We use the pdu with the ipkvm thing, so this info isn't needed, might come in handy at some point tho. | |||

Default behaviour is to act as a fairly dumb power strip - after a few seconds, all the outputs are turned on in sequence and remain on. | |||
The control connection is RS232 to the RJ45 'IN' connector, as described in table A.19 of the manual above. This indicates the following connections to a 9-pin PC-AT RS232 connector, assuming the signals are crossed in the same way as a chained PM20i. | |||

It doesn't make sense to connect the two DSR pins together. This occurs because in chaining the units, pin 8 is connected anyway by the RJ45 cable and is presumably not used. | |||
Connecting this to a PC running Kermit at 9600 baud, I got an immediate login prompt. The unit I tried had the factory default users set - no groups or usernames, user admin has password pm8. I didn't have to set any special line conditions so it's possible a 3-wire data-only connection would do. | |||
If you need to reset the password, see [http://jhigham.blogspot.co.uk/2011_05_01_archive.html loopback plug wiring] (link pins 1-8, 2-7, 3-6) |
