The handbook goes over this. Your cable is indeed wrong. http://www.freebsd.org/doc/en/books/handbook/serial.html#SERIAL-CABLES-PORTS And these are from our internal notes, specifically for use with our serial console device (MRV LX-4016S) which uses RJ45 for serial. The pin names I've labelled appropriately, so you should be able to figure out what your cable should be. And yes, these work with hardware flow control, and are *reliable* on FreeBSD. We use the gettytab entry "std.115200" for them, with no character loss. ---------------------------------------------------------------------- The LX-4016S-001 sports sixteen (16) RJ45 connectors. The cabling for the console port (Diag/Mgmt Port, also known as Port 0) comes with the unit. The cable to use for this port appears to be some sort of rollover cable (Cisco?); it's silver and flat, not round like CAT5. It's 8-pin though. A DB9 adapter also comes with this cable, which allows you to hook it up to a standard PC and access it. Ports labelled 1-16 require RJ45-to-DB9 adapters for hooking the MRV up to actual servers in the rack. The adapters that work best are the Xyplex XFDCE91 adapters, which support hardware flow control (RTS/CTS) and come pre-assembled. You can find the product here: Xyplex adapter XFDCE91 RJ45-to-DB9 APACN p/n 24490-15 -- http://www.apacn.com/ Pinout/wiring diagram: RJ45 DB9 Female Female =========== ======= (CTS) 1 <----> 7 (RTS) (DTR) 2 <----> 6 (DSR) (TxD) 3 <----> 2 (RxD) (TxD GND) 4 <----> 5 (GND) (RxD GND) 5 <----> 5 (GND) (RxD) 6 <----> 3 (TxD) (DSR/DCD) 7 <----> 4 (DTR) (RTS) 8 <----> 8 (CTS) Pins 1 (DCD) and 9 (RI) on the DB9 are unconnected/unused. With these adapters, use standard (not crossover!) CAT5/6 cables. ---------------------------------------------------------------------- -- | Jeremy Chadwick jdc at parodius.com | | Parodius Networking http://www.parodius.com/ | | UNIX Systems Administrator Mountain View, CA, USA | | Making life hard for others since 1977.
