1 Introduction
Figure 1 MPX-24794S USB-Serial Card
MPX-24794S Serial USB Card provides SPI master interface, I2C master interface, a
16-bit general purpose counter, and 16-bit GPIO interfaces via USB 2.0 full speed
device connection. This card is in Mini-PCIe form factor and is using only the USB
signaling portion of the standard Mini-PCIe interface.
This card is powered by a Cypress CY8C24794 micro-controller with 24 MHz system
clock frequency. The USB is compliant to USB 2.0 full speed device. This card
provides you a convenience way to connect your systems to those SPI slave devices,
I2C slave devices, and devices that need GPIO interface. A 16-bit general counter
with Enable pin input is also provided. A compare true pin out and terminal count pin
out are also provided.
2.54mm pitch test pins are come with this card for your easy usage.
Device drivers for Microsoft Windows 2000, Windows XP (32-bit and 64-bit),
Windows Vista (32-bit and 64-bit), and Windows 7 (32-bit and 64-bit) are supplied in
the product CD.

connect a MPX-24749S card to the target PC.
2.3.1 Via Mini-PCIe Slot
You can simply connect a MPX-24749S card to the target PC via inserting a MPX24749S card into a standard Mini-PCIe slot. This is because a standard Mini-PCIe
slot provides USB signals in its interface. Commell motherboards that feature MiniPCIe slot(s) are compliant to industrial standard Mini-PCIe slot interface and
therefore are good for MPX-24794S card. Please check your target board user's
manual.
The following figure shows how to insert a MPX-24749S card into a standard MiniPCIe slot of a motherboard.

2.3.3 Via OALUSB-H4 Cable (Option)
Third way to connect a MPX-24749S card to your target PC is via OALUSB-H4
cable. This cable connects a MPX-24794S card to the target PC through USB pin
header. Please check the user's manual of your motherboard to locate a right USB pin
header.
The following figure shows how the OALUSB-H4 cable is connecting a MPX24749S card to a target PC.

2.4 Optional GPIO Signal Isolation Boards
In the real practical situations, cases are connecting signal isolation boards to MPX24794S cards before connecting to those input and /or output devices. Both ADPGPIO4I4O5V and ADP-GPION8I5V boards are designed for this purpose.
MPX-24794S card provides a convenient way to connect to the ADP-GPION4I4O5V
and ADP-GPION8I5V signal isolation boards. The OAL-24794S-ADP cable is
designed specially to connect to these two boards.
2.4.1 ADP-GPION4I4O5V (option)
ADP-GPION-4I4O5V is a signaling isolation board for Commell GPIO products.
This board has four photo-couple input connectors and four relay output connectors.
Four photo-couple diodes protect input lines from the damage caused by ElectroStatic
Discharge (ESD) and other transients. Four relays feature high current contacts
capability.

Use either P1 and/or P2 connector (2x6 header) of OAL-24794S-ADP cable to
connect to one or two of this board.
2.4.2 ADP-GPION8I5V (option)
ADP-GPION8I5V is a signaling isolation board for Commell GPIO products. This
board has eight photo-couple input connectors. Eight photo-couple diodes protect
input lines from the damage caused by ElectroStatic Discharge (ESD) and other
transients.
