General Rear Panel Connections Rear Panel Overview This chapter covers the types of input and output connections, switches and indicators on the rear panel of the System 8/10 PLUS. Rear Panel Controls and Indicators The following list refers to each input channel (left diagram): 1. Input LEDs: Green LED indicator (1-8 or 1-10) lights to indicate selected input. 2. Audio Level: An audio level attenuator is provided for each input channel (1-8 or 1-10) to normalize audio output levels.
General Rear Panel Connections Input Section Each input channel of the System 8/10 PLUS has the following: • A set of five BNC connectors mounted vertically. • A six-pin audio connector located below each set of BNC connectors. • A green LED indicator above each set of BNC connectors ( ) lights to indicate that this input is selected. (Only one input can be selected at a time.
Rear Panel Connections Applications Applications The illustration shows examples of some of the equipment that can be connected to a System 8/10 PLUS switcher.
Video Input Rear Panel Connections Input Configurations Each System 8/10 PLUS switcher input can be configured for any of the following RGB connections: • • • • • RGB - Red, Green/sync, Blue (3 cables) RGBS - Red, Green, Blue, and Composite Sync (4 cables) RGBHV - Red, Green, Blue and Separate H & V Sync (5 cables) Composite (NTSC/PAL) - Using the G connector (1 cable) S-Video/S-VHS - Using the G connector for Y and H/HV connector for C (2 cables) All video inputs to the System 8/10 PLUS use BNC connec
Video Output Rear Panel Connections Video Output Connections The System 8/10 PLUS has three sets of BNC output connectors (RGBHV, Composite, and S-Video). Which output connectors are active depends upon which type of input is selected. These connectors provide outputs from the System 8/10 PLUS to the video projector or display monitor. When an input channel is selected, the corresponding LED lights to show the format of the selected video and which output is being used.
Audio Input/Output Rear Panel Connections Audio Connections The System 8/10 PLUS can accept audio from two different sets of input connectors. Left and right audio can use the R and B BNC connectors shown to the left (labeled R Audio and L Audio). Audio can also use the 6-pin Phoenix® brand of captive screw connector shown at the bottom of each input and output.
RGB Input Rear Panel Connections RGB (Analog) Input Connections Each switcher input can be configured for any of the following RGB connections: • RGB - Red, Green/sync, Blue (3-cables) • RGBS - Red, Green, Blue, and Composite Sync (4-cables) • RGBHV - Red, Green, Blue, H & V Sync (5-cables) Any of these inputs may include audio follow, using the Phoenix® audio connectors. If the video source does not have audio, audio can be connected from another source.
NTSC/PAL Input Rear Panel Connections Composite Video (NTSC/PAL) Input Connections NTSC (National Television Standards Committee) and PAL (Phase Alternate Line) composite video signals use a single coax cable. They may or may not have separate audio. See the illustration below to connect a composite video source to the input of a System 8/10 PLUS. If the source has stereo audio, it can be connected either of two ways. The solid line shows the use of a Phoenix® audio connector that has six (6) conductors.
S-Video Input Rear Panel Connections S-Video Input Connections S-Video or S-VHS is typically an output from the AV source on a 4-pin miniature DIN type connector which must be converted to 2 BNC type connectors – one for chrominance (C) and the other for luminance (Y) - [Extron adapter cable 26-35301]. S-Video input to the System 8/10 PLUS is made by connecting the chroma (C) to the H/HV/C input connector and the luminance (Y) to the G/Video/Y input connector.
Video Loop Back Rear Panel Connections Video Loop Back (VLB) Video Loop Back (VLB) is a special feature which allows a scan doubler (also called “line-doubler”) or an RGB decoder to be used with the System 8/10 PLUS switcher. With VLB enabled, any input can use an RGB decoder or a scan doubler without recabling. This reduces the amount of equipment needed for a system that requires the use of either of these devices.
Video Loop Back Rear Panel Connections VLB Operation The illustration below is an example of a decoder being used in Video Loop Back, however, it could be any one of several types of decoders or line doublers. When VLB is active, the System 8/10 PLUS operates as follows: 1. Composite video and S-Video sources are connected to any of the System 8/10 PLUS inputs except the last one. 2. Standard RGB inputs exit the switcher through the normal RGB output. 3.
Special Features Rear Panel Connections Special Features The System 8/10 PLUS has some special features, one of which is Auto Sync Detect. Auto Sync Detect determines what type of RGB sync is being input. Sometimes this feature must be disabled when connecting to certain projectors. For example, if a Barco projector is powered up with no input yet present at the switcher, the projector will not detect any sync and will default to sync on Green.
Rack Mounting Rear Panel Connections Cabling a System 8/10 PLUS in a Rack When routing cables from one unit to another in a rack, do NOT allow the cables to pull down on the equipment. Use “Tie Wraps”, “Rip-Ties” or other devices to secure the cables at some location in the rack that is above the rear panel connectors. Loosely hanging cables may be stepped on, resulting in damage to cables and equipment, as well as injury to personnel. The illustration shows the rear view of a system rack.

Up to 17 switchers can be looped together, providing a total of 154 inputs (using all System 10 PLUS switchers).
Multiple Switcher Operation Looping DIP Switch Types Before going into the switch setups, let us first explain that there are different types of DIP switches, some "slide" and some "rock". Your System 8/10 PLUS could have either type DIP switch. Although they operate differently and are labeled differently, they are simply on/off (open/closed) switches. Regardless of the type of switch, we will show the positions as "up" or "down" and will use arrows to show the switch position.
Multiple Switcher Operation Daisy Chain Configuration Daisy Chain Connection Daisy Chain configuration refers to routing the output of the first slave (#0) into the last input of the master switcher, and the output of the second slave (#1) into the last input of slave #0... etc. All other inputs are used for various video sources. The maximum number of inputs available in the daisy-chain configuration is 154 when using all System 10 PLUS switchers (120 when using all System 8 switchers).
Multiple Switcher Operation Daisy Chain Configuration Daisy Chain Example The illustration below shows how System 8/10 PLUS units would be connected in a Daisy Chain configuration. If System 10 PLUS units were used, the only difference would be the input channel numbers. _____ Important audio information! If audio connections are made balanced, there will be +6 dB of gain. This gain must be offset with a pad, otherwise the maximum input audio level could be exceeded on the audio input.
Multiple Switcher Operation Star Configuration Star Connection In a Star configuration, the output of each slave supplies an input to the master switcher. There is no slave #0 in a Star configuration. For example, slave #1 is connected to input #1 of the master switcher; slave #2 is connected to master input #2, etc. The output of the Master is connected to the projector or display monitor.
