1.7.7 AVID DNXHD ® AND APPLE PRORES 422
INTRODUCTION
EVS XS servers feature a native implementation of the Avid DNxHD® and Apple ProRes 422 high definition video codecs. This enables native audio and video file transfers in either direction between the EVS XS servers, and Avid and Apple post-production tools in High Definition. This document explains the impact of using Avid DNxHD® and Apple ProRes codecs on XS servers, on the XNet[2] SDTI network and on the XF[2] in terms of storage capacity, number of usable video channels and network transfers.
For details on how to setup a direct connection between an HD XS server and an Avid or Apple server, please refer to the specific documents (EVS_Avid_integration or EVS_Apple_integration).
VIDEO BITRATE COMPATIBILITY WITH AVID AND APPLE PRODUCTS
Avid DNxHD® is standardized at specific bitrates according to 2 profiles:
1. Standard pro file: 120Mbps in “PAL” (50Hz) and 145M bps in “NTSC” (59.94Hz)
2. High Level profile: 185Mbps in “PAL” (50Hz) and 220Mbps in “NTSC” (59.94Hz) Although Avid DNxHD® is standardized at the specific bitrates mentioned here
above, Avid products can seamlessly read DNxHD® files and streams at other bitrates. DNxHD® pictures at other bitrates than those defined by the 2 official Avid profiles can also be re ferred to as “VC-3” as defined in SMPTE 1019.
To allow users to determine the best balance between picture quality, storage capacity, number of video channels per server, and network speed, EVS XS servers can generate Avid DNxHD® files and streams at any given bitrate between

20Mbps and 220Mbps. These files and streams should remain compatible with Avid production tools.
Apple ProRes 422 is also standardized at specific bitrates according to 3 profiles:
1. Apple ProRes 422 (also sometimes referred to as Apple ProRes 422 SQ):
120Mbps in “PAL” (50Hz) and 1 45Mbps in “NTSC” (59.94Hz)
2. Apple ProRes 422 HQ: 185Mbps in “PAL” (50Hz) and 225Mbps in “NTSC”
(59.94Hz)
3. Apple ProRes 422 LT: 85Mbps in “PAL” (50Hz) and 102Mbps in “NTSC”
(59.94Hz)
Apple ProRes 422 on EVS XS servers is only available at these bitrates.
CHOICES OF BITRATES WHEN USING AVID DNxHD® OR APPLE PRORES 422 WITH EVS XS SERVERS
How to Read the Following Tables ?
1. Video Bitrate: value set by the user in the advanced parameters window of
the XS server
2. Fields/Block: number of video fields that can be stored in one disk block of
8MB, taking into account 8 audio tracks.
3. Actual Bandwidth: this is the actual disk/network bandwidth that is required
for the real time record or real time playback of one video stream and its associated audio tracks.
4. Max. RT Channels: this is the maximum number of video channels (real time
record or real time playback) that one XS server can support for a given frame rate and bitrate. Since an XS server can have a maximum of 4 local video channels, any value higher than 4 means that these additional real time access can be used over the X Net[2] SDTI network.
For mixed configuration with standard and super motion channels on the same server, the following rule must be used to ensure that the settings do not exceed the maximum bandwidth of the server: (nbr of standard channels x their actual bandwidth) + (nbr of super motion channels x their actual bandwidth) must be lower than or equal to 150 MB/s (SCSI disks) or 205 MB/s (SAS disks).
5. Network transfers: the maximum bandwidth over the XNet[2] SDTI network is
approximately 110 MB/s. To determine the number of real time transfers that can occur simultaneously over the network, this number must be divided by the actual bandwidth given in the table for a selected bitrate.
Example: How many re al time transfers can I do over an XN et[2] SDTI network (set at 1485Mbps) if I work with Apple ProR es 422 at 145Mbps in “NTSC”?
Calculation:
Maximum SDTI bandwidth / Actual Bandwidth = re al time transfers: 110MB/s / 18.4MB/s = 6 real time t ransfers. Note: This number is the maximum that the network connection can support. Of course it is also necessary that the XS where the material is stored has enough local disk bandwidth to feed the network accesses, on top of its own local channels (cfr point 4. Max. RT Channels).

IMPORTANT RECOMMENDATION
• The 4ch configurations with 3D and 1080p are only possible with Avid DNxHD®
100 Mbps or
Apple ProRes 422 LT.
1.7.8 RAID LEVEL: 3
The Video Raid uses striping process across 5 SCSI disk drives or across 5 or 6 SAS disk drives. With SCSI disks, the video and audio data is striped over the first 4 drives while the parity information is saved on the fifth drive. With SAS disks, the video and audio data is striped over the first 4 or 5 drives while the parity information is saved on the fifth or sixth drive. If one drive is damaged, the Video Raid can use the parity information to recover the missing information, so that operation can continue seamlessly without bandwidth loss.
For more information on online rebuild, refer to the section dedicated to this subject in the XS Software Technical Reference manual.
1.7.9 INTERPOLATION
The playing back of smooth slow motion pictures carries specific issues: since some fields must be repeated at regular interval to provide the video at the playback speed required by the operator, parity violation appears regularly on the output video signal. This issue is specific to interlaced formats (525i, 625i and 1080i) and does not concern progressive formats (720p and 1080p).
If O and E represent respectively the odd and even fields of a standard video signal (50/60 Hz), we have:
The original video signal: O E O E O E O E O E O E O E O E The output video signal at 50% speed: O O E E O O E E O O E E O O E E The output video signal at 33% speed: O O O E E E O O O E E E O O O E The output video signal at 25% speed : O O O O E E E E O O O O E E E E Fields with parity violation are shown in bold, underlined letters. As it appears
from the above table, whatever the playback speed (with the exception of the normal 100% playback speed), a number of fields violate the normal parity of the output signal. This parity violation induces a 1-line shift of the field, resulting in a vertical jitter of the picture. The jitter frequency depends upon the chosen playback speed.
To avoid this phenomenon and provide a stable output picture, EVS developed 2 types of line interpolator: 2-line and 4-line interpolators. The interpolation process can be enabled or disabled by the operator on all EVS slow motion systems.
Issue
10.04.A
EVS Broadcast Equipment SA – January 2011
25
2-LINE INTERPOLATOR
The 2-line interpolator actually generates a new field, when the original field is in parity violation. Each line of this new field is calculated by a weighted average of the 2 neighboring lines. This process solves the problem of parity violation and vertical jitter, but the drawback is a reduction of the vertical resolution on the interpolated fields, that appear unfocused. Another by-side effect is the alternation of original fields (perfectly focused) and interpolated fields (unfocused), resulting in a "pumping" video signal.
4-LINE INTERPOLATOR
The 4-line interpolator uses a more sophisticated calculation based on the 4 neighboring lines. By using suitable coefficients for the weight of each line in the resulting calculation, we apply this interpolation to all fields
. The final result is a permanently, slightly unfocused picture. The advantage is a stable output signal with no jitter and no "pumping", but the vertical bandwidth is even more reduced.
The interpolator is of course always disabled at 100% playback speed, because there is no parity violation.
EVS use the same techniques with the Super Slow Motion disk recorder, working with all models of Super Motion cameras (150/180 Hz). The only difference between the processing of Super Motion and normal scan (50/60 Hz) signals is that the interpolator is always
disabled at 33% playback speed, because the Super
Motion signal does not cause parity violation at this particular speed. Whatever the choice, the resulting picture is thus always a compromise between
stability and resolution. With EVS systems, the operator always has got the choice between any of the 3 above described techniques: no interpolation, 2-line interpolation or 4-line interpolation. Even if the operator chooses to use the interpolation, this process will be automatically disabled when not necessary (100% playback for 50/60 Hz signal, 33% and 100% playback for 150/180 Hz signal).
Note
All professional VTRs use line interpolation in PlayVar mode to avoid

2.7 CONNECTING MULTIPLE EVS VIDEO SERVERS ON XNET
The XNet network may be composed by several EVS video servers all connected with a 75-Ohm coaxial cable (BNC).
The exchange between systems is operated through the SDTI interface at 540 or 1485 Mbps.
On XS servers there is one pair of SDTI connectors: XNet[2] Non-Relay connectors that can be used at 540 or 1485 Mbps.
The SDTI loop is closed only when the Multicam software is started. It is therefore recommended to use XHub when using Non-Relay connectors to avoid network interruptions.
Note
If an XS ‘SAS’ must be connected to other XT2 or XS servers with SCSI disks, these servers must run at least Multicam version 10.01.67.

2.7.3 REQUIRED CONDITIONS TO SET UP AND RUN XNET
1. All systems on the network must be XT[2], XT[2]+, XS, or XF[2], XStore[2] or
XHub[2].
2. The SDTI advanced option code (for network client, master or server modes)
must be validated in the options list.
3. They should all be running compatible software version. A warning message is
displayed when trying to connect an EVS video server with a software version that is not compatible with the network server.
4. The following parameters must be similar on all systems :
a. SDTI Speed (usually 540Mbps or 1485Mbps, from Hardware Configuration
menu)
b. Number of cli ps
5. Network Type must be set to “Server” on 1 EVS video server (and only 1) on
the network. The others must be set to either “Master” (to share clips and view others’ clips) or “Client” (to share clips only).
6. A different network number must be specified for each EVS video server
system that you want to connect to the network. If the same network number is assigned to 2 different systems, the second one will not be able to connect and a warning message will be displayed.
7. All EVS video servers must be connected with a good quality BNC 75Ohm
cable to form a closed loop. Connect the SDTI OUT connec tor of the first EVS video server to the SDTI IN connector of the second one, etc until the loop is closed by connecting the SDTI OUT connector of the last EVS video server to the SDTI IN connector of the first one. The SDTI loop must be closed at all times during network operation. If for any reason the loop is open, all network communication will be interrupted and all systems will automatically switch to stand-alone mode. When the loop is closed again, network operation will resume automatically. This problem can be avoided or lim ited using EVS XHub SDTI hub.
8. The distance shown in the table below is the maximum cable length between
two active EVS servers, o r 2 SDTI reclockers, on an XNet SDT I network, using a single piece of cable between 2 servers or 2 reclockers. Intermediate connectors, patch panels, etc., might degrade these figures. Depending on the number of servers connected on the network, the location of the master server, the presence or not of an XHub SDTI hub, the actual maximum values may be higher than indicated. If longer distances between servers are required, SDTI to Fiber converters can be used, allowing distances over thousands of meters if necessary. EVS has validated the following SDI-Fibre conve rters:
a. Stratos Lightwave Media Converter TX/RX VMC-T-H-2/VMC-R-H-2
(www.stratoslightwave.com) b. Telecast TX /RX292 (www.telecast-fiber.com) c. Network Electronics SDI-EO-13T (electrical to optical) / SDI-OE-S (optical

Note
When reclockers are used, the total delay induced by these reclockers between 2 active servers on the network may not exceed 15μs.
2.7.4 STARTING XNET
1. When all above conditions are fulfilled, turn on the “Server” EVS video server and start the Multicam application.
2. Turn on all “Masters” and “Clients” EVS video servers, and make sure the Multicam application is started on all of them. They should see the “Server” on the network and they will connect automatically. Connection takes a few seconds (usually between 2 and 5 sec) for each EVS video server.

2.7.5 XNET PERFORMANCES & TROUBLESHOOTING
1. With the default settings, 10 real-time transfers can be achieved on the network with standard definition pictures in normal conditions, and 3 real-time transfers with super motion pictures. Copy of a clip between 2 servers on the network can be made up to 5 times faster than real time, depending on network load.
With high definition pictures, these numbers are redu ced to 3-4 real-time transfers and copy clip 2 times faster than real time. These performances are also limited by the disk bandwidth available from the EVS video server wher e the clips are stored. If the EVS video server “owning” the clips is doing multiple playbacks at the same time, freezes can occur on the remote EVS video server using those clips. Priority levels have been implemented to maximize network bandwi dth efficiency: PLAY requests have a higher priority than SEARCH/BROWSE reques ts, which in t urn have a higher priority than COPY requests. Note that “Live” (E2E) mode on a remote record train has the same prior ity level as a SEARCH/BROWSE request.
2. Note that when working at 1485Mbps or 540Mbps, only passive SDI routing equipment may be used. The use of active SDI equipment should be avoided, because they could cause additional line delays and prevent the proper operation of XNet.
3. If the start-up of the network at a specific speed does not work properly and all machines are apparently configured properly and the Multicam is actually started on all of them, this can be due to the fact that the selected cables to connect all EVS video servers together are not suitable or too long to operate at such a speed. You can decrease the speed of the SDTI network on all machines and try working in this mode. The number of simultaneous real-time transfers you can achieve is of course reduced.
4. While working at 1485 Mbps, if the connection cannot be established, please make sure that all equipments are set to the same speed and connected to the non-relay connectors. All equipments should be started if not connected to an XHub.
5. It is recommended to use XHub if the network speed is set to 1485 Mbps.
6. Once the network has been established, if the system acting as the network server is disconnected or shut down, another system will automatically be assigned to act as a new network server. The switch is automatic. The next machine to be automatically assigned as new network server is the one with the highest serial number in the SDTI network.

2.8 GIGABIT NETWORK
2.8.1 FUNCTIONAL OVERVIEW
The Gigabit connection makes it possible to transfer video and audio material from the XS servers to external systems via the TCP/IP network.
The external systems can be the follo wing:
• A storage system or an archiving system, such as XStore or XF[2].
• A non-linear Editing system, such as Xedio, Apple Fina l Cut Pro or Avid.
However, the external systems cannot read the raw files coming from the XS servers. For this reason, XTAccess is used as a “ga teway” between the XS and the IT world. It takes up the role of gateway used so far by XFile/XStream as it creates file formats compliant with external systems.
XTAccess is directly connected to the XS servers through the Gigabit network via an FTP client. It runs on an XP workstation and is mainly controlled by the external systems (no user interface) via XML files or other processes.
The Gigabit connection fulfills the following functions in relation with the XS servers:
• Backup of clips fro m an XS server
• Restore of clips to an XS server
• Transfer of clips between se rvers
The sections below briefly present the backup and restore of clips through the Gigabit connection. Please refer to the XTAccess user manual for full information about the possible workflows with third-party systems.
Issue
10.04.A
EVS Broadcast Equipment SA – January 2011
45
2.8.2 BACKUP OF CLIPS
The following schema shows how the backup of clips is performed with the Gigabit connection and XTAccess:
Workflow
1. An external system, for example IP Director, sends an XML file to XTAccess to request the backup of a given clip created on an XS server.
2. XTAccess processes the XML file: a. It gets the clip content that has to be backed up from the XS server. b. It generates a backup file of the clip in the format specified by the external
system (no transcoding feature, only native codec). The following formats are supported: EVS MXF, AVI, Avid MXF OPAtom, MXF OP-1A, Quick Time, Quick Time Ref (depend ing on the video codec).
c. It stores the backup file in the target folder specified by the external
system. The metadata on the clip are either included in the file (in EVS MXF) or sent via an XML file.

XS Series DISK RECORDER – Version 10.04 - Hardware Technical Reference

46
2.8.3 RESTORE OF CLIPS
Only clips having one of the following formats can be restored: EVS MXF, MXF OP-1A or Quick Time (depen ding on the video codec).
The restore process can be set up in two different ways:
• via XML file sent by the external application.
• via folder scan.
The following schema shows how the restore of clips is performed with the Gigabit connection and XTAccess:
Workflow (Restore via XML File)
1. An external system (which can generate XML files for restoring clips, for example MediaXChange or IPDirector) sends an XML file to XTAccess to request the restore (copy) of clips from an archiving or backup system to a given XS server.
2. XTAccess processes the XML job: a. It gets the clip file to restore f rom the external system. b. It restores, i.e. copies, the clip on the XS server specified in the XML file.
Workflow (Restore via Folder Scan)
1. Based on the parameters defined in XTAccess, this application scans specific folders on external backup or archiving systems.
Issue
10.04.A
EVS Broadcast Equipment SA – January 2011
47
2. When a clip file has been completely written to the scanned folder, XTAccess creates a copy of the clip on the XS server specified in the XTAccess parameters.
The restored clip receives a new UmID and LSM ID:
o Multicam automatically assign s a UmID to the restored clip. o A start LSM ID is specified in XTAccess and incremented as defined for
each new clip that is restored in order to find an empty location on the XS server.
The restored clip contains the clip metadata.
3. The restored clip is moved from the scanned folder to one of the following subfolders on the external archiving or backup system:
o \Restore.done\: folder where the files are moved to when they are
successfully restored.
o \Restore.error\: folder where files are moved to when they failed to restore.
2.8.4 IMPORTANT RULES
Gigabit networks including EVS servers need to abide by the following rules:
• The material used on GigE networks with EVS servers need to support jumbo
frames.
• Both GigE ports of an EVS server need to be defined on different sub-
networks.
• Teaming between the GigE1 and GigE2 ports is not possible.
• This is not possible to implement failover through the GigE network.
• The GigE port available on the MTPC board (PC LAN) is a 100Base-T port.
This is used for monitoring purposes (XNet Monitor) or for the communication with other applications (LinX). This can be in the same sub-network as the GigE port.
2.8.5 SWITCHES
SUPPORTED SWITCHES
All switches used on the GigE networks of EVS systems need to support jumbo frames (Ethernet frames with more than 1,500 bytes of payload).
Three models of 19-inch Gigabit switches have been validated for use with EVS’ workflows:
• HP Procurve 2510G-24
• Cisco Catalyst 2960G-24TC
• Cisco Catalyst 3750E-24TD/3750E-48TD

COMPARISON
The HP P rocurve 2510G-24 and Cisco Catalyst 2960G-24TC can be used for small setups where no inter-VLAN routing is needed.
On larger setups, both Ethernet ports of the XS servers or/and several ports on the XF[2] are often used to increase the bandwidth or to allow redundancy. Since both Ethernet ports of an XS server cannot be used on the same sub-network, virtual LANs need to be created. To allow the transfer of packets between the virtual LANs, layer 3 switches are required. You need to select a layer 3 switch that is able to route jumbo frames.
A switch of the Cisco Catalyst 3750E series should be used on larger setups as they support jumbo frames, allow traffic to be routed between different VLANs and provide stacking capabilities.
The following table gives an overview on the supported switches:

HP switches are not compatible with Cisco's proprietary protocols (ISL, PagP, PVST, etc.) which could be a problem for integration in some legacy Cisco environment. However, such a case is quite unlikely to arise and most of the time workarounds can be found.
The stacking possibilities of the Cisco 3750E series permit to have fully active LACP teams for redundancy t o the hosts.

2.9 REDUNDANT IPDP SERIAL LINK
The IPDirector communicates with the XS server via one serial link. If that link fails, the XS server can no longer be controlled by any IPDirector.
From Multicam version 10.01, a failover mechanism has been put into place. This mechanism w ill switch the IPDirector link from one port of an XS server to another port on another XS server.
To ensure the failover, the backup links between IPDirector workstations and the XS servers need to be physically cabled to a second RS422 port, as shown on the following schema:
Active RS link
Redundant RS link
IPDirector IPDirector
XS 1 XS 2 XS 3 XS 4
The serial link redundancy will ensure that there is no single point of failure in the setup. However, you need to put into place a thoroughly thought through IPDP configuration for the SynchroDB to continue working correctly. This can be achieved, for example, by defining an IPDirector workstation in Network mode.

3.1 BOARDS AND SLOT CONFIGURATIONS
The XS server contains all EVS developed boards. The XS servers can be fitted with COHX or V3X video boards. The board configuration will slightly vary depending on the type of video board used. The XS server is available in a 5U frame, whatever the video board.
Important
It is not allowed to mix COH X and V3X boards on the same EVS serv er.

3.2 VIDEO AND REFERENCE BOARDS
3.2.1 XS COHX BOARD
DESCRIPTION
The XS COHX board is divided in 3 parts: COHX base (centre front and back), COD A module (front left), and COD B module (front right).
COD A and COD B modules are the actual CODEC modules, each of them being able to be configured by software either as an encoder (for a record channel) or as a decoder (for a play channel). There are 3 hardware versions of COD modules: SD only, HD only, or HD/SD. They are clearly identified by the sticker at the front of the board.
There are 2 versions of the COHX base: one with genlock, one without genlock. The genlock model can easily be identified by the presence of 3 quartz synthesizer at the back of the board, on the right-hand side, and by the presence of the GLK and PSU OK LEDs on either side of the DIN connector at the centre front of the board. Note that a COHX board with genlock must
be installed as COHX #1 in first position (slot 2) in an XS system. A COHX board wit h genlock can never be installed in any other slot, and thus cannot be used instead of COHX #2. Doing so will result in conflicting electrical signals inside the system.

3.2.2 V3X BOARD “DUAL POWER”
Important
It highly advised not to remove a V3X board from the EVS server. Should you have to do so, manipulate the board very carefully, making sure it is not exposed to mechanical or electric shocks.
DESCRIPTION
The V3X board is divided in 3 parts: a base board identified as COHX base (rear section and center extension), and two modules identified as COD A V3X (front left), and COD B V3X (front right). The COHX base is the same as the COHX board, whereas the COD A and COD B modules are spec ific to the new V3X board.
The COD A V3X and COD B V3X modules are the actual CODEC modules, each of them being able to be configured by software either as an encoder (for a record channel) or as a decoder (for a play channel). The COD V3X modules are SD, HD and 3 Gbps capable.
From Multicam 10.04, t hey support the following new features:
• Full resolution 3D HD on a single V3X module (dual link HD SDI or single link
3Gbps)
• 1080p 50/59.94Hz video standard on a single V3X module (dual link HD SDI or
single link 3Gbps)
There are 2 versions of the V3X board: one with genlock, one without genlock. The genlock model can easily be identified by the presence of 3 quartz synthesizer at the back of the COHX base board, on the right-hand side, and by the presence of the GLK and PSU OK LEDs on either side of the DIN connector at the centre front of the board. Note that a V3X board with genlock must
be installed as V3X #1 in
first position (slot 2) in an XS server. A V3X board with genlock can never
be installed in any other slot, and thus cannot be used instead of V3X #2. Doing so will result in conflicting electrical signals inside the system.

GENERAL CONNECTIVITY ON THE V3X COD A AND COD B MODULES
This section describes the connector assignments and layout for the video standards SD 525i, SD 625i, HD 1080i and HD 720p.
The specific connectivity for HD 3D/1080p Dual Link and 3D/1080p single link 3Gbps is described in dedicated sections .
Changes in Connector Assignments from Multicam 10.04
On XS servers equipped with DualPower V3X video codec boards, the assignment of video connectors on the rear panel has been modified to reflect the new configurations available from Multicam 10.04:
Consequently, the following changes are applied to connectors:
• The center left connector of a group of video connectors on the rear panel can
be connected to either the J1 or J5 connector on the V3X module. It should be connected to J1 if monitoring (CVBS or SDI) is required in SD or
HD mode. Apply caution if you need to move the corresponding cable between J1 and J5
connectors on the V3X module: do not apply excessive traction or pressure, and make sure pressure or traction is applied in the correct alignment of the connectors, never sideways.
• The J3 connector, previously labelled ‘SD OUT’ and located on the center left
position, is now labelled ‘OUT B’ and located at the bottom right position. From Multicam 10.04, it is the output for the left eye or link 2 when working
with 3D or 1080p dual link formats.

3.4.3 EXTERNAL RAID ARRAY FOR XS SERVERS
Two types of external RAID array can be used according to the model of internal disks which equip the XS server:
• XT-HDX array for SCSI dis ks
• SAS-HDX for SAS disks.
XT-HDX EXTERNAL RAID ARRAY
The XT-HDX is an external disk storage containing up to 15 SCSI disks. It is connected to the XS server via a dedicated SCSI cable on the backplane of the server.
Necessary equipment
• XS with XT-HDX connector on the back plane and MT 5D_LNK board
• XT-H DX external disk storage
Important
An XS server cannot work simultaneously with an internal RAID array (MT5D) and an external RAID array (XT-HDX). When an XS server is equipped with the XT-HDX external disk storage, the MT5D internal RAID is replaced by the MT5D_LNK board. This replacement has to be done by EVS staff.
Installation and operation
1. Both the XS server and the XT-HDX need to be switched off.
2. The XT-HDX expansion chassis must be located immediately above the chassis
of the XS server.
3. Connect the XT-HDX to the server only with the external SCSI cable provided
by EVS (see sc hema and picture)
4. Disks in the XT-HDX rack are hot-swappable. However, a disk can only be
extracted from the rack when it has been stopped by the software application (disk led blinking slowly red with a 4-second cycle)

It is therefore normal to see activity only on 5, 10 or 15 disks depending on how much material (clips and record trains) is stored on the server.

How to replace a Disk
Before replacing a disk, ensure that the software application has disconnected and stopped the disk. In this case, the disk LED is blinking slowly red with a 4-second cycle.
1. When the disk is stopped, disconnect the canister.
2. Replace the disk in the canister.
3. Put the canister back sliding it to the bottom of the frame. The LED on the canister should first blink rapidly red with a 3-second cycle while
the disk is being mounted. Then, it should blink green.

SAS-HDX EXTERNAL RAID ARRAY
The SAS-HDX is a 2RU external disk storage containing up to 24 hot-swappable SAS disks, with a minimum of 5 disks. External storage can be used with or without internal storage.
It is connected to the EVS server via a dedicated SAS cable on the rear panel of the server, provided that the X-ESAS connection module has been placed inside the server.
Necessary equipment:
• XS with SAS-HDX connector on the rear panel.
• Multicam version 10.03 or later
• SAS-HDX external disk storage
LEDS on External Array
For each disk, a blue LED and a red LED are present.

Note on Disk LEDs Activity
When starting from a clean disk array (after a “Clear Video Disks” from the EVS maintenance menu), the XT[2]+ server is recording first on RAID #0 until this one is full, then on RAID #1 and finally on RAID #2. It is therefore normal to see activity only on some disks depending on how much material (clips and record trains) is stored on the server.
Sound Alert on External Array
When a fan or a power supply unit has failed on an external array, a sound alert is given and can be stopped by pressing the Mute button on the array.

3.5 MTPC BOARD
3.5.1 INTRODUCTION
The function of the PC board is mainly the control of the Video hardware and to interface the peripheral equipment (i.e. remote controller) with the Video hardware.
One type of MTPC b oard can be used:
• Revision A2/A4 with COMMEL HS870 mot herboard.
In standard configuration the PC hardware is composed by:
• One mounting PC board, with serial ports, LTC reader and generator, is
controlled by the motherboard.
• IDE System Hard disk: the IDE disk drive is used for storing the EVS software
and the DOS operating system. Neither audio nor video data is saved on this disk. The capacity of this drive may vary depending on market availability, but the system partition is always set to 1GB. The remaining capacity of this drive is not used.
• 64/128MB SDRAM modified. The SDRAM used has been modified to suit the
system requirements. Please contact EVS support for RAMs upgrade. Do not use standard PC RAM modules.

BOARD CONFIGURATION
HPOL, VPOL and ENVS are used to configure the composite sync generator used in TV mode (no effect if XS is only used with a VGA moni tor).
The HPOL jumper can be used to invert or not the VGA HS signal (Horizontal Sync) to generate the composite output signal (TV mode).
The VPOL jumper can be used to invert or not the VGA VS signal (Vertical Sync) to generate the composite output signal (TV mode).
The ENVS jumper can be used to enable or not the presence of the VGA VS signal (Vertical Sync) in the composite output signal (TV mode).
If the TV mode is used, these jumpers must be set-up according to EVS recommendations, which depend on software version and CPU board model/revision:
With MTPC board A2/A4, set up the jumpers as follows:
• HPOL=On; VPOL=Off; ENVS=On
REMOTE RESET jumpers are available to designate the remote(s) from which the RESET command can be sent.
This command resets the whole system: PC and video hardware.
Important
This jumper should be removed if the device connected to the RS422
port is NOT an EVS controller. Maximum voltage on pin 5 of an RS422 port of the XS server should not exceed 5 Volt when the corresponding
jumper is engaged. Applying a higher voltage on pin 5 when the
corresponding jumper is engaged will result in permanent electronic damage to the board.
