Black Box VX-1001-TX-R2 RS-232 Extender
Overview
The Black Box VX-1001-TX-R2 is a serial data extender designed to transmit RS-232 control signals over standard Cat5e/6 cabling. This device is critical for extending the reach of control commands beyond the typical 50-foot limitation of RS-232, enabling remote management of AV equipment, surveillance cameras, or other serial-controlled devices in large facilities or complex installations. Its compact form factor and reliance on common network cabling make it a practical solution for integrating control into existing infrastructure.
Compatibility
This extender is designed to work with any device utilizing the RS-232 serial communication protocol. It is commonly deployed with Black Box Extend AV extenders and switchers, as well as third-party AV control systems, matrix switchers, and PTZ cameras that require serial command input for functions such as power control, source selection, or camera positioning. The VX-1001-TX-R2 operates as a point-to-point solution, requiring a matching receiver unit (sold separately) at the remote end.
Installation Notes
Installation requires two VX-1001-TX-R2 units (one transmitter, one receiver) connected via a single Cat5e or Cat6 cable, not exceeding 1000 feet (305 meters). Each unit requires a 5VDC power supply (sold separately). Ensure proper termination of the RS-232 connections on both the source and destination devices to avoid communication errors. The use of shielded twisted-pair (STP) cabling is recommended in environments with high electromagnetic interference to maintain signal integrity.
