Patton electronic 1186 POWER CONNECTION 4.3.1 Universal AC Power 100-240VAC, DC Power, Power-Up

4.3 POWER CONNECTION

4.3.1 Universal AC Power (100-240VAC)

The Model 1186 uses a 5VDC, 2A universal input 100-240VAC, power supply (center pin is +5V). The universal input power supply has a male IEC-320 power entry connector. This power supply con- nects to the Model 1186 by means of a barrel jack on the rear panel. Many international power cords are available for the universal power supply (Please refer to Appendix B for country-specific power cords).

The Model 1186 powers up as soon as it is plugged into an AC outlet. The unit does not have a power switch.

4.3.2 DC Power

The 36-60 VDC DC to DC adapter is supplied with the DC version of the Model 1186. The black and red leads plug into a DC source (nominal 48VDC) and the barrel power connector plugs into the barrel power supply jack on the rear panel of the 1186. (See Figure 9).

5.0OPERATION

Once the Model 1186 is properly configured and installed, it should operate transparently. This section describes power-up, reading the LED status monitors, and using the built-in loopback test modes.

5.1 POWER-UP

To apply power to the Model 1186, first be sure that you have read Section 4.3, and that the unit is connected to the appropriate power source.

Next, make sure that front panel switches are set to Normal condi- tion. Then, plug provided power adapter (see section 4.3) first into the rear panel outlet of the Model 1186, and then into the acceptable power outlet (AC or DC depending on the model -UI or -DC). After both the local and remote Model 1186s are powered up, a synchronization process will occur to establish a link. The synchronization process should take only a few seconds (<5 sec). Any time one of the Models 1186 loses power (i.e., in a lightning storm), the local and remote units will re-synchronize before they can resume data transmission.

When the local and remote units have established a link and are passing reliable data, the following LED conditions will exsit:
