The Black Box TL159A is a hardware module designed to broadcast RS232 serial data across an RJ-11 interface, supporting up to eight ports. This device is engineered for scenarios where a single RS232 data stream needs to be distributed to multiple endpoints simultaneously. Its TAA and GSA compliance makes it suitable for government and enterprise deployments requiring adherence to specific procurement standards. Use this device when you need to replicate serial commands or data to multiple devices from a single source, such as distributing control signals to multiple access control readers or point-of-sale terminals.
This device is designed to receive a standard RS232 serial data input and broadcast it over its eight RJ-11 outputs. It is compatible with any system that outputs standard RS232 serial data, including various industrial controllers, security system components, and legacy equipment. The RJ-11 interface is a common connector for serial data distribution in specific applications, ensuring broad compatibility with compatible peripherals and systems.
Installation involves connecting the primary RS232 data source to the device's input port and then connecting the desired endpoints to the eight RJ-11 output ports using standard RJ-11 cabling. Ensure that the RS232 data source is configured to broadcast or multicast its data stream. The device operates passively, replicating the input signal to all outputs without requiring external power, simplifying deployment in environments where power outlets are scarce.
