There are several terms and acronyms that you should become familiar with before
reading this manual. They are shown below.

Term/Acronym Definition

Crosspoint The electronic switch that assigns one of the inputs

on the matrix crosspoint modules to an output.

Chapter

1

Destination The output of a routing switcher connected to a

device that receives signals from the output of the
switcher.

Input Connected to the source that provides the signal to

the switcher.

Matrix The crosspoint array of the switcher module that

Warnings & Safety Regulations

The information in the following section provides important warnings and safety
guidelines for both the operator and service personnel. Specific warnings and cautions
may be found throughout this manual. Please read and follow the important safety
precautions noting especially those instructions relating to risk of fire, electrical shock and
injury to persons.

Any instructions in this manual that require opening the equipment cover or enclosure are
intended for use by qualified service personnel only. To reduce the risk of electrical
shock, do not perform any servicing other than what is contained in the operating
instructions unless you are qualified.

Warnings

 Heed all warnings on the unit and in the operating instructions.
 Disconnect AC power before installing any options.
 Do not use this product in or near water.
 This product is grounded through the grounding conductor of the power

cord. To avoid electrical shock, plug the power cord into a properly wired
receptacle before connecting inputs and outputs.

Cautions

 Route power cords and other cables so that they are not likely to be

damaged, or create a hazard.

 Dangerous voltages exist at several points in this product. To avoid personal

injury, do not touch unsafe connections and com ponents when the power is
on.

 To avoid fire hazard, use only the specified type, correct voltage, and

current rating of fuse. Always refer fuse replacement to qualified service
personnel.

 Have qualified personnel perform safety checks after any completed service
 This is an FCC class A product. In a domestic environment, this product

may cause radio interference, in which case the user may be required to take
necessary measures.

 Use the proper AC voltage to supply power to the switcher. When installing

equipment, do not attach the power cord to building surfaces.

 To prevent damage to equipment when replacing fuses, locate and correct

trouble that caused the fuse to blow before applying power.

 Use only the recommended interconnect cables to connect the switcher to

other frames.

 Follow static precautions at all times when handling the equipment.

2

Cautions (continued)

 Leave the side, top, and bottom of the frame clear for air convection cooling

and to allow room for cabling. Slot and openings in the frame are provided
for ventilation and should not be blocked.

 Only an authorized Sierra Video Systems technician should service the

switchers. Any user who makes changes or modifications to the unit
without the expressed approval of the Sierra Video Systems will void the
warranty.

Pow er Supply Cords

North American Power Supply Cords

This equipment is supplied with North American power cords with molded grounded plug
(NEMA-15P) at one end and molded grounding connector (IEC 320-C13) at the other
end. Conductors are CEE color coded, light blue (neutral), brown (line), and green/yellow
(ground). Operation of the equipment at voltages exceeding 130VAC will require power
supply cords that comply with NEMA configurations.

External Power Supplies

Shasta 1616D

The 905016 frame is powered by an external power supply. The power supply is a
PW11003, 22VAC, 40VA supply.

EMC Regulatory Notices

Federal Communications Commission (FCC) Part 15 Information: This device complies
with Part 15 of the FCC standard rules. Operation is subject to the following conditions:

This device may not cause harmful interference

This device must accept any interference received including interference that may cause
undesirable operations.

Delivery Damage Inspection

Carefully inspect the frame and exterior components to be sure that there has been no
shipping damage. Make sure all modules are seated correctly and have not detached
during shipment. Also, make sure the input buffer modules on the rear panel are secure.

Shasta Family Overview

Introduction

The Shasta Family is Sierra Video Systems’ most extensive line of digital video routing
switchers with digital (AES/EBU) or analog audio, setting the standard in mid-sized
switchers for more than a decade. Shasta frames can be populated with limited modules,
providing flexibility for future expansion.

The Shasta family of routing switchers can contain video and audio in one frame or video
in one frame and audio in a separate frame with the frames connected together by a J1
connecting cable. Shasta routing switchers can be video or audio only. Multiple frames
can be connected together (up to 8 levels) under the same Shasta control system. For
multiple frames, only one Shasta serial control module is required.

An optional RS-232/422 serial interface control gives the Shasta extensive control
options. The Shasta family can endure the most demanding of applications.

Factors Affecting Quality of Results

There are many factors affecting the quality of results when signals are transmitted from
a source to a destination.

 Signal cables — Use only the best quality cables to avoid interference

and degraded signal quality and elevated noise levels.

 Sockets and connectors of the sources and destinations — Use only the

highest quality, since "zero ohm" connection resistance is the target.
Connectors should also match the required impedance (75 ohm in
video) to minimize return loss.

 Amplifying circuitry — Must have quality performance when the

desired end result is high linearity, low distortion, and low noise.

 Distance between sources and destinations — Plays a major role in the

final result. For long distances (over 15 meters) between sources and
destinations, special measures should be taken to avoid high frequency
cable losses. These measures include using higher quality cables and/or
adding line cable equalizing amplifiers.

 Interference from neighboring electrical appliances — These can have

an adverse affect on signal quality. Balanced audio lines are less prone
to interference, but unbalanced audio should be installed away from
any main power lines, electric motors, transmitters, etc. even when the
cables are shielded.

CAUTION!

Only an authorized Sierra Video Systems technician can service the switchers. Any user
who makes changes or modifications to the unit without the expressed approval of the
manufacturer will void the warranty

Use the proper AC voltage to supply power to the switcher.
Use only the recommended interconnect cables to connect the switcher to other frames.

Installation

Introduction

The Shasta 88D routing switcher consists of two pieces, the electronics frame and a
separate in-line power supply. The electronics portion of the 88D is contained on a single
plug-in circuit board which plugs into a 1RU frame.

Rack Mounting

Carefully inspect the frame to ensure that there has been no shipping damage. Make
sure all shipping material is removed from the router frame.

Chapter

2

The Shasta 88D routing switcher can be rack mounted in a standard 19" (RU) EIA rack
assembly and includes rack "ears" at the ends of the front of the frames. None of the
switcher models require spacing above or below the unit for ventilation.

If ample space exists, a 1RU spacing gap is recommended.

To rack mount the routing switcher, simply place the unit's rack ears against the rack rails
of the rack, and insert proper rack screws through each of the holes in the rack ears.
Always rack mount the routing switcher prior to plugging the unit into a power receptacle
or attaching any cables.

Dimensions

The dimensions of the Shasta 1616D (905016) are;

Height- 1RU (1.75”)
Depth- 8.5”
Width- 19”
