Purpose of this Guide
This guide contains technical and product-related information on the SST-DN3-104-1
and SST-DN3-104-2 network interface cards.
The SST-DN3-104-1 consists of a single DeviceNet network interface (or channel), and the
SST-DN3-104-2 comprises two independent interfaces, controlled by independent CPUs.
Each CPU executes downloadable application firmware modules, which enable application-level
product behavior. For more details, refer to relevant firmware documentation.
Note
An application running on one channel does not affect the performance
of other channels, as it does not share memory or processor resources
with them.
Note
In this manual, the SST-DN3-104-1 and SST-DN3-104-2 will be
referred to as the card, except where product differences apply.
Using this Guide
If you are running a 3rd party application or writing your own application using the card’s DLL
calls, the sections of interest in this guide will be “Card Overview”, “Installation” and potentially
“Troubleshooting”. If you are writing your own application in a non-Windows environment
(interfacing directly with the card’s memory registers), we recommend that you read the whole
guide.

1.1 Warnings and Cautions
The card is an electrical component and must be treated with the following precautions:
Warning
Only qualified electrical personnel familiar with the construction/
operation of this equipment and the hazards involved should install,
adjust, operate, and/or service this equipment. Read and understand this
guide in its entirety before proceeding. Failure to observe this precaution
could result in severe bodily injury or, in extreme cases, loss of life.
Warning
You must provide an external, hard-wired emergency stop circuit
outside the programmable controller circuitry. This circuit must disable
the system in case of improper operation. Uncontrolled machine motion
may result if this procedure is not followed. Failure to observe this
precaution could result in bodily injury.
Caution
The card contains static-sensitive components. Careless handling may
severely damage the card. Do not touch any of the connectors or pins on
the card. When not in use, the card should be stored in an anti-static bag.
Failure to observe this precaution could result in damage to or
destruction of the equipment.

1.2 Card Features
The card is a PC/104 interface for communication with DeviceNet and other CAN-based
networks. The main features of each channel are:
• 16-bit PC/104 interface (compliant with PC/104, specification 2.4). 16 bits is the width
of the data bus and does not restrict the card from being used in a 32-bit operating
system.
• 66 MHz ColdFire Processor
• 256 KB of shared RAM
• DeviceNet-compliant 5-pin CAN connector
• Data rate of up to 1 Mbaud for CAN, and 125K, 250K and 500K for DeviceNet
• Bi-color LEDs showing card status
• Isolated physical layer
1.3 Byte Ordering
The card uses Intel-style (little endian) byte ordering for multi-byte entities LSB-low address and
MSB-high address. If your host system uses Motorola (big endian) byte ordering (MSB-low
address and LSB-high address), you must compensate for byte ordering in software.
The following language macro will compensate for byte ordering in a 16-bit data entity:
#define SWAP_WORD (WordData) ((WordData<<8) | (WordData>>8))
1.4 DN3 Compatibility
For a comparison of DN3 with DNP, refer to Section D.2, Reference Documents.

1.5.1 CAN Connector
The 5-pin connector is a removable connector that conforms to the standard DeviceNet pinout.
Pin numbers, names and color codes are identified in the figure below.

1.5.1.1 V+, V-
These terminals provide power to the isolated section of the network interface, and
must be connected and powered for the card to communicate on the network. On DeviceNet
networks, they connect directly to the red (V+) and black (V-) wires of the DeviceNet cable.
On non-powered CAN networks, they must be connected to an external 24VDC supply.

Use, duplication or disclosure of this document or any of the information contained herein is subject to the restrictions on page ii of this document.
1.5.1.2 CANH, CANL
These are the CAN communication bus signal terminals. Use only shielded twisted pair cable.
When using the card on DeviceNet with DeviceNet approved cabling, these wires will already be
a twisted pair with the proper DeviceNet impedance.
1.5.1.3 SHIELD
This is the shield connector. This terminal is “snubbed” to the PC/104 chassis ground via a
1M-ohm resistor, through the PC/104 standoffs connected to holes H1 and H2.
Note
The shield should be connected directly to earth ground at only one
point in the network.

1.5.2 LEDs
There are three LEDs per channel: Power (PWR), Health (HLTH) and Communications
(COMM).
Note
For information on troubleshooting using LEDs, refer to Section 4.1,
HLTH or PWR LED is Red.
1.5.2.1 PWR LED
The PWR LED is an indicator that represents whether or not power is applied to the
CAN connector. The PWR LED’s behavior is described in the following table:

1.5.2.2 HLTH LED
The HLTH LED indicates the channel’s health status. The HLTH LED’s behavior is described in
the following table:
Table 3: HLTH LED Behavior
Color Status
Off Card initialization failed or the card is not powered
Green The firmware is running
Red The card has halted or there is a firmware run-time error
Amber Startup self-test complete, no firmware loaded. The
firmware must be reloaded (refer to Section 4.1,
HEALTH or PWR LED is Red).
Note
If the HLTH LED is flashing, there may have been a startup failure.
For more details, refer to Section A.3, Fatal Hardware Self-Test Flash
Codes.
1.5.2.3 COMM LED
The COMM LED indicates the network status. This LED’s meaning and behavior are
determined by the currently loaded firmware module. Refer to the module’s reference guide for
more details.
