Send serial data to up to eight printers or terminals at once. Or send parallel data to two printers simultaneously.

Key Features

Key Features Data Broadcast Units: Fully regenerate an async host signal and broadcast it out to eight slave ports. Choose from DB25 or RJ-11 versions.

 Buffered Data Broadcast Units: Buffered Data Broadcast Units:

Port buffering lets your connected devices receive data continu- ously, regardless of their speeds.

Parallel Data Broad- cast/Fallback Unit: Sends parallel data to two printers at once, or “falls back” for continuous data output.

If you want to transmit data to more than one printer or terminal at the same time, choose among our Data Broadcast Units, Buffered Data Broadcast Units, and Parallel Data Broadcast/ Fallback Unit. These solutions get the job done—without losing signal strength!

Data Broadcast Units

The Data Broadcast Units enable you to transmit data from any serial async device to up to eight printers, modems, or terminals simultaneously.

The Data Broadcast Units take the RS-232 signal from your async host, divide it among eight slave

ports, and then completely regen- erate and broadcast each of those new port signals to their respective devices.

There’s a model for DB25 cabling and one for RJ-11 cabling to fit your needs. The DB25 model is available in 115- or 230-VAC versions.

Buffered Data Broadcast Units

The Buffered Data Broadcast Units function in the same way as the Data Broadcast Units, but they also feature individually buffered ports. These let you send async data to devices operating at

various speeds. You can config- ure each port for word structure, baud rate, flow control, and DTE or DCE operation.

Versions are available for 115- or 230-VAC power.

Parallel Data Broadcast/

Fallback Unit

This unit lets you send parallel data to two printers simultaneous- ly, or designate a backup printer in case your primary printer fails.
