SERIAL PORTS CONNECTORS (J4)
Two serial ports are provided on the board. They are 16C550 compatible and support 16-byte
FIFO buffers. Serial Port 1 is buffered for RS-232 operations, while Serial Port 2 may be set
for RS-232 or RS-422/RS-485.
The J4 connector is a dual Serial Port connector that provides two communication ports
configured as COM1 and COM2. Both act as DTE.
For information on the programming of serial ports with the use of FIFO buffers, ask for
Application Note # AN93007 from TEKNOR’s Technical Support department.
