4 to 1 mode (for AS-8441B and AS-8144B)
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)
Port D is selected (LED D is illuminated)
Port E is selected (LED E is illuminated)
Auto mode is selected (LED A lights, then LED B, then LED D, then LED E, 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.
