Have now came to the conclusion that we are getting some kind of a signal interference all of a sudden. Swipes have been issue free for the last 6-7 months. Now all of a sudden we are having problems with swipes communicating with coordinator. Crypto sent a new coordinator and still did not solve the problem. We have done no new equipment installs or have not changed anything on site from when we installed the swipes 6-7 months ago. Does anyone have any suggestions or has had this problem? Im running out of ideas. Thanks in advance.
