Model 2089
Interface Powered, RS-232 (EIA-574) to RS-485 Interface Converter (with Handshaking)
Connect RS-485 Data Acquisition & Control Equipment to a DB-9 (RS-232) Equipped PC or Workstation
|
- 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 Model 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 Model 2089 passes one control signal in each direction. The Model 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 Model 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!
Transmission Format: Asynchronous
Data Rate: Up to 115,200 bps
Range: Up to 9 miles (14.5km)
EIA-574 Interface: DB-9, male or female
RS-485 Interface Options: RJ-11 or RJ-45 jack, terminal block with strain relief
Transmit Line: 2, 4 wire unconditioned twisted pair
Transmit Mode: 4-wire, full or half duplex; 2-wire half duplex
Control Signals: DSR turns "ON" immediately after the terminal raises DTR; DCD turns "ON" after recognizing the receive signal from the line; CTS turns "ON" after the terminal raises RTS.
RTS/CTS Delay: 0 or 8 msec
Carrier: The carrier is switch selected either continuous operation or controlled by RTS
Surge Protection: 600W power dissipation at 1 mS
Power: Draws operating power from EIA-574 data and control signals; no AC power or batteries required.
Temperature: 32° to 122° F (0° to 50° C)
Size: 2.50" x 1.20" x 0.75" (6.4 x 3.0 x 1.9 cm)
