Page 3: General Information
1.1. WARRANTED INFORMATION ADA-401WA converter is covered by a two year warranty from date of sale. In case of being damaged it will be repair or the damaged component will be replace. The warranty does not cover damage caused from improper use, materials consumption or any unauthorized changes. -
Page 4: Description
Over-voltage protection on each RS-485 line was made on base over-voltage LEDs and fuses. It is possible to connect 32 ADA-401WA devices operating in linear topology to RS-485 bus. It is possible to connect other 32 converters by applying ADA-4040 repeater. -
Page 5: Application
3.2. CONNECTION TO PC ADA-401WA can be connected to RS232 port or USB of PC by the use of additional converter eg. RS232 to RS485 (ADA-1040) or USB to RS485 (ADA-I9140). The connection is made via RS485 bus or RS422 bus, as on the figure bellow. -

Page 7: Line Termination
9600Bd. The Line Termination resistor should be used if the distance is over 1000m @ 9600Bd or 700m @ 19200Bd transmission, the resistor can be necessary if there are problems with the transmission correctness. Example connection of Rt to screw terminal block of RS485/422 interface ADA-401WA are shown on Fig. 6 & 7. 3.4. CONNECTION TO 1-WIRE NETWORK 3.4.1. -
Page 8: Power Supply
Can be set also some of parameters the internal interface of converter, for communication with DS2480B circuit. First should be set the number of COM port for communication with the converter, then readout the configuration from ADA-401WA memory using the button [Read converter configuration] and make the proper changes of interface setting. -
Page 9: Data Transmission Diagnostics
(zeroing of counters in the memory of the converter) press [Delete transmission errors]. In case of parity errors or frame errors, should be checked the ADA-401WA converter's configuration and correctness connection of RS485 and 1-WIRE bus to the converter ports. -
Page 10: Emergency Firmware Update
SW1-2 After micro-switch setting, should be restarted the ADA-401WA, by turning OFF and then ON the power supply. The yellow LED will light continuously and the converter will be in Emergency Firmware Update mode. Now follow the description in point FIRMWARE UPDATE. -
Page 11: Factory Default
Converter receive only 950 characters and in case of transmitting of frames containing more than 950 bytes is ignoring them. ADA-401WA was equipped with separate buffers for RS485 port and 1-WIRE therefore converter can operate at full duplex mode on RS-485 4-wire bus. -
