Switches S1-6 and S1-7: System Clock Mode

Use Switches S1-6 and S1-7 to configure the 1082/I or Model 1082/144/ I for internal, or receive recover clock mode.

S1-6	S1-7	Clock Mode	Description
On	On	Internal	System clock generated internally
On	Off	Receive Recover	System clock derived from the
			received line signal
Off	Off	Hardware Reset

	A pair of Model 1082/Is communicate synchronously
	across the twisted pair line connection. Therefore, you
	must set these switches whether your application is
	async or sync. For Sync or Async applications, please
	configure one Model 1082/I for internal clock mode and
	the other Model 1082/I for receive recover clock mode.
