2.3 SWITCH SET SW1
The DIP switches on SW1 set data rate, clock source, async./sync. mode and carrier
control method. The default settings are summarized in the table below.
SW1 through SW-4: Data Rate Setting
Switches SW1-1 through SW1-4 are set in combination to determine the asynchro-
nous and synchronous data rate for the ME670A.
