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 functions on the
1065RC.
S2-8 Setting
Off V.54 Normal Operation
On V.54 Testing Disabled
3.4 CONFIGURATION SWITCH SET “S3”
The DIP switches on S3 set the antistream control, local loopback
enable, remote loopback enable and receive (input) impedance levels
for the Model 1065RC. The default settings are shown in the S3 sum-
mary table.
S3-1: Input Impedance
The setting for switch S3-1, S3-2 determines the 1065RC’s input
impedance. This allows you to choose the optimum impedance setting
for your application. In long distance applications the impedance of the
cable must match the impedance of the load (or resistor) of the Model
1065RC. Thicker gauge cables requires a lower ohm setting, while a
thinner gauge cable should receive a higher ohm setting. See Figure
5.1 for a more details on selecting a setting.
S3-1 S3-2 Setting
On On 130 ohms
On Off 200 ohms
Off On 320 ohms
Off Off High impedance (minimum 2k ohms)
