Ethernet Communication FAQ of BX controllers

1. Ethernet communication FAQ for direct link mode of BX controller
(1) For XP system, if the local internet connection is “automatically obtain IP address”, then after connect with controller, it will point out “is obtaining internet address”. If you write parameters now, will fail, users need to wait about 1-5 minute, and when the local internet connection point out “this connection is limited or cannot connect”, you then write parameters;
(2) For XP system, when DHPC Client and DNS Client is not starting, write parameters will fail. Solution: My computer--management--service and application process--service; Find DHPC Client--attributes--start type automatically--application--start--OK; DNS Client--attributes--start type automatically--application--start--OK;
(3) For direct link, write parameters failed or send programs failed, it’s mainly on laptop. As there’s wireless network car and wire network card on the PC, may mix when automatically obtain IP. There are three methods to solve it:
1) Close or forbid wireless network (some of the PC need to restart the computer when close/forbid the network).
2) Change “automatically obtain IP address” to “manually select the below IP address”.
3) Change the local internet connection status--convention--attributes--internet(TCP/IP)--attributes--advance--IP setting, cancel “automatically hop count”, enter 2, add two gateway, one hop is 1, one hop is 2. Or users may be mixed by the IP address, then write parameters failed or send programs faild.
(4) For LedshowTW2012 V3.12.8.1, you enter passwords 888 to bind the screen number and IP, so, when the acture screen number is different with the one you set in software, write parameters will fail. You need to use at least LedshowTW2012 V3.12.10.10, users could solve it, no need to bind the screen number and IP address;
(5) The Ethernet line is EIA/TIA-568B or not. The color mark and arrangement should be seriously according to international principle.Standard 568B, from left to right: white orange, orange, white, green, blue, white blue, green, white brown, brown. Or the communication may not stable;
(6) For some PC, when write parameters success, and then send programs, point out “the storage is not enough”. It’s usually caused by the incomplete network card drive or the unmatched network card. Users could download a Driver Genius to match the network card. Or change “automatically obtain the IP address” to “manually select IP”.

2. Ethernet communication FAQ for fixed IP mode, single screen
(1) Write parameters failed, check the Ethernet line and power supply;
(2) Write parameters failed, check the controller IP data is correctly distributed;
(3) Users could connect controller IP on running, but write parameters failed. Please check the controller IP and port is consistent with the controller IP in software, if not, write parameters will fail;
(4) The controller IP and port is consistent with the controller IP in software, but the local internet connection does not choose it, will write parameters fail;
(5) When the network card is gigabit lan, please check network card speed and the duplex values is automatically detect. Local internet connect--convention--attributes--configuration--advance--connect spped and change the duplex values as automatically detect.

3. Ethernet communication FAQ for fixed IP mode, multi-screen
(1) Write parameters failed, check the Ethernet line and power supply;
(2) Write parameters failed, check the controller IP is valid;
(3) Start--Run, enter: ping+(space)+controller IP, check the controller IP is valid. If it’s ok, check the controller IP is not used by others.Then, close the controller power supply, do it again, if still ok, then, means the controller IP is used by others, users need to distribute another valid IP. After that, check the controller port is not forbidden;
(4) When users use fixed IP mode in local area network, the controller IP informations must be valid in the local area network. And set the Subnet mask, default gateway, also all the IP, port is allowed to enter. What’s more, if the IP address is bind with MAC address, users need to set MAC address.
