Thanks to another great find by members over at Serve The Home forums, I picked up a couple of Baytech RPC-3 remote PDUs for dirt cheap.
Once both units were rewired it was time to configure them. One of the switches didn’t come with an IP address sticker and I tried unsuccessfully to discover the IP address manually. It was becoming apparent that I’d have to configure the switch via serial connection.
Unfortunately the baytech units use a non-standard DB9 to RJ-45 cable. Thankfully, Good Guy Baytech supplies the complete pinout in the manual so that you can make your own cable.
Note: The diagram assumes that this cable will be used with a Null Modem (rollover cable) and is pinned out as such
Making the cable is very straight forward. All that was needed was a short Cat-5e Patch cable, a female DB9 connector and some basic soldering skills. Simply cut the end of the patch cable, follow the pinout diagram and match up the wire colors in the opposite end of the cable to the proper DB9 pins. I ended up simply writing down the colors to pin matching so the soldering job went faster
Fortunately the console was not password protected so it was easy to change the admin password. If however the console was passworded here are the reset instructions for Baytech RPC3’s
1. Turn off the power to the RPC3
2. Remove the lid
3. Locate JP1 on the Ethernet board
4. The jumper is placed on pins 1 and 2, move it to 2 and 3
5. Turn power on for 10 seconds
6. Turn power off
7. Return jumper to its original position.
One last order of business before racking up the units was to provide a GUI driven interface for the unit. Since the RPC-3 uses basic command line telnet connection it was relatively easy to develop a basic app to control and monitor the unit remotely. Few hours of coding and I came up with a simple app that interfaces with the units.
The app can control individual outlets by right clicking on it, or many at once by selecting the check boxes and invoking an action.

The only complaint about these boxes is the master on-off button. I wish there would be some sort of cover over the switch as it’d be very easy to accidentally kill the entire pdu dropping all devices.
