Material List
SETUP
The QD2040c Building Controller is recommended to be factory programmed by submitting customer specific networks
at the time of order so no additional software configuration is required.
If a QD2040c was purchased without pre-programming it will be shipped with DHCP client enabled. The configuration
page is available through a browser for additional configuration of the QD2040c local IP address. Contact your network
administrator to determine the local IP address (refer to the MAC address available on the product label).
Factory IP Network Address Configuration
The QD2040c is designed to be hung on a wall using the included mounting bracket and mounting screws. It may also be
set on a shelf or table. 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 exces-
sive dust, heat sources, moisture, or direct sunlight. The ideal environment is a server room. The temperature of the room
cannot exceed 77ºF (25ºC), good ventilation is mandatory.
COM 1-2: Connect an RS-485 Network (Refer to RS-485 Controller Network Wiring & Setup below)
USB PORTS 1-4: Connect an RS-485 Network via a USB to RS-485 converter (QD1010), or connect a TCS ZigBee network
Power: Attach the included power supply to the back unit and insert the power plug into a 120 VAC non-switched outlet
(do not use socket). Upon connection the unit may power up automatically. If it does not, press the power button.
Cloud Connectivity Ethernet Port: Connect an Ethernet cable to the specic port on the specied switch on the LAN (this
information is determined by your local network administrator or IT department). If a cellular modem is used, connect the
Ethernet cable to the Ethernet port on the Cellular Modem.
Local Management Ethernet Port: Used for local onsite management of the QD2040c device using a computer with a
network interface which can be connected to setup and edit the controller.
Remaining connections are unused and should not be plugged in.

CONNECTIONS
All controls connected to the network will need to 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 either be done from
the face of the controller using the keypad and display, or using TCS Insight software. TCS Technical Support can access
the QD2040c online and change the address of a controller.
Use 22 AWG, twisted shielded 3-conductor cable for network wiring. Network wiring should start at one controller and
go to the next and then go to the next, and so on until the final 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.
A bus resistor (120 Ohm) is to be placed at the end of the bus network between the “A” and “B” wires. The bus resistor
(120 Ohm) may be placed at the QD2040c, between the “A” and “B” wires if the controller is at the end of the network.
If the QD2040c will be in the middle of the network, do not wire in the terminating resistor on the QD2040c terminal
block (See 2 below). Finally, connect one end (ideally the furthest end from the QD2040c) of the shield wire of the
network wiring to earth ground. TCS recommends a 250 milliseconds time out period for all wired networks, and 1000
milliseconds for wireless networks. If you encounter timeout errors please contact tech support.
NOTE: In the middle of the network, all network wiring shields should be twisted together and taped off to prevent
accidental grounding. More than one ground on the network wiring can result in communication failure.
NOTE: A maximum of 2 terminating resistors can be used. See Figure below.

DEVICE CONFIGURATION
RS-485 Network - Port Configuration
Here you will configure each of the COM ports for this site. Typically, you will leave Auto Detection of Controls on All
Ports enabled so the QD2040c will find and add the controller as they are included on one of the networks (wired or
wireless). If disabled, new controllers must be added manually in Ubiquity Cloud.
The communication ports are automatically detected once the QD2040c is powered up. Once detected each COM port
needs to be configured to ensure proper functioning of the network on each port. Each port can be enabled or disabled
from the drop down menu.
You must also select the proper protocol being used on each port. The current protocol selections from the drop down
menu are TCSbus or Modbus. You must also select the communication baud rate for each port. This setting must be
the same as all of the controllers on that port. You can also adjust the Time-Out Period for each port. TCS recommends
250ms for wired networks and 1000ms for all wireless networks.
Baud Rate: (Default 9600) is the communication speed of the serial bus. You must also select the communication baud
rate for each port. This setting must be the same for all of the controllers/devices on that port.
Time-Out Period: (Default 200) is the Time-Out period for each port.
Autodetection Range: (Default 0,255) Is the lowest and address to start polling and the highest address polled during the
autodetected sequence.

DEVICE CONFIGURATION
COMMUNICATION INFORMATION
This section contains settings which control how the QD2040c connects out through the LAN or WAN to the Internet.
All of these settings are determined by your local network administrator or IT department. The correct settings, network
permissions, and port openings (WAN Outbound, ports 80, 443, 8443) need to be verified with them prior to installation
and connecting to the local network.
Communication Options
The QD2040c supports both static IP and Dynamic Host Configuration Protocol (DHCP) IP address allocations. Enter the
Central Server Location, typically www.ubiquitysystems.net by clicking the “Set Ubiquity Domain Name” button. Select
whether to enable or disable special options. Enter host name if needed (typically left blank).
Network
Select the desired IP allocation (DHCP or static IP addressing) to be used. When using static IP, it is necessary to enter
the IP Address, Gateway, Subnet, DNS1 and DNS2 settings. The IP settings will need to be established by the LAN/ WAN
network administrator prior to installation. When utilizing DHCP addressing, the IP address settings are automatically
assigned when communication is established.

CONTROLLER VIEW
This section allows you to see what controllers have been found by the QD2040c and view each controller’s address,
model, and communication status. The state field will show AUTO-DETECTED initially when found by the unit and
CONFIRMED once the controller has been recognized by the Ubiquity central 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 button with the arrow on it on the right side of the Controller View title bar will refresh each controller’s status.
SYSTEM COMMANDS
In this section you are able to set a couple of system flags for the QD2040c itself. “Reboot Unit” sets a flag which will
shut off and restart the QD2040c within a 5 minute Cycle. “Check for Update” contacts the Ubiquity Central 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 may reboot.
NOTE: The “Check for Update” command requires that the QD2040c have Internet access to retrieve the update patch.

Troubleshooting
LED Description
Three LEDs on the QD2040 allow the occupant to view the current operating status of the QD2040c.
Power
This LED will be on when the QD2040c is properly powered.
LAN
Two LEDs are built into the RJ-45 LAN connector.
• Link LED (Green)
• Data Rate LED (Green/Yellow)
The LEDs indicate when the board is powered up and the LAN subsystem is operating. If Link Green is off then LAN link
is not established. If on, LAN link is established. If blinking LAN activity is occurring.
If Data Rate Green/Yellow is Off, 10 Mbits/s data rate is selected. Green means the 100 Mbits/s data rate is selected.
If yellow, 1000 Mbits/s data rate is selected. One light should blink intermittently and the other should remain on all the
time. The blinking light represents communications. The other solid light indicates a proper Ethernet connection.
RS-485 Ports (COM 1&2)
Each port has the proper biasing resistors as specified by the BACnet standard. Each port is also optically isolated, which
cleans up the signal and also protects the unit from taking stray voltage off the RS-485 Lines.
A set of LEDs allow the occupant to view operational status of the serial communication integrated board. Each port has
two LED’s to the right of the terminals:
GREEN – indicates transmitting (Tx)
YELLOW – indicates Receiving (Rx)
Additionally, a single red LED indicating the serial ports are operational, is located inside the enclosure behind the
terminals
