Operating Modes

The PLCS-21 can be operated in two different ways: as a controller for a compatible

PicoLAS diode driver and as a stand alone digital function generator. If used as a

controller it supports the voltage mode and the current mode, otherwise the frequency

generator mode. In either mode a number of trigger modes and thee different control

interfaces are supported. See section 6 for a detailed description of the trigger modes and

sections 7 and 8 for the control interfaces.

Using the LCS-21 as a Control Unit for a Laser Diode

Driver

First of all the PLCS-21 must be mounted on the laser diode driver by using the two

connectors on its bottom side and three screws M3 x 8 mm. PLCS-21 and the diode driver

are both powered by a single 15 V power supply via connector 1. Then a PLB-21 or a PC

with appropriate software must be connected to the PLCS-21. Now the PLCS-21 is ready

for use.

Important: Connector 3 must never be connected to any cable if the PLCS-21 is

mounted on a diode driver. Anything else can result in deformed laser pulses.

Though monitored by the PLCS-21 the power being fed into a laser diode may

exceed the adjusted value and can in some cases destroy your diode. Correct

operation is guaranteed only if connector 3 is left unconnected.

Furthermore, the connected diode driver must use its internal high voltage source.

See device specific datasheet for instructions how to enable the internal HV source.

Voltage Mode

This mode is active by default once a driver is connected to the PLCS-21. The pulse

width, repetition rate, voltage, temperature monitor and overcurrent detection of the

connected driver can be set. In Voltage Mode it is also possible to carry out a calibration.

See section “Calibration” for details. When it is done, a change to Current Mode can be

carried out.

Current Mode

When the calibration is successfully completed, a change to Current Mode can be carried

out. Now, in addition to the voltage, the current can alternatively be set. These two

parameters are linked together in such a way that a change to the set current always

generates a change to the voltage. The minimum value for the voltage is specified by U

min

;

the maximum value for the current is specified by I

max

. The interdependency of both

values is determined during calibration and is stored in the PLCS-21.

If another diode is connected to the driver or another driver is connected to the PLCS-21

the calibration must be manually repeated. A change of the diode or the driver (with the

same type) cannot be detected by the PLCS-21. If the values of U

min

or I

max

change, this

also means that a new calibration must be carried out in order to take the new limits into

account.

Using the LCS-21 as a Digital Function Generator

The PLCS-21 will automatically work in this mode if it is not connected to a laser diode

driver. Only the functions for setting the pulse width, repeat rate, trigger modes and

activating/ deactivating of the output are active. All others are not used and the

corresponding LSTAT and ERROR bits can be ignored. The generated signal can be

received from connector 3. The schematic of output circuit is shown in Figure 2. The

output amplifier will generate a square wave signal with an amplitude of 10 V. If a 50

Ohm load is attached to connector 3, this will result in a signal level of 5 V at the load.

Unlike the trigger inputs the output circuit is not galvanically isolated from the power

supply. To obtain a well formed signal a load of 50 Ohm is recommended. Refer to the

electrical characteristics on section “Electrical Characteristics” for further details.

Calibration

The PLCS-21 can calibrate itself to the characteristics of the connected laser diode. If the

calibration is successfully performed the user is able to switch into the current mode in

which either the precharge voltage or the diode current can be adjusted.

In order to perform a calibration a valid maximum diode current must be set. This value

will be the maximum current for the given diode. Note that a maximum of 99% of this

value will be reached during calibration in order to protect the diode. Furthermore a valid

minimum voltage (U

min

) must be supplied. Most times this will be slightly above the

threshold voltage of the connected diode. The user must assure that with this voltage the

minimum load current of the connected diode driver is reached. See device specific

datasheet for the actual minimum current. If the minimum load current is not reached

during the start of calibration, an error message is displayed and the user needs to increase

U

min

.

During the calibration the PLCS-21 generates a linear list of measuring points from which

it analyzes the relation of a given voltage to the measured current. If successfully

performed it saves the collected data, which is used to calculate a precharge voltage for a

given current. Now the user can not only set a precharge voltage, but also a set point

current.

Note that a calibration is only valid for a given hardware setting. The PLCS-21 cannot

detect any change in the connected laser diode. So the user must recalibrate it every time

the connected hardware is changed.

Trigger Modes

The PLCS-21 supports a number of trigger modes which are described below. The width

and repetition rate of the pulses generated are user defined. Pulses will always be

generated as long as the trigger condition matches and the laser is enabled.

As an input for the trigger signal the connector 4 or 5 can be used. Figure 3 shows the

schematic of both inputs. Note that they are galvanically isolated from the supply voltage.

For trigger levels see the electrical characteristics on section “Electrical Characteristics”.

Important: Never use both trigger inputs at the same time. Correct operation is not

ensured if both inputs are connected to a source. Furthermore, a signal fed into one

input may result in a current flowing out of the other input. This might damage

your trigger source.

In the following the different trigger modes are described separately. For more details on

the trigger modes please also refer to the table in the section “Description of the LSTAT

Register” on page 25.

Edge

In this mode an external trigger source is required to generate pulses. The pulses can either

be generated on the rising (mode 1) or the falling edge (mode 0) of the supplied trigger.

On each edge which equates the given setting, a given number of pulses (“Shots”) will be

generated.

ulse

In this mode an external trigger source is required to generate pulses. The PLCS will

generate pulses during the positive (mode 5) or negative part (mode 4) of the trigger

source.

Internal

In this mode the external trigger source is ignored. The PLCS will generate an infinite

number of pulses by itself and is selected by either trigger mode 2 or 3.

Controlling the LCS-21 using a LB-21

To control the PLCS-21 with a PLB-21 it must be connected via the enclosed cable. The

PLB-21 will not work if both, the USB and the PLB-21, are connected the same time.

When the PLB-21 is connected the first time to a PLCS-21 you are asked to download a

new driver. This must be confirmed with “yes” for the PLB-21 to work properly.

Menu Structure

The following diagram shows the structure of the PLB-21 menu which affects the PLCS-

ulseparameter

In this menu point you can modify the pulse length, repetition rate, current and voltage of

the pulse. The minimum and maximum values for every entry depend on your hardware

configuration. The PLCS-21 automatically detects the connected laser diode driver and

sets the values according to it. See the device specific datasheet for detailed information.

Width

This value defines the pulse width in nanoseconds (ns). The minimum and maximum

values are defined by the connected driver and by the actual repetition rate. In order to

generate the absolute maximum width, the user may need to reduce the repetition rate.

Reprate

This value defines the repetition rate in Hertz (Hz). The actual minimum and maximum

values depend on the connected driver an on the given pulse width. In order to generate

the absolute maximum repetition rate the user may need to reduce the pulse width.

Current

The current is only used in current mode. After a successfully performed calibration, the

user can set up a current which flows through the connected diode during the pulse. Note

that the voltage changes according to the given current as the precharge voltage is

automatically modified to match the set point current.

Voltage

This value defines the precharge voltage of the connected driver. The actual current

depends on the connected driver and diode. The maximum voltage depends on the

connected driver. If the set point voltage generates a current flow greater than the

maximum current defined by Imax, the laser will be disabled and an error message is

displayed.

LCS Config

In this submenu you can change the operation mode of the PLCS-21, the maximum pulse

current and the minimum voltage for calibration. Furthermore you can execute a

calibration.

Mode

The available operation modes depend on your hardware configuration. If you use the

PLCS-21 as a stand alone device (without a connected laser diode driver) it can only be

used as a frequency generator (“Freq. gen”), otherwise “Voltage” and/or “Current” are

possible. Before you can select “Current” you must perform a calibration. See section

“Operation Modes” and “Calibration” for more information.

I

max

This value defines the maximum current output of the connected driver. If the given

settings generate a higher current, the laser diode is automatically disabled. This requires

no calibration. If a calibration is performed this value defines the maximum current for it.

When the PLCS-21 is used as a frequency generator I

max

has no effect.

U

min

This value defines the starting voltage for the calibration process. It must be above the

threshold voltage of the connected laser diode. Otherwise the calibration will fail. In the

modes “Voltage” or “Freq. gen” this setting has no effect.

Calibration

When selected a press on the “Enter” key will perform a calibration. See section

“Calibration” for a detailed description.

Trigger

The PLCS-21 supports a number of trigger modes. For a detailed description of each mode

see section “Trigger Modes”.

Mode

This selects the used trigger mode. The modes are equal for all operation modes and

connected drivers. Available are “edge”, “internal” and “pulse”.

Logic

This option is only used when the trigger mode is either “edge” or “pulse”. In “edge”

mode you can select if pulses should be generated on the rising or falling edge of the

supplied trigger. In “pulse” mode it selects weather pulses should be generated on

“positive” (high) or the “negative” (low) part of the trigger signal.

Shots

When using the edge mode, the number of generated pulses can be determined by the user.

The given number of pulses will always be generated, even if another trigger is received

during generation.

Temperature

The PicoLAS laser diode drivers are equipped with a temperature sensor. In this submenu

the minimum, maximum, current and shutdown temperatures can be read and modified.

All values are in °C.

Dev. Off

This shows the user defined shutdown temperature. If the diode driver reaches this

temperature during operation, the laser will be disabled and an error message is displayed.

It can be modified within the boundaries defined in the device specific datasheet.

Dev. Max

This is shows the maximum operating temperature of the connected diode driver. It also

defines the maximum value for the shutdown temperature.

Dev. Act

This displays the current temperature of the diode driver.

PLCS Act

This shows the current temperature of the PLCS-21. It should not exceed 80 °C.

LD Info/Config

This submenu holds some information and configuration options of the connected laser

diode driver.

Name

This shows the name of the connected laser diode driver.

Reset to def.

This forces the PLCS-21 to reset all parameters to factory defaults. All settings and

calibration data are lost.

Controlling the LCS-21 via USB

Introduction

In addition to being able to connect up a PLB-21, the PLCS-21 also has a USB interface to

communicate with a computer/laptop. This interface allows communications over both a

serial text interface as well as using the PicoLAS protocol. While the text interface is

designed for communication with a terminal program, the PicoLAS protocol is designed

as a system interact protocol.

The switching between the two protocols occurs automatically as soon as the PLCS-21

receives a certain sequence. The corresponding commands are:

•PING for the PicoLAS protocol

•“init” followed by <Enter> for the text interface

If the PLB-21 and the USB interface are both connected at the same time then only the

USB interface can be used. As soon as the USB connection is connected to a computer

then the PLCS switches automatically over to this.

Description of the USB Interface

The USB connection of the PLCS-21 emulates a virtual COM port under Windows. The

necessary drivers can be downloaded free of charge under

http://www.ftdichip.com/Drivers/VCP.htm or they are already included in the current

Linux kernels. The virtual COM port created by this can be addressed like a regular one.

The connection settings are:

Baud rate 115200

Data bits 8

Stop bits 1

Parity even

14

The Serial Text Interface

The following section describes the structure and commands of the text interface.

Structure

Every command that is sent to the PLCS-21 must be completed with a CR (Enter). It

consists of a command word followed by a parameter. If the command was successfully

executed then a “0” is sent, otherwise a “1”. If the command requires an answer

parameter, this parameter is sent before the confirmation is given.

Example:

The user would like to read out the voltage currently being used by the driver.

User input: gvoltage<Enter>

Output of the PLCS-21: 12000

0

Input is done in ASCII code and is case sensitive. Every terminal can be used that supports

this standard.

If an Error occurs

If an error occurs during operation the pulse output is switched off and a message is sent

to the terminal. Errors have to be acknowledged with “clrerror” otherwise switching on

again of pulse output is not possible. Note that warnings are also displayed this way but

these do not switch off pulse output. Hence it is not necessary to acknowledge warnings

with “clrerror”.

The icoLAS rotocol

The following section describes the structure and possible commands of the PicoLAS

protocol.

Structure

Each transmission consists of 12 bytes – called a frame as follows – which must be sent

consecutively. Otherwise the system times out and the transmission must start again from

the beginning.

A frame has a fixed structure. The first two bytes describe the command, the following

eight bytes the parameters, followed by one reserved byte and one checksum byte. The

checksum is calculated out of the first 11 bytes which are linked by a bitwise XOR.

Thus a frame has the following structure:

Byte Meaning

1 Bit 0-7 of the command

2 Bit 8-15 of the command

3 Bit 0-7 of the parameter

4 Bit 8-15 of the parameter

5 Bit 16-23 of the parameter

6 Bit 24-31 of the parameter

7 Bit 32-39 of the parameter

8 Bit 40-47 of the parameter

9 Bit 48-55 of the parameter

10 Bit 56-63 of the parameter

11 Reserved, always 0x00

12 Checksum

A properly received frame must be acknowledged by the recipient with an answer, which

is also a frame. If the acknowledgement does not occur then the command has not been

processed and the sending procedure should be repeated.

If the recipient recognizes the command as valid, but not the parameters, then it will

answer with an ILGLPARAM (0xFF12) as command.

In the case that the recipient receives an invalid command it will answer with UNCOM

(0xFF13).

If a faulty checksum is recognized then the answer is RXERROR (0xFF10). If this error

occurs often then the connection should be checked.

Using the REPEAT (0xFF11) command the recipient can instruct the sender to send the

most recent frame again.

General Commands

The following list contains an overview of the general commands which are supported by

every product from PicoLAS which makes use of this protocol. The explanation of the

individual commands is given further below.

PING

Is used to determine the presence of a connected recipient and to initialize the interface of

the recipient for this protocol. Has no effect on the condition of the recipient. The

command parameter is always 0, the answer parameter too.

It is used to determine the device ID of an attached recipient. Has no effect on the

condition of the recipient. The parameter is always 0. The answer contains the ID.

GETHARDVER

Instructs the recipient to send back the version number of the hardware being used. The

parameter is always 0. The answer contains the hardware version of the recipient. The

format of the answer is: 0x000000<major><minor><revision>. In other words: one byte

for each of the three elements of the version number.

As example, version 1.2.3 has the parameter 0x000000010203.

GETSOFTVER

Instructs the recipient to send back the version number of the software being used. The

parameter is always 0.

The answer contains the software version of the recipient. The format of the answer is:
