Black Box Passive Modem Splitter TL073A-R4

The Black Box Passive Modem Splitter TL073A-R4 is a versatile solution designed to connect three terminals to a single modem, effectively reducing the need for multiple modems and additional phone lines. This device enables seamless sharing of one RS232 DCE device with up to three RS232 DTE devices.

Key Features

• Efficient Signal Distribution: The MASTER port is configured as DTE, while PORTS 1–3 are configured as DCE. Signals present on the MASTER connector at pins 1, 3, 5, 6, 7, 8, 15, and 17 are transmitted to the corresponding pins on each of the PORT connectors. Conversely, signals on the PORT connectors at pins 2, 4, and 20 are passively stored and sent to the corresponding pins on the MASTER connector.
• Transparent Operation: The modem splitter operates transparently to speed and protocol, functioning effectively in both synchronous and asynchronous environments.
• Simple Installation: No special cables are required for setup. The device utilizes standard straight-pinned cables and includes a 6-foot DB25 male to DB25 female extension cable, along with a serial DB9 female to DB25 male AT adapter, facilitating straightforward installation.
• Data Transmission: Data entering the MASTER port on pin 3 is distributed to all three slave ports, as they are all tied common. However, only one slave port may transmit data to the MASTER port at any given time, ensuring organized communication.
