2.0 Installation/Setup
The LaserLight remote display can be set up and configured once it is mounted. This section describes basic installation,
AC wiring, RS-232, RS-485 and 20 mA current loop connections. Once installation setup is complete, see Section 3.0 on
page 11 for information on configuring the remote display.
The LaserLight has no on/off switch. Before opening the unit, ensure the power cord is disconnected from the
power outlet.
Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working
inside the enclosure.
This unit uses double pole/neutral fusing which could create an electric shock hazard. Procedures requiring
work inside the remote display must be performed by qualified service personnel only.
2.1 Unpacking and Assembly
Immediately after unpacking, visually inspect the LaserLight remote display for damage. If parts were damaged in shipment,
notify Rice Lake Weighing Systems and the shipper immediately. The main components of the LaserLight remote display
include:
• Powder coated steel or stainless steel enclosure
• Primary and secondary display boards
• Power supply
• Mounting panel for the CPU board (located on back of mounting plate)
Remove the protective plastic on the lens of the LaserLight as it obscures the display over time and becomes
very difficult to remove later on.

2.2 Enclosure Disassembly
For ease of installation, remove the mounting plate (which includes the primary and secondary display boards) before installing
the LaserLight remote display. This protects the LEDs from unnecessary jarring and makes the enclosure lighter for installation.
Use the following steps to remove the mounting plate from the enclosure.
Use caution when lowering/raising the mounting plate to ensure LEDs do not contact the enclosure sides.
1. Remove the captive screws located on the bottom of the enclosure. The mounting plate is located on the inside of the
enclosure, on a frame which can be held in place by tabs and two pins (Figure 2-2).
2. Glide the mounting plate frame downward, allowing it to hang freely beneath the enclosure.
3. Disconnect the chassis ground wire from the top of the mounting plate mounting frame.
4. Disconnect the AC cord assembly from the power supply.
5. Using a slight diagonal twisting motion, slide the mounting plate out from the inside of the enclosure and set it aside.
Figure 2-2. Tab Pin Assembly on Inside of Remote Display Enclosure
2.3 Wall Mounting
The LaserLight remote display can be mounted to vertical surfaces or a pole.
Select a site and use installation screws or wall anchors to secure the remote display to a wall using the mounting holes on the
flange tabs. The flange hole size accommodates 1/4" hardware.
Figure 2-3. Mounting Flange 4'' LED Remote Display
An optional pole mounting kit, which fits 4" - 8" poles, must be used when installing a remote display on a pole (Section 4.4 on
page 25).
Once the enclosure is secured, slide the mounting plate down to allow it to hang freely from the enclosure with the tabs secured
against the pins. This enables the user to continue wiring the remote display.

LaserLight Remote Display CPU Board
Port 0 which is connected to the indicator supports three configurations: 20 mA, RS-232, and RS-485 communications.
Port 1 which is the Echo port, supports 20 mA and RS-232 communications.
Figure 2-9. LaserLight Remote Display CPU Board
2.4.3 20 mA Current Loop
20 mA current loop communication is provided on connector J6 of the CPU board (Figure 2-9 and Table 2-2 on page 8).
Ensure receive jumpers are across RX0, 20 mA and select active or passive switch settings. Remove unused jumpers
(Figure 2-10).
2.4.4 RS-232
The RS-232 connection is provided on connector J8 of the CPU board (Figure 2-9 and Table 2-2 on page 8).
Ensure transmit and receive jumpers are across TX0 232 and RX0 232 (Figure 2-10).
2.4.5 RS-485
The RS-485 connection is provided on connector J9 of the CPU board (Figure 2-9 and Table 2-2 on page 8).
Ensure transmit and receive jumpers are across TX0 485 and RX0 485 (Figure 2-10).

2.4.6 Reset Switch
The reset switch enables a simulated power up reset. It goes back to normal operation mode. The reset switch eliminates
having to unplug the unit to do a reset, see Figure 2-10 on page 9 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 receive LEDs reflect a
connection with no streaming data, see Figure 2-10 on page 9 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 (Figure 3-2 on page 12).
Ensure the decimal point/comma jumper is in the proper position on the display board.

3.0 Configuration
Once the LaserLight remote display is installed, it may need to be configured if the indicator requires special settings.
Configuration can be done manually and is explained in Section 3.2.
Using Auto-Learn simplifies installation by automatically detecting the communications format and data rate used by the
indicator and eliminates the need for configuration, see Section 3.1 for an overview of Auto-Learn.
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) and the connecting
indicator is configured to send continuous (streaming) data (Table 3-5 on page 17). It also occurs automatically if the currently
streamed format changes. LaserLight Auto-Learns by itself in most cases. This process can be forced 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 5 and connect the serial interface.
2. Visually inspect to ensure 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.
If using an indicator with a Toledo T8142 format, follow Step 1–Step 5 then go to SP IND in the serial menu. Select 1
under special indicators.
It is recommended to lock Port 0 to eliminate un-intentional changes from occurring (Table 3-5 on page 17).
3.2 Manual Configuration
To begin configuration, open the enclosure, see Section 2.2 on page 5 for enclosure disassembly instructions, to access the
CPU board (Figure 3-1 and Figure 3-2 on page 12).

Table 3-1 summarizes the functions of each of the main menus and Figure 3-5 illustrates the main menu selections.
When configuring the indicator attached to the remote display, ensure 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 on page 12
for jumper positions. The 8- or 12-character matrix displays use of one character position for the decimal point.
Figure 3-5. Configuration Main Menu Choices
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.
