 "summary": "The Procon BAC-IP/50 is a small Mitsubishi Electric UK gateway that connects to a G-50 controller over Ethernet and serves up to 50 units as BACnet IP objects. Each unit address gets the same block of setup (_w) and state (_r) objects, named after the unit name typed into the configuration program. It does not support segmentation and its APDU limit is small, so keep read-multiple requests short.",

  "Per-unit instance = 1UUUPP: UUU = unit address 001-050, PP = point. Instances here use unit 001 (e.g. 100101). Object names start with the configured unit name (nnn).",
  "OC/BC Error Code uses 1YYY22 where YYY = unit address 051-100; 105122 shown for address 051.",
  "Points 1xxx19-1xxx21 are listed as unused and are not included.",
  "Only the group's master unit accepts commands; writes to slave addresses have no effect.",
  "AutoHeat/AutoCool are reported only when DIP switch A-1 (Auto-Detail) is on; heating/hot-water modes apply to heat-pump boilers only.",
  "Device instance, device name and object names are set only through the PC configuration program; a level-2 reset restores Device ID 10."
