Page 6: Configuration Overview
3.0 CONFIGURATION OVERVIEW The Model 1140 is fairly simple to install and is ruggedly designed for excellent reliability: just set it and forget it. The following instructions will help you set up and install the Model 1140 properly. If you have any questions, don't hesitate to call B&B’s Technical Support Department at (815) 433-5100 (8-5 PM, CST). -
Page 7: Configuration Switch Set "S1
The Model 1140 has two sets of eight switches, yielding 16 total DIP switches. The three sets will be referred to as S1 and S2. As Figure 2 shows, the orientation of all DIP switches is the same with respect to "ON" and "OFF" positions. Figure 2. -
Page 8: S1-1 Through S1-4: Data Rate Setting
S1-1 through S1-4: Data Rate Setting Switches S1-1 through S1-4 are set in combination to determine the asynchronous and synchronous data rate for the Model 1140. S1-1 S 1-2 S1-3 S1-4 Setting 1.2 Kbps 1.8 Kbps 2.4 Kbps 3.6 Kbps 4.8 Kbps 7.2 Kbps 9.6 Kbps... -
Page 9: S1-8: Carrier Control Method
S1-8: Carrier Control Method The setting for switch S1-8 determines whether the carrier is "constantly on" or "controlled by RTS". This setting allows for operation in switched carrier, rnultipoint and/or hardware handshaking applications. S1-8 Setting Constantly On Switched Carrier 3.3 CONFIGURATION SWITCH SET "S2" The DIP switches on S2 set word length, extended signaling rate, RTS/CTS delay and V.52 and V.54 diagnostic test. -
Page 10: S2-3: Extended Signaling Rate
S2-3: Extended Signaling Rate The setting for switch S2-3 determines the range of variability the Model 1140 "looks for" in asynchronous data rates (i.e., the actual variance from a given frequency level the Model 1140 will tolerate). S2-3 Setting -2.5% to +1% Basic -2.5% to +2.3% Extended S2-4 and S2-5: RTS/CTS Delay The combined settings for switches S2-4 and S2-5 determine... -
Page 11: Installation
4.0 INSTALLATION The Model 1140 is easy to install. After configuring the DIP switches, simply connect the two fiber cables and then connect the RS-232 interface. Figure 5 shows the location of the fiber connections on the Model 1140's rear panel. Figure 5. -
Page 12: Operation
5.0 OPERATION Once you have configured each Model 1140 properly and connected the fiber and RS-232 cables, you are ready to operate the units. This section describes the LED status monitors, the V.52 and V.54 diagnostics and the power up process. 5.2 TEST MODES The Model 1140 offers two V.54 test modes to evaluate the condition of the modems and the communication link. -
Page 13: Remote Digital Loopback (Rdl)
A. Activate LAL. This may be done in one of two ways: First, by moving the front panel toggle switch DOWN to "LAL". Second, by raising pin 18 on the interface. (NOTE: Make sure DIP switch SW1-8 is OFF). Once LAL is activated, the Model 1140 transmit output is connected to its own receiver. -
Page 14: Using The V.52 Ber Test Independently
5.2.3 USING THE V.52 BER TEST INDEPENDENTLY The V.52 BER test can be used independently of the V.54 loopback tests. This requires two operators: one to initiate and monitor the test at the local Model 1140, and one at the remote Model 1140. -
