CHAPTER 3: Configuration
3.3 Choosing the Arming Code
Use the DIP switch labeled SW12 inside the High-Speed COS-4 or COS-8
to set the COS’s “arming code” (the character that alerts the COS 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). For first-time
configuration, leave the case open to set your ports for DTE or DCE (see
the next section).
3.4 Setting Ports as DTE or DCE
Decide which devices you’re going to connect to which of the High Speed
COS-4’s or COS-8’s ports. Then set the DTE/DCE slide switches inside the
unit (there’s one just behind every port) so that you can use standard,
straight-through-pinned cables to attach the devices to the ports: If a device
is a DTE, set the port as DCE (move the switch to the B position); if a device
is a DCE, set the port as DTE (move the switch to the A position). Once
you’ve finished, replace the COS’s cover and secure it by screwing the
screws back in.
