The Transfer Trip module will accept address settings from 0 to 63, however there are
certain exceptions depending on the Actel version used as described in the Table 5.
Table 5. Actel version vs. allowed addresses
Actel Version Allowed Addresses
Actel Version 5 or
higher on both sides
or
Actel Version 4 or lower
on both sides
0-7, 16-23
32-39, 48-55
Actel Version 5 or
higher on one side
and
Actel Version 4 or lower
on the other side
Use addresses in tables
6 & 7 as applicable
(Also refer to Figures
10 and 11)
As shown in Table 5, the selection of allowed Tx and Rx addressess on the DSTT
module depends on the version of the Actel used at both sides (transmit end and receive
end).
To determine the Actel version on a DSTT module, remove the DSTT module from the
multiplexer chassis and read the software label on device U12. The last one or two digits
of the SW number indicates the Actel version. The software label will be similar to the
one shown in Figure 9.

Figures 10 and 11 for addressing examples.
