8 stages with lockout inputs . The Multi-MOD Platinum can manage the Extension
panels using an RS485 connection .
• Each extension is supplied with all the necessary cables to connect to the
Multi-MOD Platinum and the other extension . The Round-to-Round cable
connects one enclosure to the other (HT# 900065-00) .
• The Flat-to-Round cable connects the main PCB board to the enclosure
(HT# 900048-00) .
• A set of dip switches on the back of the Extension Module is used to configure the
Extensions ID . See Dip Switch settings on the right .
• The connection from the Multi-MOD to the Extensions can be either in parallel or
in series . See diagrams
To connect to the Extension, use the RS485 connector on the Multi-MOD's main PCB
board . DO NOT use the RS485 connector on the BACnet communication board
• Note that, Extension panels do not come with Modulating Output Cards or relays .
These items must be purchased separately .
