The invisible laser radiation may be in excess of the Accessible

Emission Limit (AEL) for a Class 4 laser. The invisible radiation can

be up to approximately 1.5kW CW per Prism FL Module in

normal operation and 2.3kW with a single fault. The wavelength of

this invisible radiation is in the range 1050-1250nm.

Additionally, the redPOWER Fibre Laser contains embedded

lasers that emit invisible laser radiation up to approximately 3.2kW

CW per Prism FL Module in normal operation and 4.8kW CW with

a single fault. The wavelength of this invisible radiation is in the

range 900-1000nm.

AVOID EYE OR SKIN EXPOSURE TO DIRECT OR SCATTERED

RADIATION.

Contact with direct or scattered laser radiation can cause damage

to the eyes, burn human tissue and start fires.

The optical connector shall be mounted in a protective housing

which prevents human access to laser radiation (including errant

radiation) in excess of the AEL for class 1, for example a housing

meeting the requirements of EN 60825-4.



The visible laser radiation is below the Accessible Emission Limit

(AEL) for a Class 2 laser. The wavelength of the visible laser

radiation is in the range 630 – 680nm.

DO NOT STARE INTO BEAM.

Laser emissions from the housing of the redPOWER Fibre Laser and the conduit of the

beam delivery optic are less than the AEL for Class 1 of IEC/EN 60825-14 with a single fault

providing that the fibre continuity monitoring system (FCMS) is correctly implemented by the

Laser Integrator.

5 Introduction

This document explains the command set and format of SPI Lasers’ redPOWER Fiber Laser

Serial Interface.

The physical layer has been implemented as an RS232 hardware interface.

The data link layer conforms to the High Level Data Link Control (HDLC) definition (ISO03309)

requirements.

Conforming with the HDLC definition ensures that :

Any data can be transmitted across the link (transparency).

The beginning and ends of frames are unequivocally recognized.

If an error occurs, the receiver will eventually resynchronise.

The receiver can detect communications errors in each frame it receives.

Another important feature is that transmit and receive packets both have packet identification

characters. This allows communications to run asynchronously. A missing response timeout

method is implemented in order to detect lost packets.





9

6 Protocol

6.1 Physical Layer

Standard 9 Way D-plug operating with signal levels defined by the RS232 specification.

The pin-out is shown below:

Pin RS232 Connections

2

3

5

Receive Data input (RX)

Transmit Data Output (TX)

GND

When connecting to a standard computer serial port, pins 2 and 3 should be crossed over at

the computer end.

The port should be configured to use a standard non-return-to-zero (NRZ) asynchronous

protocol with one start bit, one stop bit, eight data bits and no parity. The baud rate can be

selected using switches 7 & 8 on SW2 at the rear of a standalone laser, and on the control

card of a multi kW laser. The selectable rates are 9600 and 57600 baud.

SW2 -7 SW2 - 8 RS232 Baud Rate

OFF OFF 9600

ON ON 57600

6.2 Data Link Layer

The philosophy of the protocol is that there can be one master and up to 128 slaves. Each

salve has a unique address and will only respond when spoken to (i.e. no unsolicited

messages). The default laser address is 1. A single laser slave implementation will therefore

require no laser address set-up.





10

6.3 Frame Structure

The protocol frame is based around the "High Level data link control" (HDLC) definition

(ISO03309) with a flag byte at start and end, address byte, data bytes and 16-bit CRC

checksum.

The flag bit is 0x7E and with the default laser address of 1, a typical frame will be:

<0x7E> <0x01> <DATA> <CHECKSUM> <0x7E>

The "checksum" is a 16-bit CRC checksum utilizing the CRC16-ITU polynomial.

G(x) = x16 + x12 + x5 + 1, with an initialisation value of all '1's.

The inverted calculation is transmitted in each frame, LSB first, and is calculated from the

address and the data.

The sequence below shows a typical command together with calculated checksum.

Address Command LSB Checksum MSB Checksum

Eg. <0x01> <0x04> <0xBB> <0x50>

The transmitted data also has the flag character (0x7E) at the beginning and end.

6.3.1 16-bit CRC Calculation

Following are two examples of generating the CRC algorithm.

C Code Example

// ------------------------------------------------------------------

------

// Calculates CRC - returns calculated CRC

// ------------------------------------------------------------------

------

// Note: returned calculated CRC (fcs) should be appended to the end

of the command LSB first

// command_tx[] is string of characters on which checksum is to be

calculated(including board address)

// command_length is number of characters in command

int calc_fcs(void)

{

unsigned int j; // temporary variable

unsigned int fcs = 0xFFFF; // Calculated checksum

unsigned int count; // count of current

for(count=0; count < command_length; count++)

{

j = (fcs ^ (unsigned int)command [count]) & 15;

fcs = fcs >> 4;

fcs = fcs ^ (j * 4225);





11

j = (fcs ^ ((unsigned int)command [count] >> 4)) &

15;

fcs = fcs >> 4;

fcs = fcs ^ (j * 4225);

}

fcs = fcs ^ 0xFFFF;

return fcs

}

VB Code Example

Public Function Checksum(sDataString As String) As Byte()

'INPUT - Character string

'OUTPUT - 2 element byte array containing the LSB and MSB of the

checksum

Dim iCount As Integer

Dim lTemp As Long

Dim lTemp2 As Long

Dim lCharValue As Long

Dim lRunningResult As Long

Dim bResult(1) As Byte

lRunningResult = 65535

For iCount = 1 To Len(sDataString)

lCharValue = Abs(Asc(Mid$(sDataString, iCount, 1)))

lTemp = (lRunningResult Xor lCharValue) And 15

lRunningResult = lRunningResult \ 16

lRunningResult = lRunningResult Xor (lTemp * 4225)

lTemp = (lRunningResult Xor (lCharValue \ 16)) And 15

lRunningResult = lRunningResult \ 16

lRunningResult = lRunningResult Xor (lTemp * 4225)

Next iCount

lRunningResult = lRunningResult Xor 65535

bResult(1) = lRunningResult \ 256'MSB

lTemp = bResult(1)

lTemp2 = lTemp * 256

bResult(0) = lRunningResult - lTemp2 'LSB

Checksum = bResult

End Function

If the same calculation is performed on received data including the checksum, the calculated

value should be 0xF47. If it is not, the checksum is invalid and the data should be discarded.

6.3.2 Data Element

The data element of the command comprises a command number and any number of

Parameters as shown below.

<COMMAND NUMBER> <PARAM 1> <PARAM 2> …… <PARAM n>

Not all commands have associated parameters.





12

The "COMMAND NUMBER" is a single byte which selects the requested instruction.

The "PARAM"s is any number of single or multiple bytes containing any parameters required

by the particular instruction.

6.3.3 The Transparency Algorithm

The protocol requires the existence of a transparency algorithm to overcome the likely event

of data/checksum characters occurring with the same value as the frame character 0x7E. If

this situation were allowed to exist it would produce errors in the frame structure and make it

impossible for the slave devices to decipher the frame.

The transparency character is 0x7D.

If a frame character is detected, the transparency character is inserted preceding it and the

frame character has its sixth bit complemented.

Similarly if a transparency character is detected the same process needs to be implemented.

The transmitted data also has the flag character (0x7E) at the beginning and end.

The transparency algorithm is carried out in a serial fashion on all data and checksum bytes

before the frame is transmitted (i.e. Transparency algorithm is implemented after the

checksum has been calculated).

On receiving data the reverse process is carried out. The data being checked for transparency

bytes before any attempt is made to decode the data or checksum.

6.4 Communications Overview

The master packages the laser address, command and parameters into a data string and

calculates the crc-16 checksum. It converts any illegal characters using the transparency

algorithm and then transmits the block starting and ending with a frame character.





13

The laser receives the frame and reconstructs the original data and checksum. If the board

address does not match then the command is discarded. The CRC check is then carried out

and if it does not pass, the command is discarded.

If the CRC proves the validity of the frame then the command is performed and the slave

transmits a response. The response is a frame, using the structure described above,

containing a copy of the instruction sent and any requested readings or values in the

parameter section.

The response includes the laser address.

The master uses the same methodology to decode and validate the response frame before

taking any notice of the data contained within it.

If an error occurs the whole communication procedure is allowed to be repeated a limited

number of times. If the error condition persists, the master indicates a fault.

6.5 Further Code Samples

The following Visual Basic 6 code samples demonstrate the packing and unpacking of data

packets.

Example 1 - Build a transmit packet (uses checksum calculation shown above) :

Public Function BuildTransmitString(bData() As Byte, iDataLength As

Integer) As String()

'INPUT - Board address and command as bytes, data length as integer.

'OUTPUT - Transmit data string including checksum and any required

transparency characters

Dim ChecksumBytes() As Byte

Dim iCount As Integer

Dim iCount2 As Integer

Dim sResult() As String

Dim bTempArray() As Byte

Dim iMinimumTransmitStringLength As Integer

Dim sChecksumString As String

Const cFrameCharacter = &H7E

Const cRelacementFrameCharacter = &H5E

Const cTransparencyCharacter = &H7D

Const cReplacementTransparencyCharacter = &H5D

iMinimumTransmitStringLength = iDataLength + 4'Add 4 for start,

end and checksum characters.

ReDim sResult(iMinimumTransmitStringLength) 'Dimension array to

hold result

ReDim bTempArray(iMinimumTransmitStringLength) 'Dimension array

to hold temporary data

'Calculate the checksum

For iCount = 0 To iDataLength

sChecksumString = sChecksumString & Chr(bData(iCount))

Next iCount





14

ChecksumBytes() = Checksum(sChecksumString)

'Load the temporary array with the known data

For iCount = 0 To iDataLength

bTempArray(iCount) = bData(iCount)

Next iCount

'Tag on the calculated checksum

bTempArray(iCount) = ChecksumBytes(0)

bTempArray(iCount + 1) = ChecksumBytes(1)

'First character is a frame character

sResult(0) = Chr(cFrameCharacter)

iCount2 = 1

'Now fill in the data characters

For iCount = 0 To iMinimumTransmitStringLength - 2

If bTempArray(iCount) = cFrameCharacter Or

bTempArray(iCount) = cTransparencyCharacter Then

'Pad with a transparancy character if address is a

frame character

ReDim Preserve sResult(UBound(sResult) + 1)

sResult(iCount2) = Chr(cTransparencyCharacter)

iCount2 = iCount2 + 1

If bTempArray(iCount) = cFrameCharacter Then

sResult(iCount2) =

Chr(cRelacementFrameCharacter)

ElseIf bTempArray(iCount) = cTransparencyCharacter

Then

sResult(iCount2) =

Chr(cReplacementTransparencyCharacter)

End If

Else

sResult(iCount2) = Chr(bTempArray(iCount))

End If

iCount2 = iCount2 + 1

Next iCount

'Last character is a frame character

sResult(iCount2) = Chr(cFrameCharacter)

BuildTransmitString = sResult

End Function

Example 2 - Decode a response packet :

Public Function DecodeResponse(sData As String) As String

'INPUT - String response from laser

'OUTPUT - String stripped of frame and replacement characters

Dim iStringPosition As Integer





15

Dim sResult As String

Const cFrameCharacter = &H7E

Const cRelacementFrameCharacter = &H5E

Const cTransparencyCharacter = &H7D

Const cReplacementTransparencyCharacter = &H5D

For iStringPosition = 2 To Len(sData) - 1

If Asc(Mid$(sData, iStringPosition, 1)) =

cTransparencyCharacter Then

iStringPosition = iStringPosition + 1

If Asc(Mid$(sData, iStringPosition, 1)) =

cRelacementFrameCharacter Then

sResult = sResult & Chr(cFrameCharacter)

ElseIf Asc(Mid$(sData, iStringPosition, 1)) =

cReplacementTransparencyCharacter Then

sResult = sResult & Chr(cTransparencyCharacter)

End If

Else

sResult = sResult & Mid$(sData, iStringPosition, 1)

End If

Next iStringPosition

DecodeResponse = sResult

End Function

Example 3 - Check validity of response packet (uses checksum calculation and response

decode routines shown above). Code snippet only :

If Asc(Left$(RxTxt, 1)) = cFrameCharacter And Asc(Right$(RxTxt,

1)) = cFrameCharacter Then

'Unpack the response by removing and frame and replacement

characters

sResponseData = DecodeResponse(RxTxt)

'Verify that the checksum is correct

bResponseChecksumBytes() = Checksum(sResponseData)

dTemp = bResponseChecksumBytes(1) * 256

lResponseChecksumValue = bResponseChecksumBytes(0) + dTemp

If lResponseChecksumValue <> cReverseChecksum Then

sCommunicationsFault = "Bad Checksum"

bCommunicationsOK = False

End If

Endif

Note : The reverse checksum (cReverseChecksum above) should always be equal to &HF47

(0xF47).





16

6.6 Serial Link Protocol

The protocol ensures that communications between the PC (or other form of controller) and

the laser system is carried out in a way that ensures that spurious system operation cannot

occur due to communication error.

width setting.

2. Segment Duration (s) =

3. Parameter Set Width (s) / Accumulated Shape Segment Durations

4. The shape segment duration can be resolved down to 1us in line with the minimum

parameter set width. Its maximum value can represent 1 second in line with the

maximum parameter set width.

5. The maximum accumulated segment duration for a shape must not exceed 1 * 106.

Given the message resolution for segment duration, it takes several segments to

achieve this.

7.8.2 Read Laser Interlock Status (Control Code 0x74)

This command reads the status of the laser interlocks. It groups all of the interlocks together

rather than breaking them down into zones, so that they can be read using a single message.

Due to the cross monitoring of the interlock control, the status can be read from 2 devices

within the control system. The status from both of these devices should mirror each other. The

response data from this command returns the status information from both devices.

Transmit Data:

7.10 Command Block 8 (Laser Interface

Configuration Messages)


7.10.1 Set Interface Configuration (Control Code 0x92)

This command is used to set the specified interface configuration.

Note on Watchdog setting - This part of the configuration is used to enable and set the

allowable duration between communication messages. The watchdog is active when the laser

is in the standby or on state, so disconnecting communications when the laser is off will not

generate a watchdog failure. The watchdog is active for the interface(s) that put the laser in

the standby or on state. In this way an interface being used to monitor the laser can be

disconnected without causing the watchdog to fail.

7.11.2 Read Warning Value (Control Code 0xA5) - Changed message content

This message is used to retrieve any active warning conditions present on the laser. It is a

variable length message used to report all of the active warnings in one message. The

number of active warnings is included in the response. If this is zero, there are no active

warnings, and no further data is present in the message. Some warnings are fleeting, and

marked for clearing once they have been read. An individual warning list is maintained for

each interface, therefore some warnings may be reported that have previously occurred and

are no longer present when logging onto an interface for the first time.

Warning number allocations are listed in section Y.

A flag is returned to indicate the success or otherwise of the command.
