ES2C-TTL – Ethernet & WiFi TTL Serial Converter 2 Channels

The ES2C-TTL offers the same capabilities as the ES2C: Ethernet connectivity, expanded voltage regulator range (6 to 23V), optimized firmware, built-in webserver, and support for TCP/IP, HTTP via API, and MQTT protocols. The difference is the serial interface: instead of RS232 (DB9) ports, the device provides two TTL serial ports (TX, RX, and GND), enabling direct connection to equipment that already operates at TTL logic levels — without RS232 adapters.

Ideal for integrating scales such as UPX EA-15, ACQUA, and Toledo Prix 3, as well as printers, microterminals, and other TTL-compatible devices.

Data received from the network is transmitted to the serial port, and data sent by the serial port is transmitted over the network.

Configuration is straightforward through a built-in webserver, accessible via browser after connecting to the Wi-Fi network created by the converter itself or via Ethernet. You can set network parameters, login credentials, Wi-Fi operation modes (AP, STA, or AP+STA), and individually configure each serial port with baud rate, parity, stop bits, and more.

With support for firmware updates, physical button for restart/reset, LED status indicators, and a comprehensive system status dashboard, the ES2C-TTL ensures stability, ease of use, and full control over your serial communication.

Highlight: Easy HTTP via API and MQTT integration. Integration can be tested and validated via TGY Cyber Suite software (free).

Testing tool compatible with Windows 10, 11 and macOS with M1 chip or above.
