Overview 3 Overview The high performance VS-626 (VS-828) is a true vertical interval Video / Audio Matrix Switcher, letting you route any input to any or all of the outputs simultaneously.
Your VS-626 (VS-828) Video Audio Matrix Switcher Control the VS-626 (VS-828) using the front panel buttons, or remotely via the Kramer RC-IR2 Infra-Red Remote Control Transmitter, or via an external remote IR receiver (optional), or via RS-232 or RS-485 serial commands transmitted by a touch screen system, PC, or other serial controller The VS-626 (VS-828) is dependable, rugged and fits into two vertical spaces (2U) of a standard 19" rack.

Installing on a Rack 5 Installing on a Rack This section describes what to do before installing on a rack and how to rack mount.
Connecting the VS-828 Video / Audio Matrix Switcher 6 Connecting1 the VS-828 Video / Audio Matrix Switcher To connect a single2 VS-828 switcher, as illustrated in the example in Figure 3, do the following3: 1. Connect up to 8 (6) composite video sources (for example, composite video players) to the VIDEO INPUT BNC connectors and the AUDIO INPUT R and L RCA connectors4. 2.

Connecting the VS-828 Video / Audio Matrix Switcher 6.1 Setting the Dipswitches This section describes the machine set-up and dipswitch selection. Figure 4 and Table 3 describe the VS-828 dipswitches.
Connecting the VS-828 Video / Audio Matrix Switcher Up to 8 Matrix Switchers may be cascaded for control via a single port by configuring one Matrix Switcher as a Master (Self Address = 1)1, while all the others are assigned as Slave Matrix Switchers or an ID other than "1". 6.1.2 Setting Connection Dipswitches When connecting a PC via the RS-232, set dipswitch # 8 to ON. When connecting a PC via the RS-485, set dipswitch # 8 to OFF.
Connecting the VS-828 Video / Audio Matrix Switcher 6.3 Controlling via RS-232 and RS-485 You can control up to eight single VS-828 units with control from a PC via RS-232 (see section 6.2) and RS-485 as illustrated in Figure 6. To control via RS-232 and RS-485, do as follows: 1. Connect the video sources and acceptors, the appropriate audio sources and acceptors, and the power cord to each VS-828 unit. 2. On each VS-828 unit, set the Self Address dipswitches, as required1 (see Table 4). 3.
Connecting the VS-828 Video / Audio Matrix Switcher 6.4 RGB/YUV Switching with RS-232 (PC Control) Figure 7 describes a typical component video/RGB setup where every video signal is composed of three sub signals (components), which should be switched together (also valid for YUV components). For RS-232 control of the component matrix switcher, an additional piece of equipment would be required. Since RS-232 can only be used for control between 2 pieces of equipment (e.g.

Operating VS-828 Matrix Switcher 7 Operating VS-828 Matrix Switcher Operate your VS-828 via: The front panel buttons RS-232/ RS-485 serial commands transmitted by a touch screen system, PC or other serial controller 7.
Operating VS-828 Matrix Switcher 7.3 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 relate to both the video and the audio channels; or Breakaway, in which video and audio channels switch independently 7.3.
Operating VS-828 Matrix Switcher 7.4.2 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 SELECTOR button (the INPUT SELECTOR button # corresponding to the setup #). The memory recalls the stored data from that reference. 7.4.3 Deleting an Input/Output Configuration To delete an input/output configuration, do the following: 1. Press the STO and RCL buttons simultaneously.

Communication Protocol 9 Communication Protocol Communication with the Matrix Switchers described in this manual uses four bytes of information as defined in Table 6 Data is transferred at 9600 baud with no parity, 8 data bits and 1 stop bit.
Communication Protocol Table 7: Protocol Instruction Codes Note: All values in the table are decimal, unless otherwise stated.
Communication Protocol When the PC sends one of the commands in this group to the switcher, then, if the instruction is valid, the switcher replies by sending to the PC the same four bytes that it sent (except for the first byte, where the DESTINATION bit is set "high"). NOTE 3 - 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.
Table of Hex Codes for the Master VS-828 10 Table of Hex Codes for the Master VS-828 Table 8 shows the “ HEX” codes for switching the Master VS-828.
