7.1 RS485 interface with IsoData protocol (IRDH275)

Data transmission is continuously carried out and can neither be interrupted
by the data slave station nor be influenced in any other way. This protocol
cannot be used in combination with the BMS protocol.
For data evaluation via PC or Laptop, the terminal software "IsoData" and an
interface converter of the ASCII-RS485/RS232 type is required. To obtain the
software, please contact Bender Service. Contact details are found on page 8.
Interface data:
RS485 interface galvanically isolated from the device electronics
Connection to terminal A and B
Maximum cable length 1200 m
Transmission protocol 9600 baud - 1 start bit - 1 stop bit - 8 data bit
After each valid measurement, the following data block is provided:
IRDH275_D00122_03_M_XXEN/05.2017
- RS485 and IsoData protocol
- galvanically isolated
- ASCII, unidirectional
