Device communication problems

Steps to undertake:

• Check the internet connection of the MidTeQ PULSE EMS. Check with your computer if you have internet on the ethernet cable attached to the MidTeQ PULSE EMS.
• Try scanning on the local network for the MidTeQ PULSE EMS with an IP scanner (see also "Accessing the commissioning interface").
• Check with the building owner (residential) or network administrator (commercial) if this is a network with fixed IP addresses. The MidTeQ PULSE EMS is by default configured to use DHCP. If you need to change it to a fixed IP address, first connect it to a DHCP network, and change the IP address from there to the necessary fixed IP address.
• Check if communication over the right outbound network ports is allowed. (See also "Firewall guidelines")
• Verify if the Ethernet wiring guidelines have been followed.
• If the MidTeQ PULSE EMS is on a 4G connection:
  • Check the 4G reception of the router. (Note, it can be on another mobile network than your phone).
  • Place the router or 4G antenna on another location.
  • Check if there is enough data in the 4G connection bundle. It is recommended to have 5GB/month available for up to three devices, plus 500Mb per additional device

• Check if the MidTeQ PULSE EMS is claimed in the app. See linking the MidTeQ PULSE EMS to your account
• Check if the account with which you try to login has access rights for the MidTeQ PULSE EMS. See user management
• If the MidTeQ PULSE EMS is not online, and you don't know the password for local login: contact your distributor to obtain the recovery password.

If you know the fixed IP address:
Configure your computer to have a fixed IP address in the same subnet (but on a different address) than the MidTeQ PULSE EMS. Connect your computer directly with an ethernet cable to the MidTeQ PULSE EMS. Do not use a switch or router. In a webbrowser, surf to the fixed IP address of the MidTeQ PULSE EMS. You should now be able to access the MidTeQ PULSE EMS.

If you do not know the fixed IP address:

• You can retrieve the IP address through mDNS. See also Option 3.2 of Accessing the commissioning interface.
• Or reset the MidTeQ PULSE EMS.

Steps to undertake:

• Check the network connection of the device. Check with your computer if you have internet on the ethernet cable attached to the device.
• Try scanning on the local network for the device with an IP scanner. (see also "Accessing the commissioning interface").
• Check with the building owner (residential) or network administrator (commercial) if this is a network with fixed IP addresses and if the device has the right IP address set.
• Check if the MidTeQ PULSE EMS and the device are in the same subnet (e.g. a MidTeQ PULSE EMS in subnet 192.168.1.x can generally not talk with a device in subnet 192.168.200.x).
• Verify if the Ethernet wiring guidelines have been followed.
• If you use a VLAN, make sure the device you want to add is in the same VLAN as the MidTeQ PULSE EMS.

Steps to undertake:

• Check if remote communication and control have to be enabled on the device. See the specific device configuration page for more information.

Steps to undertake:

• Check if the MidTeQ PULSE EMS is online.
• Check if the device is still online on your network.
• Make sure if the device uses WiFi that it has good WiFi reception and that the WiFi password is up to date.
• If the MidTeQ PULSE EMS is on a 4G connection:
  • Check the 4G reception of the router. (Note, it can be on another mobile network than your phone).
  • Place the router or 4G antenna on another location.
  • Check if there is enough data in the 4G connection bundle. It is recommended to have 5GB/month available for up to three devices, plus 500Mb per additional device

Steps to undertake:

• Check if each device on the serial bus has a unique address. See the specific device configuration page for more information.
• Check if the wiring polarity is correct. See the specific device configuration page for more information.
• Verify if the RS485 wiring guidelines have been followed.
• Check if remote communication and control have to be enabled on the device. See the specific device configuration page for more information.
• Check if the device addresses are set to high values. Some devices default to e.g. address 255, while the MidTeQ PULSE EMS starts searching from 1 - so it can take a while before the device is found.

Steps to undertake:

• Check if each device on the serial bus has a unique address. See the specific device configuration page for more information.
• Check if the wiring polarity is correct. See the specific device configuration page for more information.
• Verify if the RS485 wiring guidelines have been followed.
• Check if remote communication and control have to be enabled on the device. See the specific device configuration page for more information.
• Check if the device addresses are set to high values. Some devices default to e.g. address 255, while the MidTeQ PULSE EMS starts searching from 1 - so it can take a while before the device is found.

Steps to undertake:

• Check for loose wiring.
• If the MidTeQ PULSE EMS is on a 4G connection:
  • Check the 4G reception of the router. (Note, it can be on another mobile network than your phone).
  • Place the router or 4G antenna on another location.
  • Check if there is enough data in the 4G connection bundle. It is recommended to have 5GB/month available for up to three devices, plus 500Mb per additional device

Steps to undertake:

• Check if this error persists after rebooting the controller.

Steps to undertake:

• Check on the digital meter if the cable is in P1 and not connected to the similar S1 port.
• Is the USB connection on the controller inserted all the way.

Steps to undertake:

• Check if this error persists after rebooting the controller.
