Step 4: Attach Peripherals to Headers
Overview
After you have installed the EPC-2102 onto a passive backplane in a chassis, attach the
necessary peripheral devices to the appropriate headers on the SBC (
Figure 6 ).
SCSI Drive
Up to fifteen SCSI devices can be attached to this header via a 68-conductor flat cable in a
daisy-chain configuration.
Note: The "red stripe" on the cable should be near Pin 1 on the header.
EIDE Drive
Two EIDE (backwards-compatible with IDE) hard disk drives can be attached to this header
via a 40-conductor flat cable.
Note: The "red stripe" on the cable should be near Pin 1 on the header.
IDE/SCSI
Activity LED
This header connects the IDE or SCSI drive activity LED cable to the SBC.
Note: Pin 1 is the anode; Pin 2 is the cathode.
FDD
Two floppy disk drives can be attached to this header via a 34-conductor flat cable.
Note:
The "red stripe" on the cable should be near Pin 1 on the header.
Serial Port 2
A serial device can be attached to this header (16550-compatible) via a 10-conductor flat
cable. If connecting a serial mouse, be sure to use a shielded cable.
Note: The "red stripe" on the cable should be near Pin 1 on the header.
USB Ports
A 4-conductor USB cable can be attached to each of these headers. See page 30 for pinouts.
Note:
Software drivers appropriate to the OS will be needed to operate USB devices.
RadiSys does not supply such drivers.
Mouse
A PS/2 mouse can be attached to this header via a 10-pin (2x5) cable adapter.
The BIOS will support up to four IDE drives. To use 3 or 4 drives, a 2 nd controller is
required. The 2
nd
controller must be configured to use IRQ15 and I/O Ports 170-177h.
!
Improperly connecting the cable to this header can cause damage to the
cable, SBC, and external serial device, and could void the warranty.
