Step 2: Disconnect Power

Disconnect LaserLight3 power cable from power outlet.

Step 3: Open Enclosure

Open the LaserLight3 enclosure.

❗ IMPORTANT: The ConnexLink power cable has a black (negative) wire and a black with white segments (positive) wire. Ensure power cables wires are connected to the power supply terminals with the same polarity.

Step 4: Connect Negative Power Wire

Attach the black negative power wire's spade to the free -V0 terminal on LaserLight3 power supply.

Step 5: Connect Positive Power Wire

Attach the black and white positive power wire's spade to the free +V0 terminal on LaserLight3 power supply.

Step 14: Clean Mount Surface

Clean mount surface with Isopropyl Alcohol, and let dry.

Step 15: Position and Attach ConnexLink

Peel protective backing off adhesive standoffs and position ConnexLink with power jack at top (vertically) in left side of LaserLight3 enclosure.

❗ IMPORTANT: Ensure ConnexLink position will not obstruct enclosure door operation or make contact with circuit boards.

Apply firm pressure to adhesive pads for 30 seconds.

Serial Configuration

After hardware installation, LaserLight3 software must be configured to communicate from its RS-232 port with the ConnexLink. In order to function correctly, the Baud and Bits parameters in the LaserLight3 require setup.

? By default LaserLight3 is configured with the required parameters to operate the ConnexLink. Ensure that the following settings are configured. If LaserLight3 default serial communication configuration has been altered, the system will not function. For more information about LaserLight3, see LaserLight3 Large-Display Weight Indicator Technical Manual (PN 213589) or LaserLight3 Remote Display Technical Manual (PN 214748).

Figure 13. Baud/Bits Parameter Menu Path

Two diagrams illustrating the menu navigation paths on the LaserLight3 for configuring serial communication parameters like Baud, Bits, and Stop Bits, for both the Large-Display Weight Indicator and the Remote Display models.

Step 1: Enable Setup Mode

Enable Setup mode by either pressing the MENU key (if a shunt is installed on J24 pins two and three) or opening the LaserLight3 and shorting J25 pins momentarily.

? Enabling Setup mode grants access to various LaserLight3 menus that are restricted in normal operation, including the Setup menu.
