The external connectors have ESD protection. RJ-45 connectors are electrically isolated by
Ethernet transformers.

9.3.2 uDOM

A detachable, non-volatile flash memory, USB Disk On Module (uDOM), is used as the
permanent memory for application and service software and to store clinical and platform
settings. The uDOM can hold two versions of the software in different partitions: inactive and
active.

9.3.3 WLAN assembly

The optional IEEE 802.11a/b/g WLAN module enables wireless network communication in the
2.4 and 5.1 GHz frequency bands. The WLAN module connects to the CPU carrier board.
The two internal dual-band antennas are attached to the rear unit assembly. WLAN connection
is activated when the patient monitor is not connected to a wired network through the MC port.
It shares the same MAC address with the wired MC port.

9.3.4 CPU Module

The patient module has an Intel Atom based COM Express CPU module.
The CPU module has the main processor that manages the data processing of the patient
monitor and volatile SDRAM memory for run time code execution and temporary data storage.
The CPU module provides the following interfaces:
•

LVDS (Low Voltage Differential Signaling) interface for the integrated LCD display and
SDVO (Serial Digital Video Out) output to SDVO-DVI transmitter in the CPU Carrier Board.

•

The Ethernet host controller for the Ethernet switch is in the CPU Module.

•

PCIe interface for the Ethernet controller in the CPU carrier board.

•

USB interface for the uDOM, audio codec, touchscreen controller and PUIC controller

•

SDIO interface for the WLAN module.

9.4 Other subsystems

9.4.1 Display subsystem

Display

The patient monitor has an integrated 12.1" active matrix color TFT LCD panel with a LED
backlight unit. It provides wide viewing angle and supports XGA (1024 * 768 pixels) resolution.
The video controller is integrated into the CPU board and it provides LVDS output to the LCD
panel through the display cable. The display cable also supplies the +3.3 V supply voltage to the
LCD panel.

LCD backlight unit

The LCD panel has an integrated, long-life LED backlight unit that is used to illuminate the LCD
display. The LED backlight unit receives the +12 V input voltage from the DC/DC board via
backlight cable. The backlight enable signal and brightness control is received from the CPU
carrier board.
