CoCon NEXT

CoCon NEXT is the next generation of CoCon network extenders which have the same functionality and connectivity, but additionally offer the option to configure (via DIP switches) a delayed power up of the conference extension ports (see DIP switch table below).

Two CoCon network conference ports (uplink).
1. Gives CoCon network signal to conference extension ports of the central engine or other network extender.
2. Allows connection in branch / loop.
LAN ports are not used.
48 V power supply: powers the four conference ports.
Four CoCon network conference ports (downlink).
DIP switches enable / disable power of conference ports and allow sequential startup.

General Network Extender Guidelines

The maximum distance between the central unit and the first CoCon network extender or delegate unit in the branch is 100 m.
The maximum distance between two CoCon network extenders is 100 m.
The CoCon network extender must be powered externally (through power supply of CoCon MME or CoCon power supply).
One branch or loop cannot consist out of more than 8 CoCon network extenders (for optimized packet propagation)
One branch or loop may consist of no more than 20 Plixus devices (less if power is limiting factor).
Restrict a downlink port branch to 1 network speed: 100 Mbit or 1 Gbit!

Redundancy

In CoCon it is possible to insert a type of fail-safe mechanism by creating redundancy. You can get redundancy by inserting loops in your network. When there is a loop, CoCon can still access the device using a different route when a cable or a device in one side of the loop breaks.
