Service Manual
Step 4: Attach Peripheral Devices
Overview
After you have installed the P3000(D)BX2 in the chassis, attach peripheral devices to
the SBC.
Common
When attaching devices to the P3000(D)BX2 (
), certain
considerations must be made:
Always power-off the system and disconnect all power cords from their
source before connecting or disconnecting cables for peripheral devices.
Device(s)
Consideration
SCSI
•
Up to fifteen (15) SCSI devices can be attached to the 68-pin D-Sub female,
latching connector.
•
SCSI devices must be connected in a daisy-chain configuration with proper
termination.
•
LVD and SE modes are supported. For more information, see
Note:
If both LVD and SE devices are connected simultaneously, the SCSI
controller will switch to Single-Ended mode.
EIDE
•
Up to two (2) EIDE or IDE devices can be attached to the 40-pin male
shrouded, latching header.
•
The BIOS will support up to four (4) EIDE or IDE devices.
•
To use 3 or 4 devices, a 2
nd
controller is required. The 2
nd
controller must
be configured to use IRQ15 and I/O ports 170-177h.
IDE & SCSI
Activity LED
•
This header connects the IDE/SCSI device activity LED cable to the SBC.
•
Pin 1 is the anode (+V); Pin 2 is the cathode (-V).
Floppy
Up to two (2) floppy diskette drives can be attached to the header.
USB
•
Up to 127 USB devices can be attached to each of these 4-pin male
shrouded, keyed headers.
•
USB devices must be connected in a daisy-chain configuration.
•
A single USB cable cannot exceed 5 meters (16.4 feet) in length.
•
Software drivers appropriate to the OS will be needed to operate USB
devices. RadiSys does
not
supply such drivers.
Keyboard
•
An AT or PS/2 keyboard can be attached to this 8-pin male shrouded
header with an appropriate cable.
•
The sockets of the RadiSys keyboard cable are numbered in reverse order
when compared to the pins of the SBC keyboard header, e.g.,
Pin 1 on the cable connector goes to Pin 8 on the SBC header.
Temperature
Monitor
•
A temperature monitoring or controlling device can be attached to this 2-pin
male header.
•
Pin 2 is connected to Ground; Pin 1 is the Open-Collector signal that
transitions from the Logic Low to Logic High state when the CPU
temperature goes outside the range prescribed on
•
The signal requires a current-limiting resistor if connected to an LED.
SMBus
•
The SBC can interface with an I
2
C network via this 2-pin male header.
•
Pin 1 is the Data signal; Pin 2 is the Clock signal.
All devices When using a flat cable to attach a device, the "colored trace" for Pin 1 on the
cable must be near Pin 1 on the header/connector.
