Overview
The LINDY RS232 <> 422/485 interface converter is an optically isolated
bi-directional converter. It converts full or half-duplex serial RS232C
signals to optically isolated, balanced, full or half duplex RS422 or RS485
signals at baud rates up to 115.2 kbps. It suppresses surges from the
RS422/485 lines. It has built-in photoelectric isolators for high voltage
(3500VRMS 500VDC) protection. A rapid transient voltage suppressor
circuit can protect up to a certain level of lightning (600W) and 15kV
ESD.
It features send data control circuitry so no software control of handshake
lines is required in RS485 mode. It provides Point-to-Point, Multi-Drop
(up to 32 devices) and Simplex Operation and can be powered from a
DC 9V to 12V > 200mA power adapter.
A single slide switch is used to configure to either RS422 or RS485
mode. Support for both half duplex and full duplex, latter only for 4 wire
transmissions. RS422/485 connection cable can be attached either by an
RJ11 cable or via the screw terminal block.
Another slide switch configures the unit for either DTE or DCE mode.
Features
• RS232 interface for connection to a DTE or DCE device
• Compliant to EIA / RS232C/422/485 Standards
• Optically isolated with surge, lightning and ESD protection
• Supports half and full duplex RS422/485
• Automatic half/full duplex and handshake recognition and setting
• Typical distances and max. data rates supported using AWG 24 wire:
