OVERVIEW

X1200 Series Router Manual

1. OVERVIEW

The X1200 series twelve input routing switchers provide a convenient, low cost way to route Standard and
High definition serial digital signals. The X1200S routers are used for 270, 360 & 540Mb/s standard
definition serial digital signals, while the X1200H routers are used for 1.5Gb/s HDTV serial digital signals.

The router is available in video only or video with AES configurations. The X1202S-AES and
X1202H-AES units come with 2 levels of AES audio routing for each of the two video busses. The
X1202S-AES4 and X1202H-AES4 units come with 4 levels of AES audio routing for each of the two video
busses. The X1201 routers have only one video bus and similar audio configurations. The AES output
busses can be used in an audio follow video mode, or can be broken away from their associated video
buss. Table 1-1 shows the model numbers of the basic routers and the capabilities of each.

Table 1-1: Basic Router Models and Features

**Some early versions of the X1202H-AES models were shipped with two audio breakout panels. On
these units, the AES audio router sections can also be configured as four 12 x 1 AES audio busses. (The
assignment of which mode the AES section of the router operates and which AES busses are associated
to the Video busses is programmable from the Setup menu.)

The router electronics is housed in a 1RU rack mount frame with breakout panels for the audio
connections. The standard router has built-in front panel controls, but can also be purchased with a rack
mount remote control panel that replaces the built-in control panel (RCP version). An additional remote
control panel (X1202S-REMOTE or X1202H-REMOTE) can also be ordered for any version. All units can
also be controlled by contact closures on the GPI control port or through the RS-232 serial remote control
port using industry standard switcher protocols.

The SoftSwitch versions (referred to as SS versions throughout this manual) of the router have the
following additional features. The Video 1 output has adjustable vertical timing with respect to the genlock
input, and line synchronizers on the video inputs can accommodate differences in timing up to
approximately +/- one half line for the V1 output. All the AES outputs will have a continuous AES carrier
locked to either the video genlock or DARS reference (when the DARS reference is used, Z bit alignment
of the AES outputs is also guaranteed). The audio outputs that follow the Video 1 buss use Evertz patent

pending SoftSwitch technology to eliminate audible pops when switches are performed. For the
SoftSwitch technology to function correctly, the audio sources must be synchronous with the chosen

Table 1-2: SoftSwitch Router Models

Panels

The Embedded SoftSwitch (referred to as ESS versions throughout this manual) versions of the router
have all the features of the SS versions as well as the following additional features. The embedded audio

on the Video 1 buss uses Evertz patent pending SoftSwitch technology to eliminate audible pops when
switches are performed. For the Embedded SoftSwitch technology to function correctly, the AES

sources must be synchronous with the Video reference and the Audio Reference for the router must be
set to video (see section 3.6.4). If Embedded SoftSwitch functionality is not required (e.g. Dolby E in the

embedded stream) then the DARS reference can be used with the AES portions of the router. Table 1-3
shows the model numbers of the Embedded SoftSwitch equipped routers and the capabilities of each.

1.1. HOW TO USE THIS MANUAL

This manual is organised into 5 chapters: Overview, Installation, Operation, Technical Description, Serial
Protocol, Output Configurations, and System Timing. This chapter contains a quick summary of the router
features and a glossary to define concepts and terms used throughout the remainder of the manual.

Chapter 2 gives a detailed description of the rear panel connectors, and how the router should be
connected into your system.

Chapter 3 gives a detailed description of the operation of the front panel controls, starting with an overview
of the pushbuttons and front panel indicators. The operation of the router using the optional remote
control panel is identical to the front panel.

Chapter 4 gives an overview of how to update the firmware in the unit and other technical issues.

Chapter 5 is a programmer’s reference to the serial control protocol.

Chapter 6 provides a pictorial representation of video and audio output configurations for each version of
the router.

Chapter 7 provides a few video timing examples to aid the system designer in properly timing the router.

Items of special note are indicated with a double box like this.

X1200 Series Router Manual

CCIR-601: (This document now known as ITU-R601). An international standard for component digital

television from which was derived SMPTE 125M and EBU 3246-E standards. CCIR-601
defines the sampling systems, matrix values and filter characteristics for both Y, B-Y, R-Y and
RGB component digital television signals.

CCIR-656: (This document now known as ITU-R656). The physical parallel and serial interconnect

scheme for CCIR-601. CCIR-656 defines the parallel connector pinouts as well as the
blanking, sync and multiplexing schemes used in both parallel and serial interfaces. It reflects
definitions found in EBU Tech 3267 (for 625 line systems) and SMPTE 125M (parallel 525 line
systems) and SMPTE 259M (serial 525 line systems).

CLIFF EFFECT: (also referred to as the ‘digital cliff’) This is a phenomenon found in digital video systems

that describes the sudden deterioration of picture quality due to excessive bit errors, often
caused by excessive cable lengths. The digital signal will be perfect even though one of its
signal parameters is approaching or passing the specified limits. At a given moment however,
the parameter will reach a point where the data can no longer be interpreted correctly, and the
picture will be totally unrecognisable.

COMPONENT ANALOG: The non-encoded output of a camera, video tape recorder, etc., consisting of

the three primary colour signals: red, green, and blue (RGB) that together convey all necessary
picture information. In some component video formats these three components have been
translated into a luminance signal and two colour difference signals, for example Y, B-Y, R-Y.

COMPONENT DIGITAL: A digital representation of a component analog signal set, most often Y, B-Y,

R-Y. The encoding parameters are specified by CCIR-601. The parallel interface is specified
by CCIR-656 and SMPTE 125M.

COMPOSITE ANALOG: An encoded video signal such as NTSC or PAL video that includes

horizontal and vertical synchronising information.

COMPOSITE DIGITAL: A digitally encoded video signal, such as NTSC or PAL video that includes

horizontal and vertical synchronising information.

D1: A component digital video recording format that uses data conforming to the CCIR-601 standard.

Records on 19 mm magnetic tape. (Often used incorrectly to refer to component digital video.)

D2: A composite digital video recording format that uses data conforming to SMPTE 244M. Records

on 19 mm magnetic tape. (Often used incorrectly to refer to composite digital video.)

D3: A composite digital video recording format that uses data conforming to SMPTE 244M. Records

on 1/2" magnetic tape.

EBU (European Broadcasting Union): An organisation of European broadcasters that among other

activities provides technical recommendations for the 625/50 line television systems.

EBU TECH 3267-E: The EBU recommendation for the parallel interface of 625 line digital video signal.

This is a revision of the earlier EBU Tech 3246-E standard that was in turn derived from CCIR-

601.

EDH: Error Detection and Handling (EDH) is defined in SMPTE RP-165 as a method of determining

when bit errors have occurred along the digital video path. According to RP-165, two error
detection checkwords are used, one for active picture samples, and the other on a full field of
samples. Three sets of flags are used to convey information regarding detected errors, to

Page 1-8

Revision 1.3.2

OVERVIEW

X1200 Series Router Manual

facilitate identification of faulty equipment or cabling. One set of flags is associated with each
checkword, and the third is used to evaluate ancillary data integrity. The checkwords and flags
are combined into a special error detection data packet that is included as ancillary data in the
serial digital signal.

EMBEDDED AUDIO: Digital audio is multiplexed onto a serial digital video data stream.

GVG TEN-XL: A 10 x 1 router made by the Grass Valley Group. The serial control protocol used for this

router has become an industry standard. The control protocol used to control the Evertz 95XX
series routers is an extension of this protocol.

ITU: The United Nations regulatory body governing all forms of communications. ITU-R (previously

CCIR) regulates the radio frequency spectrum, while ITU-T (previously CCITT) deals with the
telecommunications standards.

ITU-R601: See CCIR601

PIXEL:The smallest distinguishable and resolvable area in a video image. A single point on the screen.

In digital video, a single sample of the picture. Derived from the words picture element.

RESOLUTION: The number of bits (four, eight, ten, etc.) determines the resolution of the signal.

Eight bits is the minimum resolution for broadcast television signals.

4 bits = a resolution of 1 in 16.
8 bits = a resolution of 1 in 256.
10 bits = a resolution of 1 in 1024.

SERIAL DIGITAL: Digital information that is transmitted in serial form. Often used informally to refer to

serial digital television signals.

SMPTE (Society of Motion Picture and Television Engineers): A professional organisation that

recommends standards for the film and television industries.

SMPTE 125M: The SMPTE standard for bit parallel digital interface for component video signals.

SMPTE 125M defines the parameters required to generate and distribute component video
signals on a parallel interface.

SMPTE 244M: The SMPTE standard for bit parallel digital interface for composite video signals.

SMPTE 244M defines the parameters required to generate and distribute composite video
signals on a parallel interface.

SMPTE 259M: The SMPTE standard for 525 line serial digital component and composite interfaces.

SMPTE 292M: The SMPTE standard for 1125 line serial digital high definition video interfaces.

SMPTE 299M: The SMPTE standard for embedding AES audio into SMPTE 292M serial digital

high definition video.

SoftSwitch: An Evertz patent pending technology the eliminates audio pops and clicks due to

interruptions of the AES carrier. These interruptions are often caused by non-synchronous
switching of the inputs, or may be present from upstream devices. Embedded SoftSwitch

uses the same technologuy to remove pops and clicks from embedded audio.

2.1. REAR PANEL

Figure 2-1: X1202H-AES4 Rear Panel Layout

Figure 2-2: X1202S-AES4 Rear Panel Layout

Sections 2.1.1 to 2.1.6 describe the purpose of the rear panel connectors and the specific signals that
should be connected to the routers. Router versions that have SoftSwitch, Embedded SoftSwitch or
Bypass relay options installed will have the option checked (√) on the rear panel. Chapter 6 provides

pictorial representations of the video and audio output configurations for each version of the router.

2.1.1. Standard Definition Digital Video Connections (X1200S)

SDI VIDEO INPUTS 1 to 12 These BNC connectors are for connecting 10-bit serial digital video signals,

compatible with the SMPTE 259M standard to the respective video input buss.

SDI VIDEO OUTPUTS 1 and 2 There are two video output connectors for each of the two video

router busses on X1202S routers. The Video from the selected Video Input buss will be
available on two outputs for each bus. X1201S routers do not have the Second output bus.

When the bypass relay option is fitted, INPUT 1 is protected by a bypass relay to the adjacent
OUTPUT 1 BNC for both X1202S and X1201S routers. INPUT 12 is protected by a bypass
relay to the adjacent OUTPUT 2 BNC on the X1202S routers only. The bypass relays will
activate in the event of power loss to the router and can also be activated from the front panel
menu.

2.1.2. High Definition Digital Video Connections (X1202H)

2.1.6. Power Connections

The router has one or two (redundant supply is optional) universal power supplies that operate on either
115 Volt / 60 Hz or 230 Volt / 50 Hz AC.

2.2. MOUNTING

The Router is equipped with rack mounting angles and fits into a standard 19 inch by 1.75 inch by 17.75
inch (483 mm x 45 mm x 451mm) rack space. The mounting angles may be removed if rack mounting is
not desired.

2.3. POWER REQUIREMENTS

2.3.1. Selecting the Correct Mains Voltage

Power requirements are 115 or 230 volts AC at 50 or 60 Hz. The router has a universal power supply that
automatically senses the input voltage. Power should be applied by connecting a 3-wire grounding type
power supply cord to the power entry module on the rear panel. The power cord should be minimum 18
AWG wire size; type SVT marked VW-1, maximum 2.5 m in length. If the router is fitted with the
redundant power supply there will be an additional IEC-320 connector on the rear panel.

If the router is fitted with dual power supplies, make sure that power is removed

!

The IEC 320 power entry module combines a standard power inlet connector, two 5 x 20 mm fuse holders
and an EMI line filter.

2.3.2. Changing the Fuses

The fuse holder is located inside the power entry module. To change the fuses, pull out the fuse holder
from the power entry module using a small screwdriver. The fuse holder contains two fuses, one for the
line and one for the neutral side of the mains connection. Pull out the blown fuse and place a fuse of the
correct value in its place. Use slo blo (time delay) 5 x 20 mm fuses rated for 250 Volts with a current
rating of 1 amp. Carefully reinsert the fuse holder into the power entry module.

from both supplies before performing any work on the unit.

Never replace with a fuse of greater value.

2.4. CONNECTING THE REMOTE CONTROL PANEL

The X1200 series routers can be sold with integrated front panel control, or with a rack mountable remote
control panel (RCP version). On the RCP version, the front panel of the main unit has only the PSU
Status indicators. A second control panel (model X1202-REMOTE) can be added to either version.

2.4.1. Connecting The Primary Remote Control Panel (RCP Version)

On the RCP version of the router, the primary control panel is connected to the REMOTE PANEL
connector using a straight through cable provided. For longer distances, simply make your own cable of
the required length according to the diagram in Table 2-4. Communications to the remote panel is through
a standard straight through RS-422 connection, so the panel can be located up to 1000 feet from the main
electronics unit. A plug in 12 VDC adapter supplies power for the remote control panel.
