Hi Please help me
I am trying to find the decrete inputs codes fro my Dell w1900 TV. I need to change between the Svideo input and the VGA inputs. I can't find out how to generate these codes and the remote control that comes with the w1900 has an input button with a long menu that requires many key presses to change input channels.

I am not even sure if it is possible? please can you help all I have to go on is this datasheet I found... below

Thanks

Johnathan

Dell Televsion Remote Control Codes

4 STRATOSPHERE CODE SET
�� Based on Philips’ RC6 Infrared protocol.
�� Covers televisions and remote controls beginning with W2600, W1900, W4200
�� This code set may only be used to control receiving devices made by Dell
�� This code set must be referred to as a Dell code set in all documentation
4.1 Carrier Frequency
The transmissions use a carrier frequency of 36 kHz.
4.2 IR Remote Control Timing Diagrams
This section specifies the timing of pulses in the IR transmission. The key held method is
separate repeat packets.
4.2.1 Packet Structure
The packet structure is defined below:
t= 0.4444
Single Frame
Header customer code Device Type+parity command code Signal free time
half symbol times 20 32 16 16 6
time in mS 8.888 14.2208 7.1104 7.1104 2.6664
Header, and field content MSB's are transmitted first
240 t
Frame repetition rate:
106.656 mS
Frame repetition rate is from the start of the leading packet to the start of the next
packet. The Frame shall be repeated at this rate as long as the associated remote
button is held down. (up to the unit's time out limit)
4.2.2 Header Pulse Timing
The packet header structure is defined below:
half symbol time: t= 0.44444 mS
Mode: OEM
Trailer meaning: Not Defined (left as zero)
Header definition
Leader Start bit Mb2 Mb1 Mb0 Trailer
Symbol times 6tH+2tL 1tH+1tL 1tH+1tL 1tH+1tL 1tL+1tH 2tL+2tH
Symbol --- 1 1 1 0 0
Hex 6
Time increases moving right (leader is transmitted first.)

4.3 Customer code
The customer code immediately follows the header
Customer Code: 0x801C
MSb LSb
Customer Code
Binary 1 0 0 0 0 0 0 0 0 0 0 1 1 1 0 0
Hex 8 0 1 C
4.4 Device type and parity field
Device type and parity info are transmitted as described below.
The device type for the Stratos remote is defined as 0x00: Advanced TV
The MSb (first bit transmitted) is a toggle bit
In OEM mode the fields after header and customer code are customer
definable. Here we define a field to be called the Device Type. This field
identifies the specific device (for example, a television) to which the
command code applies. The device type allows multiple but different
products from the same manufacturer to utilize a common command code
set, and still maintain individual device control. This definition allows for
up to 127 possible device definitions. The Toggle bit is "toggled" each
time a new button press is made. This provides a determination if a new
button press was made when signal drop out due to shadowing or fringe
reception is occurring. The Toggle bit is transmitted first. The Device
Type code follows the toggle bit, MSb first.

Enter Key

Hi DBloch

Thanks for your post, but I am not totally clear what you are saying.

If I take the orginal remote and press "input" then say "9" then "enter" then it does not change the input. I have tried other numbers instead of 9 with no luck.

Any ideas?

Thanks for your help

Hi to everybody

can you help me please?

I've try to use the information 4 STRATOSPHERE CODE SET related to IR remote controller of TV Dell W1900, and all the information related standard key of Dell remote control are correct, and every comand listed above function correctly, except command to select single inputs, like as
DVI
XGA
AV2 (SVIDEO)

do you know why?

and I wolud like use direct command for switch between double inputs, in POP1 view mode, like as

POP1 mode (Picture Out Picture) big XGA - small Y/C
POP1 mode (Picture Out Picture) big Y/C - small XGA
POP1 mode (Picture Out Picture) big DVI - small Y/C
POP1 mode (Picture Out Picture) big Y/C - small DVI

do you know whitch are the single commands to select theese double inputs?

or in alternative do you know if exist the possibily of enter in a special service menù,
using sytandard infrared commander (menù + special number), to obtain this functionality?

do you know if exist another possibilities of command the monitor Dell W1900 with any other serial interface, to command the TV from PC?
for example using the data interchange pin of SCART connector?

thank you in advance
