3.3. Maximum cable length
The maximum cable length for an RS-232 connection is per definition 15m. Longer distances can be installed depending on
the environmental conditions of the installation site. It is up to the installer / user to secure a proper installation of the RS-
232 connection.
4. MIDI connection
Via the MIDI bus system several routers and control panels can be interconnected. The standard MIDI interface is used on all
Network MIDI control ports. For interconnection between the devices a standard MIDI cable with 5pin DIN connector on
both ends is used. The Network MIDI bus system allows connection of up to 16 routers with different addresses on the same
bus. Routers which are defined to work married, e. g. 2 routers as Audio follow Video or 3 routers as RGB (YUV) must be set
on the same address. Control panels dedicated to work with a specific router must have the same address as the router.
Several panels can work together with one specific router. Up to 16 single routers or combinations of routers can be
controlled from one i-Control control screen. The MIDI bus system and all RS-232 ports interchange the system status.
4.1. Several routers in one system
The Network MIDI bus system allows the interconnection of up to 16 routers with different addresses in one system. A
combination of routers working married counts as one address. This might for example be 1 audio router + 1 video router
working as an audio follow video system or 3 video routers working as a RGB (YUV) system. The routers in such a
constellation have to have the same address.
4.2. Connecting control panels
To get a control panel working with a specific router, give the control panel the same address as the router. Several panels
can be addressed to the same router. The X-Y panels can control 2 layers with breakaway function. If it is necessary to
control more layers with breakaway an additional panel must be used.
Panels can also be connected to a router via the RS-
232 interface. Please refer to your control panel manual for installation. Attention: Only NTW-32-Pro panels can be
used together with NTW-VD3232 when connecting via RS-232.
