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.

Centronics 2 Computer Adapter, Model 25210
The 25210 Adapter allows two PC‘s to be connected to a single
printer over a parallel interface.
The Adapter input provides 36-pin Centronics females so that
the original printer cables can still be used.
A printer cable for connecting the printer to the Adapter is
included.

EPP/ECP/Bitronics 2 Computer Adapter, Model 25215
The 25215 Adapter allows two PC‘s to be connected to a single
printer over a bidirectional parallel interface.
The Adapter input provides 36-pin Centronics females so that
the original printer cables can still be used.
A printer cable for connecting the printer to the Adapter is
included.
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).
Important: In some cases manufacturer-specific Windows
printer drivers communicate continuously and permanently
with the connected printer. This trait must be restricted to the
time of the actual print-out and can generally be set in the
driver software. Continuous communication between the driver
software and printer always locks out the corresponding input
of the converter and makes the printer inaccessible for the
second computer. If access to the printer from this PC is only
possible if you exit Windows on the first computer, this is a
clear indication of such a problem.

2 / 4 Computer Adapter
If another print job is started parallel to a running print job on
the second connected computer, a Windows-generated error
message is generally displayed immediately to indicate that the
connected printer is not available. The driver attempts to
establish contact with the printer without delay but of course
fails, since the printer is at this moment already used by
another computer. If the driver wait time until an error message
is generated cannot be set, the user must wait to start the print
job until the previous job has finished. If both problems cannot
be resolved by configuring the printer driver, you can generally
solve the problem by installing an equivalent, non-bi-directional
standard 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
