RS-232 PROTOCOL

9600 Baud

8 bits

No parity

1 Stop bit

ASCII

RxD of the PC or TxD of the VHD is on pin2

TxD of the PC or RxD of the VHD is on pin3

Gnd is pin 5

RTS of the PC or CTS of the VHD is on pin7 (not used)

CTS of the PC or RTS of the VHD in on pin8 (not used)

Command format <input><aspect ratio>

Inputs: Aspect Ratios: Power:

0 = Composite A = Anamorphic ON = Power on

1 = S-Video L = LetterBox OF = Power off

2 = Component S = Standard (4:3)

3 = Pass Through C = Computer (for Pass-Through)

R = RGB HDTV (for Pass-Through)

Y = YUV HDTV (for Pass-Through)

To keep the currently selected aspect ratio or input, replace the letter/number with a dash "-"

Each command must be followed by a carriage return <CR>.

Examples:

2L will select the component input and change the aspect ratio to letterbox

-A will change the aspect ratio to anamorphic, but leave the input selection alone

1- will change the input to S-Video, but leave the aspect ratio alone

RS-232 Projector Control requires a cable terminated with male RJ-11 jacks at both ends.

Wiring is the same as for a phone (ie. in a cross configuration).
