Important Notice

PALUNII is not backward compatible with first generation PALUN.

Introduction

PALUNII is a PoE-powered Video Balun which can transmit both power and

digital IP video signal over coaxial cable. With PALUNII, you can easily upgrade

the surveillance system from analog to IP, leveraging the existing coaxial

infrastructure without re-cabling.

PALUNII supports connecting with PoE devices, allows flexible usage of

networking products. Moreover, a smart switch design enables PALUNII to

better accommodate PoE devices of different class levels. Please see all the

detail information in this document.

How to Use the Switch on PALUNII (TX)? The switch on PALUNII TX (the green one only) is only functional when connecting to a PoE device at the RX end. The switch is designed for adjusting the power output from the PoE switch in order to better accommodate PoE devices of different class levels.

Now, if you switch PALUNII to C1+ (for Class 1~4 PoE device only), it will help to increase the guaranteed power output from the PoE switch by advertising a higher class level. Therefore, in our example above, even though the IP camera is Class 1, PALUNII will advertise it as Class 2 to the PoE switch so that the PoE switch will reserve a Class 2 guaranteed power (7W) for devices connected to this port. Then, it is now sufficient to power up both PoE device and PALUNII.
