The logger monitors the RS485 bus of the IRDH575-EDS490 system.

RS485 settings: 9600 Baud 7E1

Simplest to configure on touch-screen:

Add a Bender slave unit:

Adding it by hand on the touch-screen creates configuration:

<ConfigRs485>
      <owner>bms</owner>
      <baud>9600</baud>
      <byteLen>7</byteLen>
      <stopBits>0</stopBits>
      <parity>2</parity>
      <frameSep>500</frameSep>
      <listenTout>1000</listenTout>
</ConfigRs485>
<slaveCfg>
      <slave id="0" ip="0.0.0.0" unique="00000000_00000000" type="bender" model="" manuf="0" />
</slaveCfg>

RS485 settings are actually used by the BMS module. Touch-screen configuration sets them, but hand-crafted XML must set them correctly.

Not all BMS units are equal: they can have (and do have!) different set of channels. Whenever connecting to a new installation: please remove the existing Bender slave unit from the configuration and insert it again!
