Introduction
The BACdrop Setup Wizard is a suite of software tools that allow you to configure a BACdrop gateway and
commission a MicroTech network. It is a 32-bit program that runs on a PC equipped with Windows 95 or
Windows 98.
The BACdrop Setup Wizard helps you accomplish the following tasks:
• Obtain a summary of pertinent system information
• Configure the BACdrop gateway
• Download software to the BACdrop gateway
• Back up a BACdrop configuration file to the PC hard disk
• Restore a BACdrop configuration file
• Change gateway timin g parameters
• Perform a network diagnostic test through the gateway
• Perform a network diagnostic test without the gateway
• Read/write to MicroTech controllers via mapped BACnet objects
• Configure MicroTech controller port speeds and port configurations
• Log BACnet data packets
Each software tool is set up as a “wizard” that takes you step by step through each task, showing you cabling
diagrams and required communications components when needed.
If you want, you can print this online user’s guide. The BACdrop Setup Wizard User’s Guide is also included as
part of Bulletin No. IM 689, MicroTech BACdrop Gateway.

Starting the BACdrop Setup Wizard
You can run the BACdrop Setup Wizard at any time. The PC does not need to be connected to a BACdrop
gateway when you start the program.
To start the BACdrop Setup Wizard
1. On the Start menu, point to Programs, BACdrop Setup Wizard, and then choose the BACdrop Setup Wizard
program.
2. Type the password in the box.
The password is “BACdrop!” (case sensitive).
3. Click OK or press Enter.
The Main screen appears.

Working With the BACdrop Gateway
This section describes the BACdrop Setup Wizard tools that allow you to interact with the BACdrop gateway by
means of a serial cable connection. With these tools you can gather information about the MicroTech network
configuration, set up or change the BACdrop configuration file, and download program files to the BACdrop
gateway. You can also back up and restore BACdrop configuration files.
All of these tools can be found under the BACdrop Panel menu:

Displays a list of the MicroTech controllers connected to the
BACdrop gateway. This command also displays the BACnet network
number and the MicroTech network number.
Displays a list of the MicroTech controllers and the address of each. It
also displays the Device instance number and the location of the
controller. You can edit the controller list with this tool.
Allows you to change the network number of either the BACnet
network or t he MicroTech network.
Allows you to download software into the BACdrop gateway.

Advanced Options:
Write Configuration
to a File
Saves a BACdrop configuration file to the PC’s hard disk or a floppy
disk.
Advanced Options:
Read Configuration
Reads and restores a BACdrop configuration file that was previously
saved to disk.
from a File
Advanced Options:
Change Timing
Parameters
Allows you to change the amount of time the BACdrop gateway waits
for responses to MicroTech network requests before timing out. These
parameters should only be changed by advanced users because
improper values can cause network problems.
To use a tool on the BACdrop Panel menu
• On the BACdrop Panel 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 COM port to be used. See below for more information on each tool.
PC Hardware and Cabling Configurations
This set of tools requires a standard serial cable (not a null-modem serial cable), which is connected between the
PC serial port and the BACdrop gateway’s “PC” port. The connector on the BACdrop gateway is a female DB9.
You should know the COM port that is assigned to the PC’s serial port. The wizard will prompt for this
information.
The first screen of each tool’s wizard is a cabling diagram that helps you set up or verify cable connections. An
example is shown below.

System Information Tool
The System Information tool displays basic information about the BACdrop gateway and its network
configurat i on. Some of the information may be useful to you, and some of it may b e useful to the BAS system
integration technicians. You can view the information, but you cannot change it with this tool.
System Information Tool, BACdrop Screen
Following are brief descriptions of each information field:
BACdrop MAC
(Ethernet) Address
BACdrop MicroTech
Address

Controller Count
Network Numbers
(decimal)
Version Information
System Error
Information
The address of the BACdrop gateway on the Ethernet network. It is
assigned by the manufacturer of the Ethernet interface adapter and
cannot be changed.
The address of the BACdrop gateway on the MicroTech network. This
address can be changed with the BACdrop Setup Wizard’s Configure
Controller List tool. Typically, a BACdrop gateway’s MicroTech address
will be 00.00.
The total number of MicroTech controllers that have been defined in the
BACdrop configuration file. Usually this number will match the number
of MicroTech controllers on the network, but there can be exceptions; for
example, a series-100 centrifugal chiller’s display processor will exist on
the MicroTech network but will not be configured in the gateway.
BACnet numbers assigned to the MicroTech network and the BACnet
network that the BACdrop gateway is part of. The BAS system integrator
may supply these numbers. They can be changed with the BACdrop
Setup Wizard’s Configure Network Numbers tool.
The version numbers of the BACdrop gateway’s program and operating
system. If necessary, the BACdrop program can be upgraded by using the
BACdrop Setup Wizard’s Download tool.
Displays any software loading errors that have occurred. For example, if
the PMF fails to load or the Ethernet adapter driver fails to load, an error
message will appear.
Click the More button to view a list of the MicroTech controllers configured in the BACdrop gateway, or click
the Main Screen button to return to the Main screen.
If you click the More button, the BACdrop configuration file is read out of the gateway’s memory and displayed.
See figure below. Each MicroTech controller that has been entered into the configuration file is shown with its
MicroTech address, controller name or type, and Device instance number. You can view the information, but you
cannot change it with this tool.
Click the Main Screen button to close the System Information tool and return to the Main screen.

System Information Tool, BACdrop Configuration File Screen
Configure Controller List Tool
With the Configure Controller List tool, you define the MicroTech controllers that the BACdrop gateway will
translate data for. This definition includes the MicroTech network address, the standard MicroTech controller
type, and the BACnet Device object instance number. You can add, delete, or modify any of this data. As an
option, you can specify a MicroTech controller’s location, which becomes the value of the BACnet Device
object’s Location property.
The main screen for the Configure Controller List tool is shown in the figure below. Before this screen appears,
the BACdrop Setup Wizard reads the configuration file out of the BACdrop gateway and makes a copy in the
PC’s memory. Any changes made to the configuration exist only in the PC’s volatile memory until they are saved
by clicking the Finish button. When changes are saved, they are written directly to the BACdrop gateway’s nonvolatile memory. (It is not possible to save a configuration file to the PC hard disk with this tool.)
