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.
Overview 3 Overview The VS-44HC is a true 4x4 matrix switcher for YUV (Y, Pb/Cb, Pr/Cr) component video and digital audio (S/PDIF) signals. The high quality VS-44HC lets you simultaneously route any of the 4 inputs to any or all of the 4 outputs. The component video and S/PDIF input and output signals are on RCA connectors, and the S/PDIF channel 2 is also available on optical (TOSLINK1) input/output connectors.

Table of Hex Codes for Serial Communication 11 Table of Hex Codes for Serial Communication Sections 11.1 and 11.2 contain the tables of hex codes for switching and setting the delay time, respectively. 11.
Table of Hex Codes for Serial Communication For delay times exceeding 127ms, you need to send two commands (eight bytes). The first command includes the most significant bits: Byte 1 should be 63 (7FH) Byte 2 should be 127 (80H) plus Most Significant bits of required delay Byte 3 should be 127 (80H) Byte 4 should be 127 (80H) plus machine number (from 1 up to 15) The second command includes the less significant bits as described previously for command 22.
Kramer Protocol 2000 12 Kramer Protocol 20001 The VS-44HC 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.
Kramer Protocol 2000 Table 18: Instruction Codes for Protocol 2000 Note: All values in the table are decimal, unless otherwise stated.

Kramer Protocol 2000 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.
Kramer Protocol 2000 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. NOTE 19 – After this instruction is sent, the unit will respond to the ASCII command set defined by the OUTPUT byte.
