Switches #1 and #2
Speed Switches
(Synchronous Mode)
DIP-Switches #1 and #2 are used to set the synchronous data rate.
Switches #1 and #2 are used in combination, to select the desired
speed in your application. Note that first the asynchronous/
synchronous option must be chosen via DIP-Switch #5.
9600 bps Operation = Switch #1 DN and Switch #2 DN
9200 bps Operation = Switch #1 UP and Switch #2 DN
56000 bps Operation = Switch #1 DN and Switch #2 UP
64000 bps Operation = Switch #1 UP and Switch #2 UP
(Factory Default Setting = Switch #1 DN and Switch #2 UP)
Switches #1 and #2
Speed Switches
(Asynchronous Mode)
DIP-Switches #1 and #2 are used to set the asynchronous data rate.
Switches #1 and #2 are used in combination, to select the desired
speed applications. Note that first the asynchronous/synchronous
option must be chosen via DIP-Switch #5.
9600 bps Operation = Switch #1 DN and Switch #2 DN
19200 bps Operation = Switch #1 UP and Switch #2 DN
38400 bps Operation = Switch #1 DN and Switch #2 UP
57600 bps Operation = Switch #1 UP and Switch #2 UP
(No Factory Default Setting = User Selectable)
Switches #3 and #4
Internal/External/DDS Clocking
(Asynchronous/Synchronous Mode)
DIP-Switches #3 and #4 are used in combination to select clocking
(timing for synchronization) from one of three sources--Internal,
External or DDS Clocking.
Internal clocking
enables the MultiDSU64K to accept timing from its
internal timing oscillator.
External clocking
allows the MultiDSU64K to derive timing from any
external device that can supply timing to the External Transmit Clock
line on the MultiDSU64K’s interface connector. This external clock
must be within 0.008% of the nominal data rate.
