5.5. FACTORY DEFAULT
In case of faulty functioning of ADA-4040A, like:
- no communication in the configuration mode,
- transmission errors on RS485/422 bus,
can be restored the factory default setting of the converter internal registers.
Factory default
Parameter
RS1 interface
RS485/RS422 RS2 interface
RS485/RS422
Converter address - Enable unset
Converter address – Address no active
Baud rate 9600bps 9600bps
Data bits 8 8
Parity Non Non
Stop bits 1 1
Interval between frames in bytes 4 4
Data flow control DE-TOGGLE DE-TOGGLE
Set SW1 microswitch mode as in the table below.
SW1-1 SW1-2
OFF ON
Disconnect the power and after while connect again the power. After that, will be loaded the factory default setting to the converter
internal registers.
After this operation, the converter parameters should be set again for operating in the application.
Set micro switch SW1 to run mode (Yellow LED will be OFF) as shown in the table below.
SW1-1 SW1-2
OFF OFF
5.6. DIAGNOSTICS DATA TRANSMISSION
To readout diagnostics set SW1 to configuration mode (see pt OPERATION MODE).
Correctness of transmission proceed on RS1 and RS2 can be checked by readout the errors list by ADAConfig Software from the
converter memory. Frames error counter will be increased, in case of: improper speed set compared to real speed of data
transmission. Parity error counter will be count the errors which can arise in case of misrepresent bytes in transmitted sign. This
counter will not work in case of disable control parity. For checking this counters press the button [Read transmission errors], and to
delete (zeroing of counters in the memory of the converter) press [Delete transmission errors].
In case of parity errors or frame errors check ADA-4040A converter's configuration and correctness connection of RS485 network to
RS1 port and addressable device to converter's RS2 port.
When diagnostic is finish, set SW1 micro-switch to run mode (see pt. OPERATION MODE).
6. OPERATION
The ADA-4040A converter can operate in to two modes: not addressable and addressable.
6.1. OPERATION IN NON ADDRESSABLE MODE
In this mode ADA-4040A operates as baud rate converter and data format converter and lets to set different baud rates and data
format on RS1 & RS2 interfaces. It lets connect to RS485 network old devices operate with non-configure baud rate and data format,
on which operate devices with different baud rate or data format.
6.2. OPERATION IN ADDRESSABLE MODE
In this mode ADA-4040A operates as baud rate converter and data format converter and lets to connect no addressable devices with
RSRS485/422 interface, transmitting data at different rates and formats of data frame to the RS485 bus, in the process of enabling the
cooperation with addressable devices.
Example connections of ADA-4040A are shown on figures below.
Frame of protocol for no addressable RS485/422 devices, connected to RS2 of ADA-4040A should be created in the following way:
ADDRESS ADA-4040A FRAME OF NO ADDRESSABLE DEVICES
Where::
ADA-4040A ADDRESS - one byte of address from 1-255 scope, - set in the memory of ADA-4040A
during configuration in use of
ADAConfig,
FRAME OF NO ADDRESSABLE DEVICES - free sequence of bytes containing the appropriate frame of device, connected
to RS2 port. Not longer than 950 bytes.
