works.
See Network Connection , on page 179, for information about router control systems.
5 If you intend to use the router in an automation system or under an third-party control sys-
tem, connect the 9-pin serial port to a serial port of your system. Contact Grass Valley for
information about the serial protocol.
6 Optionally, connect your video reference.
AES routers require a video reference to operate in synchronous mode. SDI routers require a
reference to perform switches in accordance with SMPTE RP168.
Each router (except the machine control routers) has two video reference BNC connectors.
You can connect the reference source to either one. If you have more than one router, you
can “daisy chain” the output of one reference connector to the input of another. The output
of the last connector in the series should be terminated with a 75W BNC terminator.
7 Optionally connect the ground lug to ground. Use copper wire from 14 to 6 AWG. Grounding
decisions are left to you or your facilities manager. Failure to connect the ground will not
affect normal operation, but connecting the ground will protect you and your equipment in
a power anomaly such as a lightning strike.
8 Connect one or both power supplies. First connect the 4-pin connector to PS1 or PS2 on the
rear of the router. The connectors are keyed and snap into place. There is only one way they
fit. Do not force them. Then connect the power supply to AC power.
The second power connection is for redundancy only (protection against failure) and is not a
requirement for operation.
See Trouble-Shooting on page 115 if the power LED on the front of the router (or control
panel) fails to light.
9 Connect input devices and output devices. No particular order or combination is required.
However, if the router is controlled by an Grass Valley router control system, the configura-
tion you create for your system controller will have to match the devices you connect.
Many I/O connections use standard 75W BNC connectors. Use Belden 1694A or equivalent
cable, up to 100m for 3Gig video (80 m for 3Gig CQX routers), up to 150m for HD video or up
to 400m for SD video.
Analog audio connectors are DB25. You can obtain DB25 breakout cables from Grass Valley
or build your own. (The Grass Valley part number is WC0053.)
