I have come across what seems to be a remote outlet/power sequencer device On the rear it has two DB-9 male ports, which I assume can be used to program this device. It also has an Ethernet port and a few RJ-11 ports labeled "IN", "R1," and "R2." Additionally, a DB-15f port with the label "out" exists. I have tried to connect to the device using 9600/8/N/1 over the two serial ports (DB-9) using both a straight and null-modem cable, but my terminal emulator senses nothing. A bank of 8 dip switches exists with the label "config." I contacted the manufacturer, but they claim all of this information is archived and they do not have access to it. Does anyone have any ideas on how to communicate with this device? It powers on and supplies electricity to its six receptacles. Thanks, Geoff
