 "summary": "KGTW-BAC is a DIN-rail Modbus RTU to BACnet gateway for RHOSS terminal units. With the KCMS_IP or KCMS_MSTP profile each KCMS fan coil shows up as a separate BACnet device with the 20 objects below: temperatures, setpoint, mode and fan speed commands, on/off, economy mode and an alarm code. BACnet IP and BACnet MS/TP are both available.",

  "The guide marks writable objects W and read-only objects R.",
  "On the KCMS, Modbus RTU is turned on with parameter P54 = 1 and the node ID is parameter P69 (1-207); the line runs at 9600 baud, 8N1."
