Manual Conventions
To help you get the most out of this manual and our products, please note that
we use the following conventions:
Tips are designed to highlight quick ways to get the job done or to reveal
good ideas you might not discover on your own.
NOTE: Notes alert you to important information.
CAUTION! Caution advises you of precautions to take to avoid injury, data loss,
and damage to your boards or a system crash.
Text formatted in bold typeface generally represents text that should be entered
verbatim. For instance, it can represent a command, as in the following
example: “You can instruct users how to run setup using a command such as
setup.exe.”
Bold typeface will also represent field or button names, as in “Click Scan
Network.”
Text formatted in fixed typeface generally represents source code or other text
that should be entered verbatim into the source code, initialization, or other file.
Examples of Manual Conventions
Before plugging any I/O connector into the Cube or RACKtangle, be
sure to remove power from all field wiring. Failure to do so may
cause severe damage to the equipment.
Usage of Terms
Throughout this manual, the term “Cube” refers to either a PowerDNA Cube
product or to a PowerDNR RACKtangle
applicable. The term DNR is a specific reference to the RACKtangle, DNA to the
PowerDNA I/O Cube, and DNx to refer to both.

Introduction
1.2 SL-514 Board Overview
1.2.1 Synchronous
Serial
Interface
The DNx-SL-514 boards are high performance synchronous serial interface
boards.
DNA-SL-514, DNR-SL-514, and DNF-SL-514 boards are compatible with the
Cube, RACKtangle, and FLATRACK chassis respectively. These board versions
are electronically identical and differ only in mounting hardware. The DNA
version is designed to stack in a Cube chassis. The DNR/F versions are
designed to plug into the backplane of a RACK chassis.
SL-514 boards provide four independent channels, each having overvoltage
protection and opto-isolation.
The SL-514 offers four synchronous serial interface (SSI) channels. Each SSI
channel can be programmed independently, and each SSI channel offers a
master and slave port. Each master or slave port can be enabled independently.
1.2.2 Data Rates Supported data rates are between 300 bps to 1.3 Mbps, programmed
independently per channel.
The master output clock is generated with 0.1% or better accuracy.
1.2.3 Data Word
Length
Supported data word lengths are programmable from 3 to 32 bits, programmed
independently per channel.
1.2.4 FIFO Storage Master (receive) data storage is provided via a 2048 word x 32 bit FIFO. Slave
(transmit) data storage is provided via a 1024 word x 32 bit FIFO.
1.2.5 Software
Support
Software included with the DNx-SL-514 provides a comprehensive yet easy to
use API that supports all popular operating systems including Windows, Linux,
real-time operating systems such as QNX, RTX, VxWorks and more.
