Module Description

Serial Ports

Each of the four serial ports is located on one dedicated IDC header (COM1-4.) The ports either
work in RS232 or RS485 modes

,

selectable in the BIOS (modification required) or with a user

application. Termination resistors for RS485 Mode must be set by a DIPSwitch (SW1 or SW2).

To enable the transmitters of COM1 through COM4 in RS485 mode during sending, set the
RTS# signal to inactive by setting bit 1 to ‘0’ in UART Modem Control Register MCR. This will
result in a high signal at the transmitter data enable pin and enable the transmitter in RS485
mode.

The serial ports are programmable in BIOS setup:

ADVANCED>CHIPSET>SouthBridge Configuration>Serial/Parallel Port Configuration

The following settings for COM1 through COM4 are available in BIOS setup:



Serial Port: enabled / disabled



Base address: 3F8h / 2F8h / 3E8h / 338h / 2E8h / 238h / 328h / 228h / 220



IRQ: 3 / 4 / 5 / 6 / 7 / 9 / 10 / 11 / 12 / 14 / 15



Bits per Second: 2400 / 4800 / 9600 / 19200 / 38400 / 56700 / 115200

The default values are:



COM1 enabled, 3F8h, IRQ4



COM2 enabled, 2F8h, IRQ3



COM3 disabled



COM4 disabled

The maximum supported baud rates are:



0.75 Mbit/s in RS485 high speed mode



115.2 Kbit/s in RS232 mode

The baud rates can be configured by the user application.

Utility COM Ports

The CM1-86DX2 provides some extra connectivity for an LV-TTL-UART interface (COM6.) More
information on COM6 can be found in the User GPIO (X17) section and Analog-In (X21) about
GPIOs, which are shared with COM6. COM6 does not provide a transceiver and only RX and
TX signals are present.

COM Headers: Ports 1, 2, 3, 4 (X2, X3, X4, X5)

Connector type: DC10 pin header 2.54 mm

Adapter cable: Article number 862-0046-10
