EM1202-EV BASIC-programmable Ethernet card.
The EM1202-EV is a card based on the EM1202 Ethernet module that converts 100BaseT Ethernet to a serial interface. This board offers a suitable solution for testing the EM1202 module and is also sufficient for the rapid development of devices.
Programmed with Tibbo BASIC, EM1202-EV is an inexpensive alternative to a development system, unlike expensive integrated computer platforms, such as motherboards with LINUX OS.
The EM1202-EV has three versions (-RS, -TM, -TS), which differ in the installed components — a detailed description is given below. EM1202-EV can be used to create stand-alone devices and for embedding in ready-made solutions.
Hardware Specifications:
-
- Compact, with a PCB size of 52.6x38mm.
- Two power supply options are possible: the input voltage regulator is 9-24V (RS, TM version) or 3.3V (TS version).
- 100BaseT Ethernet port.
- RS232 interface (-RS) or TTL-level (-TM, -TS) serial port (TX, RX, RTS, CTS, DTR, DSR).
- Two LED indicators embedded on the board (-RS).
- Reliable reset, even with insignificant and short-term power supply drops.
- The firmware is updated via both the serial port and the Ethernet interface.
- The EM1202-EV Starter Kit is available.
Possibility of programming in BASIC:
-
- Executable applications are developed in Tibbo BASIC.
- Absolute flexibility - imagine that the EM1202-EV is a miniature computer platform.
- Comes with TIDE - a complete development environment with a debug mode.
- Integrated web server (HTTP) with dynamic content.
- Numerous high-level, high-speed, and easily coded objects. Available facilities:
- Sock - Supports up to 16 TCP or UDP sockets;
- Ser - serial interface;
- Io - control lines of the serial port;
- Stor - read and write EEPROM;
- Romfile - attaching static (ROM) data to the project;

- EM1202-EV-RS ("RS" stands for "RS-232") includes an RS232 interface, an input voltage regulator, and built-in status indicators (LEDs). This board can be used, for example, to create a serial device server, such as the Tibbo DS100.
- EM1202-EV-TM ("TM" stands for "TTL Master") is installed in a serial device or PCB. The board has a TTL serial interface, as well as an input voltage stabilizer for 3.3V (up to 100mA).
- EM1202-EV-TS ("TS" stands for "TTL Slave") is also embedded in a device but does not have an input voltage regulator. Your board must provide a nominal input voltage of 3.3V and, optionally, a reset signal (not required for standard operation).
