Sharp, EIKI EIP projectors (Code 20 hex, absolute audio)
This family has many members with a range of channel messages.
Sharp has RS232 code charts at the back of the Operation Manual for each projector.
Channel codes are: |
|
|
Computer1 := 'IRGB | 1' + 0D; | // RGB 1 VGA |
Computer2 := 'IRGB | 2' + 0D; | // RGB 2 analog, sometimes DVI analog |
Computer3 := 'IRGB | 3' + 0D; | // DVI Analog |
Computer4 := 'IRGB | 4' + 0D; | // DVI Digital |
Video1 := 'IVED | 1' + 0D; | // Comp |
Video2 := 'IVED | 2' + 0D; | // |
Video3 := 'IVED | 3' + 0D; | // Comp Video 2 |
Video4 := 'IVED | 4' + 0D; | // |
Video5 := 'IVED | 5' + 0D; | // RGB/COMPONENT on SHARP |
Video6 := 'IVED | 6' + 0D; | // DIGITAL MODE on SHARP |
Video7 := 'ISEV | 1' + 0D; | // |
Video8 := 'ICMP | 1' + 0D; | // COMPONENT on EIKI_EIP_S200/X200/X350 |
Video9 := 'IDVI | 1' + 0D; | // DVI on EIKI_EIP_S200/X200/X350 |
Any one of these codes can be set into Constant:0/Constant:1 for computer codes and Constant:2/Constant:3 for video codes. (The default is to have Computer1 (above) as the “Computer” channel and Video1 as the “Video” channel. Setting OPT1 switch ON will swap Video1 and Video2 channels.)
•Some models use IVED 1 for Comp Video, and IVED2 for
•OPT7 handshake mode and power on panel connection blink codes available.
