2.2 Enclosure Disassembly
For ease of installation, remove the mounting plate (which includes the primary and secondary display boards)
before installing the
enclosure lighter for installation. Use the following steps to remove the mounting plate from the enclosure.
1. Remove the captive screws located on the bottom of the enclosure. The mounting plate is located on the
inside of the enclosure. It is mounted on a frame that can be held in place by tabs and two pins, (located
on the inside of the enclosure, shown in Figure 2-2).

2.3 Wall Mounting
The LaserLight remote display can be mounted to any vertical surface or pole.
Select a site and use installation screws or wall anchors to secure
the remote display to a wall. If installing the
remote display on a pole, an optional pole mounting kit is required, this kit fits 4" - 8" poles. Once the enclosure
is secured, slide the mounting plate down so that it is hanging 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 (cord supplied), and two for serial communications. The

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 (shown in Figure 2-4). This bracket can be
removed by loosening the two standoffs
and lifting it off. It can then be lowered and pulled outside of the
enclosure to ease wiring connections.
Figure 2-4. Inside Enclosure Backplate Diagram
Wiring is run from the terminal block down to the power supply on the back of the mounting plate (location
shown in Figure 2-5).
Figure 2-5. Mounting Plate Diagram with CPU Board and Power Supply Locations
NOTE: Pin 1 is positioned at the left end of the connectors. See Figure 2-5 above.
Refer to the following table for AC wiring connections.
Note: Ensure that a ground wire is attached to the grounding stud located on the enclosure backplate (see Figure 2-4).

3. Loosen the serial cable cord grip and push enough communications cable into the enclosure to allow
attachment to the CPU board.
4. Strip 1/4" (.65 cm) of insulation from the serial cable ends.
5. Make cable connections for RS-232, RS-485, or 20 mA cu rrent loop communications as described in
Table 2-2.
6. Remove any excess cable from inside the enclosure. T

1. Loop the serial wires through the cylindrical ferrite (PN 66730) provided with this manual. See
Figure 2-7 below.
2. Using the plastic cable ties provided,
secure the wires to the ferrite and the serial cable to the learn switch
wires to keep ferrite from contacting the CPU board. See Figure 2-7 below.

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.
2.4.3 20 mA Current Loop
The 20 mA current loop communication is provided on connector J6 of the CPU board (Figure 2-8,Table 2-2).
Ensure receive jumpers are across RX0, 20 mA and select
active or passive switch settings. Remove any unused
jumpers. (Figure 2-9)

2.4.6 Reset Switch
The reset switch enables a simulated power up reset. It then goes back to normal operation mode. The reset
switch eliminates having to unplug the unit to do a reset. Refer to Figure 2-8 on page 7 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 any receive LED reflects a connection with no streaming data. See to Figure 2-9 on page 7 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 shown in Figure 3-2 on page 10.
Ensure that 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 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
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
(Table 3-5), and the connecting indicator is con
