MR-0133, 2x RS-485TXN 101 33

MR-0133, 2x RS485, with its own power supply, galvanic isolation

The MR-0133 submodule contains 2x RS-485 interfaces.
The internal connection ensures galvanic separation of the interface from the system and power supply circuits.
In the variant with the number TXN 101 33.01, both buses have already connected a 120 Ω terminating resistor.
At the same time, the module contains identification circuits. The user has the opportunity to identify the type of submodule used from the development environment.

Attention! Because the module contains semiconductor components, it is necessary to follow the principles for working with electrostatic sensitive components when handling the removed cover. It is not allowed to touch the printed circuit boards directly without protective measures.
Description Terminal communication interfaces are typically equipped with connectors. The connection of the connectors is specified in the documentation of the respective system where the submodule is used.
Module operation
Module configuration Submodules with an RS-485 interface contain solder jumpers, which are used to connect a terminating resistor network. They are marked "BT1" for the first channel and "BT2" for the second channel. By default, submodules are shipped with jumpers disconnected.
Generally Warranty and complaint conditions are governed by the Terms and Conditions of Teco a.s.
Warning All conditions of this documentation must be met before turning on the system. The system must not be put into service unless it has been verified and confirmed that the machinery of which the Foxtrot system is a part complies with the requirements of Directive 89/392 / EEC, in so far as it applies to them. Documentation subject to change.

  • CP-2000 and DMX - You can use standard submodules MR-0131 and MR-0133 but you have to download version 1.3 of DMX512Lib and update a firmware in CPU to 3.3 and in MR-013x sub-module to 1.7 versions. Then DMX512Lib will be supported in CP-20xx too.
