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)
