100Mbps Ethernet Starter Kit, 4x serial, 32 digital I/O, BASIC/C US$94.00

EM1202-SK
100Mbps Ethernet Starter Kit, 4x serial, 32 digital I/O, BASIC/C


  • 10/100BaseT Ethernet Port
  • Compact size 52.6 38.0 mm
  • Up to 3.5 serial channels
  • RS232 or TTL serial versions available
  • Free serial-over-IP Tibbo BASIC application installed
  • The EM1202-SK is a 100BaseT Ethernet to serial board based on the EM1202 Ethernet module. The board provides a convenient way to test the EM1202 and is small enough to be used in production devices as a faster implementation alternative to modules. The EM1202/RJ1202 combination comes soldered on the board.

    Programmable in Tibbo BASIC and/or Tibbo C, the EM1202-SK offers a low-cost, rapid development alternative to expensive and complex computing platforms, such as Linux-based boards. It is a complete kit with EM1202EV board, serial cable (DB9F-DB9F for device-to-PC connection), Ethernet cable and a U.S. power supply.

    The EM1202EV is a programmable board designed primarily for serial-over-IP and serial control applications. It comes preloaded with a fully functional serial-over-IP application.

    The unique feature of the EM1202EV is its multi-channel serial port. There is a single serial port connector (either 12-pin header or DB9M depending on version; see below) capable of handling four independent serial channels. Have no use for those DSR and DTR lines? Turn them into RX and TX of an additional serial channel. Don't want CTS and RTS either? That's one more channel! In total, there are 15 different configurations or "port mappings" to choose from, starting from a standard single-channel configuration (RX, TX, CTS, RTS, DSR, and DTR) all the way to a 3.5-channel setup (RX, TX, RX2, TX2, RX3, TX3, and RX4).

    There are three configurations of the EM1202EV: The "RS" for RS232, the "TM" for TTL Master, and the "TS" for TTL Slave. You can select which version you require by using the drill-down option box at the bottom of this page. The image to the right shows the "RS" configuration.

    Serial-over-IP Controller Features

    • 10/100BaseT, auto-MDIX Ethernet port.
    • Up to 3.5 serial channels on a single connector.
    • 1024KB Flash memory for firmware, application, and data.
    • 2KB EEPROM for data storage.
    • Green and red status LEDs on top of the device. (RS version only)
    • Green and red status LEDs on the RJ45 jack.
    • Link and speed Ethernet status LEDs on the RJ45 jack.
    • Software-controlled onboard PLL to select the clock frequency.
    • Power ("RS" and "TM" versions): On-board regulator, 10-24V (12V nominal).
    • Power ("TS" version only): Direct 3.3V input (must be regulated to 5%).
    • Dimensions: 52.6 38 mm.
    • Firmware is upgradeable through the serial port or network.
    • CE and FCC approved.
    Serial port specifications:
    • Baud rates of up to 921,600bps.
    • None/even/odd/mark/space parity modes.
    • 7/8 bits/character modes.
    • Optional flow control.
    • Flexible mapping with 15 different options from single-channel to 3.5-channel.

    For details about the EM1202EV hardware and all the available serial port map settings, see the EM1202EV user manual.

    For details about programming the EM1202EV, see the Tibbo BASIC and Tibbo C documentation.

    Three configurations available

    The EM1202EV-RS has a proper RS232 port (RS232 transceiver IC and DB9M connector), a power jack and the power regulator ("12V" to 3.3V). There is also a pair of status LEDs on top of the board.

    The EM1202EV-TM is different from the "RS" version in that it has a TTL serial port and no status LEDs on top of the board. The port is accessible through a 12-pin connector on the PCB. The power regulator on the board can be used to supply 3.3V power to the attached serial device as well.

    The EM1202EV-TS is like the "TM" version but has no "12V"-to-3.3V power regulator. Instead, the attached serial device should provide stabilized 3.3V power to the board.
