The projector uses a challenge response type authentication with an MD5 (Message Digest 5) algorithm. When the projector is using a LAN, a random 8 bytes will be returned if authentication is enabled. Bind this received 8 bytes and the authentication password and digest this data with the MD5 algorithm and add this in front of the commands to send.Following is a sample if the authentication password is set to “password” and the random 8 bytes are “a572f60c”.1) Select the projector.2) Receive the random 8 bytes “a572f60c” from the projector.3) B ind the random 8 bytes “a572f60c” and the authentication password“password” and it becomes “a572f60cpassword”.4) D igest this bind “a572f60cpassword” with MD5 algorithm.It will be “e3d97429adffa11bce1f7275813d4bde”.5) A dd this “e3d97429adffa11bce1f7275813d4bde” in front of the commands andsend the data.Send “e3d97429adffa11bce1f7275813d4bde”+command.6) W hen the sending data is correct, the command will be performed and thereply data will be returned. Otherwise, an authentication error will be returned.NOTE• As for the transmission of the second or subsequent commands, the authentication data can be omitted when the same connection.munications settingSet the same communication settings (selecting from options below) on theCONTROL terminal for transmitting and receiving side connected with a RS-232C cable.Baud rate: 4800 / 9600 / 19200 / 38400 bps Parity NONE / ODD / EVEN Data bit: 8 bit (fixed)Start bit: 1 bit (fixed)Stop bit: 1 bit (fixed)mans available only for daisy chain communicationThe projector supports the following commands only for daisy chain.(1) Control the projector (Set/Increment/Decrement/Execute)(2) Get the projector’s status (Get)(3) Get the number of connected projectors(4) Set the communication Group identification and Communication ID.(5) Get the communication Group identification and Communication ID.mand formatProtocolConsist of header data (7 bytes) + command data (6 bytes)HeaderBE + EF + Packet_Type + 06 + Group + ID + Checksum Data chartSupport Command Packet_TypeGroup ID Control the projector‘83H’0~160~64Get the projector’s status‘83H’1~161~64Get the number of connected projectors ‘84H’00Set the communication Groupidentification and Communication ID ‘85H’1~161~64Get the communication Groupidentification and Communication ID‘86H’CONTROL OUT port in Projector CONTROL IN port in ProjectorRS-232C cable (Cross)- (1) (1) CD RD (2) (2) RD TD (3) (3) TD - (4) (4) DTR GND (5)(5) GND - (6) (6) DSR RTS (7) (7) RTS CTS (8)(8) DTS- (9)(9) RICalculation of ChecksumSum up all of 12 bytes except the Checksum, then make the bit inversion of the lowest byte of the total, and add 1 to the inverted byte.

投影机投影仪技术与参数一、投影机技术：1.LCD（液晶显示）技术：这是目前应用最广泛的一种投影机技术。
它使用三块液晶面板，通过控制光的透过率来形成图像。
液晶投影机具有较高的亮度和对比度，但对黑色的表现相对较差。
2.DLP（数字微型镜面）技术：DLP投影机采用微型镜面阵列和彩色滤色器来生成图像。
它的优点包括高对比度、快速响应和颜色饱和度高。
DLP投影机适用于高亮度场景，如商业演示和电影院。
3.LCoS（液晶晶体硅）技术：LCoS投影机结合了LCD和DLP的优点，具有较高的对比度和颜色饱和度，适用于家庭影院和专业应用。
二、投影机参数：1.分辨率：投影机的分辨率表示图像的清晰度。
常见的分辨率包括XGA（1024x768像素）、WXGA（1280x800像素）、1080p（1920x1080像素）等。
分辨率越高，图像越清晰。
2. 亮度：投影机的亮度通常以流明（lumen）为单位。
亮度决定了投影机在不同光线条件下的表现。
一般来说，商业和教育用途需要较高亮度，而家庭影院则可适当降低亮度。
3.对比度：对比度表示了投影机图像中黑色和白色的差异程度。
对比度越高，图像越清晰，黑白分明。
4.投影尺寸和投射距离：投影尺寸是指投影机能够在屏幕上显示的图像大小。
投射距离是指投影机与屏幕之间的距离。
根据投影机的不同，投影尺寸和投射距离也会有所变化。
5.校正功能：一些投影机具有梯形校正和镜头移动功能，可以根据投影机与屏幕的位置和角度进行校正，以获得更好的投影效果。
6.接口和兼容性：投影机通常具有多种输入接口，如HDMI、VGA、USB等，以便连接不同类型的设备。
兼容性则表示投影机是否能够适配不同的视频格式和分辨率。
以上是投影机常见的技术和参数介绍。
在选择投影机时，可以根据具体的应用场景和需求来选购适合的型号。
同时，也建议在购买前参考产品的性能测试和用户评价，以便更好地了解和判断该款投影机是否符合自己的需求。
