The Porter™ Advantage . . .
The Porter is a very versatile, code activated switch
that allows a computer or terminal to send serial or
parallel data to a selected device. Each port (4 or 8)
can be configured to match the connected
equipment's protocol.
The Porter is easy to install and uses commonly
available cables. It works with any device with serial
or parallel ports. The serial connectors are DB25F and
the parallel connectors are Centronics 36 pin female.
The receive buffers accept data on all ports
simultaneously. This data can then be read from the
master port one at a time. The Porter transmits from
buffers on all ports simultaneously. The “clear buffer”
command purges all data in a port’s buffer. The
broadcast feature allows you to send data
simultaneously on all ports. The Porter’s buffer is
expandable to 256K bytes.
These are a few of the features that make the Porter
one of the best code activated switches on the
market. Call us today about your code-activated
switch application.
