PC 2 Computer Adapter, Model 15210
The 15210 Adapter allows two PC‘s to be connected to a single
printer over a parallel interface.
The Adapter electronics are integrated in a somewhat larger
Centronics plug which can be connected directly to the printer
port.
The connection cables required are already hard wired to the
Adapter.
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 (whoever 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 2 Computer Adapter, bi-directional“, Part no. 25215.
Alternately it is generally possible to achieve bi-directional
support using the printer settings for the printer driver.

Supply voltage
The Adapter is designed using power-saving CMOS technology
and can generally be powered with no problem by the signal
lines of the parallel interface.
Optionally it is possible to power the Adapter via an external
power supply having an output voltage or 5V regulated. Such a
power supply can be ordered from W&T under Part no. 11050.
