1.2 Overview
The LaserLight remote display features a super-bright LED display and non-glare filtered lens for use in a wide variety of
applications. The LaserLight Series are available with a 7-segment, 6-digit display or an eight or 12-character matrix display.
The LaserLight remote display is designed to work with most digital weight indicators, host computers, and peripherals using a
20 mA current loop, RS-232 or RS-485 communications.
The unique IntelliBright™ feature uses a photo sensor to read ambient light and automatically adjusts the LaserLight display
between day and night settings.
The display has seven internal buttons and three external buttons to set various parameters. The external buttons include two
for setting the time and date, and one for the learn sequence. The configuration menu is entered via the setup button and is
displayed on the display board panel for easy configuration of the unit.
This manual provides installation and configuration instructions for the display.
1.2.1 Standard Features
The LaserLight 7-segment remote display is available in 4" or 6" digit sizes and the matrix display is available in 2.5" character
size with 8 or 12 positions. The LaserLight 4-SG remote display comes in a 4" digit size in a 6" enclosure size. Both styles use
an Auto-Learn function which automatically determines the serial settings and data format used by the attached indicator.
Additional standard features include:
• Hold displayed weight (demand input)
• Adjustable daylight/night intensity
• Mirror function (weight only)
• Auto-sensing 115/230 VAC power supply
• Mode and unit legends
• Echo
• Traffic light option (4" digit size only)
• Time and date (4", 4"-SG, 6" only)
Optional Features
Optional features of the LaserLight remote display include:
• Temperature
• Field-installable metal visor for all models
• UL Approved Unit
• Time and date (M-Series, 8 and 12 character)

All labels must be in legible condition. If illegible, replace using the part numbers found within Figure 1-1.
1.3 Annunciators
The 7-segment LaserLight remote display uses a set of four high-intensity LED annunciators (Figure 1-2). The matrix display
uses two positions of the display to display arrows which provide additional information about the value being displayed
(Figure 1-3):
Gross and Net annunciators are lit to indicate whether the displayed weight is a gross or net weight.
•lb, kg annunciators indicate the units associated with the displayed value and represent primary and secondary units
• Red, green circle and green arrow annunciators indicate the traffic light state on the display; Feature applies to only the
LaserLight 4-SG

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.

2.4 Wiring
The LaserLight remote display provides three cord grips located on the underside of the enclosure for cabling, one for the
power cord (supplied) and two for serial communications. The LaserLight remote display is pre-wired. Only the serial
communications cable must be connected. An A/C power cord is also supplied.
Use the following steps to wire the remote display:
The LaserLight remote display has no on/off switch. Before opening the unit, ensure the power cord is
disconnected from the power outlet.
1. Open the display and lower the mounting plate (Section 2.2 on page 5).
Use caution when lowering or raising the mounting plate to ensure the LEDs do not contact the enclosure sides.
2. Loosen the retaining screws located on the front of mounting plate (Figure 2-4). The mounting plate is hinged on a
backplate frame to allow easier access to the AC wiring and the CPU board.
Figure 2-4. Retaining Screw Location
2.4.1 AC Wiring
The LaserLight power supply can run on either 115 or 230 VAC.
The AC wiring is run through the cord grip to a 3-position AC terminal block bracket on the inside of the enclosure. This bracket
can be removed by loosening the two standoffs and lifting it off. It can be lowered and pulled outside of the enclosure to ease
wiring connections.
Figure 2-5. Inside Enclosure Backplate Diagram
Refer to the following table for AC wiring connections.
Ensure a ground wire is attached to the grounding stud located on the enclosure backplate.
