Black Box TL400A RS232 Passive Splitter Rackmount Chassis
Overview
The Black Box TL400A is a 2U rackmount chassis designed to house and distribute RS-232 serial data signals. This unit is essential for deployments where a single RS-232 source needs to communicate with multiple serial devices simultaneously, such as connecting a central control system to several peripheral devices in a rack. The TL400A provides a clean, organized, and reliable method for managing serial connections in a professional AV or IT environment, ensuring signal integrity across all output ports.
Compatibility
This chassis is specifically designed for use with Black Box RS-232 passive splitter modules. It is intended for rack-based installations and is compatible with standard 19-inch equipment racks. The chassis itself does not contain active electronics but serves as a passive distribution hub for compatible splitter modules.
Installation Notes
The TL400A chassis requires the installation of individual Black Box RS-232 passive splitter modules (sold separately) into its available slots. Ensure that the modules are correctly seated and secured. The chassis occupies 2U of vertical space in a standard equipment rack. Connections are made via standard DB9 connectors on the rear panel for the input and output ports, depending on the installed splitter modules.
