Technically Speaking
✦ The control sequence of the Code Operated Switch II is a pair
of ASCII characters: one “arming character” that gets the box’s
attention and prepares it to switch, and one “port-selection
character” that identifies the port to switch to. You can select
any of the 256 characters in the extended ASCII character set
to be the arming character.
✦ Graphics data can include almost any combination of
characters, including those of the COS II’s control sequences.
For this reason, the COS II has a “graphics pause” feature
that allows it to handle graphics files without unintentional
switching: A pause (an absence of data) whose length you
can set must occur before the COS II will recognize a pair of
characters as a control sequence; otherwise, the COS II will
pass the characters as data.
✦ You can also choose whether the COS II passes the hardware
flow-control leads DTR and CTS through to the attached
devices, or uses them strictly to control its buffer.
You may also need:
✦ A snap-in 4-Port Expansion Board for controlling four additional
slave devices. You can install this circuit board in only minutes
with just a screwdriver.
✦ An asynchronous RS-232 modem or line driver
for long-distance control of your devices.
✦ RS-232 cable.
✦ AC and data-line surge protectors.
✦ A country-specific power cord or adapter for operating
the COS II outside of North America.
✦ Communications software.
