Instruction definition for specific instruction note 29
Kramer protocol 29
Note all values in the table are decimal unless otherwise stated 29
Notes on the above table note 1 when the master switcher is reset e g when it is turned on the reset code is sent to the pc if this code is sent to the switchers it will reset according to the present power down settings note 2 these are bi directional definitions that is if the switcher receives the code it will perform the instruction and if the instruction is performed due to a keystroke operation on the front panel then these codes are sent for example if the hex code 01 85 88 83 was sent from the pc then the switcher machine 3 will switch input 5 to output 8 if the user switched input 1 to output 7 via the front panel keypad then the switcher will send hex codes 41 81 87 83 to the pc 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 was sent except for the first byte where the destination bit is set high note 3 setup 0 is the present setting setup 1 and higher a 29
