Share Mode
Share Mode
Share Mode allows multiple users to share the audio and video of a target computer over the
network and arbitrate for control of that computer. Share Mode is intended for use in either
Extender Mode or Desktop Mode.
Using a USB device with Share Mode
Only the first user station connected to a target is allowed to use a vUSB or vMedia device (other
than the keyboard and mouse).
Keyboard and mouse control during Share Mode
Initially, the first user (User A) to log onto a server has keyboard and mouse control. Subsequent
users that log on can access video and audio. However, until User A relinquishes control, no
subsequent users have keyboard and mouse control.
If User A does not move the mouse or type on the keyboard for more than one second, control may
be relinquished. User B can obtain control by typing or moving the mouse.
Audio and video quality
Share Mode does not affect sound or video quality to any connected user.
Configuration
Share Mode can be configured from the HMX Manager, or when in Extender Mode it can be
configured from the serial menu.
Switch requirements
Share Mode connected transmitters send out multicast IP packets to the Ethernet switch. If the
switch used is a non-IGMP capable switch, the switch will broadcast the multicast packets to every
port on the switch. Other non-HMX Manager devices connected to the switch may not be able to
tolerate the traffic rate of the broadcast packets. In this case, either a dedicated switch or an IGMP
capable switch should be used for the HMX system.
