documents to fill in the Compatible IDENTs column. For example, document BD 09-7 shows that
rooftop software codes with IDENTs ART1E06B through ART1E06D are compatible with PMF 1.07
(see Figure 8).
It is also recommended that the McQuay representative contact the BAS representative prior to
commissioning the BACdrop network to make sure that BAS engineering personnel will be using
BDIPs for the same PMF version that is on the schedule and which will be used in the BACdrop
gateway.
Projects With Two or More BACdrop Gateways
If a project has two or more BACdrop gateways, the MicroTech networks associated with them
should be separate and independent. The BAS will then have separate connections for each BACdrop
gateway. Each MicroTech network must follow the addressing rules given above in “
Assigning
MicroTech Addresses
.” Since the Device object instance and MicroTech network numbers must be
unique throughout the BAS, the Setup Wizard’s default values for these can be used on only one
MicroTech network.
Commissioning Overview
Commissioning a MicroTech network that includes a BACdrop gateway is a process that includes
four or five main tasks:
1. Configure the BACdrop gateway
2. Configure the level-1 MicroTech supervisory controller, if present
3. Verify the integrity of the communications trunk
4. Connect the BACdrop gateway to the trunk
5. Connect each MicroTech controller to the trunk and check for communications
Task 1: Configuring the BACdrop Gateway
The first task in commissioning a BACdrop network is to configure the gateway with the BACdrop
Setup Wizard. Configuration essentially involves entering the prepared address schedule into the
SBC’s memory. This allows the BACdrop gateway to properly translate and route data for every
mapped controller on the MicroTech network.
For most applications, all MicroTech controllers should be entered into the BACdrop configuration
file. The level-2 display processor in the series-100 centrifugal chiller is a notable exception. This
MicroTech controller does not have a point map in the PMF since it contains no data or command
points that would be useful to a BAS. Other exceptions may arise; for example, when a customer
does not need BAS access to a particular MicroTech controller.
To configure the BACdrop gateway
1. Connect the PC to the BACdrop gateway with the serial cable.
2. Start the BACdrop Setup Wizard.
For complete reference information on the wizard, including software installation instructions,
see the “
BACdrop Setup Wizard User’s Guide
” portion of this manual.
3. Select Configure on the BACdrop Panel menu. Then click Modify Controller List on the
submenu.
The Configure Controller List tool starts and its first screen appears. If you are sure that the serial
cable is connected, click the Next button. The second screen appears.
4. Select the COM port you are using and click Next.
The BACdrop Setup Wizard reads the configuration data out of the gateway. The third Configure
Controller List screen appears. By default, the BACdrop gateway is listed as the controller at
address 00.00. The special 00.00 address assignment defines the BACdrop as the level-1 device.
