1. Introduction

This chapter introduces the fundamental concepts for the user with the LinPAC AM335x series.

LinPAC AM335x series is the new generation Linux-based PAC (Programmable Automation

Controller) from ICP DAS and is equipped with a Cortex-A8 CPU (1.0 GHz) running a Linux kernel

3.x operation system, multiple communication interfaces and slots for high performance parallel

I/O modules and serial I/O modules.

Main advantage of the LinPAC AM335x PAC is its high quality control system, including its stably

properties, open source and the standard LinPAC SDK for Windows and Linux using the GNU C

language, JAVA and GUI software. The main purpose of LinPAC AM335x PAC is to allow the

numerous enthusiastic Linux users to control their own embedded system easily within the Linux

environment.

ICP DAS also provides a library file, libi8k.a, custom applications can easily be developed for the

LinPAC AM335x PAC using either C or Java and .NET applications will also be supported in the

future. The various functions contained in the library are divided into sub-group functions for ease

of use within the different applications.

2. LinPAC AM335x Getting Started

This chapter provides a guided tour of the LinPAC AM335x series PAC installation and

configuration that describes the steps needed to download, install, configure, and run the basic

procedures for the user working with the in LinPAC AM335x PAC for the first time.

2.1. Mounting the Hardware

2.1.1. Mounting the LP-22xx

DIN-Rail mounting

The LP-2241 has simple rail clips for mounting reliably on a standard 35 mm DIN-Rail.

AM335X-PAC Series User Manual version 2.0.1 Page: 10

2.1.2. Mounting the LP-52xx

DIN-Rail mounting

The LP-5231 has simple rail clips for mounting reliably on a standard 35 mm DIN-Rail.

AM335X-PAC Series User Manual version 2.0.1 Page: 11

Remove the LP-5231 from the DIN-Rail

Wall/Panel mounting

The LP-5231M/LP-5231PM-3GWA/LP-5231PM-4GE/LP-5231PM-4GC can be mounted either

directly to a wall/panel.

Step 1: Install the four mounting screws into

the 4 keyhole mounting holes.

Step 2: Fasten the screws securely.

AM335X-PAC Series User Manual version 2.0.1 Page: 12

2.1.3. Mounting the LP-8x2x

Wall/Panel mounting

The LP-8x2x can be mounted either directly to a wall/panel or onto a standard 35mm DIN-Rail.

Step 1: Install the four mounting screws

into the 4 keyhole mounting

holes.

Step 2: Fasten the screws securely.

Tips & Warnings

There must be a minimum clearance of 50mm between the LP-8x2x and the top

and bottom side of the enclosure panel.

AM335X-PAC Series User Manual version 2.0.1 Page: 13

DIN-Rail mounting

Step 1: Hook upper tab over upper flange of DIN-Rail.

Step 2: Tilt the module toward DIN-Rail until it snaps securely to DIN-Rail.

AM335X-PAC Series User Manual version 2.0.1 Page: 14

Tips & Warnings

A good common ground reference (earth ground) is essential for proper

operation of the LP-8x2x. One side of all control circuits, power circuits, and the

ground lead must be properly connected to earth ground by either installing a

ground rod in close proximity to the enclosure or by connecting to the incoming

power system ground. There must be a single-point ground (i.e. copper bus bar)

for all devices in the enclosure that require an earth ground.

AM335X-PAC Series User Manual version 2.0.1 Page: 15

2.1.4. Mounting the LP-9x2x

Wall/Panel mounting

The LP-9x2x can be mounted either directly to a wall/panel, or onto a stainless 35mm DIN-Rail.

Step 1: Install the four mounting

screws into the 4 keyhole

mounting holes.

Step 2: Fasten the screws securely.

Tips & Warnings

There must be a minimum clearance of 50 mm between the LP-9x2x and the top

and bottom side of the enclosure panel.

AM335X-PAC Series User Manual version 2.0.1 Page: 16

Step 3: Connect the ground lead to

the frame ground point.

Tips & Warnings

A good common ground reference (earth ground) is essential for proper

operation of the LP-9x2x. One side of all control circuits, power circuits, and the

ground lead must be properly connected to earth ground by either installing a

ground rod in close proximity to the enclosure or by connecting to the incoming

power system ground. There must be a single-point ground (i.e. copper bus bar)

for all devices in the enclosure that require an earth ground.

DIN-Rail mounting

Step 1: Fasten the DIN-Rail clip to the LP-9x2x.

AM335X-PAC Series User Manual version 2.0.1 Page: 17

Step 2: Clip the device onto a stainless DIN-Rail.

Tips & Warnings

For DIN-Rail mounting, it is strongly recommended that only a stainless steel

DIN-Rail be used to support the weight of the LP-9x2x system, providing stability

and preventing LP-9x2x from leaning.

AM335X-PAC Series User Manual version 2.0.1 Page: 18

Step 3: Connect the ground lead to the frame ground point.

Tips & Warnings

A good common ground reference (earth ground) is essential for proper

operation of the LP-9x2x. One side of all control circuits, power circuits, and the

ground lead must be properly connected to earth ground by either installing a

ground rod in close proximity to the enclosure or by connecting to the incoming

power system ground. There must be a single-point ground (i.e. copper bus bar)

for all devices in the enclosure that require an earth ground.

2.1.4.1. Installing the RJ-45 waterproof connector assembly

The LP-9x2x series is equipped with an RJ-45 waterproof connector to withstand contaminant in

the dusty environment.

The RJ-45 waterproof connector is optional for use with LAN1 port. If you do not need the RJ-45

waterproof connector, you can remove the cap and just plug in a regular Ethernet cable.

If you want to use the RJ-45 waterproof connector for protecting the connection, follow the

instructions below.

Step 1: Remove the RJ-45 connector from the RJ-45 cable.

Step 2: Feed the end of the RJ-45 cable through the (A) sealing nut, (B) rubber sealing insert, (C)

clamping ring, (D) cable gland base and (E) panel gasket.

AM335X-PAC Series User Manual version 2.0.1 Page: 20

Step 3: Wrap the (E) panel gasket base around the (D) cable gland base.

Step 4: Wrap the (C) clamping ring around the (D) cable gland base.

Step 5: Insert the (B) rubber sealing insert into the (D) cable gland base.

AM335X-PAC Series User Manual version 2.0.1 Page: 21

Step 6: Push the (A) sealing nut forward and Hand-tighten it to seal the assembly.

Step 7: Insert the RJ-45 cable into the RJ-45 connector.

Step 8: Push the RJ-45 waterproof connector assembly forward.

Step 9: Insert the Ethernet cable and screw the RJ‐45 waterproof into the receptacle.

AM335X-PAC Series User Manual version 2.0.1 Page: 22

2.2. Deploying a Basic System

The LinPAC AM335x series PAC provides a variety of communication interface to suit a range of

application. Here is a simple application for using the LP-22xx/52xx/8x2x/9x2x.

Tips & Warnings

1. The input range of power supply is +10 V

to +30 VDC for LP-8x2x/9x2x

DC

and +12 VDC to +48 VDC for LP-22xx/52xx.

2. The LP-8x2x/9x2x have two power inputs that can be connected

simultaneously to the two independent power sources. If one power

source fails, the other source takes over automatically. Redundant power

input help assure non-stop operation of the LP-8x2x/9x2x.
