4 Simplex Multiplexer TECHNICAL OVERVIEW Video Input and Output The Simplex system features video camera inputs with a passive looping output for each. Synchronizing or phasing cameras is not required. The Simplex comes with a main monitor output for displaying live camera images or recorded images on a standard monitor. The call monitor output permits viewing live images from a selected camera on a standard monitor.
Chapter 1 — About Simplex Encoder Output 5 The Simplex video encoder produces a single video signal containing field by field samples from all camera inputs. The signal is provided in composite format for connection to a video recorder. All inputs are sampled in camera number order until motion is detected; then sampling is weighted in favor of the cameras where activity is detected. The encoder uses Vertical Interval Signaling (VIS) technology to encode system information onto video output to the VCR.
6 Simplex Multiplexer Chapter 2 — Front and Rear Panels Figure 4 — Front Panel Controls and Indicators THE FRONT PANEL The following is a brief overview of the front panel. Refer to Chapter 4 — Setup and Chapter 5 — Operation for details on features and panel functions. Some front panel buttons have two functions. The primary button function is listed first, followed by the secondary function in parentheses. Indicator lights (LEDs) are above each button. 1.

Chapter 3 — Installation 9 Chapter 3 — Installation Select a location for the product that is clean and dry and has AC power. Find an environment where temperature and humidity extremes do not exceed the product specification (see Appendix D — Technical Specifications). Failure to do so can result in equipment failure and/or loss of warranty protection. REQUIRED CONNECTIONS Cameras Connect the cam in BNC connector to the video output of a camera or other composite video source.
10 Simplex Multiplexer Alarm The alarms connector includes pins for mechanical or TTL/CMOS standard alarm inputs, the alarm hold input and the alarm output. These connections allow the Simplex to be completely integrated with security systems. See Chapter 6 — Alarms and Appendix A — Alarm Connector Pin Assignments for details. Alarm Inputs Alarm Inputs may consist of a contact type or TTL/CMOS alarm signal.
Chapter 3 — Installation 11 SYSTEM CHECKOUT You can check Simplex system operation immediately after installation. While the Simplex itself requires no adjustment, check system components such as monitors, cameras and the video recorder for proper operation and adjustment. The system checkout procedure involves three steps: monitor calibration, camera check and video recorder check. You need at least two video cameras to check system operation. Make certain that all required system connections are made.
12 Simplex Multiplexer Camera Check The multicamera display in live mode makes checking camera performance as simple as comparing two pictures on one screen. This method is preferable to the direct camera to monitor technique because it allows precise adjustment of each camera against a chosen reference camera. This minimizes differences between cameras and optimizes picture quality. NOTE: Before performing a camera check, complete the monitor calibration procedure.
Chapter 3 — Installation Making a Test Tape 13 The easiest way to verify system operation is to make a test recording and play it back. This process effectively tests every piece of equipment in the system. Before proceeding with recording, we recommend that you complete both the monitor calibration and camera check procedures. Make certain that the monitor and all system cameras are correctly adjusted. This will ensure better results during the test. The procedure is as follows: 1.
14 Simplex Multiplexer Chapter 4 — Setup THE SETUP MENU SYSTEM Simplex features can be configured to suit the requirements of most video installations.
Chapter 4 — Setup 15 SETUP MENUS The following paragraphs take you through the menu system step-by-step, describing each menu’s purpose and options. System Time/Date This menu displays the time and date stored in the internal clock/calendar, firmware version number and revision date. During normal operation, the Simplex displays the time and date at the top of the screen and encodes time and date onto each field of video sent to the VCR. During tape playback the encoded time and date is displayed.
16 Simplex Multiplexer Toggle Options The toggle options menu allows you to review and set each option. Toggle options have only two values. To change a value, position the highlight over it and press the up or down arrow. The other value appears. Toggle options include: Alarm Message Display The ALARM MESSAGE DISPLAY option lets you control whether an ALARM message displays on-screen. It toggles as follows: ON — Alarm messages are displayed on the main monitor.
Chapter 4 — Setup Alarm Input Polarity 17 The ALARM INPUT POLARITY option allows you to set the polarity of all alarm inputs. It toggles as follows: ACT LOW — Active alarm inputs are “low.” The Simplex recognizes a contact closure or TTL/CMOS logic low as an alarm event. ACT HI — Active alarm inputs are “high.” The Simplex recognizes a contact opening or TTL/CMOS logic high as an alarm event. The default ALARM INPUT POLARITY setting is ACT LOW.
18 Simplex Multiplexer Quad Record Option (four-camera models only) This option allows you to record quad images rather than the default full screen image recording. The quad image must be displayed to record in quad mode. ON — With quad displayed, records the quad image. OFF — Will NOT record a quad image, or display quad in record mode, only full-screen images sent in record mode. The default QUAD RECORD OPTION is OFF.
Chapter 4 — Setup VCR Alarm Record Time 19 This menu allows you to set the recording speed of the VCR when an alarm is triggered (1–999 hours). The VCR changes to this speed when alarm input is received. NOTE: If you connect pin 37 on the Simplex alarms connector to the VCR, you don’t need to set VCR RECORD TIME or VCR ALARM RECORD TIME. If your VCR provides a timing signal (it may be called vcr trigger input, sync pulse input or clock) connect pin 37 on the Simplex alarms connector to the VCR.
20 Simplex Multiplexer Global Dwell The GLOBAL DWELL menu allows you to set the camera switching rate. The GLOBAL DWELL setting determines the rate at which the cameras are sequenced full screen when sequence (up arrow) is selected. It also determines the rate the monitor switches cameras during multiple alarms. Set the GLOBAL DWELL time in seconds using the up and down arrow buttons. You may enter any setting between 1 and 99 seconds. This setting applies to all cameras.
Chapter 4 — Setup Motion Setup 21 The motion setup screen allows you to define motion detection targets in the camera’s field of view. This screen is accessed from the Camera Titles menu by pressing the FUNCTION button. The motion setup screen displays the current camera image overlaid with a special graphic. The graphic consists of a 16 wide by 12 high matrix of motion targets, a target cursor, and a motion bar. The target cursor (a horizontal line) is initially positioned in the first row of targets.
22 Simplex Multiplexer LIVE — turns ON the row of targets with the cursor line. TAPE — turns OFF the row of targets with the cursor line. CAMERA — toggles the corresponding target on the cursor line. FUNCTION — saves the current motion target settings and returns to Camera Titles. Use the buttons above to define areas of the picture in which motion is to be detected. When finished, press the FUNCTION button to save the target settings and return to Camera Titles.
Chapter 5 — Operation 23 Chapter 5 — Operation OPERATING MODES The Simplex has three basic operating modes: record, live without record and tape playback. Record mode is the only mode which sends camera images to the VCR and includes motion (activity) detection. Live mode displays cameras without recording the images. Tape playback mode is strictly for viewing a previously recorded tape. Record Mode Press RECORD to start sending images to the VCR.
24 Simplex Multiplexer Record mode is the only mode affected by the motion detection feature. Images are sent to tape more often from cameras where activity is detected when motion targets are ON. In one camera recording mode, an encoded full-screen image from the selected camera is output to the VCR at the programmed time-lapse rate. If REC ALL displays, press FUNCTION and a CAMERA button to start recording just one camera.
Chapter 5 — Operation 25 Live Mode Without Record Live mode is used for viewing a multicamera image on the main monitor. No recording takes place while in live mode. The LIVE LED is lit. The on-screen record status message (if set ON in the Setup menu) flashes REC OFF. The RECORD and TAPE LEDs are off. Pressing the LIVE button displays the images from multiple cameras.
26 Simplex Multiplexer Tape Playback Mode Main monitor display: Pressing TAPE puts the unit in playback mode to review a previously recorded tape. You can press a display format button (2x2, 3x3 or 4x4) to see a multicamera display, or you can even customize the display by pressing and holding either the 2x2, 3x3 or 4x4 button and pressing CAMERA buttons in the order you want them displayed. Pressing a CAMERA button shows the selected camera image from tape displayed full-screen.
Chapter 5 — Operation 27 For optimum tape recording or playback, the Simplex should be correctly set up for use with the VCR. This is done by changing settings in the setup menu system. Two setup options affect camera recording. They are: VCR RECORD TIME VCR ALARM RECORD TIME See Chapter 4 — Setup: VCR Record Time and VCR Alarm Record Time.
28 Simplex Multiplexer One Camera Recording The Simplex can be set to record just one camera. This feature can be turned on or off at any time. If one camera recording is turned on, the FUNCTION LED flashes, the RECORD LED is on and the status message 1 CAM=XX shows on the main monitor (XX represents the camera number). NOTE: When the FUNCTION LED is flashing, only the selected camera is recorded. You must press the RECORD button to resume recording all cameras.
Chapter 5 — Operation 29 NOTE: For quad recordings, if you use time-lapse or pause mode during playback, images may look blocky with just one field displayed. If you press and hold the FUNCTION button, you can see both fields displayed. You will get better results with a 2-hour playback speed. VCR Special Effects Most special video playback features can be used while reviewing a recording.
30 Simplex Multiplexer Chapter 6 — Alarms The Simplex system detects and responds to three types of alarm events: mechanical alarms, recorded alarms and video loss. A mechanical alarm event occurs when there is a contact closure at any alarm input. A recorded alarm event occurs when an alarm encoded field is detected during tape playback. A video loss alarm occurs when the Simplex system detects loss of video at an active camera input.
Chapter 6 — Alarms Alarm Counter 31 The Simplex counts the number of mechanical alarm events that occur at each camera input. It maintains a total count for each camera until the alarm counter is cleared. The maximum alarm count per camera is 999. Once the counter reaches 999, it does not change until it is cleared. To Display the Alarm Counter Screen: Press FUNCTION+left arrow. The Simplex displays the alarm count for each camera input and the time/date when the count was last cleared.
32 Simplex Multiplexer Record Mode Alarm Response When a mechanical alarm occurs in record mode, the Simplex alerts the operator and performs tasks required to record the alarm event on videotape. When the initial alarm is detected in record mode: 1. The associated CAMERA LED flashes. 2. The alarm relay is energized. 3. The monitors display a full-screen image of the camera associated with the alarm. With multiple alarms, full-screen images sequence at the current dwell rate on both monitors. 4.
Chapter 6 — Alarms 33 Tape Playback Mode Alarm Response When the Simplex system is in tape playback mode, only the call monitor responds to live alarm events by displaying the associated camera. The Simplex sends nothing to the VCR, does not display graphic messages, and does not flash the LEDs. RECORDED ALARMS The Simplex must be in tape playback mode to display and process recorded alarms. The Simplex detects recorded alarm events by monitoring the VIS information returned from tape.
34 Simplex Multiplexer Chapter 7 — Special Applications The features and flexibility of the Simplex make it a powerful tool in special applications where unique capabilities are required. This section describes several ways to use the Simplex. MULTIPLEXED VIDEO TRANSMISSION Two Simplex systems can be employed to transmit video from multiple cameras over a single video communication link. The link may be coaxial cable, a microwave channel, or other mediums that support real-time video.
Chapter 7 — Special Applications 35 REMOTE CONTROL The Simplex provides two methods of remote control, a Remote Control Panel option, or using an ASCII terminal or computer to send RS-232 data. Both methods use the rear panel remote in and remote out connectors. Remote Control Panel A Remote Control Panel option is available for the Simplex. It consists of a front panel assembly, a desktop stand, rack mount brackets, and a 50 foot cable.
36 Simplex Multiplexer APPENDIX A ALARM CONNECTOR PIN ASSIGNMENTS The alarms connector is a DB37-S. It accepts a DB37-P mating connector. Connect ground wires to the gnd screw (next to the alarms connector).
Appendices APPENDIX B ALARM RECORDING CONTROL 37 Most installations require that alarm events be documented on videotape. The Simplex provides all of the necessary connectors and signals to accomplish this. The Simplex is compatible with virtually all VCRs and flexible enough to satisfy most video documentation requirements. An alarm event begins when an active alarm signal is detected at the alarms connector.
38 Controlled Alarm Recording Simplex Multiplexer When alarm recording is controlled by the Simplex, the VCR records cameras with alarm signals as alarm video. The recorder responds to the alarm signal provided by the Simplex system. It enters the alarm recording mode and changes to the alarm record speed. The VCR remains in the alarm mode until released by the Simplex. Controlled alarm recording requires both video connections and alarm connections between the Simplex and the VCR.
Appendices APPENDIX C IN CASE OF TROUBLE 39 If a problem occurs, review the section of the manual which covers the activity associated with the problem. If necessary, consult the Troubleshooting Guide on the following pages. If the problem cannot be solved, you may have to contact your dealer or the factory. When you call for support, the representative will ask you to provide specific information about the installation. To save time, spend a few minutes getting organized before you telephone.
