HIGH SPEED COS-2
Before you install the High Speed COS-2, you should configure it for your
application.
Section 3.1
describes setting the front-panel Mode switch to
select your desired operating mode.
Section 3.2
describes setting the right-
hand DIP switch so that the COS-2 operates using the communication
parameters that you need;
Section 3.3
describes how to choose your arming
code by setting the left-hand DIP switch. For each of these sections, refer to
Figure 3-1 on the next page for the locations of the switches being discussed.
3.1 Selecting the Operating Mode
Use the slide switch labeled “Mode” on the front of the High-Speed COS-2
to select which operating mode you want the unit to start in. In the left-
hand position, the Text mode is selected (neither MODE LED is lit); in the
center position, the Graphics mode is selected (the left-hand MODE LED is
lit); in the right-hand position, the Transparent mode is selected (the right-
hand MODE LED is lit). (See
Chapter 2
and
Section 5.2
for descriptions of
these modes.)
3.2 Setting Communication Parameters
Use the right-hand DIP switch on the bottom of the High-Speed COS-2 to set
the COS-2’s communication parameters. As shown in Table 3-1 on page 12,
positions 1 through 3 control the data rate; positions 4 and 5 control the
data format; and positions 7 and 8 control the graphics-mode pause. (Use
position 6 during operation when you want the COS-2 to run its self-test.)
3.3 Choosing the Arming Code
Use the left-hand DIP switch on the bottom of the High-Speed COS-2 to set
the COS-2’s “arming code” (the character that alerts the COS-2 to an
impending switch). As shown in Table 3-2 on pages 13 through 19, each
possible setting of the eight DIP switch positions corresponds to a one-byte
character value from 00 to FF hex (0 to 255 decimal).
