The EM1202EV is a BASIC-programmable board designed primarily forserial-over-IP and serial control applications.

Being small enough to fit inside your product, the board offers arapid development alternative to using modules, which require makingnew host PCB. The EM1202EV can also be used to evaluate and test the EM1202 module itis based on.

The unique feature of the EM1202EV is its multi-channel serial port.The board has a single serial port connector and is priced as asingle-port product, yet it packs four independent serial channels.Have no use for those DSR and DTR lines? Turn them into RX and TX of anadditional serial channel. Don't want CTS and RTS either? That's onemore channel! In total, there are 15 different configurations to choosefrom.

The board is supplied in three versions offering various serial portand power options. It comes preloaded with a fully functionalserial-over-IP application.


  • Three options: EM1202EV-RS, EM1202EV-TM, and EM1202EV-TS.
  • Based on the EM1202BASIC-programmable module.
  • 10/100BaseT, auto-MDIX Ethernet port.
  • Up to 3.5 serial channels:
    • EM1202EV-RS: RS232 port (DB9M connector);
    • EM1202EV-TM and "-TS": TTL serial port, 12-pin PCB connector.
    • Baudrates 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, such as:
      • A single channel: RX, TX, CTS, RTS, DSR, and DTR lines;
      • 3.5 channels: RX, TX, RX2, TX2, RX3, TX3, and RX4 lines.
  • 1024KB flash memory for firmware, application, and data.
  • 2KB EEPROM for data storage.
  • Up to six LEDs:
    • EM12-2EV-RS: Green and red status LEDs on top of the device;
    • 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:
    • EM1202EV-RS, "-TM": onboard regulator, 10-24V (12V nominal);
    • EM1202EV-TS: direct 3.3V input (must be regulated to +/- 5%).
  • Board dimensions: 52.6x38mm.
  • Firmware is upgradeable through the serial port or network.
