  • Open /private/etc/hosts and make sure you have right below the first listing:
  • whatever-hostname-you-copied-in-step2

Admin Console Hangs

  • If you have any of the following modules on your MAC (under System Preferences | Privacy/Security | Accessibility), you may experience Admin Console hang when editing text fields. This is especially the case when you try copy/paste:
    • BetterTouch App
    • Text Expander App
    • PopClip App
    • Moom Appp
  • Usually disabling these modules will fix the issue. For more information please checkout:

Front Panel LEDs/Lights

  • Boot up sequence:
    • Power, RX&TX, momentary blink of Memory/RX and TX, and then Power only
  • Error light and Memory light blinking simultaneously: ISY is not able to get on the network.Please ensure:
    • The Network jack on the back of ISY is connected to your router
    • The lights on the Network jack have one steady on and the other one blinking. If not, check cable and connectivity to the router
    • Your router provides DHCP
    • There are no other devices on the network with the same IP address (IP Conflict)
      • If you have configured your ISY to use DHCP, then you will have to search your network for devices that might be in the same DHCP range as your router is providing
      • If you have configured your ISY with a static IP address, and as long as you have a good backup, you can Factory Reset your ISY and then restore a good backup (File | Restore ISY). Once prompted to change the network settings, choose No
  • Only Error light blinking: ISY cannot communicate with the SD Card. Please ensure:
    • The micro SD Card (on the front) is seated properly. Unplug ISY, remove the rubber cap, using a sharp object, push the micro SD Card in so that it pops out. Push it back in so it clicks in. Apply power to ISY
    • If reseating the micro SD Card does not work, you probably have a defective SD Card. Please consult Replacing/Formatting SD Card

Userid/Password dialog keeps popping up

This is usually related to firewall software on your computer. Two solutions:

Admin Console Closes Automatically

This is usually related to firewall software on your computer and especially with AVAST or AVG (including MAC). Two solutions:

Admin Console Minimized/Invisible and Cannot be Restored

This is usually related Admin Console state files not being updated properly and especially in case of multi monitors. All you need to do is to find the following files in Java temp directory (on Windows: c:\Users\[Username]\AppData\Local\Temp) and delete them. Or, you can simply search the computer for udi_*.* file patterns:

  • udi_tree.state
  • udi_frame.state
  • udi_pgm.state
  • udi_finder.state

DNS Error

The most likely error is due to ISY having a static IP address and the router blocking DNS from IPs not generated by DHCP server. If you have configured ISY with a static IP address, please consider

  • Reverting to DHCP, Or
  • Use for the DNS server

In case of using DHCP, you may consider using DHCP Reservation in the router such that ISY is always given the same IP address.
