Serial Port Interfaces
Two fully functional serial ports (COMA and COMB) provide asynchronous serial communications. COMA and
COMB support RS-232 operation modes. They are 16550 high-speed UART compatible and support 16-byte
FIFO buffers for transfer rates from 50 Baud to 115.2 KBaud.
9.1
Connector
COMA is available through the X15000 connector (10 pins) and COMB through the X15001 connector (10
pins). To have the signals available on the standard serial interface connector DSUB9 an adapter cable is
required.
A 9 pin DSUB cable is available from KONTRON (KAB-DSUB9-2, part number 96017-0000-00-0). The fol-
lowing table shows the pinouts for COMA and COMB as well as necessary connections for DSUB adapters.

Note:
1)
To protect the external power lines of peripheral devices make sure that
- the wires have the right diameter to withstand the maximum available current.
- to enclosure of the peripheral device fulfills the fire-protecting conditions of IEC/EN 60950.
