The decode of configuration switch functions is indicated in Figure 5 and discussed in detail
in the paragraphs that follow.

This configuration switch configures the translator with respect to the following functions:

1.

BNC Input Group (allocated in x8 groupings) and protocol “flavor” (15 or 32 bit Coax-
itron)

2.

Choice of P or D protocol.

3.

Communications channel baud rate (under P protocol only).

4.

Cascade addressing (16/32 channel or translator address range)

5.

Type of 32-bit protocol (Intercept or Spectra).

Figure 5.  Configuration Switch

 Configuration switch positions are read only at power-up time; therefore,

switch changes made after power is applied have no effect until power is recycled.

The sixteen BNCs to which Coaxitron receivers are attached are split into x8 groups (1-8
and 9-16). Each group is further defined as entertaining one of two protocol “flavors”: 15- or
32-bit (these are references to 15-bit standard Coaxitron or 32-bit extended Coaxitron, re-
spectively). Therefore, a combination of 15- and 32-bit protocol “flavors” on the same unit is
possible. Conversely, if both x8 groups on the same translator are assigned the same proto-
col flavor, then the entire translator interfaces only 15-bit or only 32-bit Coaxitron receivers.

Figure 6.  BNC Input Group and Protocol “Flavor”

 If any x8

group combination is set to
32-bit, DIP switch 1-8 must
be set to restrict equipment
use for the entire translator
to ONLY one equipment
type (receiver): Intercept or
Spectra.
