EM1202EV
Introduction
The EM1202EV is a BASIC-programmable board designed primarily for serial-over-IP
and serial control applications. Being small enough to fit inside your product, the
board offers a rapid development alternative to using
, which require making
new host PCB. The EM1202EV can also be used to evaluate and test the
module it is based on.
The EM1202EV features a multi-channel serial port. The board has a single serial
port connector and is priced as a single-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 an additional serial channel. Don't want CTS and RTS either? That's one more
channel! In total, there are 15 different configurations to choose from.
The board is supplied in three versions offering various serial port and power options
(see below).
The EM1202EV is fully supported by TIDE software and a dedicated DS1202 platform
that covers all hardware facilities of the board (see TIDE, TiOS, Tibbo BASIC, and
Tibbo C Manual). The EM1202 platform can be used with the board as well. This
product ships preloaded with a fully functional serial-over-IP application. Written in
Tibbo BASIC/C, the application is compatible with Tibbo Device Server Toolkit
software, comes with full source codes, and can be modified by the user.
Available models
The board is supplied in three modifications.
The EM1202EV-RS is, essentially, a
device without its housing. The board
has a proper RS232 port (RS232 transceiver IC and DB9M connector), a power jack
and a power regulator ("12V"-to-3.3V), a pair of
and a
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 of the board can be used to supply 3.3V
power to the attached serial device as well.
Finally, the DS1206N-TS is like the "-TM" version but has no power jack and no
"12V"-to-3.3V power regulator. Instead, an attached serial device is supposed to
provide stabilized 3.3V power to the board.
