Connecting the VS-201YC 2x1 s-Video Switcher 5 Connecting the VS-201YC 2x1 s-Video Switcher To connect1 the VS-201YC 2x1 s-Video Switcher, as the example in Figure 5 illustrates, do the following: 1. Connect the two s-Video sources to the s-Video INPUT 4p connectors (for example, an s-Video player to INPUT 1 and an s-Video player to INPUT 2). 2. Connect the s-Video OUTPUT 4p connector to the acceptor (for example, an s-Video recorder). 3. If required, connect a PC to the RS-232 port2, see section 5.1. 4.
Connecting the VS-201YC 2x1 s-Video Switcher 5.1 Connecting a PC You can connect a PC to the VS-201YC via the RS-232 port.
Flash Memory Upgrade 6 Flash Memory Upgrade The VS-201YC firmware is located in FLASH memory, which lets you upgrade1 to the latest Kramer firmware version in minutes! The process involves: Downloading from the Internet (see section 6.1) Connecting the PC to the RS-232 port (see section 6.2) Upgrading Firmware (see section 6.3) 6.1 Downloading from the Internet You can download the up-to-date file2 from the Internet. To do so: 1. Go to our Web site at http://www.kramerelectronics.
Flash Memory Upgrade 6.3 Upgrading Firmware Follow these steps to upgrade the firmware: 1. Double click the desktop icon: “Shortcut to FLIP.EXE”. The Splash screen appears as follows: Figure 7: Splash Screen 2. After a few seconds, the Splash screen is replaced by the “Atmel – Flip” window: Figure 8: Atmel – Flip Window 3. Press the keyboard shortcut key F2 (or select the “Select” command from the Device menu, or press the integrated circuit icon in the upper right corner of the window).
Flash Memory Upgrade 4. Click the button next to the name of the device and select from the list: AT89C51RD2: AT89C51RD2 T89C51RD2 Figure 10: Selecting the Device from the Selection Window 5. Click OK and select “Load Hex” from the File menu.
Flash Memory Upgrade 6. The Open File window opens. Select the correct HEX file that contains the updated version of the firmware for VS-201YC (for example, 201YCM_V1p2.hex) and click Open. 7. Press the keyboard shortcut key F3 (or select the “Communication / RS232” command from the Settings menu, or press the keys: Alt SCR). The “RS232” window appears. Change the COM port according to the configuration of your computer and select the 9600 baud rate: Figure 12: RS-232 Window 8. Click Connect.
Flash Memory Upgrade 9. Click Run. After each stage of the operation is completed, the check-box for that stage becomes colored green1. When the operation is completed, all 4 check-boxes will be colored green and the status bar message: Memory Verify Pass appears2: A VS201YC.hex Figure 14: Atmel – Flip Window (Operation Completed) 10. Close the “Atmel – Flip” window. 11. Disconnect the power to the VS-201YC. 12. Disconnect the RS-232 rear panel port on the VS-201YC unit from the Null-modem adapter. 13.

Table of Hex Codes for Serial Communication 8 Table of Hex Codes for Serial Communication Table 4 lists the Hex values for switching on the VS-201YC. Table 4: Hex Codes IN 1 IN 2 OUT 2 1 9 VS-201YC Communication Protocol The VS-201YC 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.
VS-201YC Communication Protocol When switching (ie. instruction codes 1 and 2), the OUTPUT (7 bits) is set as the output number which is to be switched. Similarly, if switching is done via the machine’s front-panel, then these bits are set with the OUTPUT NUMBER which was switched. For other operations, these bits are defined according to the table. 4th BYTE: Bit 7 – Defined as 1. Bit 5 – Don’t care. OVR – Machine number override. M4…M0 – MACHINE NUMBER.

VS-201YC Communication Protocol NOTE 4 - The reply to a "REQUEST" instruction is as follows: the same instruction and INPUT codes as were sent are returned, and the OUTPUT is assigned the value of the requested parameter. The replies to instructions 10 and 11 are as per the definitions in instructions 7 and 8 respectively.
VS-201YC Communication Protocol 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. NOTE 17 – For clean switching of RGBHV video, the “seamless switching” option may be used. The blanking period for the transition of the RGB sources may be set in this case, in steps of 25 milliseconds.
