Grass Valley CR Series Quick Start v.3.2 - Manual (Page 7)

Product Number: QG0003-13 Revision: 3.2; Date: 02 Dec 14 7
CR Series Compact Routers
You can install button legends at this (or any) time. Button
legend templates are included on your CD. See Button Legends
on page 9.
Rack Mounting
Place the router (or router assembly) in the rack where you
want it, aligning the screw holes with holes in your rack
frame. Secure the router using your screws, nuts, and washers,
as required. See Figure 5.
Mount remote panel modules the same way.
For the 1RU routers (or remote panel modules), the mounting
holes are spaced 1.25″ (31.75mm) vertically and allow
approximately 1/8″ (3mm) of play horizontally.
For the 2RU routers (or remote panel modules), the 3 mount-
ing holes on each side are spaced 1.25″ (31.75mm) and 1.75″
(44.45 mm) (overall, 3.0″or 76.2 mm) vertically and also
allow approximately 1/8″ (3mm) of play horizontally.
 Because the routers are small, you might not have enough space
to reach behind the router and make I/O connections. In that
case, make I/O connections first and save mounting until last.
Serial Port
If you intend to use the router under an external control sys-
tem, connect the 9-pin serial port to a serial port of your sys-
tem. The communication protocol is NVSP over RS-422 or RS-
485, at 38,400 Baud, for routers and is not available for
remote panel modules. Contact Grass Valley technical sup-
port for more information and to obtain the NVSP protocol
guide which is essential.
I/O Cables, Video Reference Cable
The 64×64 routers are of modular construction and have DIN
1.0/2.3 I/O connectors. Setup for the 64×64 routers is differ-
ent from the other routers. See
Connections for 64×64 Rout-
ers , following.
The analog audio routers have DB25 connectors. The
machine control routers have RJ-45 connectors. The other
routers have BNC connector. See figures 6, 7, and 8.
 If your routers are in an NV9000 router control system, the con-
figuration you create for your NV9000 system will include your
device connections.
Connect the video reference input. (Doing this is optional,
but recommended.) This connection is loop-through, non-
terminating. Be sure to terminate the output of the last con-
nector in the series with a 75Ω BNC terminator. See Figure 6.
