The AF-142 is a Bi-tronics Auto Switch that will operate in either, one computer to two printers mode, or two
computers to one printer mode, called respectively 1 to 2 mode and 2 to 1 mode. The AF-241 Bi-tronics Auto
Switch is only capable of operating only in 2 to 1 mode. These switches operate in 2 to 1 mode without software
drivers and deliver print jobs to the printer on a first come, first served basis. This means that if one computer is
printing to the printer the other computer must wait for the Auto Switch to finish the current print job. The AF142, when operating in 1 to 2 mode, uses the AS Ware driver to select which printer of the two attached to the
Auto Switch will print the print job. You can only be printing to one printer at a time unless both printers are
identical and you wish to rapidly produce many copies of the same document. The AF-142 can go into a unique
“broadcast” mode and both printers will print the exact same document, leaving you with two copies.

Turn the power to all devices to be attached to the Auto Switch.
Connect the Bi-tronics Auto Switch to your computer by using a straight through DB-25 male to male
cable.
Connect the Bi-tronics Auto Switch to the parallel devices by cables with one DB-25 to C-36 male to male
cable. (See Figure 1)
Set the DIP Switch (located on the top of the auto-switch) to 2 → 1 mode with a time out of either 15 or 45
seconds, by setting DIP switches #3 and #4 appropriately (NOTE: The AF-241 does not support 1 → 2
mode.)
Turn on your computers and the printer. The four LED’s should flash alternately as the Auto Switch scans
for print jobs.
A power adapter is required when the Bi-tronics Auto Switch can not get enough power from the devices
that are attached to it and functions Intermittently.

2 to 1 mode (for AF-241 and AF-142)
Auto mode:
In Auto mode the Bi-tronics Auto Switch automatically scans all the input ports for print jobs, it shows
that it is in Auto mode by flashing the LEDs of the ports in an alternating patern. When the Auto
Switch detects a print job on any input port it will stop searching for print jobs and “lock” the active
input port so that no other print jobs can be printed until the first job is finished. This is known as
First-Come, First-Served. After the print job completes the Auto Switch will release the input port and
return to automatically scanning the input ports for incoming print jobs.
Manual mode:
In Manual mode the Bi-tronics Auto Switch allows only one computer to print. When the manual
button is pressed the port scanned for an incoming print job moves from one port to the next as the
button is pushed. When the port is selected manually that port is the ONLY port that can print. The
Port Status LED will light for the currently active port as shown in the following example:
Port A is selected (LED A is illuminated)
Port B is selected (LED B is illuminated)
Auto mode is selected (LED A lights, then LED B, and back again)
The button on the side of the Auto Switch has no effect either while the printer is printing nor during
the timeout period. This is a safety feature to prevent potential data loss.
File Transfer Mode:
When you are using the AF-241 or the AF-142 in 2 to 1 mode you are able to activate the File transfer
mode of these devices. You select file transfer mode by pressing the button on top of the unit until
both LED’s are constantly on. By activating the file transfer mode you will be able to not only
share files, but peripherals as well. However, you will need some additional software assistance such
as Interlnk/Intersrv of DOS, or FastLynx of Rupp Corp. In Windows 95 you may also use the
Direct Cable Connection in the networking options. However, this requires that have Direct Cable
Connection installed,also you must install the IPX/SPX network protocol, file and print sharing must
be enabled, and at least one folder must be shared.
1 to 2 mode (for AF-142 ONLY!)
With the AF-142 in 1 to 2 mode you can select what printer you wish to print to, Or if all the printers attached
to the Auto Switch are identical you can print to all of them at the same time. To tell which port is selected
check for the lighted LED. When a port is selected the corresponding LED will illuminate and, if you are in
broadcast mode all the LED’s will illuminate to show that the print job is going to all connected printers.
Selecting the printer manually:
The selected port (when using the manual controls) will shift to the next higher port each time you
press the button. For example if you are currently on PORT A, pushing the button will shift you to
PORT B, If you are on PORT B pressing the button will take you to PORT D. Below is the order in
which the ports are selected by using the button. (NOTE: If your Auto Switch is not on PORT A when
you start, the cycle will begin with your current port and continue along the pattern)
PORT A → PORT B → Broadcast Mode → (Back to) PORT A
Selecting the printer through software controls:
If you are operating is a DOS environment you can use the Hot Key commands to change the printer
port that you are printing to. In a Windows environment you will use the AS Ware Icon to select
which port you will be printing from.
NOTE: The Hot Keys ONLY function in DOS. They do not work in Windows.
About the Software
The software allows you to directly select any PORT, or select all PORTS at once in broadcast mode.
This software ONLY needs to be installed when you are using the AF-142 in 1 to 2 mode. The AF241 and the AF-142 in 2 to 1 mode do not require any software drivers as they are fully automatic. For
additional information on this software please view the READ.ME file included on the driver diskette.

IMPORTANT: Before beginning any of the following troubleshooting proceedures please check for properly
connected cables, if the cables appear to be connected correctly then remove the Auto Switch from the system
and connect the printer directly to the computer with both cables if possible (one cable at a time).
LED locks on the PORT when a cable is connected:
• The Bi-tronics Auto Switch may receive some errant signals that begin a “timeout” count. If the
connected printer is ready, just wait until the “timeout” counter returns to zero. (This will be either
15 or 45 seconds from the “timeout” begins)
• Set DIP Switch #1to the ON (Reset) Position to reset the Auto Switch and then try again.
• If the Printer attached to the PORT is one of many Hewlett Packard or it is one of the EPSON
Stylus 400, 600, or 800 series you may have to take extreme measures in order to disable the
aggressive status checking nature of these printers.
1. In Windows 95 push the Start button, select settings, select printers.
2. Find the correct printer Icon and double left-click on the Icon.
3. Activate the Printer pull-down menu and select Properties.
4. Across the top of the Printer Properties window there are several tabs select the
Details tab.
5. Towards the bottom of the Details window are two buttons Spool Settings and Port
Settings.
6. First select the Spool Settings button then check the lower third of the new window
for a selection “enable bi-directional support for this printer” make sure that this
selection is NOT checked and the selection “disable bi-directional support for this
printer” IS checked. Then press OK.
7. Now select the Port Settings button. You are now looking for a box labeled “Check
Port Status before printing” Make sure that this box is NOT checked, then click
OK.
The Printer status window shows “Printer not Responding” or “Cable not Connected” intermittently.
• Make sure that only one printer with a status monitor (bi-directional) attached to it is installed in
your system. If you have more than one printer status monitor installed at one time the printer
drivers for those printers will “fight” for control of the LPT port causing error messages to appear
in either one or the other of the status monitors.
(For additional information on removing status monitor programs from your system please go
to our web site http://www.aten-usa.com/faq/autoswitch.htm)

•
Use the manual selection button to “Lock” onto a specific printer before installing the driver, or
remove the Auto Switch during the installation of the Printer driver. (Be sure to directly attach the
printer to the Computer during the installation process)
After you install the new print drivers you should restart windows so that the Auto Switch can
properly emulate the new bi-directional printers responses.
Status window can not display printer status properly.
•
Change your computers LPT port type to either standard or EPP and try installing the drivers again.
