 "summary": "The MarleyGard LINK is an add-on enclosure with a Contemporary Controls BAScontrol22C I/O module that turns status contacts and 4-20 mA signals from a Marley tower control panel into BACnet/IP objects. It is a monitoring interface: inputs cover vibration, gearbox oil level, basin level and temperature, makeup water, basin heater, and on CoolBoost fluid coolers the spray pumps and dampers. Marley VFDs with a LINK interface connect over Ethernet separately.",

 "notes": [
  "This is Marley's 'typical' input assignment; the module is programmed per job, so the actual points vary.",
  "CoolBoost fluid cooler panels use a second I/O module (Module 2), a separate BACnet device whose instances overlap Module 1's.",
  "AI 8 VIB_LVL_XMTR is listed twice in the guide (panel- or switch-powered transmitter); it is one object.",
  "Binary inputs use normally open field contacts unless noted.",
  "The table has no access column; all objects are inputs and are marked read-only."
