Essential Checks Before Setup

The AngleID reader uses DHCP to obtain its initial settings. The AngleID Config Tool communicates with the reader by using DHCP protocol. It is therefore important to ensure that the reader's DHCP request does not get a response from a DHCP server on your network.

When the reader does not get a DHCP response, it shows a specific sequence of LED flashes. Therefore, to make sure that DHCP traffic is not being captured by a server on your network, you must check that you see this LED sequence before you configure the reader .

What you Should See Before Configuring the IP Address

The LED at the top left of the reader can show red, green or orange.

When the reader is powered up:

  1. The LED shows orange. It continues to show orange for roughly 40 seconds, and then goes out.
  2. The LED lights up red, and then goes out again.
  3. The LED shows a red-orange-red-orange error code.

You need to ensure that you get this LED sequence from the reader; if you do not get this sequence, then the installation process will not work.

Common Error Codes

If your network has a DHCP server that is responding to the reader, the most likely LED sequence that you may see is red-orange-red-green. This occurs if the reader has been sent a message from a DHCP server, but no other Ubisense products, for example the Ubisense DIMENSION4 RTLS, are installed. If DIMENSION4 is also installed, you might see other sequences, depending on its configuration.

DHCP Server Changes

If you do not see the red-orange-red-orange LED sequence, you must ensure that any DHCP server on the network is configured to ignore requests from your AngleID readers. All DHCP servers can be configured to ignore certain MAC addresses. You can find the MAC address of an AngleID reader written on a label next to the network socket. If it is not possible to stop the DHCP server from responding to the reader, then you will need to set up a separate network so that you can install the reader.
