In the configuration mode yellow LED located by SW1 micro-switch will blink with frequency 1 Hz. Start the ADAConfig Software and
make the configuration of transmission parameters for RS485 interface of module and setting of address seen on RS485-MODBUS
bus. First, should be set the number of COM port for communication with the module, then readout the configuration from ADA-
DIOC40 memory using the button
[Read converter configuration]
and the proper changes of interface setting.

5.2.1. CONFIGURATION OF ADDRESSING MODE
For ADA-DIOC40 module the addressing mode is permanently enabled, therefore should be set a proper module address from range
1 - 247.
5.2.2. CONFIGURATION OF BAUD RATE AND DATA FORMAT
RS485 communication interface of module, can be set as below:
a/ baud rate (kbps): 0.3, 0.6, 1.2, 1.8, 2.4, 4.8, 7.2, 9.6, 14.4, 19.2, 28.8, 38.4, 57.6, 76.8, 115.2, 230.4,
b/ number of data bites:: 5, 6, 7, 8,
c/ control parity: no control, parity control, control of none parity,
d/ number of stop bits: 1, 2,
e/ frame spacing – range from 4 to 255 (silence time as frame's end).
5.2.3. CONFIGURATION DATA FLOW CONTROL
In the section
Data flow
control
for RS485/RS422 interface, can be set –
not available at present
:
- signal DE – Off - RS485/RS422 interface operates only in receiving data mode,
- signal DE – Toggle - RS485 interface operates in receiving & transmitting data mode for RS485 bus 2-wires and 4-wires,
- signal DE – On - RS485/RS422 interface operates in RS422 mode,
