OvervIeW
The BACnet Interface Module adds BACnet MS/TP communication capability to the Raypak TempTracker mod+
Hybrid (Hybrid) control. It does that by connecting to both, the control and the BACnet MS/TP network. All the
BACnet settings are configured through the control. The BACnet Interface Module has LEDs that can help in displaying
communication status.

ITeM LIST
• BACnet Interface Module,
• RJ45 cables (Ethernet Cable),
InSTaLLaTIOn
The BACnet Interface Module communicates with the Raypak Hybrid control using the RJ45 cable. Thus, it needs to be
installed in close proximity to the control.
• Mount the BACnet Interface Module on a flat surface next to the control.
• The module can be mounted horizontally or vertically.
• Keep the module away from extreme heat, cold, or humidity.
• Screw the module to the flat surface using the two side tabs with holes.
• No need to remove the BACnet Interface Module cover.
WIrIng
• No power wiring is required for the BACnet Interface Module. It gets its power through the
control's RJ45 connection.
• The module's MS/TP terminals are of the removal type. That facilitates easy wiring. Just
unscrew the terminal block side screws to remove the full terminal block.

BaCnet MS/TP Wiring
• Use 18# AWG Twisted Pair cable. The cable length must not exceed 3500 feet.
• Connect the MS/TP cable coming from the BACnet MS/TP network to the MS/TP terminals
on the BACnet Interface Module. Communication on the BACnet MS/TP network is polarity
sensitive.
• The ground terminal (GND) MUST be connected to the BMS Ground.
