Introduction
Congratulations on choosing the TCS QD2040c Ubiquity Cloud Building Manager! The QD2040c is a compact, versatile
network controller that seamlessly connects with Ubiquity Cloud™ via TCSbus or Modbus.
This manual includes all the information you will need to properly install and set up your QD2040c. As most units come
precongured, you will most likely only need to read the Installation section of this manual and you can skip the Congura-
tion section. However, some customers do order their units without being congured beforehand; for those customers, we
include the comprehensive Conguration section which contains essential information they will need to set up the unit.
If you have any questions regarding your QD2040c or your network, do not hesitate to contact TCS Technical Support at
800-288-9383, ext. 2.
Material List
• QD2040c Ubiquity Cloud Site Gateway
• External Power Supply
• Wall Mounting Bracket
Mounting
The QD2040c is designed to be hung on a wall via the mounting screw holes in each unit. It may also be set on a shelf or
table. If mounting on a wall, do not allow the mounting screws to touch the circuit board inside the enclosure.
When selecting a location to mount the QD2040c, be sure to allow space for cable connections. Locate the QD2040c away
from excessive dust, heat sources, moisture or direct sunlight. The ideal environment is a server room. The temperature of
the room should not exceed 77ºF (25ºC); good ventilation is mandatory.
Input Connections
Refer to the “QD2040c Power and Communication Connections” on page 4 for the following input connections:
Power: Attach the included power supply to the front of the QD2040c and insert the power plug into a 120 VAC socket.
Upon connection the unit should power up automatically If it does not, press the Power button once.
Ethernet: Connect an Ethernet cable from your network to the Ethernet LAN port (C) Do NOT connect to port L, which is
reserved for Admin only. If you are using a cellular modem, connect the Ethernet cable to the Ethernet port on the Cellular
Modem.
RS-485 Network: Connect an RS-485 network to one of the COM ports.
USB PORT 1-4 (Optional): Connect an RS-485 network via a USB cable to an RS-485 converter (QD1010), or connect a
TCS ZigBee network via a wireless gateway (QW1010).
NOTE: The remaining ports on the QD2040c are unused or reserved for Admin only.

QD2040c Power and Communication Connections
Power and Communication Connections
RS-485 Network Wiring
All controllers connected to the network must be programmed with the same communication baud rate as well as a
unique communication address from 0 to 255, excluding 248. On controllers with displays, this can be done from the con-
troller using its keypad and display, by using TCS Insight software, or by calling TCS Technical Support (800-288-9383, ext.
2). TCS Technical Support can access the QD2040c online and change the address of a controller.
Use 22 AWG, twisted shielded two-conductor or three-conductor cable for network wiring. Network wiring should start
at one controller and go to the next and then go to the next, until the nal controller is reached. Wiring is such that all “A”
wires are connected to “A” wires, all “B” wires are connected to “B” wires, and all “REF” wires are connected to “REF” wires.
NOTE: “A" refers to the negative (–) RS-485 connection and “B” refers to the positive (+) RS-485 connection.
A 120 Ω terminating resistor should be placed at each of the two ends of the network directly across the “A” and “B” wires.
• If the QD2040c will be at one end of the network, hard-wire a 120 Ω terminating resistor across the “A” and “B” termi-
nals of the QD2040c (See “Three-Wire Network Wiring” on page 5).
• If the QD2040c will be in the middle of the network, do not wire in the terminating resistor on the QD2040c terminal
block.
Connect one end (ideally the furthest end from the QD2040c) of the shield wire of the network wiring to earth ground.
NOTE: If you encounter time-out errors, contact TCS Technical Support (800-288-9383, ext. 2).

Installation
Startup
1. Verify all RS-485 connections from the controller network to the QD2040c are complete.
NOTE: Refer to “QD2040c Power and Communication Connections” on page 4 for steps 2 through 5 below.
2. Verify that all 24V power wiring to the controller network has been completed; all controllers are powered on and
each controller has been programmed with a unique RS-485 address.
3. Connect one end of the Ethernet cable to the Ethernet port (C) on the QD2040c, and the other end to the network port
provided by the customer, or to a cell modem (if utilized).
4. Connect the power source to the QD2040c and apply power. If your QD2040c was precongured by the TCS factory
or another user, it will automatically go online and contact Ubiquity Cloud.
5. You MUST call TCS Technical Support (800-288-9383 ext. 2) to verify connection and activate the unit.
6. If your QD2040c was not ordered precongured: You can congure it at this time. See the Conguration Section on
page 9.
Troubleshooting
Power LED Does Not Light Up
Be sure that the 12V, 5A tip positive power supply module included with the QD2040c is plugged in to a 120VAC outlet
that has power.
No Communications with Controllers on the Network
Make sure the baud rate selection for the QD2040c is set to match the baud rate of all the controllers on each port net-
work (the default communication speed of the serial bus is 9600). All controllers on the network must have a unique ad-
dress, excluding the reserved address ‘248’. All controllers on any given port must be of the same type, whether Modbus
or TCSbus. Also, each port must be congured for the appropriate type of communication.
Check the network wiring, making sure to follow polarity; the wire that goes to A must go to A in all devices, as well as the
wire that goes to B and REF.
No LAN Link to the Internet
Verify the network cable is connected correctly and make sure the LEDs next to the Ethernet jack are properly illuminat-
ed. For example, a solid green LED at the RJ-45 LAN connector usually indicates that the QD2040c is either connected or
receiving a signal. If the green light is ashing, this is an indication of data being sent or received.
If there are no lights, the QD2040c may not be connected properly, or may not be receiving a signal from the network. If,
after checking the connections, the LED indicators are still off, the network adapter, port, or cable may be defective.
If there are lights but there is still no communication, this could be because the network communication is not set properly
or there is a bad rewall proxy setting. Contact your IT department for support, or contact TCS Technical Support (800-
288-9383, ext. 2) for assistance.

No Communication with RS-485 Ports (COM 1 and 2), Ubiquity Time-out, or No Data
Verify each port on the QD2040c has the proper biasing resistors as specied by TCSbus and Modbus standards. Verify
each port is also optically isolated, which cleans up the signal and protects the unit from taking stray voltage off the RS-
485 lines.
A set of LEDs on each of the RS-485 ports on the QD2040c allow the building occupant to view operational status of the
serial communication integrated board:
• GREEN – blinking indicates transmitting (Tx)
• YELLOW – blinking indicates receiving (Rx)
If neither of these lights are functioning, there could be a bad connection, a bad cable, a bad ground, or a bad component.
Contact TCS Technical Support (800-288-9383, ext. 2) for assistance.

Configuration
IMPORTANT: If you ordered your QD2040c preconfigured by TCS, which is typical,
you can skip this section! The Configuration section is for customers who did not
order their QD2040c preconfigured by TCS, or who need to reconfigure their unit.
Introduction
The QD2040c utilizes an internal Gateway to communicate with Ubiquity Cloud and the attached device networks. This
Gateway can be congured locally by connecting a laptop directly to the device, or by connecting a monitor and keyboard.
When using a laptop, you can congure the Gateway through the QD2040c’s internal web page. When using a monitor and
keyboard, you can congure the Gateway via the text-based Command Line Interface (CLI).
NOTE: All Ubiquity Cloud services are accessed by logging into the Ubiquity Cloud Server (www.ubiquitysystems.net),
not by using the internal Gateway.
The unit is precongured with a default Gateway login and password, which is supplied to customers upon request. It is
the customer’s responsibility to congure a custom login and password. Contact TCS Technical Support (800-288-9383,
ext. 2) for information on managing Gateway login credentials.
Gateway Conguration Via Laptop
Once you have made a connection and have logged in (see “Appendix A: Local Management Port” on page 18) you can
congure the operation of the unit by selecting the proper parameters for your application.
If you are unable to access the configuration page, contact TCS Technical Support (800-288-9383, ext. 2) for assistance.
Installation Information
The Hardware Identity section contains unit-related information used to uniquely identify the unit when it is being serviced
in the eld. The Software Status section contains software/application-related information that identies the level of
patching of the unit. The Site Time is used by the local network and the QD2040c until the Ubiquity Cloud Server performs
a time synchronization with the site.
NOTE: Be sure to set the correct time zone so that the site will correctly adjust the time during future time synchroniza-
tions with Ubiquity Cloud.

Application Information
RS-485 Network - Port Conguration
Both RS-485 communication (COM) ports are congured using this interface. While the COM ports are automatically
detected once the QD2040c is powered on, each active port will need to be congured to ensure proper functioning of the
network. Ports can be enabled or disabled from the drop-down menu as well.
NOTE: Secure Sockets Layer (SSL) requires port 443 to be open.
Protocol: Select the communications protocol being used on each port. TCSbus is selected by default.
Baud Rate: This is the data transmission speed on the network. The Baud Rate must be the same selection for the port
conguration as it is on every device communicating to that port.
Time-out Period: This is the number of milliseconds the port on the QD2040c will wait for a response from the network
devices before determining that a device is not communicating, or has “timed out.” Select the time-out period for each
port. TCS recommends TCSbus and Modbus set at 200 ms for wired networks.
Auto-detection Range: (Default 0, 255) This is the lowest address to start polling and the highest address to stop polling
during the auto-detected sequence.

Clicking the green button with the arrow on it on the right side of the Ubiquity Connection Status title bar will refresh the
connection status.
Controller View
This section allows you to see what controllers have been found by the QD2040c and view each controller’s address, mod-
el, and communication status. The state eld will show AUTO-DETECTED initially when found by the unit and CONFIRMED
once the controller has been recognized by the Ubiquity Cloud Server. This information allows the installer to verify that
each controller has been found by the QD2040c and is communicating with the local network. Clicking the green Refresh
button on the right side of the Controller View title bar will refresh each controller’s status.
System Commands
This section describes how to set up system ags for the QD2040c. “Reboot Unit” sets a ag which will shut off and
restart the QD2040c within a ve-minute cycle. “Check for Update” contacts the Ubiquity Cloud Server for any updates
relevant to its particular model number and software version. Once the update has been downloaded, it is automatically
applied, and the unit will reboot if necessary.
NOTE: The “Check for Update” command requires that the QD2040c have Internet access to retrieve the update patch.
Gateway Conguration via CLI
When you connect to the QD2040c using a a keyboard and monitor (See “Appendix C: Monitor and Keyboard” on page
27), you can congure the Gateway parameters for your site by using the built-in CLI.
1. To establish a connection to the CLI, you must enter a login user name and password. If you have not changed the
user name and password, you must enter the default credentials.
NOTE: If you do not have the default credentials for this unit, contact TCS Technical Support at 800-288-9383 ext. 2 for
assistance.)
2. Once logged in, type in “tcssetup.” This will open the CLI (see “Command Line Interface Screens” on page 16).
3. Scroll to each eld that you want to change by pressing the “Enter” button.
4. Type in new values on any eld as needed. Pressing “Enter” will save new value, or keep current value, and advance
to the next eld.
5. Once the nal “Secure Mode” section is nalized, the unit will automatically apply the new conguration and update
the unit within ve minutes.
NOTE: After you have finished configuring the Gateway, you can revert your laptop back to its original DHCP settings, if
desired. See “Appendix B: Revert Back to DHCP Settings” on page 24.
