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 con
figured to send continuous (streaming) data. It will also occur
automatically if the currently stre
amed 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 disa
ssembly instructions in Section 2.2 on page 3 and connect the serial
interface.
2. Visually inspect that the Auto-L
earn 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.
NOTES:
• If you are using an indicator with a Toledo T8142 format, follow steps 1 through 5 and then go to SP IND
in the serial me
nu. Select 1 under special indicators.
• It is recommended to lock Port 0 (see Table 3-5), to eliminate any un-intenti
onal changes from occurring.
3.2 Manual Configuration
To begin configuration, open the enclosure (See Section 2.2 on page 3 for enclosure disassembly instructions), to
access the CPU board (Figure 3-1) and digit display board (Figure 3-2).
