1 Introduction Welcome to Kramer Electronics! Since 1981, Kramer Electronics has been providing a world of unique, creative, and affordable solutions to the vast range of problems that confront the video, audio, presentation, and broadcasting professional on a daily basis.
2 Getting Started We recommend that you: • Unpack the equipment carefully and save the original box and packaging materials for possible future shipment • Review the contents of this user manual • Use Kramer high performance high resolution cables • Use only the power cord that is supplied with this machine i 2.1 Go to http://www.kramerelectronics.com to check for up-to-date user manuals, application programs, and to check if firmware upgrades are available (where appropriate).
3 Overview The VS-5x5 is a true 5x5 matrix switcher for composite video signals and balanced stereo audio signals. The VS-5x5 lets you simultaneously route any or all of the 5 inputs to any or all of the 5 outputs.

5 Connecting the VS-5x5 5x5 Video Audio Matrix Switcher i Always switch off the power to each device before connecting it to your VS-5x5. After connecting your VS-5x5, connect its power and then switch on the power to each device. This section describes how to connect the VS-5x5. In particular, how to: 5.1 • Connect the VS-5x5 rear panel (see Section 5.1) • Control via RS-232, for example, using a PC (see Section 5.2) • Control via RS-485 (see Section 5.
5. Connect the power cord. We recommend that you use only the power cord that is supplied with this machine Figure 3: Connecting the VS-5x5 5x5 Video Audio Matrix Switcher 5.2 Connecting to the VS-5x5 via RS-232 You can connect to the unit via a crossed RS-232 connection, using for example, a PC. A crossed cable or null-modem is required as shown in method A and B respectively. If a shielded cable is used, connect the shield to pin 5.
5 4 3 2 9 8 7 6 9 8 7 6 1 5 4 3 2 PC 1 Figure 4: Crossed Cable RS-232 Connection Hardware flow control is not required for this unit. In the rare case where a controller requires hardware flow control, short pin 1 to 7 and 8, and pin 4 to 6 on the controller side. Method B (Figure 5)—Connect the RS-232 9-pin D-sub port on the unit via a straight (flat) cable to the null-modem adapter, and connect the null-modem adapter to the RS-232 9-pin D-sub port on the PC.
5.4 Connecting a Balanced/Unbalanced Stereo Audio Input/Output This section illustrates how to wire: • A balanced stereo audio connection, see Figure 6 • An unbalanced stereo audio input connection, see Figure 7 • An unbalanced stereo audio output connection, see Figure 8 Figure 6: Balanced Stereo Audio Connection 5.5 Figure 7: Unbalanced Stereo Audio Input Connection Figure 8: Unbalanced Stereo Audio Output Connection Setting the DIP-Switches Figure 9 describes the factory default DIP-switches.
5.5.1 Setting the MACHINE # The MACHINE # determines the position of a VS-5x5 unit, specifying which VS-5x5 unit is being controlled when several VS-5x5 units connect to a PC or serial controller. Set the MACHINE # on a VS-5x5 unit via DIPS 1, 2, 3 and 4, according to the following table. When using a stand-alone VS-5x5 unit, set the MACHINE # to 1. When connecting more than one VS-5x5 unit, set the first machine (the Master) that is closest to the PC, as MACHINE # 1 (all DIP-switches OFF).
6 Controlling via RS-232 and RS-485 You can cascade up to 8 VS-5x5 units with control from a PC or serial controller. To cascade up to 8 individual VS-5x5 units, via RS-232 and RS-485, do the following: 1. Connect the composite video sources and acceptors, as well as the appropriate stereo audio sources and acceptors, as Section 5.4 describes. 2. Connect the RS-232 port on the first VS-5x5 unit to the PC using the null-modem adapter provided with the machine (recommended), as described in Section 5.2.

7 Operating the VS-5x5 You can operate your VS-5x5 via: • The front panel buttons • RS-232/RS-485 serial commands transmitted by a touch screen system, PC, or other serial controller • 7.
7.2 Choosing the Audio-Follow-Video or Breakaway Option You can switch stereo audio signals in one of two ways, either: • Audio-follow-video (AFV), where all operations and status indicators relate to both the video and the audio channels or Audio and video connections are the same • 7.2.1 Breakaway, where video and audio channels switch independently Setting the Audio-Follow-Video Option To set the audio-follow-video (AFV) option: 1. Press the AFV button. The AFV button illuminates.
2. Press an IN button (1, 2, 3, 4 or OFF). The selected input switches to the selected output. For example, press the ALL button and then IN button # 2 to connect input # 2 to all the outputs. 7.4 Confirming Settings Choose to work in the AT ONCE or the CONFIRM mode. When the VS-5x5 operates in the AT ONCE mode (TAKE button is not lit), pressing an OUT-IN combination implements the switch immediately. In the CONFIRM mode (TAKE button is lit), the TAKE button must be pressed to authorize the switch.
Actions no longer require user confirmation and the TAKE button no longer illuminates. 7.4.2 Confirming a Switching Action To confirm a switching action (in CONFIRM mode), do the following: 1. Press an OUT-IN combination. The corresponding 7-segment display flashes. The TAKE button also flashes. 2. Press the flashing TAKE button to confirm the action. The corresponding 7-segment display no longer flashes. The TAKE button illuminates. 3.
7.5.1 Storing an Input/Output Configuration To store the current status in memory, do the following: 1. Press the STO button. The STO button flashes. 2. Press one of the 10 input /output buttons (this is the setup # in which the current status is stored). If in the CONFIRM mode, press the flashing TAKE button to confirm the action. The memory stores the data at that reference. 7.5.2 Recalling an Input/Output Configuration To recall an input/output configuration, do the following: 1. Press the RCL button.
7.6 Locking the Front Panel To prevent changing the settings accidentally or tampering with the unit via the front panel buttons, lock your VS-5x5. Unlocking releases the protection mechanism. Nevertheless, even though the front panel is locked you can still operate via RS-232 or RS-485, as well as via the Kramer To lock the VS-5x5: • Press the LOCK button for more than two seconds, until the LOCK button is illuminated The front panel is locked.

11 Kramer Protocol 2000 The VS-5x5 is compatible with Kramer’s Protocol 2000 (version 0.5) (below). This RS-232 / RS-485 communication protocol uses four bytes of information as defined below. For RS-232, a null-modem connection between the machine and controller is used. The default data rate is 9600 baud, with no parity, 8 data bits and 1 stop bit.
Used to address machines in a system via their machine numbers. When several machines are controlled from a single serial port, they are usually configured together with each machine having an individual machine number. If the OVR bit is set, then all machine numbers will accept (implement) the command, and the addressed machine will reply. For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1.

NOTE 9 - An error code is returned to the PC if an invalid instruction code was sent to the switcher, or if a parameter associated with the instruction is out of range (e.g. trying to save to a setup greater than the highest one, or trying to switch an input or output greater than the highest one defined). This code is also returned to the PC if an RS-232 instruction is sent while the machine is being programmed via the front panel. Reception of this code by the switcher is not valid.
NOTE 19 – When data (i.e. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, this instruction is sent before sending the instruction needing the additional bits. The data in this instruction then becomes the Most Significant Bits of that next instruction.
