2.4.2 Serial Wiring
Serial communications are connected to the CPU board using removable screw terminal plugs on J6, J8 and J9
( Figure 2-9 on page 9 ).
To connect the communications cable to 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 ).
2. Remove the captive retaining screws and flip forward the hinged mounting plate.

3. Loosen the serial cable cord grip and push enough communications cable into the enclosure to allow attachment to
the CPU board.
4. Strip serial cable jacket back to cord grip (metal construction) location to expose the braided shield. Trim the braid,
shield wire or foil back to within 1" (1.5 cm) of stripped cable jacket ( Figure 2-7 ).
5. Feed the cable through the dome nut and clamping insert. Fold the braided shield over the clamping insert, making
sure the braided shield overlaps the O-ring by 3/32" (0.2 cm).
6. Push the clamping insert into the body and tighten the dome nut.
7. Make cable connections for RS-232, RS-485, or 20 mA current loop communications.
8. Tighten the serial cable cord grip.
