12 Serial-Communication Interfaces
Kontron User's Guide EPIC/CE 40
COM B to COM D are available through Connectors X15, X16 and X17 (10 pins in line). To have the signals
available on the standard serial interface connectors DSUB9 or DSUB25, an adapter cable is required. A
9-pin DSUB cable is available from Kontron (KAB-DSUB9-3, Part Number 96061-0000-00-0).
Header Pin Signal Name Function In / Out DSUB-25 DSUB-9

Notes
: (*) To protect the external power lines of peripheral devices, make sure that:
-- the wires have the right diameter to withstand the maximum available current
-- the enclosure of the peripheral device fulfils the fire-protecting requirements of
-- IEC/EN 60950.
12.3 RS-485 Connector
You can use Connector X19 (COM D) for RS422/485 purposes.
Header Pin Signal Name Function
1 4 Channel A positive terminal
2 485_1RXD- Channel A negative terminal
3 GND Ground
4 4 Channel B positive terminal
5 485_1TXD-
Channel B negative terminal
The serial port COM D can only be used either as RS232 (Connector X17) or as RS422/RS485 (Connector
X18).
12.4 Configuration
From the BIOS set-up utility, you can set the serial input/output interfaces to enabled, disabled or auto.
The base I/O-addresses 3F8h, 2F8h, 3E8h, or 2E8h can be configured when enabled, as well as the
interrupts IRQ3, IRQ4, IRQ10 and IRQ11. COM D can be set to the RS232 or RS485 interface. Refer to the
I/O Device Configuration submenu in the Appendix B: BIOS Operation chapter for information on
configuration.
