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.
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
