Command code => A0h = CARD_RESET_PARA_CMD
Parameter #1 = > 30h=reset current parameter, 31h=reset all user
--- Answer ---
Parameter #1 = > 30h=reset current parameter, 31h=reset all user
*******************************************************
Command code => A2h = CARD_STORE_RECALL_CMD
Parameter #1 = > 30h=store, 31h=recall
Parameter #2 = > User No:: 31h~33h (3 users)
--- Answer ---
Parameter #1 = > 30h=store, 31h=recall
Parameter #2 = > User No.: 31h~33h (3 users)
Example: Set the SDI OUT aspect ratio flag to 16:9
The control data stream: F0h, 1Ch, 0Ah, 08h, 98h, 30h, 31h, 37h, 31h, FFh
F0h, ID(1Ch), length(0Ah), 08h, 01h, Command code(98h), para#1(30h), para2(31h),
CHECKSUM_L(37h), CHECKSUM_M(31h), FFh
Checksum=F0h+1Ch+0Ah+08h+98h+30h+31h=17h
The answer from SE900’s VOUT card: FCh, 1Ch, 0Ah, 08h, 92h, 30h, 31h, 33h, 32h, FFh
