2.2. DESCRIPTION
ADA-4040A addressable baud rate converter is device solving the problem of connecting no addressable devices equipped with the
RS-422 or RS-485 interface to multipoint RS485 bus, by adding the address to device connected to RS2 port of converter. Converter
enables to connect RS-422 devices to R-S485 bus without any interference. Can be adjust baud rate, number of bits, parity control or
non parity or stop bits depending on the configuration – for RS1 and RS2 ports the configuration can be different. ADA-4040A
additionally separates devices from RS-485 network and can be used as repeater of RS422/RS485 bus with speed conversion
between next segments about the length up to 1200m. The converter's galvanic separation protect system constructed on RS-485/RS-
422 network and increase functioning reliability.
ADA-4040A supports an asynchronous baud rate up to 230.4 kbps through four or two pairs of twisted-pair cables connected to screw
terminals. The converter use RX+, RX-, TX+/A, TX-/B lines for functioning. It is possible to connect 32 devises to RS485/RS422
network constructed on base of ADA-4040A, working at the half duplex or full duplex mode. Over-voltage protection on each
RS485/RS422 line was made on base of 600W over-voltage led and fuses.
