Converter Cables

RS-232 converter cables are available for adapting EISA/PCI Mux port

module and Fan out cable RJ-45 interfaces to devices or cables with HP

proprietary RJ-45 and DB-25 pinouts.

HP offers the following cables:

• J2488-60010 converts standard RS-232 RJ-45 pinouts to HP

proprietary RJ-45 pinouts (see Figure 4-13).

• J3830-60010 converts standard RS-232 RJ-45 pinouts to HP

proprietary DB-25 pinouts (see Figure 4-14)

NOTE J2489-60010 may be used in lieu of J3830-60010. J3830-60010 has two

nuts instead of screws and is in the unit of one instead of sixteen.

J3830-60010 replaces J4289-60010 as of May, 1998
