APPENDIX B
Controlling
Digital Magic
(Model # KD-DH12)
from your Home Theater Automation System
For integration with your existing equipment, your Digital Magic unit can be conveniently controlled from your existing Home Theater Automation
System (like Crestron, AMX, or CNMSX-Pro) by using the discrete command protocol. You will need to locate the RS-232 port (D-sub, 9-pin female
connector) on the upper-left rear panel of your Digital Magic unit, and connect it to your Home Theater Automation System using a standard RS-
232-cable. You will be able to use your existing Home Theater Automation System to control the following Digital Magic functions:
Input select
Tuner channels Up and Down
Channel ##-# select
Aspect Ratio
Output resolution
Output format
Following is an example of how to use a communication program (such as Hyper Terminal) to generate the commands to control the above func-
tions of your Digital Magic unit using the discrete command protocol:
With your Digital Magic unit in the Power-OFF condition, use a straight RS-232 cable (not a null modem cable) to connect the RS-232 port of your
Digital Magic unit to the RS-232 port on your PC. Use the following settings:
Set the Hyper Terminal to COM1*
Baud Rate: 57600
Data: 8-bit
Parity: None
Stop: 1 bit
*Note: make sure you are not running any other active program using COM1, such as the “Hot Sync” Palm program
Turn ON the Power to your Digital Magic unit. In your Hyper Terminal window, press [ENTER]. You will be prompted with:
Key Digital Digital Magic RS-232 control
DH12>
The help menu and the rest of the commands should be very simple:
Input select
Tuner channel Up and Downs
Channel ##-# select
Aspect Ratio
Output resolution
Output format
Note that in RS-232 command mode, the Digital Magic Remote Control and front-panel Pushbuttons are non-functional.
If at any time you want to escape from the RS-232 command mode, type “exit” on your terminal and press [ENTER].
