HKE120-EH23(FAQ)

1：What is the difference between the new version of HKE120-EH23 and the old version?

A: The new version of HKE120-EH23 supports IGMP authentication. It is possible to utilize more TXs for many-to-many connections on IGMP network switches, and improves the video output stability during many-to-many connections

2：Can the new version of RX and the old version of TX, or the new version of TX and the old version of RX be used in combination?

A: Since the new version of HKE120-EH23 supports IGMP authentication and the old version does not support IGMP authentication, the new version of RX cannot receive the video signal from the old version of TX, and the new version of TX cannot send the video signal to the old version of RX. If you need to use them together.
