Step 4: Attach Peripheral Devices
Overview
After you have installed the components in a chassis, attach peripheral devices to the SCB and
XIO, if present (
Figure 8
on
page 19
.)
The tables that begin on
page 30
indicate the
Pin Signals
for peripheral headers and
connectors.
Always power-off the system and disconnect all power cords from their source before
connecting or disconnecting cables for peripheral devices.
When attaching devices to the EPC-3321, certain considerations must be made:
Device(s)
Consideration
Serial
•
These ports are 9-pin male D-Sub connectors on the I/O panels.
•
One serial device can be attached to each 16550-compatible serial port.
•
These ports provide an RS-232 interface.
•
These devices can only be attached to the SCB or the transition I/O module
Parallel
•
These ports are 25-pin female D-Sub connectors on the I/O panels.
•
The IEEE 1284 port provides a Centronics compatible printer interface.
•
AT-compatible / Bi-directional / EPP / ECP operations are supported.
•
These devices can only be attached to the SCB or the transition I/O module
USB
•
The USB bus will support up to 127 USB devices, which can be attached in a daisy-chain
configuration.
•
This SCB supports two USB controllers; one on the front SCB panel, one on the rear XIO panel.
•
A single USB cable cannot exceed 5 meters (16.4 feet) in length.
•
The 5-pin male shrouded, keyed header on the board surface can connect to the Series “A”
connector on the I/O panel.
•
Software drivers appropriate to the OS will be needed to operate USB devices. RadiSys does not
supply such drivers.
EIDE or
IDE
•
Up to two EIDE or IDE devices can be attached to each EIDE header on the XIO.
•
The BIOS will support up to four EIDE or IDE devices. For more information on IDE operations,
see
page 24
.
SCSI
•
Up to 15 SCSI devices can be attached to the XIO on a 68-pin (Ultra Fast/Wide) connector.
•
Up to 15 SCSI devices can be attached to the XIO on a 50-pin (Ultra Fast/Narrow) header.
•
SCSI devices must be connected in a daisy-chain configuration with proper termination.
•
Only one of the three SCSI connectors can be used at any one time.
Floppy
Up to two floppy drives can be attached to the XIO Floppy Disk Drive (FDD) header.
PS/2
Devices
•
A PS/2 mouse and/or keyboard can be attached to the corresponding 6-pin female mini-DIN
connectors on the front or rear I/O panels.
•
These devices can only be attached to the SCB or the transition I/O module
VGA
•
The video connectors on the front and rear I/O panels are 15-pin D-Sub female type.
•
A standard VGA or SVGA interface is provided.
•
Two display devices can be attached to the SCB and XIO at the same time, but video intensity will
be slightly reduced for each device.
Ethernet
•
The Ethernet connectors on the front and rear I/O panels are 8-pin RJ-45 type.
•
Two Ethernet connections can be made, but only one will be active; the BIOS will select one.
•
Two LEDs on the SCB I/O panel indicate the status of Ethernet operations:
•
Activity: This LED indicates either data transmit or receive activity. When activity is occurring,
the LED is lit. When activity ceases, the LED will fade.
•
Link Integrity: This LED indicates whether a valid link is established with the Ethernet controller
in either 10 or 100 Mbps. When the link is valid, the LED is lit. When the link has failed or is
invalid, the LED will fade.
Speaker
Pin 1 on the XIO is the +5 V (+) signal; Pin 2 is the Speaker (-) signal.
System
Monitor
•
This 10-pin male, shrouded header on the XIO provides the interface to an I
2
C network.
•
Pin 8 is the Clock signal; Pin 10 is the Data signal.
Modem
•
The modem connector on the XIO is a 4-pin female RJ-11 type.
•
Four LEDs on the rear I/O bracket indicate the status of modem operations:
•
Receive Data (RXD)
•
Transmit Data (TXD)
•
Data Carrier Detected (DCD)
•
Data Terminal Ready (DTR)
All Devices
When using a flat cable to attach a device, the colored trace for Pin 1 on the cable must align with Pin
1 on the header/connector. See
Figure 8
for an example
System
Reset
•
The cable attaches the System Reset Button on the SCB Faceplate to JP1 on the SCB. See
Figure 1
on
page 4
and
Figure 2
on
page 5
.
•
Pin 1 is the Reset signal; Pin 2 is the Ground.
