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.

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)
HD VIDEO INPUTS 1 to 12 These BNC connectors are for connecting 10-bit serial digital video signals,
compatible with the SMPTE 292M standard to the respective video input buss.
HD VIDEO OUTPUTS 1 and 2 There are two video output connectors for each of the two video
router busses. The Video from the selected Video Input buss will be available on two outputs

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.
INSTALLATION
Revision 1.3.2
Page 2-5
X1200 Series Router Manual
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.

On either the Front Panel Control or Remote Control version of the router a second control panel can be
connected to the REMOTE CONTROL 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. The
default configuration of the REMOTE CONTROL port on the router is RS-232. Before connecting the
remote panel the port must be configured as a SMPTE 207M Tributary as shown in Table 2-2. To
reconfigure the port the user must remove the top cover and reposition jumper J26 so that it is on pins 2 &
3 (toward header J23) and move the ribbon. 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.
2.5. CONNECTING THE GENERAL PURPOSE INPUTS AND OUTPUTS
The 25 pin GPI/O connector has 14 programmable general purpose inputs (GPI) and 4 programmable
general purpose outputs (GPO) as shown in Table 2-3. The schematic representation is in Figure 2-4.
The GPIs are opto-isolated inputs that can be powered from an external source or from the frame. The
GPOs are relay contacts that are normally closed when the power to the router is off.

2.5.1. Connecting the General Purpose Inputs
The GPI’s are used to activate video and audio bus crosspoints and are programmable in a number of
configurations. The GPIs can be configured to operate in one of 3 encoded modes. In these modes,
many of the GPI inputs are pre-assigned to a function. The unused inputs are still available for the user to
assign to a particular function using the Program Gpi’s menu item. When the GPI Encoding is set to none,
all 14 inputs are available for the user to assign to particular functions. Sections 3.12.3.1 to 3.12.3.3
describe how each of the GPI encoding modes works and which inputs are available for user assignment.
When the GPI inputs are independently programmed, they can be set to activate on rising or falling edges,
or high or low levels. The factory default is for low level activation, which means a ground level on the
input will trigger the GPI function when the Opto isolator is normally powered. See Figure 2.2 and 2.3
The high level activation can be used when you need to trigger the GPI function by providing a positive
voltage to a GPI input. This mode is not generally used and should not be considered a first choice.
The falling edge activation is used to trigger a GPI function by removing a provided voltage to a GPI or by
making a closure to ground when the Opto isolator is already powered. The falling edge GPI will respond
the same as a low level activation when the opto isolator is normally powered.
The rising edge activation is used to trigger a GPI function when power is provided to the Opto isolator, or
when the GPI closure to ground is released. This function can be used to trigger a GPI function when a
GPO error tally is released.
The user can connect GP+5V supplied from the frame (Vint pin) into the Vext pin to provide power to the
GPIO opto-isolator circuitry. In this configuration the user can activate GPIs simply by connecting the GPI
input pins to Ground (see Figure 2-5). This can be done with a button, switch, relay or an open collector
transistor.
Warning: Do not connect GP+5V from one frame to another frames GP+5V.

2.5.2. Connecting the General Purpose Outputs
The Programmable GPOs are used to trigger alarms or to provide a limited tally capability. The GPOs will
be in the de-energised state when the power is off so all contacts will be closed. When the router is
powered up the GPO Relay contacts will open. An alarm or tally will cause a contact closure. The 4 GPO
contact sets can be operated in one of two encoded modes. The GPOs can be configured to operate in
one of 2 encoded modes. In these modes, many of the GPO contacts are pre-assigned to a function.
When the GPO Encoding is set to none, all 4 contact sets are available for the user to assign to particular
functions. Section 3.13.3 describes how each of the GPO encoding modes works and how to configure
the GPOs using the GPO SETUP menu.

2.5.3. GPI/O Examples
By careful use of the GPI’s and GPOs one can create some unique control scenarios for controlling the
Router, Figure 2-7 shows one such application. By setting up jumpers for the GPI/O connector and setting
the GPI/O configurations in the router Setup menu, one can create an auto changeover for a program
feed. In this configuration when input 1 fails and that input is currently selected on the output of bus V1,
The router will automatically select input 2.

If the “CH 1 Return “ switch is closed input 1 will be automatically selected when it is present again. This
has a down side that if the Input 1 signal failure is sporadic the router will chatter between input 1 and 2.
The purpose here is to show the use of a rising edge GPI trigger.
Also interesting to note that this functionality can co-exist with the HEX and AFV HEX GPI encoding as
GPI 11 and 12 are both available for user functions in these encoded GPI modes.
2.6. CONTROLLING THE ROUTER USING THE EXTERNAL SERIAL PROTOCOL
The X1200 series routers can be controlled from router control devices or it can control other devices
employing industry standard router control protocols. Currently the only control protocol supported is the
Grass Valley Ten-XL ASCII protocol. The control device is connected to the router using the
REMOTE CTL connector on the rear panel. The REMOTE CTL menu is used to configure the
REMOTE CTL port for external control using the Baud Rate, Serial Format, Serial Address and Serial
Control menu items. See section 3.14 for information about configuring the REMOTE CTL port
parameters. See chapter 5 for detailed information about controlling the router
2.6.1. Connecting the Router to a Grass Valley Ten XL ASCII Control Device
Use the External control item on the Setup Menu and select Gvg ten xl ASCII protocol. The Baud
Rate, Serial Address, and Serial Format menu settings must be set to match those required by the GVG
control device. If the Router is being controlled by another device set the Serial Control menu setting to
slave. If the router is controlling another device using its remote control port then set the Serial Control
menu setting to master. The REMOTE CTL port is shipped from the factory configured for RS232
operation. If you require RS-422 operation then you will have to change the port wiring as described in
section 2.4.2.

3. OPERATION
The router electronics is housed in a 1RU rack mount frame and is controlled from the built-in front panel
controls. Each model can also be purchased with an optional rack mount remote control panel that
replaces the built-in control panel. Operation of the Remote control panel is identical to the built in control
panel. A second control panel can also be purchased for the routers. This panel is connected to the
REMOTE CTL port and allows the user to access the all of the router functions except the Setup menu.
All units can also be controlled by contact closures on the GPI control port or through the REMOTE CTL
serial remote control port using Grass Valley switcher protocol.

system problems.
Video Ref. Fail This message will alternate with the current display message when the video
reference signal is not present.
DARS Ref. Fail This message will alternate with the current display message when the Audio
Reference menu item is set to DARS, and the DARS reference signal is not present. The
Audio reference will default to the Video Reference in this case.
Genlock Fail This message will alternate with the current display message when the Audio
Reference menu item is set to DARS, and neither the Video Reference or the DARS reference
signal are present.
3.2. OVERVIEW OF FRONT PANEL OPERATION
3.2.1. Audio Follow Video Switching (AFV)
The X1200 series routers have one or two video busses and up to four audio busses (1A, 1B, 2A and 2B)
depending on the model (see Table 1-1).
The X1201 routers fitted with the AES option have a dual 12 x 1 AES configuration and are shipped with
one breakout panel (X1201ABO). On these units audio busses 1A and 1B will follow the video V1 buss.
(See Figure 6-2) The X1201 routers fitted with the AES4 option have a quad 12 x 1 AES configuration
and are shipped with two breakout panels (X1201ABO). On these units audio busses 1A, 1B, 2A and 2B
will follow the video V1 buss. (See Figure 6-3)
The X1202 routers fitted with the AES option have a dual 12 x 2 AES configuration and are shipped with
one breakout panel (X1202ABO). On these units audio busses 1A and 1B will follow the video V1 buss
and audio busses 2A and 2B will follow the video V2 buss. (See Figure 6-6 and Figure 6-7)
The X1202 routers fitted with the AES4 option have a quad 12 x 2 AES configuration and are shipped with
two breakout panels (X1202ABO). On these units output 1 from audio busses 1A, 1B, 2A and 2B will
follow the video V1 buss and output 2 from audio busses 1A, 1B, 2A and 2B will follow the video V2 buss.
(See Figure 6-8 and Figure 6-9)
Page 3-2
Revision 1.3.2
OPERATION
X1200 Series Router Manual
Some early X1202 routers fitted with the AES option were shipped with two breakout panels. These units
can be used in either a dual 12 x 2 configuration or quad 12 x 1 configuration where the audio busses can
be associated with either video buss V1 or V2. When these units were shipped from the factory they were
configured in the quad 12 x 1 mode and audio busses 1A and 1B are assigned to video buss V1. Similarly
audio busses 2A and 2B are assigned to video buss V2. (See Figure 6-10 to Figure 6-13)
To select a crosspoint for buss V1, press the V1 button and then select the desired input by pressing one
of the buttons 1 to 12. Note that when buss V1 is selected the V1 button will light as well as the buttons
corresponding to the audio busses that are assigned to follow video buss V1. When the desired input is
selected the button for that bus will light and the video label for that input will be displayed on the front
panel display. The input labels for the associated audio busses may be displayed momentary by pressing
the respective audio buss keys.
When selecting an audio bus that has been assigned to a video bus, all the buttons for that AFV assigned
group will light and any input selection will effect the whole group.
On early versions of the X1202 routers with the AES option operating in the quad 12 x 1 configuration, the
Audio busses that follow the respective video busses can be changed using the Input Setup menu. Any
audio channel that has not been assigned to an AFV group will not be effected by V1 or V2 switch
selections and may be independently controlled by pressing the respective audio buss selector button.
The switch selection may be disallowed if there is no video present on the input chosen depending on the
setting of the No Video Action menu item in the Input Setup menu. A message No Video Present will
be temporally displayed. Similarly if the Video input has been turned off using the Video V1 and V2 menu
item in the Input Setup menu, the switch will be disallowed and the message Input turned off will be
displayed. Turning off Audio inputs in the Input Setup menu will cause the audio switch to be ignored by
any AFV switching.
3.2.2. Breakaway Audio On An Audio Follow Video Group
The occasion may arise were one wants to select a different audio input than what the video buss
normally dictates. This is a breakaway function and the router allows for this mode. To initiate a
breakaway function the first step is select the desired input for the Video buss as described in section
3.2.1. Then press the BREAKAWAY key to enter the breakaway selection mode. The BREAKAWAY
key will blink to indicate that breakaway mode has been entered. At the same time all of the audio buss
keys for that breakaway group will light along with the current selected input key. To break away audio
Bus 1B press that key. The Audio 1B key will blink to indicate the specific breakaway buss. Press the
key for the desired input selection for the audio 1B buss. The selected input key will also blink indicating
that it will be selected for audio buss 1B when the breakaway is completed. The other input key that is still
lit represents the buss selection for the V1 buss and the 1A audio buss that have not changed. The
breakaway is now set up. To complete the breakaway, press the BREAKAWAY key again. The panel
will now show the BREAKAWAY key lit and two input keys will also be lit.
To understand which inputs belong to which buss, press the button for the buss in question. Only the
input button and the button for that buss will light - all other keys will be temporally extinguished. During
that short interval the display will show the input label for that input key.
To cancel the breakaway simply press the next input selection. At this time all the busses in that AFV
group will track to that input selection.
It is also possible when in breakaway mode to select breakaways for all the Audio busses that are
assigned to follow the video. It is also possible for the breakaway to work on the video bus. This allows
for a salvo switch where all audio and video busses are switched to different inputs.
OPERATION
Revision 1.3.2
Page 3-3
X1200 Series Router Manual
Turning off Audio inputs in the Input Setup menu will cause the audio switch to be ignored by any AFV
Breakaway switching.
3.2.3. Independent Audio Bus Switching
On the early versions of the X1202 router that can be configured as a quad 12 x 1 AES, the audio busses
can be switched independent of the video buss. If one wishes to have an audio bus independent of an
AFV group switch, then that bus needs to be released from its AFV assignment using the Input Setup
menu. This shall be described later in the manual. If audio 1B has been released from its AFV
assignment it will switch as an independent bus.
When one selects the 1B key it will light up and all other bus selection keys will extinguish. One of the
twelve input keys will light and the display will show the audio input label for the selection. Pressing
another input key will cause that input to be selected on that bus only.
In independent Audio Bus switching, switch selection will be disallowed if the input has been turned off in
the Input Setup menu. A message “Input turned off” will be temporally displayed.

The standard definition X1200S series router can accept only NTSC or PAL
video references.
The high definition X1200H series router can accept NTSC or PAL, or Trilevel sync HD video references.
In general, the reference video should be chosen to match the standard of
the video program material passing through the router. For HD program
video, a standard definition reference video can be used as long as it is at
the same frame rate.

This menu item is used to set the vertical phase of the V1 output on the
SoftSwitch and Embedded SoftSwitch versions of the routers. The
course phase has valid values from 1 to the number of lines per frame and
adjusts V1 output phase delayed with respect to reference video. The
timing of the V2 output is not adjustable.
When the course phase is adjusted the “course phase” label will blink, when
the incoming signal that was selected when entering the set up menu, is
within the line synchronizer range.

!
This menu item is used to set the line synchronizer acceptance range with
respect to the video reference for the V1 output on the SoftSwitch and
Embedded SoftSwitch routers.
Setting course phase to “1” and line phase to “0” are the standard settings. This
will allow any incoming video signal with a +/- one half line timing with respect to
the applied video reference, to switch cleanly on the V1 bus. The output on V1
will remain constant at 1 line delayed with respect to the applied video reference
signal. The timing of the V2 output is not adjustable.
The line phase has following valid values:
1202S 0 to +/-700 samples (approx. +/- 25 µsec)
1202H 0 to +/-940 samples (approx. +/- 12 µsec) for 1080 line standards
1202H 0 to +/-620 samples (approx. +/- 8 µsec) for 720 line standards
Line Phase is specific to a particular video standard. Therefore, if the Input
Standard is changed from a 1080 line standard to a 720 line standard, the Line
Phase will be reset to 0, and must be set up again for the new video standard.
The Course Phase and Line Phase adjustments are REAL TIME ADJUSTMENTS
and will effect router timing even without the menu EXIT AND SAVE menu
selection. The EXIT AND SAVE menu item will save the values while the EXIT
AND NO SAVE menu item will return the router to the original values. For difficult
timing situations the presets can be used for different timing setups.

This menu is used to select the type of audio reference being used for the
SoftSwitch and Embedded SoftSwitch routers. These routers can accept a
DARS reference signal to insure the Z bit alignment on the AES outputs. If
video is selected, the Z bit alignment of the AES outputs is random. If DARS is
selected and the DARS reference is absent, the router will revert to video lock.
On the SS routers, for the SoftSwitch technology to function correctly, the
audio sources must be synchronous with the chosen Audio Reference.
On the ESS routers, 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 should be set to video. (If you are using a
DARS reference with ESS, then the DARS reference must be locked to the
video reference.) If Embedded SoftSwitch functionality is not required (e.g.
Dolby E in the embedded stream) then the AE SoftSwitch can be disabled and
the router can function the same as a SoftSwitch equipped router.

In the 2(12 x 2) configuration audio busses 1A and 1B are associated with
video buss 1 and 2A and 2B are associated with video buss 2. The Audio
follow V1 and Audio follow V2 menu items are disabled.
In the 4(12 x 1) configuration the four audio busses can be associated with
either video buss V1 or V2 using the Audio follow V1 and Audio follow V2
menu items.
3.8.2. Setting up the Audio Follow Video Groups
On early units fitted with the AES option that were shipped with two breakout panels, when the AES Mode
is set to 4(12x1), the Audio Follow V1 and Audio Follow V2 menu items set up which audio busses are
assigned to follow video buss 1 and 2 respectively. For simplicity only the menu items for the V1 are
shown in the manual. These menu items are disabled when these routers are in the 2(12x2) mode, and
for later routers shipped with one breakout panel.

On early units fitted with the AES option that were shipped with two breakout panels, when the AES Mode
is set to 4(12x1), the Audio 2A Inputs and Audio 2B Inputs menu items allow the user to disable unused
inputs on the Audio 2A and 2B busses. On these routers, when the AES Mode is set to 2(12x2), the inputs
for the 2A and 2B busses are taken from the 1A and 1B inputs, so these menu items are disabled.
3.8.4. Configuring What To Do When There Is No Video Input Present
INPUT SETUP
No video action
This menu item determines whether a selected switch will occur if there is
no video present on the selected input.
no video:take

3.9. LABELING THE VIDEO AND AUDIO INPUTS
The X1200 Series Routers provide a simple method of identifying each of the video sources with a 16
character label. The INPUT LABEL menu is used to change the default input labels for the video and
audio inputs. You can either input the label text from a text file (see section 3.9.1), or manually update the
individual input labels from the front panel (see section 3.9.2). The chart below shows the items available
in the INPUT LABEL menu.
On early units fitted with the AES option that were shipped with two breakout panels, when the AES Mode
is set to 4(12x1), the Label Audio 2a and Label Audio 2b menu items allow the user to label the inputs on
the Audio 2A and 2B busses. On these routers, when the AES Mode is set to 2(12x2), the inputs for the
2A and 2B busses are taken from the 1A and 1B inputs, so these menu items are disabled.

Revision 1.3.2
OPERATION
X1200 Series Router Manual
It is important to make sure that the structure of the text file that contains the router labels is correct, or the
router will not accept any of the label definitions. The simplest way to create a file with the correct layout
is to download the current labels from the router using the Send File menu choice. You can then just edit
the label names, and then upload the new file back to the router using the Receive File menu choice.
Any serial protocol (remote panel or GVG) that is currently open on the remote port will be closed during
the Label updating procedure. The serial protocol will be reopened once the upload or download has
finished.
Use the procedure described in section 4.3 to upload label text files to the router.
3.9.2. Changing the Input Labels from the Front Panel.
From the Input Label menu use the ↑ & ↓ buttons and press the SELECT key to select the input buss you
wish to label. The method of labelling each of the inputs is the same. The button corresponding to the
buss you have chosen will blink. For simplicity the manual will describe how to label the video inputs.
Press the button corresponding to the input you wish to label. The label associated with the selected input
bus will be displayed on the front panel with the leftmost character blinking. Use the ↑ & ↓ buttons to
change the first character of the displayed label. When you change the blinking character, the buss LED
will stop blinking. When you have selected the desired character, press the SELECT button to save the
changes for the first character and advance to the next character. The buss LED will start blinking again
indicating you have confirmed the changes to the first character. Follow the same procedure until you
have finished entering the label. Make sure that you press the SELECT button after you change the
rightmost character. Press the SETUP button to return to the select input menu. To change the label on
another input press the desired input button and follow the same procedure. When you have changed all
the labels for the selected buss, press the SETUP button to return to the INPUT LABEL menu.

4.2. UPGRADING FIRMWARE
The X1200 series routers contain firmware that is contained in a FLASH EPROM device. From time to
time firmware updates will be provided to add additional features to the unit.
You will need the following equipment in order to update the X1200 Router Firmware
• PC with available communications port. The communication speed is 57600 baud, therefore a 486 PC
or better with a 16550 UART based communications port is recommended.
• “Straight-thru” serial extension cable (DB9 female to DB9 male) or (DB25 female to DB9 male).
• Terminal program that is capable of Xmodem file transfer protocol. (such as HyperTerminal)
• New firmware supplied by Evertz.
4.2.1. Step 1 – Terminal Program Setup.
1. Connect the serial cable to the SERIAL REMOTE DB9 connector on the rear panel
2. Connect the 9 pin connector on the end of the serial update cable to the PCs’ RS-232 communications
port
3. Start the terminal program.

• Proceed to Step 4 for instructions on uploading the firmware.
4.2.1.2. Step 3 – Invoke Upload Mode From The Terminal Program
In the event that you can not initiate upload mode from the front panel menu, you may send commands to
the Router to initiate upload mode using the terminal program.
7. Power up the X1200 Router. After the unit powers up, a banner with the boot code version information
should appear in the terminal window. The cursor to the right of the word BOOT> should be spinning for
about 5 seconds then the unit will continue to boot.
For example:

11. Type the word “upgrade”, without quotes, and hit the <ENTER> key once.
12. The boot code will ask for confirmation. Type "y", without quotes.
13. You should now see a prompt asking you to upload the file.
4.2.2. Step 4 – Uploading the new firmware
14. Upload the “*.bin” file supplied using the X-Modem transfer protocol of your terminal program. If you
do not start the upload within 10 minutes the unit’s Boot code will time out. You can restart the
upgrade process by power cycling the unit.
15. The boot code will indicate whether the operation was successful upon completion of the upload.
For Example:
UPLOAD OKAY
MCF5407 COLD BOOT> |
16. The following is a list of possible reasons for a failed upload:
• If you get the message "transfer cancelled by remote" you must restart the terminal program and
load the bin file, then remove and install the module again.
• The supplied “*.bin” file is corrupt.
• Wrong file specified to be uploaded.
• Wrong file transfer protocol used – make sure you specify Xmodem, not Xmodem 1K.
• The PCs’ RS-232 communications port can’t handle a port speed of 57600.
• Noise induced into the Serial Upgrade cable.
4.2.3. Step 5 – Completing the Upgrade
17. Type the word “boot”, without quotes, and hit the <ENTER> key once or power cycle the unit. The unit
should now reboot.
18. You can now close the terminal program and disconnect the RS-232 serial cable from the PC.
4.3. UPLOADING ROUTER INPUT LABELS FROM A TEXT FILE
The Input Label File menu item allows labels for the video and audio inputs to be input from the serial port
of the router using a simple terminal program such as HyperTerminal. It is important to make sure that the
structure of the text file that contains the router labels is correct, or the router will not accept any of the
label definitions. The simplest way to create a file with the correct layout is to download the current labels
from the router using the Send File menu choice. You can then just edit the label names, and then upload
the new file back to the router using the Receive File menu choice.
Any serial protocol (remote panel or GVG) that is currently open on the remote port will be closed during
the Label updating procedure. The serial protocol will be reopened once the upload or download has
finished.
The following procedure describes the process used to upload labels to the router:

4.3.3. Step 3 – Editing the Label Text File
8. Using a text editor such as Notepad, edit the input labels in the file you have captured.
Note: It is not recommended that you use a word processor such as Microsoft
Word, as it may append hidden control codes into the text file, that will not allows
!
the edited file to be uploaded correctly to the router.
TECHNICAL DESCRIPTION
Revision 1.3.2
Page 4-7
X1200 Series Router Manual
The file structure is as follows:
[category_a]<CR><LF>
labelvar_a1=value 1<CR><LF>
labelvar_a3=value 2<CR><LF>
labelvar_a2=value 3<CR><LF>
[category_b]<CR><LF>
labelvar_b1=value<CR><LF>
labelvar_b2=value<CR><LF>
<CR><LF>
<CR><LF>
<CR><LF>
Note: <CR><LF> = Enter key
Each category is enclosed in square brackets [] and identifies the input category (e.g.[VIDEO],
[AUDIO1A]) for a group of associated label variables. The label variables must follow their associated
category in the file and represent the label names that can be changed in the router. The value that
follows the equals sign is a 16 character maximum length text string that is assigned to the variable.
Alphanumeric characters such as a-z, A-Z, 0-9 and punctuation (ISO Character values 32 to 126) are
valid. Label variables can be in any order as long as they occur in the correct category section of the
file. Physical inputs on the router that do not have an associated label variable will retain their original
value when the label file is uploaded to the router. If a label variable is specified more than once, the
last value in the file will be used.
4.3.4. Step 4 – Upload the New Label file to the Router

5. SERIAL CONTROL OF THE ROUTERS
5.1. GVG TEN-XL ASCII PROTOCOL
The following sections are provided as a technical reference for programmers who want to write their own
software to control the Evertz X1200 series routers using the GVG TEN-XL ASCII command protocol.
There are some hardware differences between the X1200 series routers and the Grass Valley TEN-XL
routers which have required differences in implementation of the protocol for the X1200 series routers.
The GVG Ten XL protocol allows multiple devices to be addressed on a multi-drop serial connection. The
GVG TEN-XL protocol was originally designed to control 10 x 1 routers, therefore each video buss (with its
associated audio busses) in the X1200 routers has its own address. In the X1202 routers, these
addresses are the one set in the Serial Address menu item and the next high number. (i.e. if the Serial
Address menu item is set to 10, then address 10 will correspond to video buss 1 and its associated audio
busses, and address 11 will correspond video buss 2 and its associated audio busses. In the X1201
routers only the serial address set in the Serial Address menu is used.
Some implementations of the GVG Ten XL protocol only allow one device to be addressed on a singledrop serial connection. These implementations use address 0 only. When controlling X1201 routers from
single drop GVG protocol, set the Serial Address to 0. In the X1202 routers, special provisions have been
made to override the programmed Serial Address and re-direct the control to either video buss. Setting
one or two of the GPI Inputs to one of the 10XL Redirect GPI Input functions can accomplish this. When
one GPI is pulled to ground, all serial commands to address 0 will control the respective video buss,
regardless of the setting of the Serial Address menu item. To control the other video buss, ground the
other GPI input. If both GPIs are active at the same time the higher GPI number will have priority. If you
set the Serial Address to 0, and one GPI is programmed to the 10XL redirect V2 function, serial
commands will control V1 buss when the GPI is inactive, and the V2 buss when the GPI is active.
When the X1200 series router is operating in the master mode, it will send out commands to the router
that matches its serial addresses. When the X1200 series router is operating in the slave mode, it will only
respond to commands that match its serial addresses. If two X1200 series routers are connected in a
master/slave configuration, then the addresses of both routers must be set the same.
The Setup Menu in the router must be used to configure the REMOTE CTL port. See section 3.14 for
information about configuring the serial port.
5.1.1. Serial Data Format
In GVG’s TEN-XL ASCII protocol all words sent and received use the following format:
Standard: RS-232 (Can be set to RS-422 by changing internal Jumpers (See section 2.4.2)
Data Rate: Default 38400 Baud (Can be set using the Baud Rate menu item)
Data Format: Default 8 data bits, even parity, 1 stop bit (Can be set using the Serial Format menu item)

5.1.2. Definitions
1 GVG’s TEN-XL ASCII protocol uses standard ASCII hex codes for the transmission of commands.
Programmers must use the hex equivalent code in order to successfully convey commands from
their controlling software to the X1200 series router. Hexadecimal [hex] numbers are represented
with the prefix “0x.”
i.e. decimal “14” = “0x0E.”
2. There are two reserved words in GVG TEN-XL ASCII Protocol. They are illustrated in the table
below.
Reserved
Word
Hexadecimal
Equivalent
Control Character
STX 0x02 ^B
ENQ 0x05 ^E
3. Internal crosspoint numbers are ‘zero-based’, meaning that crosspoint number 1 is accessed as
source 0. Since GVG TEN-XL protocol is based on 10 internal crosspoints and the Evertz 12 x 1
router family contains 12 internal crosspoints it was necessary to extend the protocol to include
crosspoint #11 and #12. Valid sources range from 0 to 11 decimal or 0x00 to 0x0B as shown in
Table 5-1.

5.1.3. Command Formats
Commands are issued by concatenating a sequence of hex codes or parameters as shown in Table 5-2.
All codes are adjacent to each other with no spaces in between bytes.
Parameter Definition
[STX] ASCII hex code for Start of Transmission
[ENQ] ASCII hex code for Inquiry
[HI ADDR] ASCII hex code for the High byte of the address
[LO ADDR] ASCII hex code for the Low byte of the address
[XPT(V)] ASCII hex code for Video crosspoint (i.e.0..9, A, B)
[XPT(A)] ASCII hex code for Audio crosspoint (i.e.0..9, A, B)
[PSUPP] ASCII hex code for the Power Supply Status
(i.e.0x31 = active, 0x30 = either inactive)
Table 5-2: ASCII Command Definitions
5.1.3.1. Write or Take Command
This command is used to switch the active crosspoint in the router.
[STX][HI ADDR][LO ADDR][XPT(V)][XPT(A)]
5.1.3.2. Read or Query Command
This command is used to read back the status of the router.
[STX][HI ADDR][LO ADDR][ENQ]
5.1.3.3. Reply Command String
This reply is sent back from the router in response to the Write or Read command. It indicates which
audio and video crosspoints are active, and the current status of the power supplies.
[XPT(V)][XPT(A)][PSUPP]
5.1.4. Command Examples:
The following are examples of the GVG’s TEN-XL ASCII protocol write and read commands controlling a
X1202S-AES model router. The Serial Address menu item is assumed to be set to 01 so video Buss 1 will
be addressed as 01 and video buss 2 will be addressed as 02.

7. VIDEO TIMING CONSIDERATIONS
The following diagrams show how to set up the system timing under a number of different input signal
conditions so that SoftSwitch and Embedded SoftSwitch equipped routers can perform a clean switch
on the V1 buss.
7.1. ALL INPUT SIGNALS ARE TIMED TO REFERENCE.
This example shows the timing setup for a clean switch when all input signals are in time with the
reference. The V1 buss output will be delayed 1 line with respect to the reference. A clean switch is also
attainable on the V2 buss output.
