2.3.3 RF interference
An EMI filter can be installed on the serial interface cable to eliminate RF interference.
1. Run the serial wires through the EMI filter provided in the parts kit (Table 2-3 on page 11).
2. Loop the serial wires around the EMI filter.
3. Use the provided plastic cable tie to secure the looped wires to the ferrite and the serial cable; this prevents the ferrite
from coming in contact with the CPU board.

2.4 Battery Replacement
The lithium battery (PN 69291) on the CPU board maintains the real-time clock.
To replace the battery:
1. Ensure unit is unplugged from power source.
2. Open unit and place the tip of a finger in the notched area near the battery retaining spring and slide the battery out of
position on the CPU board.
3. Replace with new battery. Ensure the positive side is up and slide the battery under the retaining ring then close the unit.
Risk of explosion if battery is replaced by an incorrect type. Dispose of used batteries according to state and
local regulations.
2.5 LaserLight2 CPU Board (PN 169279)
Port 0, which is connected to the indicator, supports three configurations; 20 mA, RS-232, and RS-422 communications.
Port 1, which is the Echo port, does not support 20 mA but does support RS-232 communications.

2.5.1 20 mA Current Loop
The 20 mA current loop communication is provided on connector J6 of the CPU board (Figure 2-5 on page 9 and
Table 2-2 on page 8).
Make sure to select active or passive switch settings.
2.5.2 RS-232
The RS-232 connection is provided on connector J8 of the CPU board (Figure 2-5 on page 9 and Table 2-2 on page 8).
2.5.3 RS-422
The RS-422 connection is provided on connector J9 of the CPU board (Figure 2-5 on page 9 and Table 2-2 on page 8).
2.5.4 Reset Switch
The reset switch enables a simulated power up reset, eliminating the need to unplug the unit to perform a reset. The unit then
goes back to normal operation mode, see Figure 2-5 on page 9 for the reset switch location on the CPU board.
2.5.5 Communicating with Indicators and LEDs
There are eight small LEDs for RS-232, RS-422, and 20 mA located on the CPU board (above U8 on the CPU board in
Figure 2-5 on page 9) which flash when serial data is received or sent. The transmit indicators flash when data is sent out of the
port, while the receive indicator flashes when data is received. A steady indicator on a receive LED reflects a connection with
no streaming data.
2.5.6 Ambient Light Sensor (PN 177369)
Ambient light sensors are used to detect light or brightness in a manner similar to the human eye. The ambient light sensor is
connected to J14 on the CPU board and adjusts the brightness on the LaserLight2 in daytime or nighttime conditions.
A third setting (DYLVL) is the ambient brightness threshold, at which the display changes from night to day mode and vice
versa. Settings range between 1 and 10 with 1 requiring less intense light to change to day mode and 10 requiring more intense
light to change from night to day mode.
The LaserLight2 defaults to the Night setting if the sensor is absent.
Do not cut the light sensor pins to the same length, as the long pin is used to identify orientation.
To install a light sensor, ensure the pins (long and short) are inserted correctly into the J14 connector. The short pin side has a
flat side to the sensor and must be oriented on the right side of J14.
Flat Side of Sensor
Long Pin Side
Short Pin Side
Figure 2-6. Light Sensor Pin Orientation
Insert into the terminal block and bend pins slightly to ensure the pins are located by the hole in the bottom of the enclosure.

2.5.7 Decimal Point
Ensure the decimal point configuration is compatible with the remote display when configuring the indicator attached to the
LaserLight2. The primary display board has decimal LED’s. These can be changed to commas by moving jumpers JMP1 and
JMP2 (located on the back of the display board) to the right.
Ensure the decimal point/comma jumper is in the proper position on the display board.

3.0 Configuration
This section provides an overview of LaserLight2 Series configuration instructions.
Configuration can be simplified or eliminated with the Auto-Learn feature.
3.1 Auto-Learn
Auto-Learn examines the serial data stream sent from the attached indicator and determines the data settings and format used
by the indicator. Auto-Learn is capable of recognizing several common data formats used in the weighing industry.
For Auto-Learn to work, the data must be sent using one of the supported baud rates in the exact format of one of the
predefined stream data formats. If the format does not exactly match one of the predefined formats then the Catch All
mode must be used (Section 3.2 on page 19).
Auto-Learn is enabled or disabled based on the setting of the Port 0 Lock parameter. If Port 0 Lock is OFF, the LaserLight2
attempts to learn the incoming data every time it is powered up and each time the data stream is paused and restarted. If Port
0 Lock is ON, no Auto-Learn takes place. By default, Port 0 Lock is set to OFF. If Auto-Learn does not start on its own, it can be
initiated using the following steps.
1. Press . The LaserLight2 cycles through baud rates looking for the one being used. If it can identify the baud
rate and read the format, it displays the weight. If it does not find a baud rate, it displays and reverts to using
the last learned baud and stream data format.
2. Once the Auto-Learn sequence is correct, lock the Port 0 configuration menu to save the Auto-Learn settings
(Figure 3-6 on page 24).
If DSPERR displays after the Auto-Learn process then the value being sent is beyond the capabilities of the display.
Example: Too many digits, or too many digits including a minus sign.

3.2 Catch-All Mode
The Catch-All mode attempts to identify only numeric data in the stream format. No unit or mode annunciators are identified.
The display annunciators can be set manually with the parameter SETANN in the serial menu for Port 0 (
Figure 3-6 on page 24
).
• Manually configure the serial port settings then lock Port 0
• Set the special indicator type to 1 in the Port 0 menu
• The data stream must contain a standard end token character for data packets (<cr>, <lf> <ff>, <ETX> and others) as it
only finds the last data number sent in the packet
Examples: Valid - 1234<cr>5678<cr> displays 1234 then 5678
Valid - 1234 5678<cr> displays only 5678
If the least significant digit of the displayed weight is not in the right most character position, the value can be shifted left or right
using to shift the display.
Example: 12345678<cr> displays 345678, but can be positioned to display 123456 or other sets of six digits.
3.3 Setting Time and Date
Time and Date are standard and factory installed on the 4", 6", and 4" SG models.
The Time and Date (when enabled in the configuration menu) is displayed in three-second cycles (along with weight)
when the displayed weight is zero or below.
To set time and date:
1. Go to CONFIG and enable Time and Date under Enable (Figure 3-3 on page 21).
2. Press to enter the time in hours.
3. Press to increment or decrement the hours.
4. Press to set the hours and move to minutes.
5. Press to increment or decrement minutes.
6. Press to set the minutes and move to the month.
7. Repeat steps to set the month, day, and year.

3.8 Demand Print Displaying
The indicator and LaserLight2 remote display can be set up to demand print display.
Demand print display is set up using Auto Learn when the Port 0 Hold Weight parameter is turned on. It can also be set up
manually by configuring the Port 0 parameters of the remote display and indicator.
Using Auto-Learn, ensure HOLD WT is on and continuously push the print button on the indicator to attempt a demand print display.
3.9 Serial Commands
The LaserLight2 has the ability to receive commands, display messages, or use a digital I/O (2 inputs and 2 outputs). When
interfaced to an indicator which has a configurable serial string, the print ticket format can be configured, allowing the user to
press Print on the indicator and send a message which temporarily interrupts the streamed weight display. The length of time
the message displays is defined by the MSG TM (message time) parameter in the CONFIG menu (Figure 3-3 on page 21).
If the LaserLight2 remote display is interfaced with a programmable smart indicator, a user program can be written allowing the
user to send messages utilizing softkeys or events. The user can send one message to temporarily override the streamed
weight display (Learn Enable is ON); or send multiple messages to be displayed one at a time, replacing the weight display
(Learn Enable is OFF and no streamed weight data is available).
The remote display accepts serial commands to return the current time and date or to set the time and date to a new setting.
This information can be used in conjunction with user programs in the indicator and remote display to ensure both have the
same time and date settings.

Note
3.9.2 Set or Get the Digital I/O Dry Contact Wiring
The Dig 0 and Dig 1 pins on the traffic light board (pin 2 and pin 3 on connector J1 respectively) have pull up resistors which
allow operation of the traffic light can be controlled by switching Dig 0 or Dig 1 (or both) to ground.
Pressing the reset button on the LaserLight2 CPU board sets the D0 and D1 pins on the LaserLight2 CPU (pins 5
and 6 on J1) to a high pulled up state, which is the default state of the traffic light to be a stop light (red).
Single Switch Wiring
The user must select two of the four possible states if they want a single switch used for controlling the traffic light.
Two Switch Wiring
It is possible to obtain a variety of combinations of the four possible states using two switches to control the traffic light.
• Both switches with contacts closed give the OFF condition
• Both switches with contacts open give the STOP condition
• One switch open and the other closed gives either the Go or Arrow condition
Signal Digital 1 Signal J1- 6 Digital 0 Signal J1 - 5
Stop Open (H) Open (H)
Arrow Open (H) Closed (L)
Go Closed (L) Open (H)
Off Closed (L) Closed (L)
Table 3-9. Traffic Option Wiring
Connect Digital 1 Example
1. Disconnect wire connecting D1 (pin 6 on J1) of CPU to Digital 1 (pin 3 on J1) of the traffic light pcb at the CPU connector.
2. Solder the wire going to Digital 1 on traffic light board to the wire which goes to the switch.
3. Place wires back into the connector on the CPU board (pin 6 on J1).
4. Connect other end of the switch wire to one pole of the switch.
5. Connect the remaining switch pole to the digital ground of the indicator. If a common ground between the indicator and
the LaserLight2 does not exist (fiber optic communication is used), an additional wire is needed for connecting the
switch to the ground on the LaserLight2 CPU board.
This connection does not harm the CPU board since digital outputs on CPU board are designed to be pulled low.
The digital outputs are set to High (OFF) on reset.
To use the two Digital Inputs and Digital Outputs, use J1 to connect and use the following message command formats to set or
get the Digital I/O (Figure 2-5 on page 9).
