2.3UARTConnectors&DebugPort
There are 3 UART ports (UART0, 4, 5) on EC1403/04 and 2 UART ports (UART0, UART4)
on EC1407/08/10. The connector type and functions are described in the table below:
UART

UART0 2x4 box
header RS232 signal level (TX, RX, RTS, CTS) RS232 port.
UART4 2x4 box
header RS485 signal level (485+, 485-) RS485 port. Note: RS485 port works only
in HALF Duplex mode.
UART5 2x4 box
header RS232 signal level (TX, RX, RTS, CTS) RS232 port. Note: EC1403/EC1404 only.
One 2x4 box header to DB9 cable is included in the product package. See Appendix A
for the detailed info of cable pin assignment.

UART1 (only TX, RX signals) is dedicated as a debug port.
The default setting of UART1 is: 115200 baud rate, 8 data bit, no parity, 1 stop
bit and no flow control.
A DB9 null modem cable (or adapter) is required when you would like to connect
UART1 to a PC that runs terminal emulation software such as TeraTerm.
UART0 (with TX, RX, RTS, CTS signals) works as a regular RS232 port.

Debug Port Connector:
The debug port on EC1400 device is a RS232 port for software development or for
Linux console port. Note that EC1403 and EC1404 debug port require a dedicated
debug cable which is included in the EC1403/EC1404 product package. See table
below:

2.4USBConnectors
The USB interfaces on EC1400 include a USB 2.0 OTG port (support 480Mbps speed)
and 2x USB1.1 host ports.
The USB1.1 host interface is connected to a hub controller to extend host ports.
2 of the USB1.1 hub ports are available for users.
NOTE: The USB2.0 OTG can be used in host mode or device mode. If you would like to
use it in host mode, a separate OTG-to-host cable is required.
The USB1.1 host connector is a regular USB type A connector that can be connected to
+5V USB storage device. This port is mainly used to connect to USB flash drive.
