Centronics 4 Computer Adapter, Model 25410
The 25410 Adapter allows up to four PC‘s to be connected to a
single printer over a parallel interface.
The Adapter electronics are integrated in a Centronics which
can be connected directly to the printer port.
At the input the Adapter is provided with 36-pin Centronics
females, so that the original printer cables can still be used.
Function
The computers are automatically selected on a time-controlled
basis: First any computer is able to print. Whichever PC starts
to print first automatically blocks print output from the other. If
the currently printing computer pauses for approx. 10 seconds
(default setting), the procedure starts over again (who is
printing first gets access to the printer). This pause can be
adjusted to between 5 and 60 seconds using a potentiometer
inside the device. In case of a problem, please check first
whether the printer functions when it is connected directly to
the other computer (without the Adapter).
The Adapter supports only data transfer from the PC to the
printer, and not in the other direction.
If bi-directional support is needed, use the „IEEE P1284
Centronics 4 Computer Adapter, bi-directional“, Part no. 25415.
Alternately it is generally possible to achieve bi-directional
support using the printer settings for the printer driver.
