Black Box ME759C-RJ11, May-95 S1 Positions 1 through 4 Data-Rate Setting, S1 Position 7 Protocol

MULTI-FUNCTION LD CARD

S1 Positions 1 through 4: Data-Rate Setting

Set positions 1 through 4 of switch S1 to determine the data rate (valid for both synchronous and asynchronous protocols) of the Multi-Function LD Card.

S1-1	S1-2	S1-3	S1-4	Data Rate
On	On	On	On	1.2 kbps
Off	On	On	On	1.8 kbps
On	Off	On	On	2.4 kbps
Off	Off	On	On	3.6 kbps
On	On	Off	On	4.8 kbps
Off	On	Off	On	7.2 kbps
On	Off	Off	On	9.6 kbps (default)
Off	Off	Off	On	14.4 kbps
On	On	On	Off	19.2 kbps
Off	On	On	Off	28.8 kbps
On	On	Off	Off	38.4 kbps
Off	On	Off	Off	57.6 kbps

S1 Positions 5 and 6: Clock Source

Set positions 5 and 6 of switch S1 to determine which transmit-clock source the Multi-Function LD Card uses.

S1-5	S1-6	Clock Source
On	On	Internal transmit clock (default)
Off	On	Receive-recover clock
On	Off	External transmit clock

S1 Position 7: Protocol

Set position 7 of switch S1 to determine whether the Multi-Function LD Card operates synchronously or asynchronously.

S1-7	Protocol
On	Asynchronous (default)
Off	Synchronous
