2.4.6 Ambient Light Sensor (177369) Ambient light sensors are used to detect light or brightness in a manner similar to the human eye. The ambient light sensor is located on the CPU board and adjusts the brightness on the LaserLight2 in daytime or night time conditions. The LaserLight2 defaults to the Night setting if the sensor is absent. Do not attempt to cut the light sensor pins to the same length. To install a light sensor, ensure that the pins (long and short) are properly 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. Figure 2-6. Light Sensor Pin Orientation Insert into the terminal block and bend pins slightly so that the pins are located by the hole located in the bottom of the enclosure. 2.4.7 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 that the decimal point/comma jumper is in the proper position on the display board. Figure 2-7.

3.0 Configuration This section explains how to manually configure the indicator for necessary or required special settings. Configuration can be simplified or even 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. The default setting for Auto-Learn is On and it will automatically occur through Port 0 if not locked. 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 will show the weight. If it does not find a baud rate, it will show  2. Once the Auto-Learn sequence is correct, lock the Port 0 configuration menu to save the Auto-Learn settings (Figure 3-4 on page 20). If DSPERR displays after the Auto-Learn process, the value being sent to the display is beyond the displays capabilities. 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 will be identified. The display annunciators can be set manually with the parameter SETANN in the serial menu for Port 0 (Figure 3-4 on page 20). • Manually configure the serial port settings and 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 the data packets (ie: , , ) as it will only find the last data number sent in the packet. Examples: Valid - 12345678 displays 1234 and then 5678 Valid - 1234 5678 displays the 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 displays 345678 but can be positioned to show 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 display (when enabled in the configuration menu) shows in three-second cycles (along with weight) when the displayed weight is zero or below. Use the following steps to set time and date on the LaserLight2. 1. Go to CONFIG and enable the Time and Date under Enable. See Figure 3-3 on page 18. 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. LEARN Note Note SET MODE SET

6. Press to set the minutes and move to the month. 7. Repeat steps to set the month, day and year. 3.4 Manual Configuration Use the following steps to begin configuration. 1. Open the enclosure. See Section 2.3 on page 6 for enclosure disassembly instructions. 2. Press on the front panel overlay to access the main menu configuration parameters. Main menu parameters include: • Configuration • Serial communications • Test • Version The LaserLight2 remote display can be configured using a series of menus accessed using the keys shown in Figure 3-1. 3. Use to navigate through menu items and for setting a selection. When the External Keypad is Disabled There may be instances where the external keypad needs to be disabled. To disable the external keypad: 1. Open the enclosure (Section 2.3 on page 6) for enclosure disassembly instructions. 2. Move the setup jumper (circled in Figure 3-1), to pin positions 2 and 3. 3. Press located on the CPU board to enter into configuration mode Once the external keypad is disabled, proceed to configuration. Figure 3-1.

3.7 Version The current software version displays on the remote display. Figure 3-6. Version Menu 3.8 Demand Print Displaying The indicator and the LaserLight2 remote display can be set up to demand print display. Demand print display 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 the 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 & 2 outputs). When interfaced to an indicator having a configurable serial string, the print ticket format can be configured to allow the user to press Print on the indicator and send a message that 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 18). 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; or send multiple messages to be displayed one at a time, replacing the weight display. 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. Figure 3-7.

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 so the operation of the traffic light can be controlled by switching the Dig 0 or Dig 1 (or both) to ground. Pressing the reset button on the Laserlight CPU board sets the D0 and D1 pins on the Laserlight 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 wish to see a single switch is used for controlling the traffic light. Two Switch Wiring It is possible to obtain any or all 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 and, one switch open and the other closed gives either the Go or Arrow condition. Connect Digital 1 Example 1. Disconnect the wire connecting D1 (pin 6 on J1) of the 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 the traffic light board to the wire that will go to the switch. 3. Place the wires back into the connector on the CPU board (pin 6 on J1). 4. Connect the 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. 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 (ie: 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 the digital outputs on the CPU board are designed to be pulled low. The digital outputs are set to High (OFF) on reset. Table 3-10.
