AKAREL7

The “AKAREL” is the heart of the BATM, and is itself composed of several discrete components.

This guide describes the AKAREL7, which is used on some models of the BATMTwo.

ALWAYS unplug your BATM before attempting disassembly or installation.

Overview

AKAREL7 Mainboard

The Illuminator and the Acceptor DB9 cables attached:

The fingerprint scanner and QR scanner attached:

CPU/Coreboard

Check for proper seating of the CPU coreboard.
The metal edges of the contacts should be even and barely visible.
The coreboard is connected and held in-place by the two clips.

When installing the core, listen for the click:

WiFi Antenna

The WiFi antenna is attached to the door, facing outwards, covered by the GB label. The other end is a U.FL micro-coax cable fitting and it simply presses onto the socket located on the coreboard.

REMOVAL: Gently lift the WiFi cable connection up & off with a screwdriver.
ATTACHMENT: orient the fitting over the socket and press gently down. The cable should be oriented as shown for proper seating.

LCD display connectors:

The LVDS (Low-Voltage Differential Signaling) cable provides the screen details (pixel control).

Possible symptoms of malfunction include: scrambled video, lines in video, missing colors.

The backlight cable provides power to the display panel.

A typical symptom of malfunction is no video (a “dead screen”).

For the technically adept, the other ends of these 2 cables connect to the LED display panel.

DISASSEMBLY MAY VOID YOUR WARRANTY. PROCEED AT YOUR OWN RISK.

Touchscreen

The AKAREL7 has 2 types of touchscreen connection, and the cable will use only one (of the two possible types).

Type 1

The cable is loosened (for removal) by gently pulling up on the tension bar. The tension bar (or seat) does not normally pull up/out completely. It is not designed to come off or come apart.

The ribbon cable must be fully inserted before reseating the tension bar during installation.
Only the very tips of the copper contacts are visible when the ribbon is properly inserted.

Shipping the AKAREL7 for service:

1. Remove the USB, power, DB9, and WiFi cables.

The attached DB9 cable (#5) services an MEI/ CPI acceptor. Two thumbscrews hold the DB9 connector in place (turn counter-clockwise to loosen). They should be only hand-tight (no tools required) - but on occasion they may require pliers to initially loosen them.
