3.1.1 Configuration DIP Switch Set “S1”

Use the eight switches in DIP Switch Set “S1” to configure the data rate, asynchronous or synchronous data format, transmit clock source and response to RDL request. The following table summarizes default positions of DIP Switch S1. Detailed descriptions of each switch follow the table.

S1 SUMMARY TABLE

Position	Function	Factory Default
S1-1	Data Rate	On	}	64K Sync
S1-2	Data Rate	Off
S1-3	DSR during Local Line Loop	On		DSR On
S1-4	SNMP Management	Off VT100 Mgmt
S1-5	Reserved	Off
S1-6	Tx Clock Source	On	}	Internal Clock
S1-7	Tx Clock Source	On
S1-8	Response to RDL Request	On		Enable

Switches S1-1 and S1-2: Data Rate

Use Switches S1-1 and S1-2 with Switch S2-1to configure the Async or Sync bit rate for Model 1092A. The following table summarizes default positions of DIP Switch S2. Detailed descriptions of each switch follow the table.

Possible Bit Rate Settings - Switch S1-1, S1-2 and S2-1

S1-1	S1-2	S2-1	Sync Data Rate	Async Data Rate
On	On	Off	32 kbps	Reserved
Off	On	Off	56 kbps	Reserved
On	Off	Off	64 kbps	Reserved

On	ON	On	Reserved	Reserved
Off	On	On	Reserved	Reserved
On	Off	On	Reserved	Reserved
Off	Off	On	19.2 kbps	Reserved

Switch S1-3: Data Set Ready During Line Loopback Test

Use Switch S1-3 to control the behavior of the DSR signal at the EIA interface during the line loopback test.

S-3	Setting
On	DSR is on during local line loop
Off	DSR is off during local line loop

Switches S1-4: Management Setting

When setting the 1092A to SNMP Management, the DTE rate switches (S1-1, S1-2, and S2-1) are also needed to be at the ON position. Therefore, to set a 1092A unit SNMP management mode, the following switches have to be at the ON position, S1-1, S1-2, S2-1, and S1-4.

Use Switch S1-4 to configure the 1092A’s management setting.

S1-4	Setting
On	SNMP Management
Off	Control Port Management

Switches S1-5: Reserved

Always at off position

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

Use Switches S1-6 and S1-7 to configure the 1092A for internal, external, or receive recover clock mode.

S1-6	S1-7	Clock Mode	Description
On	On	Internal	System clock
			generated internally
Off	On	External (DTE)	System clock derived
			from terminal interface
On	Off	Receive Recover	System clock derived
			from the received line
			signal.
Off	Off	Hardware Reset	Reset to use hardware
			switches for
			configuration
