Professional Grade RS-485 Converters

Integrity Instruments designs and manufactures the world’s most advanced RS485 converters available. All Integrity Instruments RS232 to RS485 protocol converters are microprocessor controlled to provide fully automatic half-duplex RS485 send data control. We have developed advanced algorithms that automatically adjusts to communications baud rates and provide automatic RS-485 transmit enable control, while providing fully software configurable overrides for situations that demand precise timing control. All Integrity Instruments Professional / Industrial grade eXtra Performance (XP) RS485 converters are rated for industrial temperature range (-40C to +85C).

RS485 converter features:
• Microprocessor controlled
• Fully automatic and auto speed sensing (no DIP switches)
• LED indicators for: power, TX data, and RX data
• DCE/DTE configurable on all models
• DB9, DB25 and DIN rail mounted options
• Jumper selectable RS485 termination
• Echo control (on/off)
• RoHS option
