Uniclass DX120 - Pre-Installation Guide; Gigabit Ethernet Switch Requirements

16
Pre-Installation
Before you install the KVM Matrix over IP Extender System, you should have these items on the checklist
ready:
• Plan the layout path and deploy the UTP cable for extension.
• Plan the path through which the CAT5E UTP cable (or higher category network cable) will be deployed
across the distance between the Transmitters and the Receivers. You should choose the layout path not
only based on shortest possible length consideration, but also on least electromagnetic interference.
• It’s strongly recommended to shorten your Cat5x cable than 100m if the network architecture contains
the equipment such as RJ45 extender adapter, otherwise, the signal may be declined.
Notes:
1. Use good quality CAT5E cable can be produced the better video outcome with longer distance span.
2. To choose the path of the CAT5E UTP cable should not only take into account the shortest possible
path, but also consider keeping out from any significant electromagnetic interference source.
3. The ideal location for the power outlets near where you located the extenders.
Requirement of Gigabit Ethernet Switch
• When grouping these units of Transmitter and Receiver, a Gigabit Ethernet Hub/Switch is necessary
due to the requirement of bandwidth. To ensure the better quality of transmission, a reputable name
brand hub/switch is recommended.
• Some features of Gigabit Ethernet Switch/HUB are required, for example, IGMP Snooping, Multicast
Filtering and Jumbo Frame, other specs like IGMP Querier, IGMP v2 and IGMP Fast Leave are strongly
recommended. If more than one transmitter connects to the same network segment without support
of IGMP Querier by Switch/Hub, the Extender System may work incorrectly. The images below are
examples of the settings, for more setting details, please refer to the Hub/Switch's instruction manual.
IGMP Snooping
Jumbo Frame
Multicast Filtering
• Make sure you have enough available bandwidth between switches if the Network you connected is a
cascading architecture, otherwise, the quality of stream video may poor.
