Introduction

Connect Power to the U-Hub

Connect a power source to the U-Hub using an IEC cable and secure using the retaining clip.

Connect all input and Network cables.

Input cables should be balanced XLR using 3-core cable with a shield. Most signal processing and mixing products also use XLR
connections, so the cable can be a male to female XLR or "microphone" cable.
Network Connections should be made using ODU U-Net cables or adaptors available as accessories from Martin Audio.

IP Selection

The U-Hub can communicate over the ethernet network which has been configured for static or dynamic IP. The default is
dynamic IP where the network has a DHCP server to assign individual IP addresses to all nodes detected on the network. This is
extremely straightforward for a plug and play system which is why Domestic routers are configured to act as a DHCP server by
default. Static IP removes the requirement for a DHCP server on the network so is frequently the choice for more advanced
systems.
The U-Hub can be configured for Static IP, there are two methods to enable this. You will need to know the range for all other
products on the network and assign an IP address writhing the same range but with an address unique to the U-Hub.
You can select the default Static IP address by using the IP Reset switch on the front panel. Press and hold the switch for
approximately 3 seconds and the U-Hub will be set to Static IP with an address of 169.254.19.71. The default address gives you
the flexibility to connect to the U-Hub without having to adjust your PC LAN settings, if the PC is in dynamic mode it will self-
assign a link local address in the 169.254.xxx.xxx domain. If your network is configured for static mode, the U-Hub will be
immediately discoverable as long as your network is in the 169.254.xxx.xxx range and as long as there isn't another device with
the same IP. The principal intention of this mode is to give you immediate connection to the U-Hub, so you can change the IP to
a number of your choice
You can also change the IP mode via Vu-Net (See the Vu-Net chapter) using the right-click menu. Note that if you are in the
default dynamic mode and you change to a static IP address outside the 169.254.xxx.xxx range you will lose connection with the
U-Hub until you reconfigure your PC to static mode in the same range.
When the U-Hub has been set to static IP, either manually or using the default static IP mode, the Static IP front panel LED will
illuminate yellow.

IP Reset

If a U-Hub has been previously configured for static IP it can quickly be set to dynamic using the IP reset switch. The reset is a
recessed front panel switch a short press will return the U-Hub to dynamic IP configuration. It can then be discovered via Vu-Net
using Device Discovery, see the Vu-Net chapter for more details.
