3 afety
The hardware described within this document is designed to control a laser scanner system. Laser radiation
may effect a person's health or may otherwise cause damage. Prior to installation and operation compliance
with all relevant safety regulations including additional hardware-controlled safety measures has to be
secured. The client shall solely be responsible to strictly comply with all applicable and relevant safety
regulations regarding installation and operation of the system at any time.
Beside of that some laser equipment can be damaged in case it is controlled with wrong signals or signals
outside a given speci<cation. Thus it is highly recommended to check the output generated by this hardware
using e.g. an oscilloscope to avoid problems caused by wrong con<gurations. This should be done prior to
putting a system into operation for the <rst time, whenever some parameters have been changed or whenever
any kind of software update was installed.
The hardware described here is shipped without any cover and without prefabricated equipment for electric
installation. It is intended to be integrated in machines or other equipment. It is not a device for use "as is", but a
component which is intended to be used as part of a larger device, e.g. for integration in a machine with own
housing or within an electrical cabinet. Prior to operation compliance with all relevant electric /
electromagnetic safety regulations including additional hardware-controlled safety measures has to be
secured. The client shall solely be responsible to strictly comply with all applicable and relevant regulations
regarding installation and operation of the system at any time.
The hardware described here is an electrostatic sensitive device. This means it can be damaged by common
static charges which build up on people, tools and other non-conductors or semiconductors. To avoid such a
damage, it has to be handled with care and including all relevant procedures (like proper grounding of people
handling the hardware, shielding/covering to not to let a person touch the hardware unwanted, proper
packaging in ESD-bags, ...). For more information please refer to related regulations and standards regarding
handling of ESD devices. The EMC Directive (201 /30/EU) does not apply to this hardware as it is not intended
for an end user (a person without knowledge of EMC) and as it is not otherwise made available on the market.
The Low Voltage Directive (201 /35/EU) does not apply to this hardware as the voltage supply is below the
50V AC / 75V DC limit.

or may be changed without further notice.

4 Overview
This document describes the HALdrive X20 converter board, its electrical characteristics and usage.
This board is designed to receive digital XY3-100 scanner controller signals and to convert them to 2x
synchronous analogue output signals. So it acts as some kind of converter between two different signal types
for controlling scanning systems/scanheads.
This board is not a ready-to-use device but a component which is intended to be integrated in larger devices or
to be operated with an own housing.
4.1 Features
The HALdrive converter board provides the following features:
•accepts 2D input signals in XY3-100 format (X and Y position data, Z is ignored if available)
•synchronous output of analogue X and Y position data in +-5V.. +-10V range (values in between are
available on request)
•20 bit output resolution
•100 kHz sampling/output frequency
•XY3-100 backchannel
•instant-on, so there is no boot-up time until the device is available
•input voltage range of +-15..+-2 V, wider voltage range available on request

5 HALdrive Board And Connectors
The board provides the following connectors:
1. XY3-100 interface for power supply and scanner input signals (as described below)
2. 2,5 mm 6pin connector for Galvo-X and Galvo Y analogue output signals
3. Optional separate power supply input pin, when not already provided via connector (1)
5.1 canner ignals
The (optionally white) 26 pin connector expects the XY3-100 position signals and the power supply for the
HALdrive board:

25 -V -15..2 V 26
When the HALdrive is used together with the E1803D scanner controller card, a direct 1:1 connection can be
established between the white, 26 pin scanner signal connector of the E1803D controller and this connector.
Then power has to be supplied via the three screw-connectors of the E1803D (for details please refer to
manual of E1803D scanner controller card).
For all other scanner controller cards, wring has to be done according to their pinout. For further information

please refer to appendices below.
5.2 Galvo X and Y ignals
A standard 6 pin 2,5 mm header, to be used with an IDC connector:
Pin ignal Description
1 NC Unused and reserved for future use, do not connect!
2 NC Unused and reserved for future use, do not connect!
3 Galvo-Y analogue output with voltage possible in range +-5V..+-10V
Galvo-X analogue output with voltage possible in range +-5V..+-10V
5 GND Common ground for Galvo-X
6 GND Common ground for Galvo-Y
Pins 3 and typically work in range -5V..+5V. For the +-10V hardware variant the Pins 3 and work in range -
10V..+10V. Pins 5 and 6 is connected to GND.
The maximum current to be pulled out of each of the outputs should never exceed 20 mA. Lower currents are
recommended to avoid unnecessary heating of the whole board.
5.3 Optional Power upply Input
These are optional separate power supply input pins which can be used when power is not or can not provided
via connector (1). Here a symmetric voltage in range +-15V..+-2 V can be fed in. The two outer pins marked
with “-” are for -15V..-2 V, the two middle pins are for GND and the two other outer pins marked with “+” are for
+15V..+2 V power input.
When no power supply with symmetric/bipolar outputs is available, it is possible to combine two standard
power supplies, here GND of the <rst power supply has to be connected with +V of the second power supply
and with the GND-pins of the HALdrive:

6 Initial Operation
After the HALdrive does not have a nameable boot-up time, putting it into operation consists of a few steps
only:
1. power up HALdrive and if necessary the connected scanner controller card
2. power-up connected galvo drivers (can be done together with powering the HALdrive)
3. start sending data from the scanner controller card to the HALdrive board
For security reasons it is recommended to not to send any data to the HALdrive while it is still turned off, so
that it may start up in the middle of an already running data transmission. This may lead to a situation where the
<rst valid position command received is at an extreme and unexpected position causing damage to the
connected scanhead as it jumps to this extreme position too fast.
For the same reason also the galvo driver should be powered and be ready to use before the scanner controller
sends any data, elsewhere when the connected galvos jump to an extreme position immediately, this may cause
damage to the galvos and/or mirrors.
