1.2.1 Tokens

The Laser LT has tokens that can be used in the general formatting of a serial string. The Laser LT will light the status annunicators (tokens) based on the ASCII characters sent in the serial string. Those tokens are:

• Gross Character

• Net Character

• P rimary Character

• Secondary Character

• Negative Character

• Overload Character

• Center of Zero Character

• M otion Character

These tokens and their function are explained i

WARNING

CAUTION

Four keyhole slots (only two shown)

Two latches secure the lid of the Laser LT

The Laser LT remote display can be easily set up and configured. This section describes basic installation, AC wiring, RS-232 and 20mA current loop connections. Once installation setup is complete, go to Section 3.0 for information on configuring the Laser LT.

Use a wrist strap to ground yourself and protect components from electrostatic discharge (ESD) when working inside the enclosure.

The

Laser LT has no on/off switch. Before opening the unit, ensure the power cord is disconnected from

the power outlet.

2.1 Unpacking and Assembly

Immediately after unpacking, visually inspect the Laser LT remote display for damage. If any parts were damaged in shipment, notify Rice Lake Weighing Systems and the shipper immediately. The shipping carton contains the remote display, a parts kit, and this manual. Parts kits contents are listed in Table 6-5 on page 35.

2.2 Wall Mounting

The Laser LT remote display can be mounted to any vertical surface. Select a site for installing the Laser

installation screws or wall anchors to secure the remote display to a wall.

NOTE: Install lockwashers ﬁrst, against enclosure, under grounding clamp

The Laser LT remote display provides two cord grips located on the underside of the enclosure for cabling; one for inputs, and one for outputs. An AC power cord is supplied with the unit. Only the serial communications cable must be connected. Use the following steps to wire the remote display.

The Laser LT remote display has no on/off switch. Before opening the unit, ensure the power cord is disconnected from the power outlet.

Open the remote display by unlatching the lid (shown in Figure 2-2).

2.3.1 Cable Grounding

Except for the power cord, all cables routed through the cord grips shou ld be grounded against the Laser LT enclosure. Do the following to ground shielded cables:

• Use the lockwashers, clamps, and kep nuts provided in the parts kit to install gro enclosure studs adjacent to cord grips. Install grounding clamps only for cord grips that will be used; do not tighten nuts.

• Route cables through cord grips and grounding clamps to determi

ne cable lengths required to reach cable

connectors. Mark cables to remove insulation and shield as described below:

• For cables with foil shielding, strip insulation and foil from the grounding clamp (see Figure 2-3). Fold the foil shield back on the c

2.3.4 Serial Wiring

Serial communications are connected to the CPU board using clamp spring connectors on J2, J3 and J4 (see Table 2-3 for wiring positions ).

To connect the communications

1. If the enclosure is not open, make sure power is disconnecte

cable to the remote display, do the following:

d from the unit and open the latches on the

enclosure.

2. Loosen the serial cable cord grip an

d push enough communications cable into the enclosure to allow

attachment to the CPU board.

3. Strip 1/4" (.65 cm) of insulation from the serial cable ends.

4. Make cable connections for RS-232, or 20 mA current loop communications. Communications can be ma

de to any port. Com options are set up on ports 3 and 4. See Configuration of ports (host, keypad, daisy

chain) in Table 3-3 on page 19.

5. Remove any excess cable from inside the enclosure. T

ighten the serial cable cord grip.

The maximum cable lengths that can be used for various communications types depend on a number of factors. These include: output impendance of the transmitter, electrical noise in the environment; cable capacitance, gauge, termination, and shielding.

Given that these and other factors will af

as a general guide for the Laser LT communications cabling.
