RS232 Universal Serial T-Switch

  • RS232 Universal Serial T-Switch

Connecting three serial terminal devices

The Universal Serial T-Switch enables practically any imaginable uni- or bi-directional connection of three serial terminal devices. The T-switch has three serial terminals, each of which can be freely configured.

Properties

Interfaces:

  • 3 x RS232, 9-pin SUB-D connector
    • 1x DTE pinout
    • 2x DCE pinout

Management and Connectivity:

  • Operating modes:
    • Changeover using control sequences:
      • 1 computer runs for example two serial devices
    • time-controlled switching with adjustable switch time:
      • 2 computers share for example one serial terminal device:
      • Printer, plotter, hand scanner, card reader, etc...
  • No manual intervention necessary
  • Data back channel allows connection of bi-directional peripheral devices
  • Individual configuration of interfaces
  • Conversion of baud rate, data format and handshake protocol possible
  • Integrated diagnostic and startup aid: Setting dump

Power supply:

  • External
    • Wide voltage range up to 24V

Standards & more

  • Conforms to standards both in office and industrial environments:
    • High noise resistance for industrial environments
    • Low noise emission for residential and business areas
  • 5 year guarantee

Worth knowing

Notes on use:

The W&T RS232 Universal Serial T-Switch is an extremely versatile device. Virtually any uni- or bi-directional 2:1 coupling of RS232 devices is possible with this switch.

The Adapter has 3 serial ports: 1 Master port "C" and 2 Slave ports "A" and "B". Each of these ports can be parameterised independently of the others.

The Switch supports 4 data channels (Master C <> Slave A, Master C <> B), which are equipped in each direction with 1 MB buffers. The channels are switched either timed or using control sequences from one of the three Switch ports.
