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.

Please note:
The flash and microSD disk have a finite number of program-erase cycles.
Important information should always be backed up on other media or storage device for
long-term safekeeping.
The Li-batterie can continually supply power to the 512 KB SRAM to retain the data for 10
years (It is recommended that batteries are changed each 5~7 year.)

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.

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.

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.

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.

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.

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.

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.
