Product Description

The EM203 is an ultra-compact embedded networking module that bridges legacy serial communication with modern Ethernet networks. Acting as a transparent gateway, it allows TTL-level serial devices to communicate over 10/100Base-T, with robust real-time data handling and reliable packet delivery in space-constrained industrial applications.

Technical Specifications

Parameter Specification
Network Interface 10/100Base-T Ethernet (requires RJ203 jack/magnetics)
UART Baud Rates Up to 115,200 bps
Data Bits 7 or 8-bit
Parity Modes None, Even, Odd, Mark, Space
Flow Control Full-duplex RTS/CTS; Half-duplex with direction control
Visual Indicators 4 LEDs (Green/Red System, Yellow Link, Green 100 Mb)
External Signal Support 2 lines for external LED attachment
Power Consumption 220 mA at 5 V
Module Dimensions 30.1 × 18.1 × 5.5 mm

Integration and Environmental Design

  • Miniature footprint for embedding into sensor housings, motor drives, or custom M1 expansion boards

  • Supports RS485-to-Ethernet conversion with precise half-duplex timing control

  • Optimized for low-power operation in space-constrained industrial setups

Product FAQ

Q: Does the EM203 include the RJ45 jack?
A: No, it is the processing module itself; use with RJ203 jack/magnetics for network connection.

Q: Can this module be powered by 24 V industrial supply?
A: No, it requires regulated 5 V DC. A step-down DC-DC converter is needed when used in a 24 V environment.
