The wizard includes a standard File Open dialog box, which will prompt you to select or browse for
the configuration file to be restored. Previously saved configuration files have a “.cfg” file extension.
When you click the Open button in the File Open dialog box, the BACdrop Setup Wizard will read
the configuration file from the specified disk and write it to the BACdrop gateway.
Change Timing Parameters Tool (Advanced Users Only)
The Change Timing Parameters tool allows advanced users to adjust two timing limits for read and
write operations. Default values are preprogrammed and, in most applications, should not require
adjustment in the field. The timing parameters are part of the BACdrop configuration file.
Discussion of the timing parameter functions is beyond the scope of this document. Only qualified
and trained technicians should attempt to adjust them after consulting with personnel in the McQuay
Controls group.
Working With the MicroTech Network
Through the BACdrop Gateway
This section describes the BACdrop Setup Wizard tools that allow you to interact with the MicroTech
network from the BACnet side of the gateway. You can verify communications to each MicroTech
controller, and you can read from and write to each controller by using its BACnet objects. A data
packet logging tool allows advanced users to monitor network messages sent between the BAS and
the BACdrop gateway.
All of these tools can be found under the BACnet Network menu:
Network Diagnostic
Scans the MicroTech network for each controller defined in the
BACdrop configuration file. If a controller is found, its software
IDENT is read and displayed. If a controller is not found, an error
message is displayed. This tool is used to verify network
communications during network commissioning.
Network Read/Write
Allows you to read from or write to memory locations within
MicroTech controllers by using their mapped BACnet objects.
Log BACnet Packets
Allows you to log BACnet data packets or all LAN packets to a file.
This tool is useful only to advanced users.
To use a tool on the BACnet Network menu
•
On the BACnet Network menu, choose one of the above tools.
The tool’s wizard starts and leads you through the setup. You will be asked to verify cable
connections and the Ethernet adapter to be used. The Network Diagnostic tool will also ask about
the COM port to be used. See below for more information on each tool.
PC Hardware and Cabling Configurations
To use this set of tools, your PC must be equipped with an Ethernet adapter that has a 10BaseT
connection. Every tool in this set uses an Ethernet connection, but the cabling configurations vary
with the tool used.
For the Network Diagnostic tool, a direct Ethernet connection and a serial cable connection is
required. A direct Ethernet connection can be made with a 10BaseT crossover (or null) cable or with
two standard 10BaseT cables and a hub. See Figure 19.
