    Switches for adjustment of shutter time, video gain and laser intensity. All adjustments are done in the configuration software and permanently stored in a electrically erasable EPROM. For software engineers, writing their own applications, MEL deploys examples with source-code in C++. For documentation of hardware registers, scanner implementation and data format see Data format and interface description.

  • Page 8: Calculation Of Shutter Time

    M2D-Laser-Scanner with Ethernet-Interface Manual The camera creates approximately 103 profiles per second. This corresponds to 9.71 msec period. The maximum shutter time is shorter than 9.71 msec, because of the minimum erase time interval. Maximum shutter time = 9.71 msec * 256 / 286 = 8.69 msec This maximum shutter time value is divided in 16384 steps.

  • Page 12: Dhcp

    M2D-Laser-Scanner with Ethernet-Interface Manual DHCP (dynamic host controlled IP numbering) is not supported. When DHCP is working in your network, restrict DHCP addresses, so that no device can take over an IP address reserved for the scanners. The scanner electronic does not react on DHCP request nor does it send DHCP request. The ping command can be sent from any PC in the network to verify, if the network operates, and if the target is available for the network (“connected”).

  • Page 34: Setting The Ip-Address By Software

    When the Reset-IP-Pin is released from ground, new working IP address will be set valid. Please note: Set the working IP address with the MEL demo and configuration software Rev. 2.4.0.2 or higher. Use Tab 11 for set up of the working-IP address, alternatively use the Web-Browser (with firmware 1.10.6 or higher).

  • Page 35: Ports

    Ports are a part of the IP-address definition. When setting the working IP address, the port is defined accordingly. As a factory default setting at MEL, we always use port : 3000. You can use “any” port, you should consider, that some services use ports: Internet (http) = port : 80.

  • Page 36: Ethernet Winsock Implementation

    M2D-Laser-Scanner with Ethernet-Interface Manual To communicate with a M2D Ethernet–Scanner so called Windows Socket „WinSock“-functions are used. These functions are part of all windows operating systems. Other operating systems provide similar functions. „WinSock”-functions are encapsulated into a „ws2_32.dll“-file. These files belong to Windows. The communication uses a TCP/IP-protocol with M2D Scanner working as a server.
