Why Let Ground Loops Disrupt Your RS-232 Communications?

The Patton Model 590 Series of RS-232 to RS-232 optical isolators guards your asynchronous equipment from the hazards of ground looping. Plugging directly into your DTE hardware, the Model 590 Series provides 2500V RMS peak DCE/DTE isolation. Both the Model 590A (19.2 kbps max) and Model 591A (115.2kbps max) isolate 4 lines on the RS-232 interface--two of which are selectable by internal jumpers. The Model 592 (19.2 kbps max) and Model 594 (115.2kbps max) isolate 7 pre-wired lines on the RS-232 interface.

  • Four New Models to Choose From
  • No External Power Required (590A, 591A)
  • 2500V RMS Peak Isolation
  • Models 590A and 592 Support Async Data Rates to 19.2kbps
  • Models 591A and 594 Support Async Data Rates to 115.2kbps
  • Extends RS-232 Distances (when AC Powered)
  • Models 590A and 591A Isolate 4 Lines: TD&RD plus DTR or RTS (strap selectable) and CD, DSR or CTS (strap selectable)
  • Models 592 and 594 Isolate 7 Lines: TD, RD, RTS, CTS, DSR, CD and DTR
