Each Model 1080A Series SRM has three sets of eight switches, yielding
24 total DIP switches. The three sets will be referred to as S1, S2 and
S3. As Figure 2 shows, the orientation of all DIP switches is the same
with respect to “ON” and “OFF” positions.

3.2 CONFIGURATION SWITCH SET “S1”
The DIP switches on S1 set data rate, clock source, async./sync. mode
and carrier control method. The default settings are summarized in
Table 1.
