CHAPTER 2: Introduction
With the High Speed COS-2, you can send a code sequence from an
asynchronous RS-232 device and switch between two other such devices. By
using this electronic method to switch, you avoid the problems that can
occur (especially with laser printers) when you switch manually. You can
select any two-byte sequence as the “arming code” (the code that causes the
COS-2 to switch).
As you can see, the COS-2 is very light and compact. For this reason,
we’ve included a hook-and-loop fastener that you can use to attach the unit
directly to any number of surfaces, including the housings of PCs and
printers.
The COS-2 has three modes of operation, which you can choose between
with the appropriate slide switch on the front panel. In Text mode, the user
can send the chosen arming code, followed by the ASCII character
corresponding to the desired port (either “B” or “C”), immediately
following other data. In Graphics mode, the arming code and port
character are not recognized unless they are preceded by a pause. (You can
select the length of this pause.) In Transparent mode, arming codes are not
recognized and switching does not occur.
