COM3~COM 10(CN6 and CN7): The Winbond W83627UHG
Super I/O chipset is connected to the LEC-3100 system
through the LPC bus interfaced to the ICH7M The Super I/O
chipset provides 6 COM ports- two DB-9 male connectors
and 4 by terminal blocks The Fintek F81216AD chipset is
also connected to the system through the LPC bus and
provides the addition of 4 COM ports Together they make
a total of 10 COM ports
IDE Drive Connector (J13): This 2x22 Pin IDE connector
carries the Primary IDE port signals from the ICH7M chipset
This port can be used for connection of two drives (Ultra
ATA 33/66/100 IDE Hard Disks with transferring rate of 33
MB/s, 66 MB/s and 88 9 MB/s respectively are supported )
If two hard disks are connected, one has to be configured
as Master and the other would be Slave, daisy-chained on
a single 44-pin ribbon cable Since the motherboard’s CF
socket (CN4) also connects in parallel to this set of signals,
the CompactFlash can be configured (via jumper J5) to be
either the Master or Slave IDE device
PCI-104 PCI Connector (J11): The mainboard’s PCI-104 PCI
(J11) expansion bus signals are generated by the ICH-7M,
and are essentially identical in function and signaling to a
normal PC motherboard’s PCI bus except for the physical
connector, which is arranged as four 30-pin rows
Note:
We recommend that you use only Lanner
I/O module with this connector to avoid
incompatibility as some pins have been altered
