Setup
Overview
The high-power Halogen Light Source with attenuator and shutter uses a 20-watt bulb for applications
requiring large-diameter optical fibers, or fiber and probe bundles. The attenuator and shutter can be
controlled by a series of ASCII commands issued by a host computer via RS-232.

Chapter 2
Operation
Optimizing the Optical Power Output
The HL-2000-HP-232 is adjusted at the factory to provide maximum power into a 200µm fiber. If a lower
optical power is required or a different fiber (bundle) diameter is used, you can adjust the optical power of
the unit.
►Procedure
Follow the steps below to adjust the optical power of the HL-2000-HP-232 Light Source:
1. Connect a fiber optic spectrometer or an optical power meter to a fiber, and then connect the other
end of the fiber to the HL-2000-HP-232’s SMA plug.
2. Loosen the blocking screw with the provided 1.3mm Allen wrench.

2: Operation
6000-10000-140-02-1209
3. Shift the SMA socket to optimize the optical power of the light source.
4. Tighten the blocking screw to secure the SMA socket position.

Appendix A
ASCII Commands
In serial communications mode, the motion controller is controlled via a series of ASCII instructions
issued by a host computer.
Motion-Related Commands
Command Function Description Example
M Initiate Motion Receipt of the "M" Move command initiates
motion using the values presently loaded to
determine the profile characteristics.
M
LA Load Absolute Position Allows programming of the desired target
position relative to the present zero or "home"
position.
LA 10000
LR Load Relative Position Allows programming of the desired target
position relative to the present position.
LR 10000
SP Load Command
Velocity
This parameter should be loaded with the
desired maximum profile velocity in position
mode. This value should be selected to not
exceed the capabilities of the mechanical
system. Additionally, this command sets the
maximum velocity value in "velocity mode".
SP 3000
AC Load Command
Acceleration
This parameter determines the acceleration and
deceleration rate to be calculated by the profiler
during execution. Argument in rpm/s2
(Allowed value: 0 to 20000)
AC 100
V Select Velocity Mode Execution of this command causes the
controller to switch into the Velocity control
mode. The motor will ramp the selected velocity
at the rate defined by the AC parameter.
V 2200
HO Define Home-Position Define present position as zero HO

A: ASCII Commands
10 000-10000-140-02-1209
Command Function Description Example
DI Disable Drive Execution of this command disables the drive
electronics and removes all current from the
motor
DI
EN Enable Drive This instruction enables the drive electronics
and allows the servo controller to become
active, providing motor current as required.
EN
LL Load Position Range
Limits
The range limit mechanism provides an
additional layer of protection. Both positive and
negative range limits are determined
independently using the sign of the limit
parameter. If the controller receives an
instruction from the host to move to a position
that is not within the range limit window, it will
stop at the set limit position.
LL 2000000
or
LL -5000000
Configuration-Related Commands
Command Function Description Example
POR Set Proportional Loop
Gain
The proportional gain determines the system's
proportional response to a given amount of
positional error. Increasing this parameter
provides a tighter and more dynamically
responsive system. (Allowed value 0 – 255)
POR 20
I Set Integral Loop Gain Unlike the proportional gain, where the
response remains constant if there is no
change in error, the integral term continues to
increase the effects of its response until it
becomes effective. This parameter determines
the rate of change of this response.
(Allowed value 0 – 255)
I 10
LPC Load Peak Current
Limit
This command sets the Peak current limit. The
LPC argument is in milliamperes.
LPC 1000
LCC Load Continuous
Current Limit
This command sets the continuous current limit.
The LCC argument is in milliamperes.
LCC 500
RN Reset Node This command resets the gains and current
limits to the values stored in the controller ROM
(the defaults).
RN

A: ASCII Commands
000-10000-140-02-1209 11
Command Function Description Example
DCE Delayed Current Error This command sets the delay between current
limit condition and setting the Fault-Status
(Fault-Pin and Fault-Bit for the GFS-
Command). The DCE argument is in
milliseconds.
DCE 200
SOR Source For Velocity This command defines the source for the
velocity of the motor.
SOR 0 defines that commanded velocity will
come from a serial command message using
RS232.
SOR 1 defines that the velocity value will be
an analog input voltage of +/-10 VDC at the
analog input. SOR 2 defines that the velocity
value will be a PWM signal at the analog input.
Note that the SP value dictates the Maximum
Velocity reached for the Maximum PWM signal
(SOR2) and the Maximum Velocity for 10 V at
the analog input (SOR1).
SOR 1
EEPSAV Save To EEPROM This command saves the current parameters
and configurations to EEPROM. The saved
parameters are recalled during power up so
that the motor is configured for use
immediately. After saving all configuration
parameters, a serial message "EEPROM
writing done" will be sent from the controller.
EEPSAV
NP Notify Position This command tells the motion controller to
send a "p" message when a particular position
is reached. In the example above, when 10,000
is reached a "p" message will be sent from the
controller.
NP 10000
External Limit Switch Configuration Commands
Command Function Description Example
HA Arm the "HOME" input This command is used to arm the Home Arming
mode. It is used with the external limit or
reference switch to define the home position
(the Analog input serves as this digital input as
well).
HA 1

A: ASCII Commands
12 000-10000-140-02-1209
Command Function Description Example
HL Home Limit Action This command is used to set the action that
occurs when the limit switch is activated. If HL
is set to 0, the motor will continue to run after
switch activation but will send an "h" message
signifying home switch was triggered. If HL is
set to 1, the motor will stop immediately after
switch activation.
HL 1
HN Hard Notify If HN is set to 1, it configures the motion
controller to send a serial message "h" once the
external limit switch is triggered.
HN 1
HP Define External Switch
Polarity
This command defines the activation edge of
the external switch. If HP is 0 a falling edge at
the external limit switch is valid. If HP is 1 a
rising edge occurs actions due to HL, HN and
HA-commands.
HP 0
HS External Switch Status This command returns the state of the limit
switch. If the limit switch was active and an HS
request is sent, the controller will return a 1. If
the limit switch was not active since a HL, HN
or HA-command was sent an HS request will
return a 0 to the host.
HS
