2.2. DESCRIPTION
ADA-4010A addressable converter is device solving the problem of connecting no addressable devices equipped with the RS232
interface to multi-point RS485 bus by adding the address to RS232 device.
At the same time converter turns RS485/422 standard to RS232 standard with possibility of interference with the format of transmitted
data. It can be set baud rate, number of data bites, control parity and number of stop bits depend on configuration. The setting can be
different for RS232 port and RS485/422 port.
It is not required for operating, power supply form RS232 port, converter supports asynchronous baud rate up to 230,4 kbps through
one or two pairs of twisted cable of RS485/422 interface. ADA-4010A is equipped with screw terminal block for connection of RS232,
RS485/422 and power supply. Converter uses RX, TX, GND signals and RTS signal of RS232 is used for data flow control type: RTS-
ON, RTS-TOGGLE, RTS-OFF and CTS signal is not use, DTR signal is connected with DSR. Other signals are not connected. If is not
needed looping above signals, can be not connect DTR to the terminal block.
Surge protection on each RS485/422 lines, has been made on the base of diode suppressors and fuses.
