ASCII Protocol
The QuadraVista HDMI series supports the ASCII command prompt
interface. You can use HyperTerminal to control your QuadraVista HDMI
series. The RJ-45 port (IP) on the QuadraVista HDMI series can also be
used to interface with a third-party controller for control over IP. This chapter
familiarizes you with using the Rose Electronics ASCII Protocol (AAP) of the
QuadraVista HDMI series via Microsoft® Windows HyperTerminal function
as an example.
Entering the ASCII Z Command Interface
To startup the ASCII Z command interface, perform the following steps:
1. Make sure you have a binary file editing program installed in your
computer.
2. Run the binary file editing program and use the following command
syntax to create and save the sample binary file–
unsigned char 0x55,0xAA; //command head
unsigned char 0xF8,~0xF8;
//command ID
unsigned char strlen(prompt$)+
2,~(strlen(prompt$)+2);
//commandlength
unsigned char FunctionID; //must be 0x07
unsigned char prompt$[]; //must end by 0x00 !!!
unsigned char 0x00; //command tail
Using the below binary text string as an example–
0x55 0xAA 0xF8 0x07 0x0B 0xF4 0x07 “ZA 000000” 0x00
Execute “ZA 000000” = arranges all windows to its proper size and position
NOTE: The double-quote “” of sample string “ZA 000000” is just for string
expression, there are no quote characters (0x22) in the command
contents (actual memory dump of command).
