LTR00 Dummy module

Dummy module
  • There is a constructive possibility to fix the user-designed sub-module board at the second tier
  • On the entire free area of the LTR00 board there are empty seats for output elements and SMD seats
  • Available versions: with a DRB-37M connector for user connections and with a blank panel without connector
  • LTR00 module is designed for mounting user nodes (the ability is provided by user)
  • The node of the stabilized power supply +5 V (0,2 A), +/- 15 V (2x0,04A) (both outputs with individual galvanic isolation)
  • There is no software access to LTR00 module
Power source for LTR00
Output voltages and currents of two galvanically isolated power supply sections 1) ±15 V, 2x40 mA
2) +5 V, 200 mA
Protection against short-circuit of power supply outputs Thermal, by overheating of stabilizers
Power source conversion frequency 400 kHz
Galvanic isolation voltage relative to the crate case 500 V
Design parameters
Permissible dimensions of printed circuit board of a submodule installed by user 100 x 94 mm (preliminary data!)
Connector type at the panel LTR00-01 DRB-37М connector
LTR00-02 connector is missing
The basic step of holes on LTR00 board 1,27/2,54 mm


Details of the application of LTR00 and restrictions on the use can be found in the Manual.

  • lcomp.exe (filesize: 6 342 216 bytes, date: 12.05.2021)

    Beta version. LCOMP library for Windows XP/Vista/Win7/Win8/Win10 32 and 64-bit versions with drivers. The installer and drivers are digitally signed. The library is built on the basis of modern WDM-drivers rewritten on WDF. It includes the WDM driver itself for L-CARD hardware, the DLL library with source code, programming examples, electronic description, etc. The LCOMP library provides support for almost the entire range of products: PCI boards, USB modules. ISA support is excluded.

    The library includes “L-Graph I” software. L-Graph I supports the following devices: L-1450, L-761, L-780, L-783, L-791, E14-140, E-154 and E14-440. Files recorded by L-Graph I can also be read and processed using the demo-version of PowerGraph v.3.X.

  • ltrd-setup.exe (filesize: 1 467 408 bytes, date: 19.08.2021)

    The ltrd service. Version Provides communication with LTR crates. It is a replacement for the LTRserver software while maintaining the compatibility of the program interface. ltrd is designed for the same purpose as LTRserver, but it is a service that runs when the system is started. The graphical interface to the service is provided by a separate LTR Manager program.

    Attention! Only one of the programs ltrd or LTRserver can work at a time.

  • ltrdll.exe (filesize: 1 328 600 bytes, date: 30.11.2021)

    Libraries for working with LTR crates and modules. Version 1.32.30.

  • ltrmanager_setup.exe (filesize: 9 751 808 bytes, date: 04.05.2021)

    LTR Manager software. Version 1.5.2. Graphical interface to the ltrd service. Provides an interface similar to the LTRserver interface when working through the ltrd service.
