Installation
Rack Mount
1 Set the position of the 16-position rotary switch on the front of the router. (It is not on the
control panel. If the control panel is mounted on the router, you must detach the control
panel from the router to access the rotary switch.)
If you have a single CR6400 router, set the switch to any non-zero position.
If you have more than one CR6400 router, their rotary switches must be set to positions in
the range 1–4. The switch positions for the routers must all be different.
Use a small slotted screwdriver to turn the rotary switch.
2 If the router is to have a CP6464 control panel, place the panel on the front of the router,
mating the electrical connector on the panel to the electrical connector on the router. The fit
requires only minimal force. Tighten the knurled screws that secure the control panel to the
router. Tabs at the ends of the control panel fit in slots in the face of the router, helping you
align the panel to the router.
You may design, fabricate, and install a control panel’s button legends (clear inserts that fit
under the clear plastic button caps) at any time.
3 Mount, and secure, the router assembly in the rack.
The CR6400 router’s mounting holes on each side are spaced 3” (76mm) vertically and allow
approximately 1/8” (3mm) of play horizontally.
Position the router so that its mounting holes are aligned with the holes in the rack. Use 4
rack-mounting screws to secure the router to the rack.
4 If you are using the router on a network, connect an Ethernet cable (RJ-45) from the network
switch to the Ethernet port of the router.

5 Optionally, connect your video reference.
SDI signals require a reference to perform switches in accordance with SMPTE RP168.
The router 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 refer-
ence connector to the input of another. The output of the last connector in the series should
be terminated with a 75
W BNC terminator.
6 Optionally connect the ground lug to earth 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 equip-
ment in a power anomaly such as a lightning strike.
7 Connect one or both power supplies.
The external power supply’s cable connector has 4 pins.
The enclosing ring of the cable connector is connected to ground. Be very careful not to
short the power pins (+48V) to the ring. It is easy to do.
Always disconnect the power supply from AC power before connecting the power
supply to the router. Then reconnect AC power to the power supply.
See
on page 115 if either of the power LEDs on the front of the router (or
control panel) fails to light.
8 Connect input devices and output devices. The exact connections are, of course, determined
by the requirements of your system.
