Several Possibilities for the Remote Control of TEC Controllers

TEC controllers are used for thermoelectric cooling and heating in combination with Peltier elements or resistive heaters. Peltier elements are heat pumps which transfer heat from one side to the other, depending on the direction of the electrical current. TEC controllers are used to drive the Peltier elements.
There are several different ways to communicate with TEC controllers, which we present here.

TEC Controller Product Overview

Stand-Alone Operation

TEC Controllers can operate autonomously without external control like a PC. The following examples show the possible modes of stand-alone operation:

  • Temperature controller: hold an object at a given temperature
  • Lookup table / scripting: generate a predefined temperature profile
  • Power supply with constant current and voltage

TEC Remote Control Modes

Remote control modes for TEC controllers

Serial Communication

Serial communication is used to send data from a host to a TEC controller and receive data from the controller, respectively. The following physical interfaces are supported:

  • RS232 (TTL)
  • RS485
  • USB

Ethernet Communication

Communication over Ethernet is possible by integrating up to four TEC controllers into a LTR-1200 19‑inch rack enclosure, which offers an Ethernet connector. This allows the integration into a standard 19‑inch rack or it can be used as table-top instrument.

Service Software

The TEC Service Software is a user-friendly interface for the implementation, testing and maintenance of the TEC controllers. The service software can be connected via the above mentioned interfaces.

MeCom Communication Protocol

MeCom is the open serial communication protocol for TEC controllers, upon which all communication is based. It is possible to fully control a TEC controller over the MeCom Communication Protocol. The TEC Service Software does not necessarily be running. More information in the download section.

MeCom API

  • MeComAPI: TEC Controller Communication Protocol implementation for C and C++ applications (C‑code implementation of MeCom Protocol Spec 5117 and TEC Controller Communication Protocol 5136)
  • MeComAPI for .NET: TEC Controller Communication Protocol implementation for C# applications. The precompiled DLLs can also be used for a Visual Basic project.

More information in the download section.

LabVIEW

For LabVIEW users we provide an example VI that has the basic functionality of a control software for the TEC controllers. The following functions are implemented:

  • Communication with TEC controller
  • Monitoring of operation parameters
  • Error handling
  • Charting for the object temperature

Digital I/O (Platform Bus Connector) RES1 … RES8 Control Signals

Along with the data interface for RS485 and RS232 (TTL), the platform bus offers several other remote control functions on the hardware pins:

  • Status
  • Triggering
  • Enable

More information can be found in chapter 6.2 of the TEC Controllers User Manual.
