Connecting the VS-121HC Switcher/Transcoder 6 Connecting the VS-121HC Switcher/Transcoder To connect devices to the VS-121HC, as illustrated in the example in Figure 2, perform the following 1: 1.
Operating the VS-121HC Switcher/Transcoder Figure 2: Connecting the VS-121HC Switcher / Transcoder 7 Operating the VS-121HC Switcher/Transcoder You can operate the VS-121HC using: • The front panel buttons (see section 7.1) • The RS-232 port (see section 7.2) • The RS-485 port (see section 7.3) • An Ethernet network (see section 7.4) • The RC-IR2 remote control transmitter 1 (see section 7.5) This section also describes: • How to set the DIP-switches (see section 7.
Operating the VS-121HC Switcher/Transcoder 7.1 Operating Using the Front Panel Buttons The front panel includes 4 COMPOSITE input, 4 s-VIDEO input, 4 COMPONENT input, and one PANEL LOCK button. To operate the unit: • Press one of the 12 INPUT SELECTOR buttons to choose the relevant video signal.
Operating the VS-121HC Switcher/Transcoder Note: There is no need to connect any other pins. Figure 3: 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.
Operating the VS-121HC Switcher/Transcoder 7.3.1 Setting the Machine number Set the first or master device to machine #1. Set all other devices to other unique machine numbers, as defined in Table 4. 7.3.2 Setting the Line Termination To ensure correct operation, the RS-485 line must be terminated at both ends. The master unit may be located at any part of the line, but when it is at the end of the line, the termination switch must be set ON.
Operating the VS-121HC Switcher/Transcoder 7.4 Operating via the ETHERNET Port You can operate the VS-121HC via the Ethernet, using a crossover cable (see section 7.4.1) for direct connection to the PC or a straight through cable (see section 7.4.2) for connection via a network hub or network router. 7.4.1 Connecting the ETHERNET Port directly to a PC (Crossover Cable) You can connect the Ethernet port of the VS-121HC to the Ethernet port on your PC, via a crossover cable with RJ-45 connectors.
Operating the VS-121HC Switcher/Transcoder 6. Select Use the following IP address, and fill in the details as shown in Figure 7. 7. Click OK. Figure 7: Internet Protocol (TCP/IP) Properties Window 7.4.2 Connecting the ETHERNET Port via a Network Hub (Straight-Through Cable) You can connect the Ethernet port of the VS-121HC to the Ethernet port on a network hub or network router, via a straight-through cable with RJ-45 connectors. 7.4.
Operating the VS-121HC Switcher/Transcoder 7.5 Operating via the Infrared Remote Controller 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 receiver 1. The external IR receiver can be located 15 meters away from the machine.
Operating the VS-121HC Switcher/Transcoder DIP-switches 1, 2, 3, and 4 determine the machine number of the VS-121HC. DIP-switches 5 and 6 are not used. DIP-switch 7 determines operation in tandem with the Kramer VS-121HCA. DIP-switch 8 determines . the RS-485 bus termination for the VS-121HC. When several product units are connected, the machine number determines the unique identity of the VS-121HC in the sequence (see section 7.6).
Operating the VS-121HC Switcher/Transcoder 7.7 Operating the VS-121HC in Tandem with the VS-121HCA The VS-121HC can operate in tandem with the Kramer VS-121HCA 12x1 Stereo Audio – S/PDIF Switcher. Once the units are connected, you can operate the system via the front panel buttons of the VS-121HC or via the RS-232 or the Ethernet ports of the VS-121HC. To set the VS-121HC to operate in tandem with the VS-121HCA: 1. Set the machine number on both units to 1 (DIP-switches 1, 2, 3 and 4 are set OFF). 2.
