2.4.6 Reset Switch
The reset switch enables a simulated power up reset. It then goes back to normal operation mode. The reset
switch eliminates having to unplug the unit to do a reset. Refer to Figure 2-8 on page 7 for the reset switch
location on the CPU board.
2.4.7 Communicating with Indicators and LEDs
Small LEDs located on the CPU board flash when serial data is received or sent. The transmit indicators flash
when data is being sent out of the port. The receive indicator flashes when the data is received. A steady indicator
on any receive LED reflects a connection with no streaming data. See to Figure 2-9 on page 7 for communication
indicator locations on the CPU board.
2.4.8 Decimal Point (7-Segment Display)
The primary display board has decimal LED’s. These can be changed to commas by moving a jumper located on
the front of the display board shown in Figure 3-2 on page 10.
Ensure that the decimal point/comma jumper is in the proper position on the display board.

10 LaserLight Remote Display Installation & Operation Manual
3.0 Configuration
Once the LaserLight remote display is installed, it may need to be configured if your indicator requires special
settings. This can be done manually and is explained in Section 3.2.
Using Auto-Learn (Section 3.1) simplifies installation by automatically detecting the communications format
and data rate used by the indicator and eliminates the need for configuration.
3.1 Auto-Learn
The LaserLight remote display incorporates a software feature called Auto-Learn. Auto-Learn examines the
serial data stream sent from the attached indicator and attempts to determine the data settings and format used by
the indicator.
Auto-Learn occurs automatically when Port 0 is not locked via software configuration (not locked by default)
(Table 3-5), and the connecting indicator is configured to send continuous (streaming) data. It will also occur
automatically if the currently streamed format changes. LaserLight will Auto-Learn by itself in most cases. Or,
you can force this by pressing the external Auto-Learn button.
Use the following quick steps for Auto-Learn.
1. Open the enclosure per disassembly instructions in Section 2.2 on page 3 and connect the serial
interface.
2. Visually inspect that the Auto-Learn button is connected to J5 on the CPU board (see Figure 3-1 for
plug-in location).
3. Power up the remote display.
4. Momentarily press the Learn button.
5. Use the right and left buttons to shift the displayed data string if the displayed weight is not positioned
with LSD.

Table 3-1 summarizes the functions of each of the main menus and Figure 3-4 illustrates the main menu
selections.
Figure 3-4. LaserLight Main Menu Options
When configuring the indicator attached to the remote display, ensure that the decimal point configuration is
compatible with the remote display. The LaserLight 7-segment remote display allows none, one, or two decimal
places (see Figure 3-2 for jumper positions). The 8- or 12-character matrix displays use one character position for
the decimal point.
Figure 3-5 shows the configuration menu.
Figure 3-5. Configuration Main Menu Choices
Note: With the 8- and 12-character matrix displays some of the labels are not shortened, for example STDSTL in the
7-segment is STAND STILL on the 12-character display.
