFi Converter Is Best For Your Application?
- For demanding industrial environments, the Valtoris VT-WF100 (Metal Case) is recommended. Its support for RS232/485/422 and DIN-rail mounting makes it ideal for factory floors.
- For cost-effective RS485 conversion in less harsh environments, the Valtoris VT-WF110 (Plastic Case) provides simple integration for building automation and indoor equipment monitoring.
What Maintenance And Service Options Are Available For Valtoris’s converters?
- Valtoris ensures your wireless network remains operational through direct technical assistance for device pairing, network configuration, and troubleshooting.

Request Your QuoteFrequently Asked Questions
Why am I getting “Timeout” errors when sending Modbus RTU commands over the WiFi converter?
A: This is the most common issue when using standard transparent converters. Modbus RTU has strict timing requirements. If you simply transmit Modbus TCP bytes to a serial RS485 line, the timing breaks and the end device ignores the packet. Our converters (like the VT-WF100 and VT-WF110) solve this by featuring a built-in Modbus Gateway. They natively translate Modbus TCP requests to Modbus RTU, handling the checksums and timing locally to eliminate polling collisions and timeouts.
I wired RS485 A to A, and B to B, but my SCADA system shows no communication. What went wrong?
A: In the industrial world, the RS485 standard unfortunately does not clearly dictate which pin is A (+) and which is B (-). Many manufacturers label their driver lines backwards. If your baud rate and parity settings are identical but comms still fail, simply swap the A and B wires. This fixes the issue in 80% of field deployment cases without damaging the equipment.
How many serial meters can I daisy-chain to a single RS485 wireless converter?
A: The RS485 standard allows up to 32 devices to be connected to one daisy-chain bus. But when switching to wireless networks, polling 32 devices at once can cause delays. To get the best stability over WiFi, we suggest that you keep the number of devices per converter to less than 15–20 and make sure that both ends of the physical copper bus have 120-ohm termination resistors.
My legacy CNC monitoring software only connects via “COM1” or “COM2” and doesn’t understand IP addresses. Can I still use this?
A: Yes. Both the VT-WF100 and VT-WF110 support Virtual COM Port technology. We provide software (VirCom) that maps the converter’s network IP address to a virtual local COM port (e.g., COM5) on your Windows machine. Your legacy software will function exactly as it did before, completely unaware that the data is now traveling over a modern WiFi network.
