RS232 Intelligent T-Switch

  • RS232 intelligent T-switch

Multiplexing of an RS232 interface

Properties

General information:

  • Bi-directional switch with 128 kByte-memory
  • Baud rates and protocol conversion
  • Individual configuration of interfaces
  • Programmable control sequences and code conversions
  • Integrated diagnostics and start-up aids, such as
    Configuration dump, handshake test

Background information:

The W&T RS232 intelligent T-switch is and extremely versatile device. Nearly all uni-directional and bi-directional 2:1 couplings of RS232 devices can be implemented with this switch. The adapter is equipped with 3 interfaces that are freely and individually configurable: 1 master interface and 2 slave interfaces that are able to communicate with each other. The switch has 4 data channels (master <> slave A, master <> slave B) with a 32-kByte buffer in each direction and can be equipped with programmable code conversions. The switching between channels is time-controlled or by means of programmable control sequences at the master interface.
