1.0 WARRANTY INFORMATION 2.0 GENERAL INFORMATION Patton Electronics warrants all Model 1035 components to be free from defects, and will—at our option—repair or replace the product should it fail within one year from the first date of shipment. This warranty is limited to defects in workmanship or materials, and does not cover customer damage, abuse or unauthorized modification. If this product fails or does not perform as warranted, your sole recourse shall be repair or replacement as described above.
.0 CONFIGURATION 3.2 OPENING THE CASE The Model 1035 provides sixteen configuration switches, which allow selection of data rates, clocking methods, V.54 test modes, RTS/CTS delay and DTE control of test functions. This section describes switch locations and explains all possible switch configurations. Open the unit by gently inserting a screwdriver into the special pry slot on the plastic case (below). You don't have to worry about breaking the plastic. 3.
SWITCH SET SW1 SW1-8: V.54 Enable/Disable The configuration switches on switch set SW1 set analog loopback, digital loopback and V.54 enable/disable. The default settings are summarized in Figure 3 (below). The setting for switch SW1-8 determines whether or not the Model 1035’s V.54 circuits are enabled. SW1 SUMMARY TABLE Position Function Setting V.54 test functions disabled V.
4.0 INSTALLATION SW2-4 and SW2-5: Clock Source Switches SW2-4 and SW2-5 are set in combination to determine the synchronous clock source for the Model 1035. SW2-4 On Off On SW2-5 On On Off Setting Internal transmit clock Receive recover clock External transmit clock SW2-6: Carrier Control Method The setting for switch SW2-6 determines whether the carrier is “constantly on” or “controlled by RTS”. This setting allows for operation in switched carrier, multipoint and/or hardware handshaking applications.
When connecting two Model 1035s, it is necessary to use a twisted pair “crossover” cable. The diagram below shows how a crossover cable should be constructed for an environment where both Model 1035s use a 6-wire RJ-11 connector. Similar logic should be followed when using RJ-45 connectors or a combination of the two. † ‡ SIGNAL PIN# COLOR‡ GND† RCV XMT XMT RCV GND† 1 2 3 4 5 6 Blue .................White Yellow ..............Red Green...............Black Red ..................Yellow Black ..........
5.0 OPERATION 5.3 TEST MODES Once the Model 1035 is properly configured and installed, it should operate transparently—as if it were a standard cable connection. Section 5.0 describes reading the LED status monitors, powering-up and using the built-in V.52 and V.54 test modes. The Model 1035 is powered by a 7.5V DC external wall mount transformer. To power up the unit, connect the power supply cord to the power jack on the rear of the Model 1035 and plug the power adapter into the wall.
APPENDIX A A. Activate RDL. This may be done in two ways: first, by moving the front panel toggle switch UP to “RDL”. Second, by raising pin 21 on the interface. (Note: Make sure SW1-8 is OFF). PATTON MODEL 1035 SPECIFICATIONS B. Perform a BER (bit error rate) test on the system. C. If the BER test equipment indicates a fault, and the Local Analog Loopback test was successful for both Model 1035s, you may have a problem with the twisted pair line between the modems.
