RS 232 Protocols
Package Format :
00 FE CH_ID[4X] CMD[6X­DF] Param0~ParamN[3X] CRCH[5X] CRCL[5X] FF
CH_ID : PC=40~47, 40=Current Camera, 41=CAM1, 42=CAM2
Panel=48~4F, 48=Current Camera, 49=CAM1, 4A=CAM2
Param Data Types :
hex : 1­byte [3X] means X=0~Fh
int2 : 2­bytes [3X 3Y] means XYh (signed)
uint2 : 2­bytes [3X 3Y] means XYh (unsigned)
int3 : 3­bytes [3X 3Y 3Z] means XYZh
hex4 : 4 hex for version N.NNN
hex6 : 6 hex for date YYMMDD
str2N : N*2 bytes, MSB first ASCII * N
CRCH/L = 8­bit CRC for error protection, generated by lookup table from (CH_ID / CMD / Param0~ParamN)
