[h][ac][sop][crc][id][som][command]
4 示例：" 打开" 命令（首先发送低字节）
→0×be, 0×ef, 0×10, 0×05, 0×00, 0×c6, 0×ff, 0×11, 0×11, 0×01, 0×00, 0×01
标头"be ef"
地址代码"10" ==] pt_oem
有效负载大小"05 00"==] 从wmsgid 到末尾
crc "c6 ff" ==] 如果crc 值为"c6 （低字节） ff （高字节） "
msgid "11 11"
msgsize "01 00"==] 从wmsgid 到末尾
命令"01"==]" 打开" 命令
5 投影仪响应信息表：
0×00: 成功
0×01: 无效命令（在控制命令列表但是无效。例如：没有读卡器插入时的读卡器命令）
0×02: 错误命令（包含crc 错误和未知命令）。
0×03: 系统状态-- 投影仪打开（正常模式）。
nack: 系统状态-- 投影仪关闭（待命模式）。
当投影仪处于待命模式时，投影仪会发出非确认(nack) 响应。
6 投影仪响应灯泡小时数：
字节0，字节1，字节2，字节3
字节0: 0×00 ( 成功)
字节1: 0×2f ( 灯泡小时数的标头)
字节2: lsb (hex)
字节3: msb (hex)
示例：800 (3×256＋2×16＝800) 小时→ 0×00, 0×2f, 0×20, 0×03
7 固件版响应：
固件版：4 字节ascii 代码"v*.*"
v: 版本
*: 0-9
8 示例： 版本1.5 → "v1.5" → 0×00, 0×30, 0×56, 0×31, 0×2e, 0×35 ( 成功，固件版标头， 4 字节ascii 代码： "v*.*")

如果两个输入源合成后超出定标器带宽，则投影仪将显示黑色图像。
