Introduction
This manual provides detailed hardware information on the eNet2-1553 interface 
product.
In addition to this information, the reader may also want to reference the following 
documents provided on the CD and our Web Site
• AltaCore™ Specifications and User Manual: Detailed description of the 1553 
protocol engine of the card. Most people do not need this detail and will mainly 
reference the AltaAPI manual for their application development.
• AltaAPI™ User’s Manual: Detailed description of the application program 
interface (API) and device drivers of this software package. 
• AltaView™ User’s Manual: AltaView is the latest 1553 analyzer on the market 
and this manual details the usage of the product.
• AltaRTVal™ User’s Manual: This manual details the usage of AltaRTVal, which 
is an automated program to run AS4111/4112 RT Validation and Production Test 
Plans.
• 1553 Tutorial and Reference, and 1553B Standard. These documents provide a 
detailed review of the 1553 standard, which is required for proper usage of this 
product. SEE THIS DOCUMENT FOR WIRE & CABLING INFORMATION OF 
1553 BUSSES – THIS IS REQUIRED FOR PROPER BUS OPERATIONS.

ESD and General Handling of Computer Interface Cards
The Alta warranty requires that the product be handled with proper ESD controls. The 
JEDEC standard on ESD handling, JESD625-A, is available for free download at 
. Please follow the standard’s guideline for proper ESD handling 
methods. At a minimum the following guidelines should be followed:
• Avoid carpets in cool, dry areas. 
• Leave the card in its anti-static packaging until ready to be 
installed. 
• Dissipate static electricity before handling the card by touching a 
grounded metal object, such as the metal chassis of the system 
(the system should be plugged-in, but turned-off). • Use antistatic devices, such as wrist straps and floor mats.
• Always hold the card by its edges. Avoid touching the 
components or connectors. • Be sure to align card edge or assembly cable connector pins
before installation. Misaligned connectors can cause damage to 
the card or system, especially at power-on.
• Take care when connecting or disconnecting cables. When 
disconnecting a cable, always pull on the cable connector, not 
on the cable itself. 
eNet2-1553 Description
eNet2-1553 is an innovative product that provides “remoting” of 1553 operations on 
10/100/1000 Ethernet IP/UDP local area networks (LAN). eNet2-1553 is a small, low￾power, rugged device that provides connectivity for up to two dual redundant 1553 bus 
and is ideal for remoting 1553 connections for in-field applications or point-point lab 
usage.
Alta has combined the industry’s most advanced 32-bit 1553 FPGA protocol engine, 
AltaCore™, with a real-time IP/UDP thin server. The customer can implement their 
application with the same feature-rich application programming interface, AltaAPI™, 
which is a multi-layer ANSI C and  2.0 (MSVS 2005/2008 C++, C#, VB 
.NET) architecture. This hardware and software package provides increased system 
performance and reduces integration time.
