UDS Motorola 202T
Frequency Shift Keyed (FSK) modem
  • The Motorola UDS 202T modem features built-in diagnostic and anti-streaming capabilities. The anti-streaming capability prevents a modem from remaining in the transmit mode when the modem is not actively transmitting data. The diagnostic features allow the user to verify transmitted and received data. The specific features are:
     

  • 2-wire half duplex or 4-wire full duplex private lineoperation

  • 0 to1200 bps data rate over unconditioned lines and 1,800 over high quality lines

  • Anti Streaming

  • Phase coherent, frequency shift keyed (FSK) modulation

  • LED indicators

  • Front panel rotary switch function selector

  • Integral test features

    The Universal Data Systems 202T is a Frequency Shift Keyed (FSK) modem which is designed for asynchronous operation at 0 to 1800 bps with C2 line conditioning, or 0 to 1200 bps asynchronous operation on unconditioned lines. The modem provides half duplex communications on 2 wire private lines or full duplex communications on 4 wire private lines, and is ideal for use in multipoint networks.

    The 202T is a single printed circuit card enclosed in a new compact size housing. The unit features an integral anti-streaming protection option which prevents network Tie-ups by incorporating a delay timer that will disconnect a modem, if it remains in transmit mode longer than a selectable period of time. The 202T also features strap options for Request to-Send/Clear to Send Delay timing, Transmit Carrier, local Copy Squelch, Turnaround squelch, Soft Carrier Turn Off, Carrier Detect Level, Carrier Detect Delay, and Test Generator Baud Rate Select. These strap options allow the user greater control of the modem, for his individual application.

    The 202T standalone modem is designed to be interchangeable between the Universal Data Shelf multiple modem enclosure and the stand alone modem enclosure. By removing the modem card and attaching the optional front panel, the modem can be directly inserted into the Universal Data Shelf. With this feature, a data-communications facility can be easily upgrade front multiple standalone enclosures to a centralized rack without the expense and trouble of purchasing new modems.

    Additionally a single 202T may be mounted in a standard 19" equipment rack via the UDS models RM16M Model 1 through model 29.
