Model 62-1/2
RS-232 to EIA-530 Interface Converter

Conversion between RS-232 and EIA-530 is accomplished by the Model 62-1 and 62-2. This device provides conversion for the entire EIA-530 interface which includes ten Category I circuits and three Category II circuits. The 62-2 is designed to interface to a DCE RS-232 port. The electrical interface of the EIA-530 port fully complies with RS-422. The Category I signals are differential and the Category II signals are single ended. The unit therefore, fully complies with the signal requirements of MIL-STD-188-114, Type 2.

  • Supports 10 Category I & 3 Category II Circuits
  • Full EIA-530 & RS-422 Compliance
  • DTE & DCE Models
  • Meets MIL-STD-188-114 Type 1/2
  • Up to 256 KBPS Data Rate
