3. Mounting the ProtoNode
Bacharach recommends mounting the ProtoNode inside the MultiZone
enclosure on the inside of the MZ door (see figures below) using the
included hardware. As an alternative, the ProtoNode may be mounted at
an appropriate location near the MultiZone using the mounting holes on
the ProtoNode enclosure.

4. Connecting the Power Supply
The ProtoNode can be powered by 9-30 VDC or 12-24 VAC. The
ProtoNode converter kit contains a power cable so that the ProtoNode
can be powered by the MZ. The power cable that is supplied with the kit
is meant to replace the existing MZ cable. It plugs into J3 of the main
board and J5 of the power supply board (see Figure 6). The 12V and
ground wires of the new cable have been lengthened, and are unterminated so that they can be inserted into the terminal block connector
on the ProtoNode. The kit also contains a green cable for grounding.
Connections are illustrated in the photo and chart below. (See Figure 5
and Figure 7.)

NOTE: If you choose NOT to power the ProtoNode from the
MZ, you must supply all necessary wiring and an appropriate
power supply.
5. RS-485 Network Wiring
The RS-485 bus should be wired in accordance with the practices
described in the MZ manual and FieldServer’s ProtoNode
documentation. Connections are illustrated in the photo and chart below.
Network wiring is not supplied in this kit.

6. Network Configuration
The ProtoNode is factory-configured with the following defaults.
• Default IP Address 192.168.1.24
• Default Subnet Mask 255.255.255.0
If a different IP address or subnet mask is desired, or for other
configuration settings, please refer to the appropriate FieldServer™
documentation.
7. Supported MODBUS Registers
The following is a list of the MZ’s MODBUS registers that are supported
by the current revision of our ProtoNode configuration files.
WARNING: Writing to the refrigerant type setting should
only occur when the MZ is being configured. Frequent writes
should be avoided.

NOTE: Each zone's refrigerant type is assigned two BACnet
objects: an Analog Value and an Analog Input. The Analog
Value is used to write the refrigerant type. The Analog Input
object is used to read the refrigerant type.
