Congratulations on choosing the TCS QWL4.1 Integrated Building Manager! For facilities managers responsible for
multiple sites across multiple geographic locations, the QWL4.1 Integrated Building Manager provides the tools to
increase energy savings, reduce operational and maintenance costs, provide better indoor air quality, and increase
occupant comfort.
The QWL4.1 Building Manager utilizes Ubiquity Cloud™ building management technology, a QD2040d Panel Gateway, an
SLQ218 Lighting Controller, and an SEQ100 Pulse Meter for continuous monitoring of electrical, gas, and water usage.
This manual includes all the information you will need to properly install and set up your QWL4.1 . It is divided into four
sections:
• Installation: The Installation section covers the initial mounting, input wiring and connection of the QWL4.1 to your
network of control devices. Read and throughly understand this section before beginning the actual installation of the
unit.
• Gateway Conguration: Most units come with the Building Manager’s Gateway precongured; if your unit’s Building
Manager was precongured by TCS, you can skip this section. However, some customers order their units without
being congured beforehand; for those customers, we include this section which contains essential information
necessary to set up the Building Manager’ Gateway.
• Lighting/Pulse Meter Programming: Lighting and pulse meter programming can be accomplished via Ubiquity Cloud.
Read the Lighting/Meter Programming section to learn the basics of properly programming the SLQ218 Lighting
Controller and the SEQ100 Pulse Meter to your site specications.
• Appendices: Appendices A, B, and C provide supplemental information regarding connecting a laptop or keyboard
and monitor directly to the QWL4.1 for local programming and/or conguring the components of the QWL4.1.
Appendix D provides information on using TCS Insight software, a service tool that can be used to program the QWL
locally. TCS Insight is a very powerful service tool that should be used only by trained technicians.
If you have any questions regarding your QWL4.1 or your network, do not hesitate to contact TCS Technical Support at

RS-485 Controller Network Wiring & Setup
The QWL4.1 can handle as many as 64 connected controllers on each port, including COM and serial ports. 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. The baud rate is programmed onsite locally through the monitor
and keyboard, or through remote access through the network. On controllers with displays, this can be done from the
controller 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 QWL4.1 online and change the address of a controller.
Network Wiring
The QWL4.1 has a serial board with two RS-485 ports that will accept Modbus and TCSbus Connections. These are the
recommended ports to use for your controller networks.
Recommended RS-485 port locations on serial board
NOTE: There is an additional RS-485 port on the Lighting Control/Pulse Meter Panel labelled “External RS-485”; however,
that port will only accept TCSbus.

Installation
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 QWL4.1 will be at one end of the network, hard-wire a 120 Ω terminating resistor across the “A” and “B” terminals
of the QWL4.1 (See Three-Wire Network Wiring on page 11).
• If the QWL4.1 will be in the middle of the network, do not wire in the terminating resistor on the QWL4.1 terminal block
Connect one end (ideally the furthest end from the QWL4.1) 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
accidental grounding. More than one ground on the network wiring can result in communication failure.
A maximum of two terminating resistors can be used.

Troubleshooting
The LEDs in the QWL4.1 ’s indicator panel on the front of the unit can be used to aid in troubleshooting and allow the
occupant to view the current operating status of the QWL4.1 .
Front indicator panel
Power LED Does Not Light Up
Be sure that the power supply module, included with the QWL4.1 , is plugged in to an outlet that has power. This is a 12V,
7A, tip positive power supply. If the power supply is plugged in to a live outlet and there is still no power, press the Reset
button located on the front panel until the CPU light is out to turn off the unit, and then press the Reset button once and
let go to restart the unit.
No Communications with Controllers on the Network
Make sure the baud rate selection for the QWL4.1 is set to match the baud rate of all the controllers on each port network
(the default communication speed of the serial bus is 9600). All controllers on the network must have a unique address,
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. Make sure the A wire goes to the A terminal in all devices, as
well as the wires that go to B and REF terminals.
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 illuminated.
For example, a solid green LED at the RJ-45 LAN connector usually indicates that the QWL4.1 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 QWL4.1 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 QWL4.1 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 QWL4.1 allow the building occupant to view operational status of the
serial communication integrated board:

Installation
• GREEN: Blinking indicates transmitting (Tx)
• YELLOW: Blinking indicates receiving (Rx)
Additionally, a single red LED (indicating the serial ports are operational) is located inside the enclosure on the Ubiquity
Cloud board.
If none of these lights are functioning, Ubiquity Cloud is not coming online. This could be because the network
communication is not set properly or there is a bad rewall proxy setting. There also 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.

Gateway Configuration
IMPORTANT: The Gateway Configuration section is for customers who did not
order their QWL4.1 preconfigured by TCS, or who need to reconfigure their unit.
If you ordered your QWL4.1 preconfigured by TCS, which is typical, you can skip this
section and jump to Lighting/Pulse Meter Programming on page 24!
Introduction to Gateway Conguration
The QWL4.1 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 QWL4.1’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 29) 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 QWL4.1 until the Ubiquity Cloud Server performs a

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 QWL4.1 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 QWL4.1 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.

Gateway Configuration
Communication Information
This section contains settings which control how the QWL4.1 connects through the Internet. All of these settings are
determined by your local network administrator or IT department.
Communication options
Communication Options
The QWL4.1 supports both static IP and Dynamic Host Conguration Protocol (DHCP) IP address allocations. Enter the
Ubiquity Cloud Server location (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 addressing or static IP addressing). When using static IP addressing, it is
necessary to enter the IP Address, Gateway, Subnet, DNS1 and DNS2 settings; these settings are 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.
MTU Adjustments
Adjusting the MTU down may allow gateways to communicate with smaller TCP packet sizes. This may be useful if you
are using cell modems not capable of passing a TCP packet with a size of 1500.
Proxy
If a proxy is required, select Static Proxy from the drop-down menu and enter all the related details in the elds that
appear. When you are nished entering information in this section, click the Update Communication Info button.
Security Information
This section contains settings which control the security of the device within the QWL4.1 and whether it can be accessed
through the web interface.
If Secure Mode has been enabled and you need access, call TCS Technical Support (800.288.9383, ext. 2) for assistance.
Here is where you change the default login credentials used to access the Conguration Page. TCS recommends
changing these credentials. Once you are nished entering information in this section, click the Update Security Info
button.
• Lockdown Mode: (Default Unchecked) When the option is checked it will disable all remote interfaces
• Secure Mode: (Default Unchecked) When the option is checked it will disable the Web UI
• Password: (Default NA) Password Change for admin account
