1 Device Overview
LTR-1200
Features
Description:
The LDD/ TEC 19" rackenclosure LTR-1200
is a highly configurable, ready-made carrier
system facilitating the integration of up to 4
devices belonging to either the LDD-Family
of laser diode drivers or the TEC-Family of
Peltier/TEC controllers. The system caters
for power, cooling and communication.The
combination of built-in devices (models,
number) is freely selectable by the customer,
their application will dictate the choice (12V
or 24V) and number of internal primary DC
power supplies. Meerstetter Engineering will
take care of the integration and provide a
fully configured turnkey solution.
Up to 4 fans drag air sidewise through the
rack enclosure. Their speed is managed by
intelligent fan control on a dedicated PCB
such that air-cooling becomes effective upon
prolonged use at high ratings. For table-top
operation, the rack mounting brackets can be
removed.
The status of the rack enclosure and of the
built-in devices are indicated on thefront side
display (2x40 characters) and by dual color
LEDs. The most important settings (parame-
ters of the built-in devices and of the front
side data interfaces) can be adjusted over
the 5-way navigation switch.
For advanced operation and configuration,
all internal devices can be addressed over
one of the interfaces; therefore, the originally
supplied TEC and/or LDD Service Software’s
can be used. For continuous monitoring and
control by customers' systems, the serial
communication protocol 'MeCom' can be
used: on one hand, it allows direct control of
the each built-in LDD and TEC device, on the
other hand it allows polling further infor-
mation about the overall system status.For
fast signals (such as LDD pulse triggering)
three digital input lines are available. Also,
one digital output is available (e.g. for error
indication).The integration of third-party
hardware (such as fiber-coupled diode la-
sers) is possible if dimensional requirements
are met.

3.4 Communication Interfaces
3.4.1 LTR-1200 Communication Concept
The LTR-1200 is equipped with several communication interfaces, which can be used simul-
taneously.
Every communication interface has its own receiving buffer.
The router will process every received message. The message is forwarded to the desired
device. As soon as the router task has received the responding message from the device, the
message is forwarded to the corresponding interface.
Every communication interface has the same priority. All messages are processed succes-
sively.
A connection is always between one control software and one device. The Terminal, device
number and Channel are not directly associated.
Terminal represents only the output on the backplane of the LTR-1200. One device can be
connected to more than one Terminal.
Channel represents the output channel of one device (e.g., CH1 or CH2 in the case of TEC
controllers.)
Please consult the “LTR-1200 Configuration Sheet” (which was supplied with the LTR-1200)
to find out which device channel is connected to which Terminal.
3.4.2 Maximum Cable Length for RS232, RS485 and I/O
For proper functioning, the maximum cable length for RS232, RS485 and I/O connections is
3.00 m.

3.4.3 Connecting LTR-1200 over Ethernet
The LTR-1200 does not support DHCP. A fixed IP Address configuration must be set over the
display menu. Please set the following settings:
•IP Address
•Gateway Address (required for routing)
•Network Mask
Please try to access to the built-in LTR-1200 web server by entering the previously configured
IP Address to your web browser.
3.4.3.1 Ethernet Connection
Please refer to 3.1 Device-specific Documentation to connect the Service Software over Ether-
net. The Device Address (Device to be addressed) can be found on the LTR-1200 Menu or on
the Built-in web site. It usually is the same as the Terminal Number. The LTR-1200 provides a
total of six connections (TCP/IP, Port 50000, Timeout: 10s) to control the LDD/TEC Drivers
over Ethernet. For Third Party Software communication please refer to the MeCom communi-
cation protocol specifications (See chapter 3.1 Device-specific Documentation).
3.4.4 Service Software Default Address
In some cases, it may be helpful to configure a default LDD/TED driver as standard device.
This can be done by setting the 'Service Software Default Device' parameter to a specific
LDD/TEC Device Address in the Displaymenu. In this case the Device Address 0 will berouted
to the 'Service Software Default Device'.
3.4.5 Access over Third-Party Software
For Third Party Software communication please refer to the MeCom communication protocol
specifications (See chapter 3.1 Device-specific Documentation).
3.4.6 Communication Fault Management
3.4.6.1 For RS485, RS232 and USB Interfaces
A received MeCom-Package with a wrong CRC is not being processed, no error is generated.
If a MeCom-Package is being forwarded to a device (LDD/TEC) and no answer is received
from the device, no error is generated. The sending host must repeat the MeCom-Package.
3.4.6.2 For Ethernet Interface
A received MeCom-Package with a wrong CRC results in closing the corresponding TCP con-
nection. If a MeCom-Package is being forwarded to a device (LDD/TEC) and no answer is
received from the device, the MeCom-Package is being sent to the device two more times. If
still no answer is received, the TCP connection is closed by the LTR-1200.

4 Technical Data
4.1 Elements and Configurations
Each rack enclosure is equipped and configured to the customer's specifications:
•Up to four LDD-Family orTEC-Family devices can be built in (See 5 Quotation Request
Form).
•The number of required power supplies and fans depends on types, numbers, and
applications of the built-in devices. Meerstetter Engineering equips the LTR-1200 ac-
cordingly.
•The LTR-1200 is back panel configurable, the standard panel offers 4 power output
terminals and 4 sensors inputs connectors. (Up to 8 Terminals are possible)
•It is also possible to install third party devices. Please contact Meerstetter Engineering
with your enquiry.
•Important note concerning the integration of LDD-Family devices into LTR-1200 rack
enclosures: The internal wiring from an LDD device to its back panel terminal can
measure several 10cm and represents an inductive load. Therefore, fast pulsing per-
formance will be impaired.

4.3 Back Panel
Picture of 4 Terminal Version. (Only approx., the sensor connectors are wrong)
Picture of the 8 Terminal Version
By standard, the GND potentials of all built-in TEC and LDD devices are interconnected. Con-
sequently, all external loads and sensors to be attached to the back panel should be potential-
free. At the most, only one single potential (e.g. GND of one laser diode) may be tied to a given
potential; it is however recommended to keep all loads and sensors potential-free.
Upon customer request, individual outputs can be equipped such that they are potential-free
(i.e. independent of other built-in devices). Please contact Meerstetter Engineering with your
