Installing on a Rack 5 Installing on a Rack This section describes what to do before installing in a rack and how to rack mount.
Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher 6 Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher You can use your VS-88HD to switch one of the eight standard definition / high definition SDI inputs to any or all of the eight standard definition / high definition SDI outputs, as the example in Figure 2 shows. To connect the VS-88HD 8x8 SD/HD-SDI Matrix Switcher, do the following1: 1.
Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher Figure 2: Connecting the VS-88HD 8x8 SD/HD-SDI Matrix Switcher 6.1 DIP-switch Settings By default, DIP-switches 2, 3 and 4 are set to ON (for setting the machine number to 1) and the other DIP-switches are set to OFF.
Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher 6.1.1 Setting the Machine # DIP-switches The Machine # determines the position of a VS-88HD unit, specifying which VS-88HD unit is being controlled when several VS-88HD units connect to a PC or serial controller. Set the Machine # on a VS-88HD unit via SETUP DIPS 1, 2, 3 and 4, according to Table 3. When using a standalone VS-88HD unit, set the Machine # to 1.
Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher 6.3 Controlling via the RS-485 Port To cascade up to eight individual VS-88HD units, via RS-485 (with control via a Master Programmable Remote Control system such as the Kramer RC-3000), as Figure 5 illustrates, do the following: 1. Connect the “A” (+) and “B” (-) PINS on the RS-485 terminal block port of the RC-3000 to the “A” (+) and “B” (-) PINS, respectively, on each of the eight VS-88HD units.
Connecting Your VS-88HD 8x8 SD/HD-SDI Matrix Switcher 6.4 Genlock Switching The following Genlock switching procedures apply to firmware version 2.2 and higher.
Operating the VS-88HD 7 Operating the VS-88HD You can operate your VS-88HD via the front panel buttons, and/or RS-232/RS-485 serial commands transmitted by a PC, touch screen system, or other serial controller. 7.1 Switching OUT-IN Combinations To switch an input to an output via the front panel buttons, in the AT ONCE mode (see section 7.2), do the following: 1. Press an OUT SELECT button1 or the ALL button. The input under the selected output on the 7-segment display blinks. 2.
Operating the VS-88HD 7.2.1 Toggling between the AT ONCE and CONFIRM Modes To toggle between the AT ONCE and CONFIRM modes, do the following: 1. Press the dim TAKE button twice (the button blinks and then illuminates) to toggle from the AT ONCE mode (in which the TAKE button is dim) to the CONFIRM mode (in which the TAKE button illuminates). Actions now require user confirmation and the TAKE button illuminates. 2.
Technical Specifications 7.3.1 Storing an Input/Output Configuration To store the current status in memory, do the following: 1. Press the STO button. The STO button blinks. 2. Press one of the OUT SELECT buttons (this will be the setup # in which the current status is stored). The number of the selected setup # blinks on the display and the STO button continues blinking. 3. Press the STO button again. The STO button stops blinking. 7.3.

Kramer Protocol 2000 10 Kramer Protocol 2000 The VS-88HD is compatible with Kramer’s Protocol 2000 (version 0.51) (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.
