2.3 Understanding the COM Functionality

All Kontron COM Express® modules contain two COM Express connectors (X1A and X1B), each with two rows. The
primary connector rows are Row A and Row B (connector X1A). The secondary connector rows are Row C and Row D
(connector X1B). The COMe-cTH6 module uses the PICMG COM Express® pin-out Type 6 definition, which is a recent
addition to the PICMG COM Express standard and documented in Revision 2.0 of the PICMG specification. The Type 6
pin-out is based on Type 2 and also supports new features on the secondary connector. The key changes are:

»

The PCI interface is no longer supported and the pins are used instead for digital display interfaces (DDI) and two
additional PCI Express lanes

»

The IDE (PATA) parallel interface is no longer supported and the pins are used instead for additional transmit and
receive pairs for four USB 3.0 ports.

»

Three dedicated DDI ports have been added. Ports 1, 2, and 3 can be configured individually for Display Port (DP),
HDMI, or DVI and port 1 can also be used for SDV0.

»

Two optional two-wire RS232 serial ports have been added using pins formerly assigned to 12V signals.

The primary connector (Row A and Row B) on the COMe-cTH6 module features the following functionality:

»

Analog VGA graphics

»

Gigabit Ethernet LAN

»

Serial ATA (SATA)

»

PCI Express*

»

USB 2.0 and USB 3.0

»

PCI Express

»

DDI

»

DP/DVI/HDMI

»

LVDS 18/24-bit single/dual channel
