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.

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.
