4 Chapter 4 Port to Device Cabling 41
Port to Device Cabling Overview Overview This chapter details the pinouts for the ports and cabling needed to connect the communications ports to the peripheral devices. NOTE 42 All RS-232 ports provide a standard RS-232 interface with full modem control signals and surge protection on every signal. All RS-422 ports are data-only with no modem control signals.
Port to Device Cabling DB-25 Port Module DB-25 Port Module DB-25 ports provide standard RS-232 DTE signals on all DB-25 female connectors, one for each connected device (see Figure 4-1). Figure 4-1 DB-25 port module connector orientation The pinouts for connectors on the DB-25 port modules are identical (Figure 4-2).
Port to Device Cabling Device Wiring 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).
Port to Device Cabling Device Wiring Depending on the specific signal requirements of the system peripheral devices, 3-, 4-, or 7-wire connections can be made. Figures 4-3 through 4-5 show the cable configurations for these connections. Figure 4-6 shows the pinouts for a modem cable.
Port to Device Cabling Device Wiring Figure 4-5 Cable pinouts - full modem control - terminal or printer Figure 4-6 Pinouts for modem cables 46 Chapter 4
Port to Device Cabling RJ-45 Port Module and Fan Out Cable RJ-45 Port Module and Fan Out Cable RJ-45 port modules (J2484A) and fan out cable ports provide standard RS- 232 (RS-422 for J2501A port modules) DTE signals on all RJ-45 female connectors, one for each connected device (see Figure 4-7).
Port to Device Cabling RJ-45 Port Module and Fan Out Cable The pinouts for all RJ-45 jacks are shown below (see Figure 4-8). Figure 4-8 RJ-45 jack pinouts 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). The RX- signal should be attached from the port module to the TX- signal of the device.
Port to Device Cabling 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.
Port to Device Cabling Modular Cables Figures 4-9 through 4-12 illustrate cabling schemes for various types of devices. These cables are not offered by Hewlett Packard but may be customer fabricated or purchased from other sources.

Troubleshooting and Diagnostics Overview Overview This chapter provides instructions for troubleshooting terminals, printers and modem installations after the ports are configured and enabled. It also describes how to run diagnostic program emux_diag. NOTE 68 emux_diag and emux_tty work with PCI MUX cards.
Troubleshooting and Diagnostics Troubleshooting Troubleshooting Following are some of the problems which may be encountered due to improper configuration of ports. Excessive Frequent getty Spawning Problem: A console message similar to the following appears: ‘tty1a1’ getty keeps dying. There may be a problem Cause: This message usually indicates that the incoming CD signal connected to a modem control port with CLOCAL set keeps toggling.
Troubleshooting and Diagnostics Troubleshooting Tests: 1. Log onto the console as root and verify that the port is enabled by executing emux_diag and selecting Port Status - Breakout Box to verify that the port is open. 2. Verify that the proper getty def entry has been selected for the port in the/etc/inittab file. Execute the following command (substituting the port in (question for tty1a1) from the console to display the terminal profile.
Troubleshooting and Diagnostics Troubleshooting • The port and printer are mismatched on baud rate, character size or parity • Printer losing stty settings after closing port Tests: 1. Use emux_diag Diagnostics to send data to the printer. Verify that cables and connectors are attached firmly and the printer is powered on and placed on-line. 2. If no data prints in step 1 above, check the port by placing a terminal in place of the printer and use emux_diag Diagnostics to send data.
Troubleshooting and Diagnostics Troubleshooting 1. Edit the /usr/lib/uucp/Devices file. For example, for a Hayes compatible 2400 baud modem (where 1a16 is the port where the modem is located): ACU cul1a16 2400 hayes NOTE Modem dial-in entries are normally created by using SAM on HP-UX 11i v1 and HP-UX 11i v2. System Administration Manager (SAM) is deprecated in HP-UX 11i v3. HP System Management Homepage (HP SMH) is the system administration tool for managing HP-UX 11i.
