Parallel Printer Extenders
under Parallel Printer Extenders|
The parallel interface has a serious limitation in that data can only be transmitted reliably over relatively short distances. This problem is solved with the lightweight, easy to use ADP3230. The speed of the ADP3230 outperforms any available product of its kind, and use of 4 wire telephone line virtually guarantees error free transmission.
This is the DB25M to CN36M version for printers; the ADP3231 is a DB25M to DB25M version for switchboxes.
This extender can usually get its power through the signals in the ports, however, it occasionally would need an external power source. For this an ADD090305 can be connected to the Printer end.
