Patton electronic Model 1065 user manual Configuration Switch SET S2, S2 Summary Table

Switch S1-8: Carrier Control Method

The setting for switch S1-8 determines whether the carrier is “con- stantly on” or “controlled by RTS”. This setting allows for operation in switched carrier, multipoint and/or hardware handshaking applications.

S1-8	Setting
Off	Constantly on
On	Controlled by RTS

3.3 CONFIGURATION SWITCH SET “S2”

The DIP switches on S2 set word length, extended signaling rate, RTS/CTS delay, V.52 and V.54 diagnostic test and 2- and 4-wire opera- tion.

S2 SUMMARY TABLE

Position	Function	Factory Default
S2-1	Word Length	Off	} 10 bits
S2-2	Word Length	Off
S2-3	Extended Signaling Rate	Off	-2.5% to 1%
S2-4	RTS/CTS Delay	On	} 7 ms
S2-5	RTS/CTS Delay	On
S2-6	2-Wire/4-Wire	On	(4-Wire) FDX
S2-7	2-Wire/4-Wire	Off	(4-Wire) FDX
S2-8	V.54	Off	V.54 Enabled

Switches S2-1 and S2-2: Word Length

Switches S2-1 and S2-2 are set in combination to determine the word length for asynchronous data, including the start and stop bits.

S2-1	S2-2	Setting
Off	On	8 bits
On	On	9 bits
Off	Off	10 bits
On	Off	11 bits

Switch S2-3: Extended Signaling Rate

The setting for switch S2-3 determines the range of variability the Model 1065 Series “looks for” in asynchronous data rates (i.e., the actual variance from a given frequency level the Model 1065 Series will tolerate).

S2-3	Setting
Off	-2.5% to +1%
On	-2.5% to +2.3%

Switches S2-4 and S2-5: RTS/CTS Delay

The combined settings for switches S2-4 and S2-5 determine the amount of delay between the time the unit “sees” RTS and when it sends CTS. Options are no delay, 7 ms and 53 ms.

S2-4	S2-5	Setting
On	On	7 ms
Off	On	53 ms
On	Off	No delay
Off	Off	No delay

Switch S2-6 & S2-7: 2-Wire/4-Wire Mode Selection

The setting for switch S2-6 and S2-7 determines whether the Model 1065 Series is operating in 2-wire or 4-wire mode.

S2-6	S2-7	Setting
On	On	4-wire (half duplex)
On	Off	4-wire (full duplex)
Off	On	2-wire (half duplex)

Switch S2-8: V.54 Loopback Test Enable

This switch enables or disables V.54 looping in the Model 1065.

S2-8	Setting
Off	V.54	Normal Operation Enabled
On	V.54	Testing Disabled
