8. Supervisory System
JUPITER units have been developed and designed so that they can be inserted within a network which is managed
by a supervision system. They are therefore compatible with the most common external BMS (Building Management
Systems).
Compatibility with external BMS
BMS on serial networks
Modbus: No limit on the number of units connected, each one has a RS485 serial card
Bacnet: Max 8 units, each one has a RS485 serial card, connected to a Bacnet Gateway
LONworks: No limit on the number of units connected, each one has a FTT10 card
TREND: possible with TREND card
Metasys: possible with integration of the database and Application Note JCI
BMS on TCP/IP (UTP) networks
SNMP: Max 16 units, each one has a RS485 serial card, connected to a Webgate
SNMP: No limit on the number of units connected, each one has a TCP/IP (Pcoweb)
Bacnet: No limit on the number of units connected, each one has a TCP/IP
HTML: No limit on the number of units connected, each one has a TCP/IP
