Chapter 5  Input/Output Interfaces

 

 
 

5.4 SERIAL 

INTERFACE

 

 
All models include at least one RS-232-C type serial interface to transmit and receive 
asynchronous serial data with external devices. The serial interface function is provided by the 
LPC47B367 I/O controller component that includes two NS16C550-compatible UARTs.   

 

The UART supports the standard baud rates up through 115200, and also special high speed rates 
of 239400 and 460800 baud. The baud rate of the UART is typically set to match the capability of 
the connected device. While most baud rates may be set at runtime,

 baud rates 230400 and 

460800 must be set during the configuration phase. 

 

5.4.1 SERIAL CONNECTOR

 

 
The serial interface uses a DB-9 connector as shown in the following figure with the pinout listed 
in Table 5-5.

The standard RS-232-C limitation of 50 feet (or less) of cable between the DTE (computer) and 
DCE (modem) should be followed to minimize transmission errors. Higher baud rates may require 
shorter cables.
