No communication through network; Signs IP address is not compatible with network
Potential Symptoms
- Unable to communicate to the display through the customer's network / Unable to communicate after recently replacing network equipment/router.
- Unable to publish or send messages.
- Connect failed error on Venus 1500 home tab (V4).
- Unable to open communication error -12 (V3).
- Unable to auto-detect display in the SW.
- Cannot ping display.
- IP address on sign is not similar to the IP assigned to the computer.
- Changed IP scheme, no longer able to connect to display/no communication.
- Customer has recently changed Internet Service Providers, network router, or ISP modem.
- Control computer uses a dock, and switches between wireless and wired connections to local network.
Environment
- Product Family: Message Displays
- Product: Galaxy, GalaxyPro, Electronic Message Center (EMC) or Board (EMB), Marquee, Readerboard
- Component: Ethernet based communication through a network, Controller network settings, IP addressing
- Control System: Venus 1500 v4
Cause
- Sign controller's addressing scheme is not compatible with the network.
- A network change may have occurred / New IP scheme implemented / Network has changed IP ranges, Subnet mask, or Default Gateway.
- Site has multiple networks available and computer is not currently connected to the correct network for the sign connection.
- Controller may have been changed and the IP settings were left on the default IP settings.
- Control computer switches between wired and wireless network, these networks are not on the same subnet.
Resolution
- Set the IP on the display controller to a supported IP for the network scheme. This may require a direct Ethernet connection to the display, see info regarding adding a secondary in the Temporary Operation below
- Galaxy Displays: Follow Galaxy: How do I change a static IP address on a display?
- GalaxyPro Revolutions: Follow GalaxyPro: How to set the IP configuration on a GalaxyPro Revolution (GPR) display?
- GP3, GP4, GPx Displays: Follow Galaxy: How do I change the IP address settings on a message center?
- Plug cable from computer to network(router, switch) that is now connected to the sign.
For Temporary Operation
If the display connected to the network equipment we can attempt to add a secondary to establish a connection to the display. If a connection is established we can then take time and configure the display to an IP compatible with the customers network.
- Add a secondary IP address to the Local Area Connection under Network Connections within the subnet of the display. See "How to add a secondary IP address to a computer", DD2059662.
- This will allow you to tunnel through the network and communicate to the display.
- To find the current IP on the display, either power cycle the display or check the Venus 1500 software for the old IP: "How do I find/change the IP address in the Venus 1500 v4 software?", DD2271372.
Note: On LARGER networks (i.e. multi-router setups or subnets using less then 24 bits for the subnet mask (e.g. 255.255.0.0) , it will likely be necessary to bypass the network and connect directly to the Daktronics Ethernet-based communication equipment in order to change the IP address (i.e. the network tunnel method will not work). It is still worth the time and attempt adding a secondary.
Direct connecting to the display
- Bypass network and connect directly to communication equipment or directly to the display controller
- Install a USB to Ethernet adapter and bypass the network. See How do I set up a D-Link USB to Ethernet adaptor for a Message Center display?, DD1981123 for details.
- Daktronics recommends the Tripp Lite USB/Eth adapter (part# 0A-1327-1120)
