Dawn of a new era in X10 Automation Reliability
JV Digital Engineering
The XTB-III digital port will accept the same connector that would normally be plugged into the X10 TW523 or PSC05. The XTB-III opto-isolated digital interface is functionally identical to that of the TW523, but the XTB-III TW523 emulation differs from the actual TW523 in several regards. The XTB-III error checks all incoming data, and does not produce any output when a collision is detected. And since the XTB-III does not need a gap to separate X10 messages, it will recognize all commands in a bright/dim sequence. The XTB-III will both transmit AND receive extended messages.
The XTB-III runs the same firmware as the XTB-IIR, but the repeater function is disabled by default. The repeater function can be enabled through a mode option, but that is not recommended unless all X10 transmitters are on the same phase that is connected to the Phase I input.
See the XTB-IIR Mode Options document for a detailed description of the available mode options.
The XTB-III is a 3-phase version of the XTB-IIR. This unit is intended as a high power 3-phase powerline interface, and provides TW523 emulation for high-end controllers such as the Elk M1 or the WGL V572A RF transceiver. It also includes an X10 Boost input on the cover to directly boost the output of an X10 transmitter. Since it doesn’t have three independent processing channels, its repeater function can only be used on a 3-phase system if all transmitters are confined to the same phase that is connected to its Phase I input.
The XTB-III will function perfectly as a repeater on a standard North American 120/240V split phase system, and a special version with just two coupling networks is available as the XTB-IIR+. With its even larger power supply, the XTB-II+ outputs the strongest signal of all units. A 240V 50Hz version is also available for international applications.
