KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 1 HARDWARE 1.1 GENERALITIES The Kramer matrix switchers are used to select and dispatch electric signals, as audio, video and RGB, to several destination simultaneously. The impedances of each machine which is connected on the matrix are well respected, even if a signal goes to two outputs and more. As a matter of fact, a signal under 75 Ohms can’t be delivered on several loads without any amplification dispositive.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 1.3 CREATING A MATRIX The rear panel of the rack is 19” wide, on 3RU high. The mains, RS232 and RS422 plugs 1RU, and the useful area for the audio, video et RGB is also 1RU. The BNC or audio connectors are shared by 32, on horizontal bands which are 1RU wide. We can house up to 3 bands in a 3RU area, i.e. 96 BNC or audio plugs. So, we can realize a 32x64 video matrix, or a 64x32… When more, the rack has to be 6RU high.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER The cards are horizontally located, and can be extracted by the front panel. Each card own up to 32 stereo plugs. There is two types of audio cards : - Input audio cards. Called WMI, these cards are identical between themselves. The only differences are the serigraphy of the panel and its position in the slots. When viewing from the rear panel, these cards are immediately slotted near the QMOSD card (communication card).

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 2.4 COMMUNICATION PROTOCOL 2000 TM INCLUDING OPTIONS (02/09/2005 VER-5.06) 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.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 2nd BYTE: Bit 7 – Defined as 1. D6…D0 – “INPUT or DATA”. When switching (ie. instruction codes 1 and 2), the INPUT (MSB + 7 bits) is set as the input number which is to be switched. For other operations, these bits are defined according to the table. 3rd BYTE: Bit 7 – Defined as 1. A6…A0 – “OUTPUT or ADRESS”. When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER NOTES on the above table: NOTE 1 - These are bi-directional definitions. That is, if the switcher receives the code, it will perform the instruction; and if the instruction is performed (due to a keystroke operation on the front panel), then these codes are sent. For example, if the HEX code 01h 85h 88h 83h was sent from the PC, then the switcher (Layer 3 = YUV) will switch input 5 to output 8.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 5 TOUCH KEYBOARD : LUMINOUS RE-LABELABLE 5.1 PRESENTATION The keyboard permits the remote control of the switching matrix, without the use of a PC station. It is housed in 19" 1‘U’cabinet, with 8, 16, 24 or 32 selection, or in a built-in box. The selected key is illuminated. Each of the keys can be re-labelled, by writing in the name of the source or the destination. This keyboard is auto - powered by the matrix, via the RS422 connector.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 6 INCREMENTAL TOUCH KEYBOARD AND LCD DISPLAY 6.1 PRESENTATION 6.4 WORKING This keyboard permits the remote control of the switching matrix, without the use of a PC station. It is housed in a 19 inch 1U cabinet, with 2 keys for selection of the inputs, 2 keys of selection for the outputs, and a validation key. The configuration status of the switch actions selected is shown on the LCD display.

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER 7 MatrixOp4 SOFTWARE Destination Object connected on an output of the switcher. 7.1 INTRODUCTION The principle of the routing switcher is to connect each of its outputs to any or all of the inputs. Therefore the possible points of switching is a multiple of the number of inputs and the number of outputs. This principle is best described in the listview form. This grid is composed of switching points, and of distributors.

The switching off of power to the central unit (PC) and its screen doesn’t alter the connection of the matrix (as long as the matrix is powered). Disconnect A destination is disconnected when there is no link with any source. This status is symbolized by a fictive object that has to be assigned as a source called « disconnected ».

KRAMER E le c tro n ic s MATRIX ROUTING SWITCHER When the name and the connectors assignment is defined, you can choose the number of the touch, (or the step), you want to assign on your control panel. Selecting a touch will automatically assign it in the opened direction (source or destination). The touch will take the colour, blue for input, red for output, magenta for other special functions. The number of the touch is not necessary the same as the layers numbers.

On the right side, the four sources that are connected are shown, and can be changed. When the edition of the menu is finished, it is important to make a copy.
