9.2.6 External interfaces

M-Ports
Four M-Ports are provided on the front of the CPU unit for connecting the PRN50 and Unity ID.
Basic insulation (250 VAC) is provided to isolate the CPU unit from M-Port devices. Each M-Port
supports the 1-Wire, Serial (RS-232) and Ethernet Protocols. Each M-Port can supply 100mA at
4.75V minimum.
The connector used for the M-Ports is an 8-pin, RJ-45 type.
eT-Ports
The connector used for the eT-Ports is a DB-9 Female.
ePort Devices
Ethernet connections
Two Ethernet ports are located on the back of the CPU unit and they provide an ANSI/IEEE
802.3 10/100 BaseT Ethernet standard interface to the CARESCAPE Network/ S5 network and
Hospital Enterprise network. Basic insulation (250 VAC) is provided to isolate the CPU unit from
networked devices.
The connector used for the Ethernet ports is a dual 8-pin, RJ-45 type.
Video Outputs
A DVI-I and a DVI-D ports are located on the back of the CPU unit. An optional 3rd Video Card
(2020913-003) provides an additional interface to analog and digital displays.
Each DVI-I & DVI-D port has the following features:
• DDC (Data Display Channel) support
• Resolution of 1024 x 768 x 60HZ.
DVI-I can drive displays in the following configurations:
• Digital only, using DVI-D to DVI-D cable
• Analog only using DVI-A or VGA cable
• Both digital and analog, using the Y-split cable along with a DVI-D to DVI-D cable and a
DVI-A to VGA Cable. Note in this configuration image on both the analog and digital
display will be the same with same resolution i.e., 1024x768 @ 60Hz.
DVI-D can drive displays in the following configuration:
• Digital only, using DVI-D to DVI-D cable
Serial port
Two RS-232C compatible serial ports are located on the back of the CPU unit to provide an
interface to serial touchscreens.
The connector used for the serial ports is a DB-9M.
USB 2.0
Four USB ports are located on the back of the CPU unit to provide an interface for a USB based
Remote Control Assembly, keyboard, mouse, Bar Code reader, a touch screen display, or PC
interface.
