Overview 3 Overview The Kramer VS-88HC is a matrix switcher designed for high quality home entertainment. It is a true 8x8 matrix switcher for HDTV compatible, component video (Y, Pb/Cb, Pr/Cr), digital audio (S/PDIF) and analog unbalanced stereo audio signals, letting you simultaneously route any of the eight inputs to any or all of the eight outputs. The component video, S/PDIF and analog audio signals are on RCA connectors.

Kramer Protocol 2000 12 Kramer Protocol 20001 The VS-88HC is compatible with Kramer’s Protocol 2000 (version 0.48) (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 4B 80 81 85 NOTE 5 – For the OUTPUT byte set as 6, the VIS source is the input selected using the OUTPUT byte. Similarly, for the OUTPUT byte set as 7, the VIS source is the output selected using the OUTPUT byte. Note also, that on some machines the sync source is not software selectable, but is selected using switches, jumpers, etc! 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.
Kramer Protocol 2000 For example, to set for 350ms blanking time (14 steps), send HEX codes 07 8E A0 81 NOTE 18 – Delayed execution allows switching after a delay dictated by RS-232. To do this, the user sends instruction 7 with the “ Set for delayed switch” option (64dec) before sending the switch command (instruction 1) or pressing via front panel. The switch is not executed (unless timed-out) until the “ Execute delayed switch” code is sent, or the “ Set for delayed switch” code is sent again.
