4.2 CONNECTION TO THE TERMINAL DEVICE

The Model 2703 is wired as a DCE, and–when configured proper- ly–supports communication with a wide variety of terminal (DTE) devices. Compatible interface standards include EIA-530 (RS-422), CCITT X.21 and CCITT V.35.

All interfaces are supported on a female UD-26 connector (a sub- miniature 26-pin “D” connector designated the “alt A” in the EIA-232 Standard). The various physical/electrical connections mentioned above are achieved by changing the Model 2703’s DIP switch settings and attaching different adapter cables.

If you wish to construct your own terminal adapter cable, please consult the pinout diagram in Appendix B. If you wish to purchase a terminal adapter cable specifically designed to work with the Model 2703, please refer to the specific Patton part numbers listed in Appendix C.

4.3 CONNECTION TO THE POWER SOURCE

As described in Section 3.3, the Model 2703 is available with three power supply options: two AC and one DC. The two AC power supply options (Standard and Universal) use a female IEC power cord inter- face, for which Patton can supply various domestic and international power cords. Please refer to Appendix C for specific Patton part num- bers when ordering power cords. The DC power supply option uses a 3-pin terminal strip interface (Note: Please refer to the Model 2703 Service Manual for DC power supply wiring instructions).

5.0 OPERATION

Once the Model 2703 is properly configured and installed, it should operate transparently. This sections describes power-up, read- ing the LED status monitors, and using the built-in loopback test modes.

5.1 POWER-UP

To apply power to the Model 2703, first be sure that you have read Section 3.3, and that the unit has the proper voltage setting and fuse. Failure to do so could result in damage to the unit and connected equipment, and may constitute a fire hazard. Having checked the volt- age setting, plug the AC power cord into both the Model 2703 and the AC outlet. Then Power-up the unit using the rear Power switch. Note: the “Power” LED should glow when power is applied to the unit.

5.2 LED STATUS INDICATORS

The Model 2703 features four front panel LEDs that indicate the status of power, network connection, master clock and loopback test. Figure 6 (below) shows the front panel location of each LED.

Following Figure 6 is a description of each LED’s function.
