APC UPS To SEB Netpath

APC UPS To SEB Netpath

APC UPS To SEB Netpath

I am attempting to set up a APC UPS to a port on our new SEB Netpath modem.  We are going from a serial port on the network card on the APC to an RJ 45 port on the back of the SEB. I am sure this will require a DB-9 to RJ-45 cable. Is there anyone there who might have done this and knows the pinout of this cable?  Looking to share your trials and tribulations and any possible ideas.



RE: APC UPS To SEB Netpath

The NetPath host ports are configured as DTE.

Here are signals on a DB9 from a NetPath RJ45. Note: If the UPS serial port does not provide DSR, you will need to loop back the DSR & RTS signals in the DB9 connector (pins 6&7)

DB9 PIN #     Function       RJ45 PIN #
   1           DCD (in)           2
   2           RD  (in)            5
   3           SD  (out)          6
   4           DTR (out)         3
   5           GRD                 4
   6           DSR (in)           1
   7           RTS (out)         8
   8           CTS (in)           7
   9           Not Used
