Introduction 1 Introduction Welcome to Kramer Electronics (since 1981): a world of unique, creative and affordable solutions to the infinite range of problems that confront the video, audio and presentation professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 500-plus different models now appear in 8 Groups1, which are clearly defined by function. Congratulations on purchasing your Kramer VS-3232Vxl 32x32 Video Matrix Switcher.
Getting Started 2 KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview 3 Overview The Kramer VS-3232Vxl is a very high performance, superior x32 vertical interval matrix switcher for composite video signals on BNC connectors. It features a video bandwidth of over 500MHz that ensures transparent performance even in the most critical applications. Three SYNC switching options make the VS-3232Vxl appropriate for a wide range of glitch-free transition applications.
Your Video Matrix Switcher To achieve the best performance: Connect only good quality connection cables, thus avoiding interference, deterioration in signal quality due to poor matching, and elevated noise levels (often associated with low quality cables) Avoid interference from neighboring electrical appliances that may adversely influence signal quality and position your Kramer VS-3232Vxl in a location free from moisture and away from excessive sunlight and dust 4 Your Video Matrix Switcher Figure 1 an

Your Video Matrix Switcher 4.1 Using the IR Transmitter You can use the RC-IR2 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver1. The external IR receiver can be located up to 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables2.
-3232nd 5 Installing the VS-3232Vxl on a Rack This section describes what to do before installing on a rack and how to rack mount. Before Installing on a Rack Before installing on a rack, be sure that the environment is within the recommended range: How to Rack Mount To rack-mount a machine: 1 Attach both ear brackets to the machine. To do so, remove the screws from each side of the machine (5 on each side), and replace those screws through the ear brackets.
Connecting the Video Matrix Switcher 6 Connecting the Video Matrix Switcher You can install the VS-3232Vxl as: A composite video standalone switcher (see section 6.1) An s-Video switcher, by combining two VS-3232Vxl switchers: one unit for the Y signal and the second unit for the C signal (see section 6.2.1) A component video (YUV/RGB) switcher, by combining three VS-3232Vxl units: one for the Y signal, the second for the U signal and the third for the V signal (see section 6.2.
Connecting the Video Matrix Switcher Figure 3: Configuring the VS-3232Vxl for Composite Video 12 KRAMER: SIMPLE CREATIVE TECHNOLOGY
Connecting the Video Matrix Switcher 6.2 Assembling a Multi-channel Video Switcher You can configure several VS-3232Vxl units as 32x32 multi-channel video switchers for: s-Video (Y/C) by combining two VS-3232Vxl units (see section 6.2.1) YUV (RGB) by combining three VS-3232Vxl units (see section 6.2.2) RGBS by combining four VS-3232Vxl units (see section 6.2.3) In a multi-channel video switcher configuration, only one unit can be the Master (with DIP 6 OFF). The other units must be Slaves (with DIP 6 ON).
Connecting the Video Matrix Switcher 6.2.1 Configuring a 32x32 Y/C Switcher (Two Units) You can configure a 32x32 video matrix switcher for s-Video (Y/C), by combining two VS-3232Vxl switchers. Note that the machine number on both units must be identical. Although in the example in Figure 4 only one input1 and one output2 are connected, you can connect all the inputs and outputs in the same way to create a 32x32 Y/C switcher.
Connecting the Video Matrix Switcher 6.2.2 Configuring a 32x32 YUV/RGB Switcher (Three Units) Configure a 32x32 video matrix switcher for YUV/RGB by combining1 three VS-3232Vxl switchers. Note that the machine number on all three units must be identical. Although in the example in Figure 5 only one input2 and one output3 are connected, you can connect all the inputs and outputs in the same way to create a 32x32 YUV/RGB switcher.
Connecting the Video Matrix Switcher 6.2.3 Configuring a 32x32 RGBS Switcher (Four Units) Configure four VS-3232Vxl switchers as a 32x32 video matrix switcher for RGBS1, in a similar way to how Figure 5 in section 6.2.2 illustrates combining three VS-3232Vxl switchers for YUV (RGB). 6.
Connecting the Video Matrix Switcher 6.3.1 Setting the MACHINE # To control a unit remotely via RS-232, RS-485, IR or the Ethernet, each unit has to be identified via its unique Machine #. Set the Machine #1 on a VS-3232Vxl unit according to Table 4. Table 4: Machine # Dipswitch Settings Mach. # 1 2 3 4 5 6 7 8 6.3.2 DIP 1 ON OFF ON OFF ON OFF ON OFF DIP 2 OFF ON ON OFF OFF ON ON OFF DIP 3 OFF OFF OFF ON ON ON ON OFF DIP 4 OFF OFF OFF OFF OFF OFF OFF ON Mach.
Connecting the Video Matrix Switcher You must set DIP 5 ON to enable the FOLLOW-SYSTEM mode in an interconnected varied-format switcher application. You must set the machine number on each machine to a different value. Refer to section 7.7 for a description of the FOLLOW-SYSTEM and BREAKAWAY-FROM- SYSTEM modes MENUs. 6.3.
Connecting the Video Matrix Switcher 6.3.4 The System Mode versus the Master/Slave Mode The Follow mode seems similar to the Slave mode since in both modes the unit switches via commands from another unit. Table 5 summarizes the differences between the System mode and the Slave mode: Table 5: The System Mode versus the Slave Mode System Mode The unit can be switched in the Follow or Breakaway mode at any time, depending on the current application requirements. Any unit can be turned on or off at any time.
Connecting the Video Matrix Switcher 6.4.1 Connecting the RS-232 Control Interface You can connect several switchers (from the series of 32x32 or 16x16 matrix switchers) and the control unit in an RS-232 daisy chain arrangement, with or without using a Null-modem adapter, as Figure 7 illustrates. The RS-232 daisy chain switcher arrangement is transparent.
Connecting the Video Matrix Switcher 6.4.1.1 Connecting a PC to a VS-3232Vxl Unit via RS-232 To connect a PC to a VS-3232Vxl unit, using the Null-modem adapter provided with the machine (the default): 1. Connect the RS-232 IN DB9F rear panel port on the Master VS-3232Vxl unit to the Null-modem adapter and connect the Null-modem adapter with a 9-wire flat cable1 to the RS-232 DB9 port on your PC. 2. Set DIP 7 OFF2 (enabling Null-modem adapter use) on the VS-3232Vxl unit.
Connecting the Video Matrix Switcher 6.4.2 Connecting the RS-485 Control Interface Figure 8 defines the RS-485 connector PINOUT for external RS-485 control. The RS-485 connector is also used (if required) for vertical sync: Figure 8: RS-485 Connector PINOUT To connect an RS-485 connector on one VS-3232Vxl unit to an RS-485 connector on one or more other switchers (from the series of 32x32 or 16x16 matrix switchers), as Figure 9 illustrates: 1.
A B G Sync Connecting the Video Matrix Switcher Vertical Sync Figure 9: Connecting the RS-485 Connectors between two VS-3232Vxl Units Figure 10 illustrates the RS-485 line that connects: Between each VS-3232Vxl unit To the PC via a Kramer Tools VP-43xl Interface Converter (connect the PC’s DB 9 COM port to the RS-232 IN DB9F port on the VP-43xl.
