  Features & Benefits
  • Auto-Directional Data Conversion
  • Automatic Parallel-to-Serial or Serial-to-Parallel Mode Selection
  • Automatic DCE/DTE Mode Selection (Model 2025 only)
  • Support for Both Hardware and X-On/X-Off Flow Control
  • Data Rates to 38,400 bps
  • External Configuration Switches
  • No AC Power or Batteries Required
  • Integral 6 foot (1.8m) Cable (Custom Connectors and Lengths Available)
  • Link Status LED Indicator

The Patton Model 2025 & 2029 miniature serial to parallel converters represent a breakthrough in size and performance. The Model 2025 & 2029 support auto-directional data conversion, serial data rates to 38.4 kbps, plus both hardware and X-On/X-Off handshaking. Yet they are no larger than a DB-9 or DB-25 backshell (excluding cable), and require no AC power or batteries for operation!

The Model 2025 is designed to plug directly into an RS-232 device with a DB-25 serial port. The Model 2029 plugs directly into an EIA-574 (RS-232) device with a DB-9 serial port. Both come equipped with a six foot cable. And both models use microprocessor technology to automatically orient themselves for serial-to-parallel or parallel-to-serial data conversion. A single LED indicator monitors five modes, including transmit status.
