CV3285M - Конвертор RS232/RS485|
The easiest and cheapest way to connect
different measuring devices in a network is the RS485 serial
The RS485 standard interface enables a multi-point connection.
Between PC and the network, it is required a Serial RS232
to RS485 Converter (CV3285M).
For connection between the different devices, it is requested
a twisted pair cable. The maximum recommended length for a
connection is about 1200m at 9600 baud. For longer length
it is suggested to set a lower baud rate or to use a lower
attenuation cable or better to mount signal
repeaters (RPT85). The repeater is also suggested when
more than 32 meter per line are mounted.
CV3285M serial RS232 to RS485 converter
· Galvanic insulation between network and PC
· Communication up to 32 devices
The CV3285M is a serial converter from the standard RS232
to RS485 (RS422 selectable). CV3285M automatically detects
the signal direction. This guarantees complete compatibility
with all Microsoft WINDOWS® versions and with all passive devices, such
CV3285M guarantees galvanic insulation between
the two interfaces, so that ground loop problems are prevented
and safety is assured for the PC user.
