Runco V-63HD 用户手册

The DHD Controller accepts commands in the form of IR signals that conform to the 
Phillips RC5 protocol. Each DHD Controller remote control button has an RC5 control 
code associated with it. 

You can use these codes to program a third-party, “universal” remote control unit to work 
with the DHD Controller. These third-party products usually come with a computer 
software application for this purpose. For more information, consult the documentation 
provided with the remote control unit. 

The IR control codes have the following characteristics:

• Each code consists of 14 bits:

• Two (2) start bits (always 1);

• A toggle bit. This bit is inverted every time a key is released and pressed again. This 

allows the DHD Controller to distinguish between a button that remains down and 
one that is pressed repeatedly.

• Five (5) address bits. The default address is 17 (binary 10001). To change it, select 

Remote Code from the Miscellaneous menu (in the Service menu) and follow the 
steps given on page 53. 

• Six (6) data bits. 

• The carrier frequency is 36 kHz, with the modulated pulses having a 25% duty cycle. 

• Commands are sent at a maximum rate of 9 Hz.

The following serial commands are meant to emulate buttons on the remote control. Each button 
has its own serial command, so effectively it is as if you were using the IR remote only you’ll be 
doing so via serial commands. These commands provide active OSD responses just like the IR 
remote.
