2.2. DESCRIPTION

ADA-1040D Digital Converter is used to extend RS232 ports of device using for communication signals: Tx, Rx, RTS, CTS, DTR,
DSR. The converter receives data from RS-232 port and sends them via RS485(4W) / RS422 to second converter together with
information about line condition of RS232 interface. It is possible to configure the baud rate (up to 230,4 kbps), number of data bits,
parity or no parity and number of stop bits – the setting of RS-232 can be different on both sides of RS485(4W) / RS422. Additionally,
it is possible to set baud rate on RS485(4W) / RS422 link.
Using RS485(4W) /422 bus enables to extend the RS232 device port at a distance 1200m, provides galvanic isolation between
connected devices and resistance to interference in the transmission line. Connection of RS485(4W) /422 bus is made by the use of
2-pairs twisted cable. The converter has the connection control for testing the correctness connection of RS485(4W) bus with him.
ADA-1040D is equipped with DSUB-9 female connector from RS232 interface and screw terminal block from RS485(4W) / RS422 and
power supply.  ADA-1040D  supports  data  rates  of up to 230.4  kbps  RS232 interface.  Converter  has  1kVDC or 3kVDC galvanic
isolation and 5kVDC optoisolation in signal line. It separates RS232 form RS485/RS422 interface and protect device connected to
RS232 port from overvoltage on RS485/RS422 bus and power circuit. Overvoltage protection on each RS485/RS422 line was made
on base overvoltage LEDs and fuses. ADA-1040 D should be supplied from the power supply voltage stabilized voltage range of 10 -
30 VDC and minimum power 2W.
