1. INTRODUCTION TO THE 2000S DISPLAY 1.1 Operation The 2000S is a serial input alphanumeric display. It can accept TTL, RS232, RS422, RS485, or Current Loop as serial data types (depending on input module implemented) and displays information on a field of 20 characters. Baud rates of 300, 1200, 2400, 4800 and 9600 are DIP switch selectable, as are protocol parameters of stop bits, data bits and parity.
2. SETTING UP THE DISPLAY FOR YOUR APPLICATION 2.1 How To Change User Configurable Functions All user configurable functions (input/output type, Baud rate, protocol parameters, line terminator, addressing modes) are located on the main logic board of the 2000S. Before removing the top cover of the display case, note the warning below. Warning - Shock Hazard Disconnect power to the display prior to opening the case. Do not reapply power until the case has been reassembled. 2.
2.5 Selecting A Line Terminator Positions 9 & 10 of the PC mounted, 10 position, in-line DIP switch select the line terminator. The line terminator determines when the 2000S will update its display. If no line terminator is chosen (both 9 and 10 off), the display will be in the direct mode, and any valid character transmitted will be immediately displayed. If one or both of the line terminators ( and ) have been chosen, the display will update in a line mode.
3. INTERFACING TO THE DISPLAY 3.1 Reset Reset is internally pulled high and is active low (contact or switch closure to ground). Reset requires a 10 mS minimum duration signal. A reset places the unit in a state equivalent to power up (ready to receive datadisplay showing set conditions). The unit must be reset in order to acknowledge any changed baud rate, protocol, or address setting. 3.
3.4 Display Update Time There is a required time between transmissions over the serial link while the display interprets the previous data and moves it to the display. The 2000S has a minimum time required between transmissions of 5 mS. 3.5 Relay Output The 2000S has a programmable output which can be accessed through the serial link. This output can be used to control external devices such as indicators or alarms.
3.7 Notes On Vacuum Fluorescent Displays Vacuum fluorescent display technology was chosen for this product because of its superior brightness, viewing angle and spectral qualities. The natural color emitted by the display tube is a greenish-blue, peaking at a wavelength of 505 nanometers. The display is filterable to blue, red or yellow by using different labels. If one of these colors is desirable for your application, please consult the factory.
4. WIRING AND SPECIFICATIONS 4.1 Powering The Display The chart below outlines the operating power requirements of the three different size models of the 2000S display. MODEL 2005S 2009S 2015S SIZE OPERATING POWER 5 mm (0.20") 2.3 VA 9 mm (0.35") 3.6 VA 15 mm (0.59") 6.
4.3 Wiring For Units In Panel Mount Case Units in a case use Electrovert 6 & 8 pin detachable terminal strip connectors, (supplied with unit) for power and signal connections. 120 Volt AC - Panel Mount Case RELAY +5 VDC OUT RESET SERIAL IN + SERIAL IN - SER.

4.5 Wiring Units To A Computer All serial output, such as the output from a personal computer, must match the communication standard of the serial input of the display.

We recommend using shielded cable with the shield grounded at the receiver end.
4.7 RS485 Serial Transmission Maximum length of transmission is 4,000 feet. We recommend using a three-wire cable with the shield grounded at the receiver end. Add a 120 Ohm resistor across serial (+) and serial (-) as a line terminator at each end of the transmission line.
Appendix A Mounting Information Housing Option “C” (Panel Mount Case) The fully enclosed panel mount unit can be mounted through the front panel cutout and fastened to the panel with two side clips (provided). An optional gasket provides front panel Nema 12 sealing.
