  • Page 16: Port To Device Cabling

    4 Port to Device Cabling Overview This chapter details the pin-outs for the ports and cabling needed to connect the communications ports to the peripheral devices. NOTE: All RS-232 ports provide a standard RS-232 interface with full modem control signals and surge protection on every signal.
  • Page 17: Device Wiring

    Figure 13 DB-25 connector pinouts Device Wiring Device wiring is dependent on the specific signal requirements of the system peripheral devices. Cable connectors plugged into the DB-25 port module ports must have a male DB-25 connector. The connector on the opposite end of each cable should mate to the peripheral device port (terminal, printer, personal computer or modem).

Figure 19 RJ-45 jack pinouts NOTE: In RS-422 terminology, RX- is sometimes labeled as RX(a) or Receive(a), while TX- is often labeled as TX(a) or Transmit(a).
  • Page 21: Modular Cables

    Modular Cables To support device-to-system connections at higher speeds over longer distances, customers may build their own cables using modular components. These cables commonly terminate on one end with an RJ-45 modular plug (connector) which fits into the modular jack on the port module or fan out cable, and on the other end with a DB-25 or DB-9 connector, depending on the type of the device.

  • Page 23: Converter Cables

    Figure 4- 1 2 shows cabling examples for RS-422 connections between the HP J2501A and common HP terminals. In all cases, the transmit pair of wires and the receive pair of wires should be twisted pairs to minimize crosstalk. Cable lengths of up to 1200 meters are supported for all data rates.
  • Page 24: Cabling For Ups And Disc Arrays

    HP offers the following cables: J2488-60010 converts standard RS-232 RJ-45 pinouts to HP proprietary RJ-45 pinouts (see Figure 4- 1 3). J3830-60010 converts standard RS-232 RJ-45 pinouts to HP proprietary DB-25 pinouts (see Figure 4- 1 4). 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.
  • Page 25 For the RJ45 type MUX (J2484A port module or the 8 port MUX card), use a "EISA MUX to HP-PB MUX" converter cable; J2489A RJ45-HP/DB25 converter (J3830-60010) and the default DB25 (5061-2569) UPS cable or the default DB25 cable for disc array.
