S1-7: DTE Control of RDL  
The setting for switch S1-7 determines whether the V.35 DTE can  
activate the RDL test by raising pin L. If DTE Control of RDL is  
enabled, control from the front panel is disabled if there is no DTE  
connected.  
Switches S1-1 though S1-4: Data Rate (Distance)  
Switches S1-1 through S1-4 are set in combination to determine  
two configuration parameters: synchronous data rate and maximum  
distance. Maximum distance is determined by the space between data  
packets in the communication stream between two Model 1180/35s.  
The "2X" setting doubles the space between data packets, when  
compared with the normal "1X" setting, and therefore doubles the  
maximum distance. A setting of "2X" facilitates communication  
distances up to 3 miles, and is available at certain data rates up to 64  
kbps. A setting of "1X" supports communication at the normal distance  
of 1.5 miles.  
NOTE: If DTE control is not avialable, set Switch S1-7 to off.

4.0 INSTALLATION  
5.0 OPERATION  
Once you have configured each Model 1180/35 properly and  
connected the fiber and V.35 cables, you are ready to operate the units.  
This section describes reading the LED status monitors, power-up, and  
using the built-in loopback test modes.  
The Model 1180/35 is easy to install. After configuring the DIP  
switches, simply connect the single fiber cable, hook up the V.35  
interface, and plug the power supply adapter into the 1180/35. Figure 4  
(below) shows the location of the interface connections on the Model  
1180/35 rear panel.  
5.1 LED STATUS MONITORS  
The Model 1180/35 features six front panel status LEDs that  
indicate the condition of the modem and communication link. Figure 6  
(below) shows the front panel location of each LED.  
Figure 4. Rear Panel of Model 1180/35 Showing Interface Connections  
4.1 SINGLE FIBER CONNECTION  
These short range modems are designed to work in pairs. You will  
need one at each end of single multi-mode fiber cable. Depending  
upon the data rate setting you select, your cable may be a maximum of  
1.5 or 3 miles long. The fiber cable connects to each Model 1180/35  
using either an ST or an SMA connector. Figure 5 (below) shows a  
close-up of both connector types.  
Figure 6. Front view of Model 1180/35  
• The green "Power" LED glows if power is applied to the modem.  
• The green "Test Modes" LED indicates that the modem is in a test  
mode (local analog or remote digital).  
• The "TD" and "RD" indicators blink red and green with data activity.  
Red indicates a low V.35 logic level, green indicates a high V.35  
logic level. Note: V.35 devices idle in a low state, so the LED will  
glow red if the connections are correct and the V.35 device is in an  
idle state.

Figure 5. Close-up of ST and SMA Connections  
4.2 V.35 CONNECTION  
• The "RTS" and "CD" indicators are also tri-state and will glow red for  
a "low" signal or green for a "high" signal. RTS lights for an  
incoming signal on V.35 pin C. CD lights for an incoming signal on  
the line side, and the resulting output signal on V.35 pin F.  
The Model 1180/35 is configured as a DCE. Therefore it “wants” to  
DTE hardware such as a PC, host or terminal, using a straight through  
V.35 cable. Connecting the Model 1180/35 to DCE hardware such as a  
modem, multiplexer, or printer, requires a null modem V.35 cable.  
Contact Patton Technical Support at (301) 975-1007 for more  
information about constructing the appropriate null modem cable for  
your application.

5.2 POWER-UP / SYNCHRONIZATION  
To perform a local loopback test, follow these steps:  
Apply AC power to the Model 1180/35 by plugging the separate AC  
power adapter first into the rear panel outlet of the Model 1180/35 and  
then into an acceptable AC power outlet. There is no power switch on  
the Model 1180/35: When the "power" LED is glowing steady, the  
Model 1180/35 is powered up. Note: be sure the front panel toggle  
switch on both Model 1180/35s is set to NORMAL.  
A. Activate local loopback by moving the front panel toggle switch  
DOWN to "Local". Once local loopback is activated, the Model  
1180/35 transmit output is connected to its own receiver. The "test"  
LED should glow. (Note: Even though the local Model 1180/35  
cannot communicate with the remote Model 1180/35 in this mode,  
the synchronized connection between the two modems remains  
intact).  
After both the local and remote 1180/35s are powered up, a  
synchronization process must occur between the two modems before a  
link can be established. Depending upon a number of factors, this  
synchronization process can take as long as 60 seconds. Any time one  
of the Model 1180/35s loses power (in a lightning storm, for example),  
the local and remote units must re-synchronize before they can resume  
data transmission. Note: If your application cannot tolerate a 60  
second synchronization phase, turning the front panel "Test Modes"  
switch to REMOTE and then back to NORMAL will synchronize the  
units within 250 mS.  
B. Verify that the data terminal equipment is operating properly and  
can be used for a test. If a fault is indicated, call a technician or  
replace the unit.  
C. Perform a BERT (bit error rate) test on each unit. If the BERT test  
equipment indicates no faults and the data terminal indicates a  
fault, follow the manufacturer's checkout procedures for the data  
terminal. Also check the V.35 interface cable between the terminal  
and the Model 1180/35.  
When both Model 1180/35s are powered up and passing data  
normally, the following LED conditions will exist:  
5.3.2 REMOTE LOOPBACK  
• PWR = green  
The remote loopback test checks the performance of the local and  
remote Model 1180/35s, and the communication link between them  
(see figure 7, on the following page). Any characters sent to the remote  
1180/35 in this test mode will be returned back to the originating device.  
For example, characters typed on the keyboard of the local terminal will  
appear on the local terminal screen after having been passed to the  
remote Model 1180/35 and looped back. To perform a remote loopback  
test, follow these steps:  
• TD & RD = flashing red and green  
• RTS & DCD = green  
• TEST = off  
5.3 LOOPBACK TEST MODES  
The Model 1180/35 offers two loopback test modes to evaluate the  
condition of the modems and the communication link. These tests are  
activated from the front panel.  
A. Activate remote loopback by moving the front panel toggle switch  
UP to "Remote". The "test" LED should glow.  
B. Perform a BERT (bit error rate) test on the system.  
5.3.1 LOCAL LOOPBACK  
C. If the BERT test equipment indicates a fault, and the local  
loopback test was successful for both Model 1180/35s, there may  
be a problem with the fiber communication line connecting the  
modems. You should test the fiber line for proper connections and  
continuity.  
The local loopback test checks the operation of the local Model  
1180/35, and is performed separately on each unit. Any data sent to  
the local Model 1180/35 in this test mode will be echoed back to the  
user device. For example, characters typed on the keyboard of a  
terminal will appear on the terminal screen.
