Introduction
Congratulations on choosing the TCS QD2040b! The QD2040b is a compact, versatile network controller that seamlessly
connects with the Ubiquity Cloud™ via TCSbus or Modbus.
This manual includes all the information you will need to properly install and set up your QD2040b. 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 QD2040b or your network, do not hesitate to contact TCS Technical Support at
800-288-9383, ext. 2.
Material List
• QD2040b Ubiquity Cloud Site Gateway
• External Power Supply
• Wall Mounting Bracket
Mounting
The QD2040b 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. Do not allow the mounting screws to touch the circuit board inside the enclosure.
When selecting a location to mount the QD2040b, be sure to allow space for cable connections. Locate the QD2040b
away from excessive dust, heat sources, moisture or direct sunlight. The ideal environment is a server room. The tempera-
ture of the room should not exceed 77ºF (25ºC); good ventilation is mandatory.
Input Connections
Refer to the "QD2040b Power and Communication Connections Diagram" on page 4 for the following input connec-
tions:
Power: Attach the included power supply to the back of the QD2040b 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 to the Ethernet LAN outlet. 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 connections on the QD2040b are unused and should not be plugged in.

QD2040b Power and Communication Connections Diagram
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 QD2040b 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 QD2040b will be at one end of the network, hard-wire a 120 Ω terminating resistor across the “A” and “B” terminals of
the QD2040b (See "Three-Wire Network Wiring" on page 5). If the QD2040b will be in the middle of the network, do not
wire in the terminating resistor on the QD2040b terminal block.
Connect one end (ideally the furthest end from the QD2040b) 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).

Three-Wire Network Wiring
Follow this wiring diagram for all three-wire systems (this is common).
NOTES: In the middle of the network, all network wiring shields should be twisted together and taped off to prevent acci-
dental grounding. More than one ground on the network wiring can result in communication failure.
A maximum of two terminating resistors can be used.

Installation
Startup
1. Verify all RS-485 connections from the controller network to the QD2040b are complete.
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 on the QD2040b, 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 QD2040b and apply power.
5. If your QD2040b was precongured by the TCS factory or another user, it will automatically go online and contact
the Ubiquity Cloud. However, you must call TCS Technical Support (800-288-9383 ext. 2) to verify connection and
activate the unit.
6. If your QD2040b was not ordered precongured, you can congure it at this time. See the Conguration Section on
page 9.
The unit is now ready for operation.
Troubleshooting
Power LED Does Not Light Up
Be sure that the 12V, 5A tip positive power supply module included with the QD2040b 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 QD2040b 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 QD2040b 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 QD2040b 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.

Installation
No Communication with RS-485 Ports (COM 1 and 2), Ubiquity Time-out, or No Data
Each port on the QD2040b has the proper biasing resistors as specied by TCSbus and Modbus standards. 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 on each of the RS-485 ports on the QD2040b 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 QD2040b preconfigured by TCS, which is typical,
you can skip this section! The Configuration section is for customers who did not
order their QD2040b preconfigured by TCS, or who need to reconfigure their unit.
Gateway Conguration
The unit is precongured with a default login and password. It is the customer’s responsibility to congure a custom
login and password. Contact TCS Technical Support (800-288-9383, ext. 2) for more information on how to set up cre-
dentials.
Once you have made a connection and have logged in (see "Appendix: Monitor and Keyboard" on page 18) you are able
to 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 assis-
tance.
All Ubiquity Cloud services are accessed by logging into the Ubiquity Cloud Server (www.ubiquitysystems.net), not by
using this conguration page. This page is only used for setting up local network communications.
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 QD2040b 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.
