- Operates at speeds up to 115.2 kbps.
- Transmits up to 4000 feet (1219.2 m).
- Use point-to-point or multipoint.
<b>Further Details</b>
- Operates in half- or full-duplex over two or four wires.
- Works with or without transmit "echo."
- The converter's RS-232 side has a DB25 female connector configured as DCE.
- The converter's RS-485 side has a DB25 male connector.
- Also available in four other configurations. See Similar Products.
The IC1478A-F is like the IC1476A-F-US, except that it’s for 2-wire operation and its RS-485 connector is a DB25 male instead of a terminal block.
Our Async RS-232 to RS-485 Interface Bidirectional Converter, DB25 Female to DB25 Male converts unbalanced, full-duplex RS-232 signals to balanced half-duplex RS-485 signals. It uses two user-selectable methods to enable the RS-485 driver, either by toggling Request to Send (Pin 4) of the RS-232 side or by sensing the data on the Transmit Data (Pin 2) of the RS-232 side automatically. By removing both sets of jumpers, you can constantly enable the RS-485 driver and receiver. In other words, it can act like an RS-422 converter.
