Extron BUC 202 Bidirectional RS-232 and IR Converter
The Extron BUC 202 is a compact bidirectional converter that translates RS-232 signals to IR control signals and vice versa, enabling seamless integration between RS-232 controlled devices and IR-controllable equipment in professional AV systems. It features a 3.5 mm captive screw connector for RS-232 (Tx/Rx/Gnd) on one side and a 3.5 mm stereo mini jack for IR output/input on the other, supporting bidirectional IR pass-through for two-way IR devices or unidirectional IR blasting. This makes it ideal for extending control in classrooms, conference rooms, boardrooms, auditoriums, and control centers where an RS-232 controller needs to command IR-based devices like projectors, displays, DVD players, or cameras, or where IR commands need to be converted to RS-232 for automation.
The converter operates passively with no external power required when used in typical unidirectional setups, though it draws minimal power from the RS-232 port when bidirectional IR is active. Its small form factor allows easy mounting behind equipment or in tight spaces, while the captive screw connector ensures secure, vibration-resistant RS-232 termination in permanent installations.

FAQ
- What is the main purpose of the BUC 202? It converts RS-232 control signals to IR commands and vice versa, allowing RS-232 controllers to operate IR devices or IR feedback to reach RS-232 systems.
- Does it support bidirectional IR? Yes, it supports bidirectional IR pass-through for devices that provide IR feedback, in addition to standard unidirectional IR blasting.
- Is external power required? No, it operates passively for unidirectional RS-232 to IR conversion; minimal power may be drawn from the RS-232 port in bidirectional setups.
- What connectors are used? RS-232 uses a 3.5 mm captive screw connector (Tx, Rx, Gnd), and IR uses a standard 3.5 mm stereo mini jack for emitters or receivers.
- Can it be used with Extron controllers? Yes, it is optimized for use with Extron control systems that output RS-232 or require IR control bridging.
- What IR frequencies are supported? It handles common IR carrier frequencies from 30 kHz to 60 kHz for compatibility with most AV devices.
