OPERATION

The following are the normal operational steps for using the MONTEST-LCD.

1. Connect the monitor to the MONTEST-LCD. See the section on "CONNECTIONS" (page 2) for details.

2. Turn ON the MONTEST-LCD power. The MONTEST-LCD can be used with the AC adapter, or the internal batteries.

3. Use the GROUP button to select the group of scan formats to be used. See the tables under SCAN FORMATS (pages 8 and

9), as required.

4. Use the NEXT and PREVIOUS buttons to step through the scan formats until the desired scan format is found.

5. The ALT button can be used to look at the additional screens of LCD data. Also the pixel time, sync type, and sync polarity
can be reviewed or changed.

6. Once the desired scan format is displayed, pushing the SELECT button will turn ON the video and sync outputs. The raster
icon will then be displayed on the LCD and the raster video pattern is output to your monitor.

7. Change the pattern, colors, and intensity as desired.

8. Pushing the SELECT button again will turn OFF the video and sync outputs. Also changing the scan format with GROUP,

NEXT or PREVIOUS will turn OFF the video and sync outputs.

CHANGING BATTERIES

The MONTEST-LCD can be powered by 6 alkaline C-size batteries. To change the batteries, follow these steps:

1. Normal electrostatic discharge (ESD) handling precautions should be observed when the enclosure of the MONTEST-LCD is
open. Touch a grounded surface before performing any hardware procedure.

2. Turn OFF the power and remove all connections to the MONTEST-LCD.

3. Place the MONTEST-LCD upside down on a work surface.

4. Remove the 2 Phillips head screws that hold the top and bottom of the enclosure together.

5. Carefully turn the MONTEST-LCD right side up, holding the enclosure together.

6. Lift off the top of the enclosure to expose the battery holder.

7. Install 6 new alkaline C-size batteries noting the battery polarity marked on the battery holder.

8. Reverse this procedure to reassemble the MONTEST-LCD.

Note: Dead batteries should be removed from the MONTEST-LCD to prevent damage caused by acid leaking from a
battery.

Introduction

The VPI MONTEST-LCD has a 2.1x5.5 mm male, center positive jack. The MONTEST-LCD can accept power from either 6 "C"
size batteries or an AC adapter. To use an AC adapter, one with the following specifications must be purchased::

• output voltage from 9 to 15 VDC

• output current of 500 ma

• 2.1x5.5 mm female plug with positive center

If an AC adapter that meets these specifications cannot be found, VPI has provided a 2.1x5.5 mm female plug that can be used to
replace the tip of another AC adapter that you have purchased.

WARNING! YOU MUST FOLLOW THESE INSTRUCTIONS CAREFULLY! REVERSING THE POLARITY OF THE AC
ADAPTER BY ATTACHING THE POSITIVE AND NEGATIVE WIRES TO THE WRONG TABS WILL CAUSE PERMANANT
DAMAGE TO YOUR VPI SWITCH. VPI is not responsible for units damaged due to polarity reversal, which will void your
Warranty. If you purchased an adapter with a 2.1x5.5mm female plug – make sure the PLUG CENTER is POSITIVE.

Plug Installation

1. Cut the small adapter plug off of the end of your AC adapter.

2. Unscrew the plastic housing from the VPI supplied 2.1x5.5mm female plug and slide it over the wire on the end of the adapter
(see Fig 1).

3. Strip the wires back about 1/8”.

4. Using a voltmeter, determine which wire is positive and which is negative. Label the wires to ensure they do not get crossed.

5. Solder the positive wire to TAB “A” per Fig 2. Solder the negative wire to TAB “B”.

6. Squeeze the strain relief tabs on TAB “B” (see Fig 2) around the two wires. Make sure they are as tight as possible since
they will prevent the solder connections from being pulled apart.

7. Slide the plastic housing up to the plug and screw it on.

Using a voltmeter, plug the adapter in and verify that the voltage reads POSITIVE (+) on the CENTER.
