EM2001 as a 4-port Serial-over-IP Board

The EM2001 is a Tibbo BASIC/C-programmable IoT board with Ethernet, as well as optional Wi-Fi* and GPRS** connectivity. The EM2001 has four independent UARTs. The board offers substantial speed and functionality improvements over its predecessor — the original EM1001 device.

The EM2001 may be uploaded with a fully functional serial-over-IP (SoI) application that turns the board into a powerful four-port serial-over-IP (SoI) device.

All three network interfaces — Ethernet, Wi-Fi, and GPRS — are fully supported by the SoI application, with automatic switchover depending on the network conditions.

As an SoI converter, the EM2001 is compatible with Tibbo Device Server Toolkit (TDST) for Windows. TDST includes the Virtual Serial Port Driver (VSPD), which enables you to use all four serial ports of the board as remote COM ports of your PC. The Linux version of the VSPD is available as well.

The board is self-sufficient — it does not require a host PCB to plug into. The RJ45 jack is mounted directly on the board. The EM2001 also contains a DC-DC regulator that can power the board and has additional current budget for external hardware.

* Requires the GA1000 Wi-Fi add-on, which can be connected externally or piggybacked on top of the EM2001.

** Requires a standard GPRS modem (i.e. Simcom's SIM900), to be connected to the UART #4 of the EM2001.

Key Features

(with the GA1000 add-on)

Optional GPRS connectivity (requires an external modem)
Onboard DC-DC regulator (8 ~ 20V in, 3.3V out); 3.3V power input and output
Onboard status LEDs and MD (setup) button



  • 10/100Base-T auto-MDIX Ethernet port with RJ45/magnetics.
  • Optional Wi-Fi interface (requires the GA1000 add-on module).
  • Can control a GPRS modem* (such as the SIM900).
  • Four high-speed serial ports (CMOS-level):
    • Baudrates of up to 460,800bps;
    • None**/even/odd/mark/space parity modes;
    • 7** or 8 bits/character;
    • Full-duplex mode with RTS/CTS and XON/XOFF flow control;
    • Half-duplex mode with direction control;
    • Encoding and decoding of Wiegand and clock/data streams.
  • 32-bit architecture.
  • Three onboard LEDs:
    • Red and green status LEDs;
    • Yellow Ethernet status LED.
  • Two control lines for connecting external status LEDs.
  • Onboard MD (setup) button.
  • Reliable power-on/brown-out reset circuit.
  • Powering options:
    • Through the switching regulator, 12VDC nominal (8 ~ 20V);
    • Using regulated 3.3V power (the regulator is bypassed).
  • The regulator can provide up to 1.3A @ 3.3V to external devices.
  • Power: 100mA @ 3.3V (100Base-T mode).
  • Dimensions (LxWxH): 75x36x17.5mm***.
  • Operating temperature range: -40 ~ +80°C.
  • Firmware is upgradeable through the serial port or network.

*Must be connected externally.

**The EM2001 does not support the combination of the 7 bits/character mode and the "none" parity mode.

***Not including RJ45, power jack, GA1000.
