The 3010-401 series RS232 auto switch
provides an easy method of sharing one
printer or other RS232 device with up
to four computers.
It is fully transparent, meaning that
the user will usually not even be aware
that it is in place.
It requires no special software,
and no manual switching.
It features "first come, first serve"
switching and timeout controlled by
DTR or TXD. The switch continuously
polls each input port until it detects
activity on a port, at which time
the switch "locks on" to that port
and maintains an open channel until all
printing activity is done, and the timeout
period has expired. At that time it
resumes polling input ports.
It has 4 DCE type input ports and 1 DTE type output port.
The input connectors on the switch are DB25F (DCE type).
The output connector on the switch is DB25M (DTE type).
