Quick Start
Before using the ASEK, Allegro recommends that you read and understand this entire document.
However, in most cases, basic configuration can be done very quickly so that you can start to
familiarize yourself with the ASEK. The basic steps are described in this section. The configura-
tions described are for operating the ASEK in a direct connection to a personal computer that has
an Internet Web browser installed.
To set up the ASEK, perform the following steps:
1
Connect the ASEK Main Board module to the computer using either a standard Ethernet
crossover cable, or a separately-powered Ethernet hub and two standard Ethernet LAN cables
(the computer may be powered-on at any time).

Solder the device-under-test (DUT) socket to the appropriate ASEK interface board, and
connect the ribbon cable between the interface board and the ASEK Main Board module
(Figure QS-2). (DUT connection without interface board is described later in this document.)

CAUTION: ONLY USE the power supply included in the ASEK. Select a regional power plug
appropriate for the test facility, and swap it into the transformer body.Then connect the mini
plug to the ASEK module and connect the wall plug to the facility power mains.(Figure QS-3)
The ASEK powers-on immediately. Allow 30 seconds for the firmware to load.

Open the Internet Web browser on the computer, and navigate to http://192.1.2.3. The ASEK
software opens as a Web page.
Insert the DUT into the socket and use the ASEK software to perform demonstrations.
