This will show you how to install the mainboard in your HPC laser and get you operational. Have your mainboard (rev2 or rev3) assembled and tested, and download the correct Configuration file for the controller.

There are different types of power supply and different ways to hook up the stepper motors and limit switches:

Both power supplies have a 3-pin cable with a Phoenix connector to connect to the LaOS board.

There are two (known) versions:
31
* one with a JST connector for the X-axis stepper motor and for the limit switches
32
* one with a 12-pin flatcable combining X-axis stepper motor and limit switches

The combination *new power supply* with *flat cable* is described on the [[HPC LS3020 connections - July 2012]] page.

h2. LCD Display
39
40
If you have a LCD display module([[LAOS_I2C_Panel_v03]]), you can laser a new front-plate and install the display
41
Connect the 4 wires of I2C bus from the main board to the display (1:1 connection for rev2 boards). You can
42
use a header, screw terminals, [[JST]] or another connector type.

h2. Ethernet networking
51
52
The LAOS board needs to be hooked up to your Ethernet network. The protocol used is TFTP, which requires either the [[LAOS CUPS driver]] or [[Visicut]] on your computer to talk to it.
53
54
There is a "net.dhcp" configuration parameter in the [[LAOS configuration file]] on the mbed, which causes the LAOS board to obtain an IP address via DHCP if set to "1". The default config file causes the LAOS board to listen on port 69 ("net.port 69").
55
56
If you don't want to use DHCP, you'll need to manually set a couple of network parameters in that same config file.
