•
Int*10 register is in format integer*10
•
R
register is designed only for reading
•

register addresses are indexed from zero – register 0x31 is physically sent as value
0x30, 0x32 as 0x31 (zero based addressing).
Note:
In case there is a need for reading of measured values from the device with higher resolution
than one decimal, measured values in device are stored also in „Float“ format, which is not directly
compatible with IEEE754.
Protocol compatible with Advantech-ADAM standard
Control units communicate on master-slave principle in half-duplex operation. Only master
can send requests and only addressed device responds. During sending request any of slave devices
should respond. During communication data is transferred in ASCII format (in characters). Each
Byte is sent as two ASCII characters. Device supports communication speed from 1200Bd to
115200Bd, parameters of communication link are 1 start bit + eight bit data word (LSB first) +
1 stop bit, without parity.
Jumper
Jumper is located next to connection terminals. If communication protocol compatible with
standard Advantech-ADAM is selected, its function is the following:
•
If jumper during switching ON the power is closed, device always communicates
with following parameters regardless stored setting in the device:
communication speed 9600 Bd, without check sum, device address 00h
