Remote Technologies Inc. (RTI) has designed the T1-B, which will be available in June, with 40 assignable keypad buttons that can be individually programmed to control devices or execute multi-step macros for more complex installations involving several components. For intuitive control, the unit offers eight source and four general purpose keypad buttons with interchangeable key labels. When other RTI devices are used, the T1-B is capable of RF transmission through walls and cabinets, RS-232 control, contact closures, and power sensing.
