The Telebyte 72A Optically Isolated Line Driver links RS-232 based devices over extended distances. It provides optical isolation and has built-in verification of operation using a loopback switch. The 72A communicates via 4-wire cable with another 72A, 72 or the rack mounted Model 75.

 

The Telebyte Line Driver 72A is designed for asynchronous operation over two twisted pair, non-loaded, metallic (DC continuity) cable up to 19.2 KBPS. Each modem is equipped with Transmit Data and Receive Data LED's to simplify installation and troubleshooting. Verification of modem operation is simplified using the built-in loopback switch. A second switch reverses pins 2 and 3 of the RS-232 connector for interfacing with either DCE or DTE devices. The Telebyte Line Driver 72A is available with male or female DB25 connectors. The 4-wire line termination includes 4 screw terminals and a modular phone jack.
