3.1.1 CONFIGURATION SWITCH SET “S1”
The eight DIP switches on pack S1 set data rate, clock source,
async/sync mode and carrier control method. Factory default settings
are summarized in Figure in the table below. Descriptions of all
possible S1 switch settings, including the Patton factory default
settings, are found on on pages 4 and 5.
S1-1 through S1-4: Data Rate Setting
Switches S1-1 through S1-4 are set in combination to determine
the asynchronous and synchronous data rate for the Model 1045RC.

S1-7: Carrier Control Method
5
The setting for switch S1-7 determines whether the carrier is
“constantly on” or “controlled by RTS”. This setting allows for operation
in switched carrier, multipoint and/or hardware handshaking
applications.

S1-8: V.52 and V.54 Diagnostic Test
To reset the V.54 circuit, set switch S1-8 to the “ON” position, then
back to the “OFF” position.

3.1.2 CONFIGURATION SWITCH SET “S2”
The eight DIP switches on pack S2 set RTS/CTS delay, word
length, extended signaling rate, async/sync mode and remote test
initiation. Factory default settings are summarized in the table below.
Descriptions of all possible S1 switch settings, including the Patton
factory default settings, are found on on pages 6 and 7.
