Page 7: Annunciators
Annunciators The Laser LT remote display uses a set of six designated LED annunciators (shown in Figure 1-3) and a red and green (stop/go feature lights). The annunicators are dependent on the status character. They can also be associated with ASCII characters (tokens) and are shown in Table 4-1 on page 25 and the default status characters are shown in Table 3-2 on page 14. -
Page 8: Tokens
1.3.1 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: •... -
Page 9: Installation And Setup
Installation and Setup 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 CAUTION working inside the enclosure. -
Page 10: Wiring
Wiring 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. -
Page 11: Ac Wiring
2.3.2 AC Wiring The Laser LT AC power cord comes in through a cord grip to the AC to DC power supply. The DC then goes to J5 on the main CPU board (see Table 2-3 on page 9). Power Supply Figure 2-4. -
Page 12: Dc Wiring
2.3.3 DC Wiring Alternatively a 9-36V DC power converter may be supplied. To connect DC power to the DC to DC converter, wire the positive voltage to pin 1 (red wire - right hand side of connector), ground to pin 3 (black wire-left side) on CN1 DC power supply . -
Page 13: Serial Wiring
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 cable to the remote display, do the following: 1. If the enclosure is not open, make sure power is disconnected from the unit and open the latches on the enclosure. -
Page 14: Reset Switch
Communications Cable Distance Limitations The maximum cable lengths that can be used for various communications types depend on a number of factors. These include: output impedance of the transmitter, electrical noise in the environment; cable capacitance, gauge, termination, and shielding. Given that these and other factors will affect the maximum usable cable length, the following distances can be used as a general guide for the Laser LT communications cabling. -

Page 16: Configuration
Configuration Once the Laser LT remote display is installed, it may need to be configured. This can be done manually through the front panel and is explained in Sections 3.2 through 3.6. Using Auto-Learn (Section 3.1) simplifies installation by automatically detecting the communications format and data rate used by the indicator and may eliminate the need for configuration. -
