  If you see a 'Could not connect to the controller' message, no unit displays, or the display doesn't update after starting the Remote Access software, here are some things to check: * Make sure the access address is correct. Verify the address of the target Central Station EX and set the correct access address. * Check the LAN wiring between Central Station EX and the PC to ensure it's properly connected. * Confirm that settings for Central Station EX are completed by registering networks and monitoring targets. * Verify that the power of Central Station EX is turned on.
