Your VS-808YC 8x8 s-Video / Audio Matrix Switcher 4.1 Using the IR Transmitter You can use the RC-IR3 IR transmitter to control the machine via the built-in IR receiver on the front panel or, instead, via an optional external IR receiver1. The external IR receiver can be located 15 meters away from the machine. This distance can be extended to up to 60 meters when used with three extension cables2.
Installing the VS-808YC on a Rack 5 Installing the VS-808YC on a Rack This section describes what to do before installing on a rack and how to rack mount.
Connecting the VS-808YC 6 Connecting the VS-808YC This section describes how to connect the VS-808YC. In particular, how to: Connect the VS-808YC rear panel (see section 6.1) Control via RS-232, for example, using a PC (see section 6.2) Control via RS-485 (see section 6.3) Connect the audio inputs/outputs (see section 6.4) Set the DIP-switches (see section 6.5) 6.1 Connecting the VS-808YC Rear Panel To connect the VS-808YC, as the example in Figure 3 illustrates, do the following1: 1.

Operating the VS-808YC 8 Operating the VS-808YC You can operate your VS-808YC via: The front panel buttons RS-232/RS-485 serial commands transmitted by a touch screen system, PC, or other serial controller Infrared remote control transmitter 8.
Operating the VS-808YC 8.2 Choosing the Audio-Follow-Video or Breakaway Option You can switch stereo audio signals in one of two ways, either: Audio-follow-video (AFV), in which all operations and status indicators relate to both the video and the audio channels1; or Breakaway, in which video and audio channels switch independently 8.2.1 Setting the Audio-Follow-Video Option To set the Audio-follow-video (AFV) option: 1. Press the AFV button. The AFV button illuminates. The audio will follow the video.
Operating the VS-808YC 8.4 Confirming Settings Choose to work in the AT ONCE or the CONFIRM mode, as section 8.4.1 describes. When the VS-808YC operates in the AT ONCE mode, pressing an OUT-IN combination implements the switch immediately. In the CONFIRM mode, the TAKE button must be pressed to authorize the switch. In the AT ONCE mode, you save time as execution is immediate and actions require no user confirmation. However, no protection is offered against changing an action in error.
Operating the VS-808YC To confirm several actions (in CONFIRM mode), do the following: 1. Press each OUT-IN combination in sequence. The corresponding digits in the 7-segment Display blink. The TAKE button also blinks. 2. Press the blinking TAKE button to confirm all the actions. The corresponding digits in the 7-segment Display no longer blink. The TAKE button illuminates. 8.
Operating the VS-808YC 8.5.2 Recalling an Input/Output Configuration To recall an input/output configuration, do the following: 1. Press the RCL button. The RCL button blinks. 2. Press the appropriate Input / Output button (the button # corresponding to the setup #). If in the CONFIRM mode, that setup configuration will blink in the STATUS 7-segment Display, together with the RCL button and the TAKE button, and will only be implemented after pressing the TAKE button.
Operating the VS-808YC To unlock the VS-808YC: Press the illuminated LOCK button for more than two seconds, until the LOCK button is no longer illuminated The front panel unlocks 8.7 Resetting the VS-808YC You can reset the VS-808YC unit to the: Current status1 (reloads the current setup2) Factory default (resets to the pre-installed factory default state) 8.7.1 Resetting to the Current Status You can reset the VS-808YC unit to the current status (reloads the current setup).
Flash Memory Upgrade 9 Flash Memory Upgrade The VS-808YC firmware is located in FLASH memory, which lets you upgrade to the latest Kramer firmware version in minutes! The process involves: Downloading from the Internet (see section 9.1) Connecting the PC to the RS-232 port (see section 9.2) Upgrading Firmware (see section 10) 9.1 Downloading from the Internet You can download the up-to-date file from the Internet. To do so: 1. Go to our Web site at http://www.kramerelectronics.

Kramer Protocol 2000 13 Kramer Protocol 20001 The VS-808YC is compatible with Kramer’s Protocol 2000 (version 0.42) (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 For a single machine controlled via the serial port, always set M4…M0 = 1, and make sure that the machine itself is configured as MACHINE NUMBER = 1. Table 9: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.
Kramer Protocol 2000 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.
Kramer Protocol 2000 then, after the required delay, send HEX codes 07 80 C1 to implement the switch. 81 (execute delayed switch) NOTE 18 – After this instruction is sent, the unit will respond to the ASCII command set. The ASCII command to operate with the HEX command set must be sent in order to return to working with HEX codes. NOTE 19 – When data (ie. the INPUT and/or OUTPUT bytes) of more than 7 bits is required, this instruction is sent before sending the instruction needing the additional bits.
