Configuration Switch Set "S1" - Patton electronics 1140RC User Manual

3.1.1 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. Following the table is a description of all possible S-
1 switch settings.

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 1140RC.
S1-5 S1-6 Setting
On On Internal transmit clock
Off On Receive recover clock
On Off External transmit clock
S1-7: Asynchronous/Synchronous Mode
The setting for switch S1-7 determines whether the Model 1140RC
is in asynchronous or synchronous operating mode.
S1-7 Setting
On Asynchronous
Off Synchronous
S1-8: Carrier Control Method
The setting for switch S1-8 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 Setting
Off Constantly On
On Switched Carrier
