2: Description and Specifications
The XPort Direct embedded gateway server is a complete network-enabling solution
enclosed within an RJ45 package. This miniature serial-to-Ethernet converter
empowers original equipment manufacturers (OEMs) to quickly and easily go to
market with networking and web page-serving capabilities built into their products.
The XPort Direct
The XPort Direct contains Lantronix's own DSTni-EX CPU, which has 256 KB zero
wait-state SRAM, 16 Kbytes of boot ROM, and an integrated 10/100 Ethernet
MAC/PHY.
The following diagram shows the side view of the XPort Direct with measurements in
inches.

PCB Interface
The XPort Direct has a serial port compatible with data rates up to 230 Kbaud. The
serial interface pins include +3.3V, ground, and reset. The serial signals usually
connect to an internal device, such as the UART port of the host device's
microcontroller. For applications requiring an external cable running with RS-232 or
RS422/485 voltage levels, the XPort Direct must interface to a serial transceiver chip.
