ASYNC RS-232 TO 2-WIRE RS-485 CONVERTER
2. Introduction
2.1 Description
The Async RS-232 to 2-Wire RS-485 Converter provides
excellent versatility in a compact package. Requiring
no AC power or batteries for operation, the Converter
supports asynchronous RS-232 data rates to 115.2 kbps
over one unconditioned twisted pair in half-duplex
mode. The line is automatically turned around from
receiving to transmitting upon the beginning of
receiving of RS-232 data. No RS-232 control signal is
needed to turn around the line.
The Converter is equipped with either male or female
DB25 connectors for RS-232. For the twisted pair
connection, you can choose either a 4-wire terminal
block or an RJ-45 female connector. Silicon Avalanche
Diodes provide 600 watts per wire of protection against
harmful data-line transient surges.
