2 Summ ary

This chapter gives an overview of the HERMES DXD.

2.1 Conne cting the graphical controller and the projection cubes

HERMES DXD is equipped with two digital input connectors (Digital In 1, Digital In 2) and two digital output connectors (

Digital Out 1, Digital Out 2).

The output connectors can be routed to any input connector, resulting in the following fields of applications:

Hermes DXD as multiplexer

The connection of the projection cubes to different types of graphical controllers via HERMES DXD allows controlling the Display Wall by different operating systems. Some cubes or the entire Display Wall can alternatively be used as Windows NT desktop or as root window (X Window system).

Redundancy

Some fields of application require the connection of the projection cubes to identical graphical controllers: In a case of malfunction of one graphical controller it is immediately switched to the other graphical controller. This redundancy guarantees a permanent availability of the Display Wall.

Splitter

It is also possible to apply one signal to both outputs and thus display the identical information on two different projection cubes.

Repeater

To increase the distance between graphical controller and projection unit, HERMES DXD can be used as a two channel repeater.

2.3 Remot e Control

ERMES DXD is controlled by a serial interface. The remote control is integrated in X Window

(see

7.3.3 User’s Manuals) and available as application for Windows NT/2000/XP (HERMES REMOTE-

ONTROL). The protocol is accessible for individual applications.

The general concept of remote control, i. e. cabling, connection settings and protocol are described separately in chapter

3.1.2 The Bac k Panel

The back panel of your HERMES DXD looks like this or similar:

A Main Switch B AC In C AC Out

Figure 3-3

The Main Switch [A] is for switching HERMES DXD on and off. If the 0 is visible on top of the switch, the device is switched off, and it can be switched on by pressing the switch.

The

AC In socket [B] is for connecting to a power supply as specified in section 7.1.2 Power Supply.

The AC Out socket [C] is for connecting further devices (of type HERMES DXD only!) to the power supply.

AC Out is connected directly to AC In and is live as soon as AC In is connected to a power supply.

Up to max. ten HERMES DXD devices can be put on top of each other. Thus you can group the devices into towers next to each other, e. g., in the same order as the projection cubes are arranged.

To protect HERMES DXD from overheating, the air supply openings in the case must not be covered! If you group the devices into towers standing next to each other a space between the devices not less than 10 centimeter must be kept!

3.2 Native device settings (default settings)

Hermes DXD has auto switch capabilities: in case there is no signal present at the input routed to an output, the output may switch automatically to the other input. Per default, this auto switch functionality is enabled. If desired, it can be deactivated, cf. Enabling/Disabling auto switch

Having two graphic channels connected to HERMES DXD, and none of them specified as input source, the channel connected to nected to

DIGITAL IN 2 is selected as signal for DIGITAL OUT 2.

After cabling is complete you can switch on the device with the main switch on the back panel. Switching between the two graphical controllers is done by means of the remote control (see chapter

Switching commands

3.3 DDC C a pability

ERMES DXD has DDC capability, i.e. it reads the timing of the connected projection module.

It is mandatory that the projection units connected to the two outputs of a Hermes DXD are all of the same type, e.g. OverView D

HERMES DXD scans the outputs to get the timing information of the connected projection modules. As soon as it gets a timing, the scan procedure is finished, and the detected timing information is stored and used for both inputs!

The graphical channel connected to

DIGITAL IN 1 and the graphical channel connected to DIGITAL IN 2

during the boot procedure look up once the timing of the input and adjust their settings accordingly. To ensure that HERMES DXD provides the timing information already when booting the controller it is recommend to first switch on H

ERMES DXD, and then switch on the controller.

5.3

Hermes DXD scans the timing of the projection module whenever a connection is made. If the timing changes, e.g. a projector is disconnected and a different one connected, Hermes DXD "knows" it immediately and adjusts the information stored in DIGITAL IN 1 and DIGITAL IN 2 accordingly. The graphic card looks up the timing information ONLY during the boot procedure. Thus replacing a projector with a different timing requires re-booting the graphical controller to get the correct settings!

3.4 Cabling

This block diagram gives an overview about the cabling of H

ERMES DXD

The cabling must be done before switching on HERMES DXD or any other system components!

Signal cables are available in different types (fibre or copper), different interfaces (PanelLink-to-DVI, DVI-to-PanelLink, DVI-to-DVI) and different lenghts. Therefore they are not included in the delivery of Hermes DXD, but can be ordered according the actual requirements, please refer to

3.4.1 Power S u pply

Check the power rating on your outlet before connecting HERMES DXD to a wall outlet or to a power strip. See section specification. Contact your facilities manager or a qualified electrician if you are not sure what type of power is supplied to your building.

HERMES DXD is designed to operate with single-phase power systems having a grounded neutral conductor. To reduce the risk of electrical shock, do not plug into any other type of power system.

7.1.2 Power Supply for the necessary technical

Make sure that the main switch is in the off position. Plug in the female end of the power cord into

AC In.

ERMES DXD offers a power outlet AC Out for connecting another HERMES DXD. When operating

more than one H

ERMES DXD then up to 10 devices in total may be connected in series. Thus a clear lay-

out of cabling is possible.

AC Out is connected directly to AC In and is live as soon as AC In is connected to a

power supply.

Only Hermes DXD devices are allowed to be plugged into the AC Out of a Hermes DXD.

3.4.2 Digital I n put and Output

HERMES DXD has DVI interfaces. Depending on the type of graphical card and/or the type of projection module, the following kind of cables are required: DVI-to-DVI, DVI-to-PanelLink, PanelLink-to-DVI. The DVI-DVI cable is available as copper cable (length up to 10m) and fibre cable (length up to 100m).

The DVI-to-PanelLink and the PanelLink-to-DVI adapter are exclusively available as copper cables. There are no visible differences between these two adapter. To know which is which, please have a look at the identification label on the adapter and look up the product number in the table below:

3.5 Operat ing Hermes DXD

After the cabling is done, you can switch on your system. In order to provide the graphic cards with the correct timing, it is mandatory that H

ERMES DXD is switched on before booting the controller!

The projection engines can be switched on or off: the timing information is received via the data cable as soon as the connection is established.

Controlling

HERMES DXD is done via RS232 Remote-Control. Either the commands are sent via a dedi-

cated protocol (RFTP = Remote File Transfer Protocol), or via the graphical user interface of H REMOTE CONTROL, a software tool to intuitively switch the required input to the desired output. The graphical user interface is described in the user manual HERMES REMOTE CONTROL. In this manual, the open protocol is explained.

ERMES

4 Remo te Control

The remote control is a system for scanning and controlling single devices of Barco Display Wall. As a certain class of devices H control the respective input can be switched to a desired output.

This chapter describes the basics of remote control as cabling, protocol and addressing procedure for H

ERMES DXD.

ERMES DXD can be scanned from a central computer. By means of remote

4.1 Cabling

A remote control system consists of three different components:

 remote control master (

 remote control slave (

RCM)

RCS)

 remote control connection

The

RCM is the central computer which controls the slave devices RCS. All control messages are gener-

ated by the

RCS and directed to the RCM without request.

All

RCS are connected in series. Messages sent from the RCM are passed on by an RCS to the next RCS,

and finally return to the

RCM, addressed to a certain RCS device and sent on. Incorrect messages are processed by a

RCM. The messages run in a ring.

The RCM must be connected to each RCS in series. For a clear lay-out of the cabling the different types of

RCS should be arranged into blocks within the ring, e. g. all HERMES DXD first, then all illumination

units.

4.1.1 Cabling of Hermes DXD (number of devices < 20)

The serial interface of the RCM (COM1) must be connected to the Remote In socket of the first HERMES DXD. Each following HERMES DXD (Remote In) is connected to the previous HERMES DXD (Remote

Out

). This kind of connection is called daisy chain.

Remote Control Interfaces

Daisy chain cabling of devices

Figure 4-1

Figure 4-2

A shorting plug must be inserted into the REMOTE OUT socket of the last device in order to close the ring.

If the internal logic control of a RCS detects an error, or if a device is switched off, the input and output of its remote control interface are short-circuited, such that all other remote control devices can still be addressed. Pay attention that during the addressing procedure all

RCS are active, in order to prevent

confusion in the addresses

4.1.2 Cabling of Hermes DXD (number of devices > 20)

If there are more than 20 devices a distribution panel has to be used. Then the cabling looks like this:

remote control cabling by use of a distriubtion panel

Remote control cabling is available in various length and with adapters for connecting to different devices. See section

7.3.2 Remote Control for the parts list, please!

4.2 Definit ion of Protocol

4.2.1 Connec t ion Settings

The physical medium for data transfer is based on a RS-232-C interface:

signal level RS-232-C

baud rate 9,600 baud

data bits 8

parity bits none

stop bits 1

max. distance 25 meters between two active members (RCS or RCM)

4.2.2 Commu n ication

The devices of HERMES DXD are numbered consecutively. A certain device is addressed by means of this number. H quested device receives the command. The command returns unprocessed to the

ERMES DXD executes the received command and passes on the message until the re-

RCM if no HERMES

DXD has been addressed. In case a device has been addressed, and the command is valid, the command is executed, and the device sends an acknowledge ACK to the master. In case a device has been addressed, and the command is invalid, the device passes the command unprocessed to the master and adds "

EP" (Error Protocol) to the command.

Basically there are two kind of commands: commands which are answered by an acknowledge including a status information and commands which are passed on or answered without status.

4.2.3 Structu r e of Messages

The messages consists out of a RCS-independent and a RCS-dependent layer. The RCS-independent parts are interpreted the same by all types of devices. The mands for a certain type of

RCM: the message body.

RCS-dependent parts contain specific com-

A message has the following structure:

These are the elements of a message in detail:

STX The control character STX (Ctrl-B) is the beginning of a

message. All previously received characters are ignored and are not sent on. (Ctrl-B is displayed as  in most terminal applications.)

<TYPE> 1 byte ASCII

declares the type of class of addressed RCS.

<ADDRH><ADDRL> 2 bytes ASCII decimal

addresses the n-th RCS within a class of the specified type.

<Body> type-dependent part of the message, e. g. a command <CHKH><CHKL> 2 bytes ASCII decimal

is the sum over all fields from <TYPE> to <Body>. The checksum is evaluated by the recipient.

ETX The control character ETX (Ctrl-C)is the end of a message.

(Ctrl-C is displayed as  in most terminal applications.)

Four different types of messages are used:

Table 4-2

commands RCM sends command messages to a RCS.

acknowledge RCS sends responses to the RCM after having executed the command

responses RCS sends responses to the RCM on request.

interrupts RCS reports errors to the RCM without request.

4.2.4 Acknow l edge

The acknowledge is composed of the command the RCS has received and executed and the internal

Status Register.

An acknowledge has the following structure:

These are the elements of an acknowledge in detail:

STX The control character STX (Ctrl-B) is the beginning of a message.

All previously received characters are ignored and are not sent on. (Ctrl-B is displayed as  in most terminal applications.)

<TYPE> 1 byte ASCII

declares the type of class of addressed RCS.

<ADDRH><ADDRL> 2 bytes ASCII decimal

addresses the n-th RCS within a class of the specified type.

<Body> type-dependent part of the message, e. g. a command <STATH><STATL> 2 bytes Hexa decimal

information about the internal Status Register

<CHKH><CHKL> 2 bytes ASCII decimal

is the sum over all fields from <TYPE> to <STATL>. The checksum is evaluated by the Remote Control Master.

ETX The control character ETX (Ctrl-C)is the end of a message. (Ctrl-

C is displayed as  in most terminal applications.)

4.3 How to calculate the checksum

The checksum is being evaluated from the recipient to make sure that the message received has not been corrupted. The checksum is a kind of sum over all fields from <TYPE> to <Body> or <TYPE> to <STATL> respectively (Acknowledge).

The checksum is calculated by transforming each character of the message into its ASCII code. The ASCII values are added, and this sum is converted into a hex number. The checksum uses the last two digits of this hex number. If the hex number consists of non-numeric characters, these characters have to be lower case characters. Example: Let's consider the addressing procedure. The command for the addressing procedure is



 m00Axx 







xx is the checksum to be calculated. The <TYPE> of the message is m, the <Body> 00A

message m 0 0 A

ASCII code 109 48 48 65

Summing up 270

converting into a hex number =10EH

character has to be lower case!

5.2 Reques t commands

Request commands can be sent from the RCS to the RCM or vice versa. The answer of a request command does not include the status information.

Command "R": Calling for Address

Description: Request for an address.

RCS that is not provided with an address will send requests for an address at regular

intervals. This message uses the command

R. It will be received by the RCM and signals the need

for a new addressing procedure.

Example: An

Message <STX> <TYPE> <ADDRH> <ADDRL> <Body> <STATH> <STATL <CHKH> <CHKL> <ETX>

RCS of class m asks for an address:

 m0 0 R bf

Command "A": Addressing Procedure

Description: Each member of the remote control chain must have a non-ambiguous address so that

functions can be specifically triggered in the individual devices. The addresses are assigned by an initial addressing message. Since all devices of a certain class have to be given a non-ambiguous address, and since at the beginning the many devices exist, the command uses as

<ADDRH> <ADDRL> the "00".

RCM does not know how

5.3 Switch i ng commands

The switching commands refer exclusively to the input and output involved. The other input and the other output are not affected!

These messages are processed in a straight forward way. The control character <STX> and the <TYPE> field are passed on immediately. Each recipient analyzes the content of the <TYPE> field . If the type does not match (e. g. the recipient is a member of the class d) the message is passed through. Otherwise if the type does match, the <ADDRH><ADDRL> fields are evaluated.

Again, if the address does not match the message is passed through. But if the address does match, and if the body contains a valid command and the checksum is correct, the command is executed, and the

RCS sends an acknowledge to the RCM.

In case the body is not valid, the message is sent back to the RCM, and EP is added (Error Protocol). In case the checksum is not correct, the message is sent back to the

5.4 Enablin g /Disabling auto switch

The auto switch functionality allows H

ERMES DXD to automatically connect an output to the other input

if there is no longer a sync signal on the input previous connected to this output. This functionality provides redundancy (inspite of a crash, there will be signal displayed on the projection modules), but sometimes it might be useful to disable this behavior (e.g. to check if all sources connected to the input are still ok). Per default, every H

ERMES DXD leaves production with the auto switch functionality enabled.

The status of the auto switch functionality can be derived from the status register.

Example: To get the information about the engineering change, the following command has to be

sent to the RCS:

v (read information) 4 (length of information) 23 (address of information (engineering

change))

In case it is the engineering change B, the

RCS answers via information:

5.7 Error m essages

Three different kind of errors might occur:

 The body is an invalid command

 The checksum is not correct

 The device cannot be addressed (it might be switched off…)

The information sent back to the RCM about these errors does not include the status register

Error Protocol "EP"

Description: Via this answer the RCM is told by the RCS of class m that the body has been an invalid

command.

Example: The

Message

RCM has sent a command x to the RCS.

 m0 2 y 48

Since the command y does not exist for an back to the

RCM, adds the extension EP (Error Protocol), and calculates the new check-

RCS of class m, the RCS sends this message

sum.

Answer

 m 0 2 y 48 EP 4 9 

Error Checksum "EC"

Description: Via this answer the RCM is told by the RCS of class m that the checksum has not beeen

correct.

Example: The

Message

RCM has sent the following command:

 m0 2 t 30

Answer

The correct checksum of the above command is 43. The sends the command back to the

RCM and adds the extension EC (Error Checksum)

RCS detects an checksum error,

 m 0 2 t 30 EC 2 e 

Original message is sent back to the RCM

Description: Via this answer the RCM recognizes that the desired RCS cannot be addressed (might be it

has been switched off…)

Example: The



The second command is passed to

Answer



If the internal logic control of a RCS detects an error, the input and output of its remote control interface are short-circuited, such that all other remote control devices can still be addressed. Pay attention that during the addressing procedure all active, in order to prevent confusion in the addresses.

RCM has sent the following command:

m0 2 t 43

RCS cannot be addressed, and via the closed remote control ring the original

RCM again.

m0 2 t 43

6 Broad cast addressing mode

This chapter describes how all Remote Control Slaves of a class are addressed simultaneously.

6.1 Structu r e of message

The messages consists out of a RCS-independent and a RCS-dependent layer. The RCS-independent parts are interpreted the same by all types of devices. The mands for a certain type of

RCM: the message body.

RCS-dependent parts contain specific com-

A message has the following structure:

These are the elements of a message in detail:

STX The control character STX (Ctrl-B) is the beginning of a

message. All previously received characters are ignored and are not sent on. (Ctrl-B is displayed as  in most terminal applications.)

<TYPE> 1 byte ASCII

upper case class code to specify broadcast addressing.

<ADDRH><ADDRL> 2 bytes ASCII decimal

in broadcast addressing it is always 00

<Body> type-dependent part of the message, e. g. a command <CHKH><CHKL> 2 bytes ASCII decimal

is the sum over all fields from <TYPE> to <Body>. The checksum is evaluated by the recipient.

ETX The control character ETX (Ctrl-C)is the end of a message.

(Ctrl-C is displayed as  in most terminal applications.)

Table 6-1

6.2 Proces sing a command in broadcast mode

As soon as an RCS recognizes that the command is sent in broadcast mode (e.g. in case of HERMES DXD, the second character is an upper case M), it immediately starts passing the entire message to the following

RCS. This ensures that all RCS of the Remote Control ring receive the command "at the same

time", thus being able to execute "simultaneously" the required action.

For broadcast commands, there is no acknowledge. However, the broadcast message will loop back completed and unmodified to the RCM and may be interpreted as acknowledge.

6.3 Comm ands for broadcast addressing

In principle, all commands can be sent in broadcast addressing mode, however, some of the valid commands are not very useful to be sent to all of the

RCS simultaneously.

The following table lists the commands for reasonable broadcasting addressing. For HERMES DXD it's the switching commands which are apt to be sent in broadcasting addressing.

command description

t selects input from first graphical controller

as signal for Digital Out 1

a selects input from second graphical controller

as signal for Digital Out 1

s selects input from first graphical controller

as signal for Digital Out 2

b selects input from second graphical controller

as signal for Digital Out 2

Example: If all RCS of class m are to select the input from the second graphical controller as

signal for

Digital Out 1, the RCM sends the following broadcast command:

Syntax

 M0 0 a 0e

<TYPE>

M (upper case, since the RCS are of class m and it is a broad-

casting addressing)

<ADDRH><ADDRL> in broadcast addressing it is always

The command passes all members of the Remote Control chain and is executed simultaneously by all

RCS. It then reaches unmodified the RCM.
