Patton 2089

Patton 2089 Interface Converter

Interface Powered, RS-232 (EIA-574) to RS-485
Patton 2089 Interface Converter (with Handshaking)

2089F RJ11 RS232/RS485 CONVERTER,DB9F/RJ11
2089F RJ45 RS232/RS485 CONVERTER,DB9F/RJ45

Connect RS-485 Data Acquisition & Control Equipment to a DB-9 (RS-232) Equipped PC or Workstation using the Patton 2089

Fully Conforms to the EIA RS-485 Standard
Data Rates to 115,200 bps
Range Up to 9 Miles (14.5 Km)
No AC Power or Batteries Required
Up to 50 Terminal Drops in a Multipoint Polling Environment
600 Watts of Silicon Avalanche Diode Surge Protection – Standard
The Patton 2089 is Patton’s first high speed EIA-574 (RS-232 on a DB-9) to RS-485 interface converter. Supporting async data rates to 115.2 kbps over one or two unconditioned twisted pair, the Patton 2089 passes one control signal in each direction. The Patton 2089 can handle up to 50 terminal drops in a multipoint polling environment; yet it is small enough to plug directly into a DB-9 serial port and requires no AC power or batteries for operation. The Patton 2089 has five configuration parameters, allowing the unit to be fine tuned to a variety of point-to-point or multipoint applications. Silicon Avalanche Diode surge protection is standard as well. Amazing!
