I have a digi TS/4 that I need to connect to an HP-UX Server rp5405 but I can not find any documentation on which cable to purchase. I know I need rj45 to DB9 but does it need to be crossover or straight through? This will be used for console access.

Thanks very much!

You need the “crossover” RJ-DB9 cable.
