Fully Isolated RS-232 to RS-422/RS-485 Converter

Fully Isolated RS-232 to RS-422/RS-485 Converter
The MODEL485P is a high performance RS-232 to RS-485/422 interface converter. The product features optical-electrical isolation rated to more than 2.5KV and internal power isolation. It has surge protection on its data lines. The powerful line drivers allow for long distances of RS-422/485 serial transmission. The converter offers high data transfer rates and reliable performance. It automatically adjusts to the data rate and features automatic flow control for RS-485.

The converter has broad application in industry control systems. Power can provided from the RS-232 handshake lines or the included 9 VDC plug pack.

The converter has a male DB-9 port on the RS-232 side. The RS-485/RS-422 side has a female DB-9 connector and an RJ45 jack. The RS-485 and RS-422 signals are brought out to pins on both connectors. The box includes a DB-9 to screw terminal adapter which breaks out the RS-485 and RS-422 signals.

Features:

  • Isolated power supply, 2500 V signal isolation, 1500 W surge protection
  • Transmission distance can reach up to 1800 m at the rate of 115.2 kbps on RS-422/RS-485
  • Interface auto-adaptive technology: no DIP switches or jumpers to set
  • Automatic data flow control for conversion of the full duplex RS-232 to the half duplex RS-485
  • Automatic signal rate sensing, zero delay automatic transmit
  • Includes 1 meter DB-9 Male To DB-9 female cable
  • Includes 9 VDC Plug Pack
  • Includes female DB-9 to screw terminal adapter
