Digital Telegraph Adapter CTA-0124 for Connecting PCs to Telegraph Lines

Designed for use as a device for interfacing PCs with telegraphic communication lines via RS-232 or USB interfaces.
The CTA provides:
- possibility to connect up to two telegraph communication lines (junction C1-TG);
- simultaneous independent exchange of information over the connected communication lines;
- restoration of distorted received signals;
- galvanic isolation of receiver and transmitter circuits;
- overvoltage protection of the receiver and transmitter input circuits;
- automatic indication of reception and transmission of information, emergency situations: open circuit, short circuit, counter switching.
For each of the connected telegraph lines is allocated its own RS-232 or USB port.
