The DC+/S+ and DC-/S- are the output of each supply (very likely the two sections are completely isolated from each other). The S terminals are provided for remote sensing (a technique to compensate for voltage drop in long wires from the supply to the load). Ordinarily leave them jumpered. The RP terminal is likely "Remote Program", for setting the output voltage with an external resistor or network. Since the front panel control apparently works just use it and leave "RP" open. I don't know what PO an AT would be (Maybe "Power On" and "Attention?") but you probably don't need them either. >Does anyone know how to configure the back to send the juice to the >front >terminals? Maybe "PO" is "Panel Out" connected to the front panel + terminal (either AT or GND would be the minus terminal then). This could be checked with an ohmmeter. Measure the voltage at the DC/S terminal pairs, it should correspond to the meter reading. You could just run wires around from the back terminals to power your circuit. If you really want to use the front terminals you may need to take the cover off (hopefully I'm not insulting your intelligence by suggesting pulling the plug first) and try to trace the wires from them. There may be jumpers inside that disconnect the front panel ouptuts for example if the supply is used in a rack system.
