On the M1XEP Ethernet Module you should be able to have up to 30 non encrypted connections like local touchscreens and computers and up to 5 encrypted connections at once. As more connections are made, the response time will slow slightly.
This is especially important if multiple touchscreens are online in a home or if multiple PCs are running software like ELKRM Remote Management.
You can test the connections by running multiple instances of ELKRM on a PC screen. As the screen changes on one instance all the other screens will change.
Remember: When ELKRP software is running, all other connections are put on hold. When ELKRP disconnects, the other connections will come back up after a few seconds.
