USB
The GW2345 includes a version 1.1 Device Controller interface. The interface
operates as a half-duplex, slave-only device at a baud rate of 12Mbps. The
interface does not operate as a USB host. A standard USB Type B connector is
provided on the board.
JTAG Port
A JTAG debug port is available to facilitate program download directly into Flash
memory. See Section 2.7 for instructions on using the Gateworks JTAG

Status LED and Push Button Reset
The GW2345 includes a status LED and a push button reset. The LED is
connected to the digital I/O and can be controlled by software. See Section 2,
Configuration and Installation for the mapping of the LED.
DC/DC Converter
A switching DC/DC converter is used to supply power to the GW2345. This
allows the board to support a wide input voltage range and low power operation.
The DC/DC has a minimum input voltage of 6VDC and a maximum of 28VDC.
DO NOT EXCEED THE 28VDC INPUT MAXIMUM OR DAMAGE MAY OCCUR
TO THE BOARD
. Also note that if a power over Ethernet injector is used to
power the board, there will be voltage loss due to the resistance of the Ethernet
cable. This should be taken into account when sizing the voltage supply.
