Black Box RS232 Passive Splitter Rackmount Card – 4-Port RJ45 for RS-232 Terminals

Black Box RS232 Passive Splitter Rackmount Card - RJ45, 4-Port

The Black Box RS232 Passive Splitter Rackmount Card (Part Number TL421-C) offers an efficient solution for connecting up to four RS-232 terminal devices to a single modem. Designed for use with the RS-232 Modem Splitter Rackmount Chassis - 2U (TL400A), this 4-port splitter simplifies the process of sharing a modem among multiple terminals, reducing the need for multiple modems and lines. Its passive, non-powered design ensures seamless operation without additional power sources, making it a cost-effective and reliable choice for various communication setups. The splitter connects to your modem via an RJ-45 straight-through cable, while each terminal device connects to one of the four ports, enabling straightforward integration into existing systems. The device's logical OR gating ensures that data from the terminal devices is correctly transmitted to the modem, maintaining data integrity and protocol transparency. It supports all data formats, speeds, and protocols, allowing flexibility across different applications. Only one terminal can send data at a time, preventing data collisions and ensuring smooth communication. The splitter also transmits data received from the modem to all connected terminal devices, facilitating efficient data sharing. Built in the United States by Black Box Corporation, this product is TAA compliant and comes with a one-year limited warranty. Its lightweight design makes installation and handling simple, providing a durable and environmentally friendly solution for industrial and office environments.
