Introduction 1 Introduction Welcome to Kramer Electronics (since 1981): a world of unique, creative and affordable solutions to the infinite range of problems that confront the video, audio and presentation professional on a daily basis. In recent years, we have redesigned and upgraded most of our line, making the best even better! Our 500-plus different models now appear in 8 Groups1, which are clearly defined by function.
Getting Started 2 KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview 3 Overview The VS-202YC is a 2x1:2 switcher and distribution amplifier for s-Video signals that lets you switch either the signal at input 1 or input 2 to two identical outputs.

Connecting the VS-202YC 2x1:2 s-Video Switcher / DA 5 Connecting the VS-202YC 2x1:2 s-Video Switcher / DA To connect1 the VS-202YC 2x1:2 s-Video Switcher / DA, 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 connectors to the acceptors (for example, an s-Video recorder to OUTPUT 1 and an s-Video recorder to OUTPUT 2).
Connecting the VS-202YC 2x1:2 s-Video Switcher / DA 5.1 Connecting a PC You can connect a PC to the VS-202YC via the RS-232 port.
Flash Memory Upgrade 6 Flash Memory Upgrade The VS-202YC 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-202YC (for example, 202YCM_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 VS202YC.hex Figure 14: Atmel – Flip Window (Operation Completed) 10. Close the “Atmel – Flip” window. 11. Disconnect the power to the VS-202YC. 12. Disconnect the RS-232 rear panel port. 13. Switch to OFF on the machine underside. 14.

VS-202YC Communication Protocol 9 VS-202YC Communication Protocol The VS-202YC 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.
VS-202YC Communication Protocol Table 6: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
VS-202YC Communication Protocol # DEFINITION FOR SPECIFIC INSTRUCTION INPUT OUTPUT 16 ERROR / BUSY For invalid / valid input (i.e.
VS-202YC Communication Protocol # INSTRUCTION DESCRIPTION DEFINITION FOR SPECIFIC INSTRUCTION INPUT OUTPUT 43 VIDEO PARAMETER SETTINGS FOR INSTRUCTIONS 21, 23, 26 1 – Input 2 – Output 56 CHANGE TO ASCII 0 57 SET AUTO-SAVE 58 I3 - no save I4 - auto-save Set as 0, or as SETUP #.
VS-202YC Communication Protocol NOTE 6 – If INPUT is set to 127 for these instructions, then, if the function is defined on this machine, it replies with OUTPUT=1. If the function is not defined, then the machine replies with OUTPUT=0, or with an error (invalid instruction code). If the INPUT is set to 126 for these instructions, then, if possible, the machine will return the current setting of this function, even for the case that the function is not defined.
VS-202YC Communication Protocol code is sent again. (The mode is automatically cancelled after implementation of the switch if the “execute” command is used). For example, to connect input 4 to output 3 after a delay, send HEX codes 07 80 C0 81 (set for delayed switch) 01 84 83 81 (switch code) then, after the required delay, send HEX codes 07 80 C1 81 (execute delayed switch) to implement the switch.
