The Model 1065 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 the table below.
Switches S1-1 through S1-4 & S3-3: Data Rate Setting
Switches S1-1, S1-4, and S3-3 are set in combination to deter-
mine the asynchronous and synchronous data rate for the Model 1065.
Shown in the tables below are DIP Switch settings for Models
1065.

Switches S1-5 and S1-6: Clock Source
Switches S1-5 and S1-6 are set in combination to determine the
transmit clock source for the Model 1065 Series.
