IntroductionThe EM1202-EV is a 100BaseT Ethernet to serial board based on the EM1202 Ethernet module. The board offers a convenient way to test the EM1202 and is also small enough to be used in production devices as a faster implementation alternative to modules. Programmable in Tibbo BASIC, the EM1202-EV offers a low-cost, rapid development alternative to expensive and complex computing platforms, such as LINUX-based boards. The EM1202-EV is supplied in three versions (-RS, -TM, -TS) that differ in the set of installed components- see bottom of page for details. The EM1202-EV can be used to create a standalone product or built right into your host device. Hardware Features

EM1202-EV-RS ("RS" stands for "RS-232") is intended for standalone designs, as it includes RS232 interface, switching power supply, and "top" status LEDs. This Board can be used, for example, to build an external Serial Device Server, akin to Tibbo's DS100.
EM1202-EV-TM ("TM" stands for "TTL Master") is intended to be installed inside your serial device (piggyback on top of your device's main PCB). The board has a TTL serial interface, and also can provide regulated 3.3VDC power (up to 100mA).
EM1202-EV-TS ("TS" stands for "TTL Slave") is also intended to be used inside your serial device, but it doesn't have a power regulator. Your serial board must provide 3.3VDC power and, optionally, a reset signal (not required for normal operation).
