The RS-232 connector is DB9 female; the RS-485 connector is RJ-11; other connectors are available (see Related Items).
Built-in silicon avalanche diode surge protection against data loss and equipment damage from transient surges.
You can also "fine tune" impedance and "echo" characteristics for your individual application.
For configuration, the converter features two internal 4-position DIP switches.
Transmit data up to 115 kbps or at distances up to 4000 ft.
Operates in point to point or multipoint applications.
Operates 2-wire half-duplex or 4-wire half- or full-duplex.
Async (data leads) only.
Up to 32 RS485 devices can be attached to create a large multi-drop network.
The RS485 driver is automatically enabled during each spacing state on the RS232 side.
