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-41HD 4x1 HD/SD-SDI Switcher / DA 6 Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA You can use your VS-41HD to switch one of the four standard definition / high definition SDI inputs to the two identical high definition / standard definition SDI outputs, as the illustration in Figure 2 shows. To connect the VS-41HD 4x1 HD/SD-SDI Switcher / DA, as shown in the example in Figure 2, do the following 1: 1.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA Figure 2: Connecting the VS-41HD 4x1 HD/SD-SDI Switcher / DA 6.1 Dipswitch Settings By default, all dipswitches are set to OFF.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA 6.1.1 Setting the Machine ID Dipswitches The Machine ID determines the position of a VS-41HD unit, specifying which VS-41HD unit is being controlled when several VS-41HD units connect to a PC or serial controller. Set the Machine number on a VS-41HD unit via MACH. ID DIPS 1, 2, 3 and 4, according to Table 3. When using a standalone VS-41HD unit, set the Machine ID to 1.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA 6.3 Controlling via the RS-485 Port To cascade up to eight individual VS-41HD 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-41HD units.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA 6.4 Switching two Genlocked Video Signals The genlock feature lets you switch genlocked video signals according to timing of the GENLOCK reference input 1. Connect the GENLOCK cable. If the HD input signal 2 that is connected is one of the following, it is necessary to set it up as follows: • 1080i@60Hz: press and hold INPUT 1 button for 3 seconds.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA 4. Select Properties. The Local Area Connection Properties window appears. 5. Select the Internet Protocol (TCP/IP) and click the Properties Button (see Figure 6). Figure 6: Local Area Connection Properties Window 6. Select Use the following IP address, and fill in the details as shown in Figure 7. 7. Click OK.
Connecting Your VS-41HD 4x1 HD/SD-SDI Switcher / DA 6.5.2 Connecting the ETHERNET Port via a Network Hub (StraightThrough Cable) You can connect the Ethernet port of the VS-41HD to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors. 6.5.3 Configuring the Ethernet Port After connecting the Ethernet port, you have to install and configure it.
Operating the VS-41HD 7 Operating the VS-41HD You can operate your VS-41HD via: • The front panel buttons • RS-232/RS-485 serial commands transmitted by a PC, touch screen system, or other serial controller • The Kramer infrared remote control transmitter • The ETHERNET To switch an input to the outputs via the front panel buttons 1, press the desired input button. When selecting an input that is not connected, that input button blinks. 7.
Technical Specifications 8 Technical Specifications Table 4 includes the technical specifications: 1 Table 4: Technical Specifications of the VS-41HD 4x1 HD/SD-SDI Switcher / DA INPUTS: OUTPUTS: MAX.
Kramer Protocol 2000 9 Kramer Protocol 2000 The VS-41HD is compatible with Kramer’s Protocol 2000 (version 0.46) (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.
Kramer Protocol 2000 Table 6: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
Kramer Protocol 2000 If the OUTPUT is set as 1, then the ASCII coding of the lettering following the machine’s name is sent. For example, for the VS-7588YC, the reply to the request to send the first suffix would be (HEX codes): 7D D9 C3 81 (i.e. 128dec+ ASCII for “Y”; 128dec+ ASCII for “C”). NOTE 16 - The reply to the “REQUEST WHETHER PANEL IS LOCKED” is as in NOTE 4 above, except that here the OUTPUT is assigned with the value 0 if the panel is unlocked, or 1 if it is locked.
