Patton electronic 1092 Configuring the Hardware DIP Switches, Configuration DIP Switch Set S1

3.0 CONFIGURATION

The Model 1092 is equipped with two sets of eight DIP switches, which allow configuration of the unit to a wide variety of applications. The Model 1092 is also equipped with an internal switch that allows selection of 115 or 230 VAC power inputs (Note: this switch is not present in Models 1092-UI and 1092-DC). This section describes switch locations and explains all possible configurations.

3.1 CONFIGURING THE HARDWARE DIP SWITCHES

The Model 1092 uses a unique set of 16 external mini DIP switches that allow configuration to wide range of applications. The 16 external switches are grouped into two eight-switch sets, and are externally accessable from the underside of the Model 1092 (See Figure 1).

	S2
	ON
	ON
	1	2	3	4	5	6	7	8
Back	ON							Front
	1	2	3	4	5	6	7	8
	OFF
	S1

Figure 1. Underside of Model 1092, Showing Location of DIP Switches

The two sets of DIP switches on the underside of the Model 1092 will be referred to as S1 and S2. Figure 2 shows the orientation of all DIP switches is the same with respect to “ON” and “OFF” positions.

3.1.1 Configuration DIP Switch Set “S1”

The configuration switches on S1 set data rate, asynchronous or synchronous data format, transmit clock source and response to RDL request. The default settings and detailed descriptions for each switch are shown below.

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	Async/Sync Data Format	Off	}	Async/Sync
S1-5	Async/Sync Data Format	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 to configure the asynchronous or synchronous data rate of the Model 1092. Each setting represents one synchronous data rate and one asynchronous data rate.

S1-1	S1-2	Sync Data Rate	Async. Data Rate
On	On	32 Kbps	Reserved
Off	On	56 Kbps	Reserved
On	Off	64 Kbps	Reserved
Off	Off	128 Kbps	0 - 38.4 kbps

NOTE: The Model 1092 can also operate at the 19.2 kbps synchronous rate. To operate at 19.2 synchronous, set Switches S1-1 and S1-2 both to the OFF position and Switch S2-1 to the ON position (see Section 3.2.1 for a description of Switch S2-1).

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
