Selecting Device Drivers for Your Interface Cards

The following sections describe each interface and their connectivity to peripherals.

Asynchronous Data Communication Configuration Guidelines

HP-UX multiplexers provide asynchronous data communication using protocols RS-232-C, RS-422, or RS-423 (depending on the card). All HP-UX computers are equipped with RS-232-C serial ports. Additional serial cards increase the number of connections possible between the system processor unit (SPU) and terminals, modems, printers, and uninterruptible power system (UPS). Table 2-2 “Multiplexer Connectivity Configuration Requirements” summarizes the scope of HP cards, architecture, and drivers available. It also identifies the port modules (distribution panels) available for each serial card.

The two ports of this card can be used for console and remote console only. ^[10]Personality card also includes AP, SCSI, parallel.

Distribution Panels for Asynchronous Connectivity

Distribution panels (DDPs, ADP/MDPs) can be used to expand the connectivity between serial interface card and peripheral device. Data communications and terminal controllers (DTCs) provide additional serial connectivity for local or remote devices directly to the LAN. These mechanisms are illustrated in Figure 2-2 “Serial Connectivity via Distribution Panels or DTC”

Figure 2-2 Serial Connectivity via Distribution Panels or DTC

Table 2-1 “Maximum Recommended Device Connections by Interface” summarizes the distribution panels and their capabilities. All distribution panels listed provide connectivity for terminals, printers, and plotters. Those with full duplex modem control provide connectivity for modems also.

Data Communication and Terminal Controllers (DTC)

Data communication and terminal controllers (DTCs) are stand-alone boxes that connect to the LAN to provide additional serial connections for local or remote devices. Unlike serial interface cards, which communicate directly with the core operating system, DTCs use Telnet-TCP/IP protocols to communicate with the peripheral devices. Therefore DTCs provide most, but not all, the same functionality. Two types of DTCs are available:

DTC 16MX telnet terminal server (J2063A), providing direct connection for LAN, diagnostics, and up to 16 serial-connected peripherals.
DTC 16RX telnet terminal server (J2064A), providing routable management in addition to direct connection for LAN, diagnostics, and up to 16 serial-connected peripherals.
DTC 72MX communications server (J2070A), providing LAN, telnet access, X.25 access, and connection for up to 72 serial-connected peripherals via an asynchronous processor board.

DTCs must be configured by one of two DTC software products, HP OpenView DTC Manager (HP part number D2355A) and HP DTC Manager/UX (HP part number J2120A), both of which can be used with HP-UX systems. Consult your HP Sales Representative for full information.

RS-232-C Cabling Guidelines

For cabling purposes, serial devices may be thought of as Data Communications Equipment (DCE) or Data Terminal Equipment (DTE). Historically, DCEs were modems, and DTEs were whatever terminated the data path, typically a terminal at one end, and computer at the other. When transmitting remotely, the circuit may be shown diagrammatically as follows, with the active pins listed in Table 2-4 “DCE and DTE Pin Assignments”

Computer[DTE]-{ DCE~~phone lines~~DCE }-[DTE] terminal

Table 2-4 DCE and DTE Pin Assignments

	DCE Pins	DTE Pins
Transmit^[1]	3	2
Receive	2	3
Monitor	4,20	5,6,8,22
Assert	5,6,8,22	4,20
Ground	7	7
^[1]For simple serial I/O, only transmit, receive, and ground are required.

Table 2-5 “RS-232-C Interconnections” provides a quick reference to RS-232-C cabling between serial devices and an HP-UX system. Neither RS-422 nor direct CPU-to-CPU connections are tabulated.

Centronics (Parallel) Configuration Guidelines

The centronics (parallel) interface allows characters to transfer over multiple data lines, one bit per line. This method of transfer results in faster speed than serial transmission and is preferred for configuring printers, plotters, and scanners.

On Series 700 workstations, the centronics (parallel) interface is provided as a standard feature; Series 800 systems may have a parallel interface on the multi-functional I/O card (personality card) supplied standard with the computer or on an optional SCSI/Centronics interface card. Centronics is not supported on Series 800 CIO systems.

Table 2-6 Centronics Configuration Requirements

Architecture	Interface card	Interface Driver
Series 700 Core I/O	(internal)	`CentIf`^[1]
Series 800 HP-PB	28655A	`lpr0`
^[1]Specifying `CentIf` causes `ChrDrv` to be included in the kernel.

EISA Configuration Guidelines

When configuring an interface card to the EISA bus, the eisa device driver must be present in the kernel, that is, it must be listed in /stand/system.

Because EISA is a set of services used by other interfaces, configuring EISA cards is done differently than for other HP-UX interfaces. Refer to Appendix A “EISA Board Configuration”/sbin/eisa_config utility.

Swapping to an EISA Device

If you are adding a device to your system that you plan to use as a primary swap device, and the device will be connected to an EISA card, you must perform the task in the following order:

Shut down the system without changing the kernel (still swapping to the original swap device).
Add the EISA card and connect the new device.
Boot the system, which is still swapping to the original swap device.
Configure the kernel to swap to the new EISA device.
Reboot the system.
If the new swap device is connected to an EISA card, it will be configured automatically by /sbin/eisa_config. If the new card creates a resource conflict with EISA cards already configured, you must run eisa_config manually to resolve the conflict. If the new swap device is connected to an ISA card, you must run eisa_config manually to configure the new swap device.

Graphics Card Configuration Guidelines

The following table shows the driver and device special files used by graphics cards and subsystems.

Table 2-7 Graphics Card Configuration Requirements

Architecture	Required Drivers	Default Device Special Files
Series 700 all models Series 800 Models 8`x`9	`graph3`^[1]	`/dev/crt` `/dev/crt0` `/dev/crt1` `/dev/crt2` `/dev/crt3` `/dev/ocrt` `/dev/ocrt0` `/dev/ocrt1` `/dev/ocrt2` `/dev/ocrt3`
^[1]Specifying `graph3` causes `wsio`, `ite`, and `framebuf` to be included in the kernel.

During system bootup, ioinit creates the default device special files shown in this table when it encounters the framebuf driver.

If for any reason these device files are insufficient for your purposes, you can create new ones using mknod. As shown in /usr/conf/master.d/core-hpux, the major number for framebuf (the driver that provides the additional graphics capability) is 174. A character (raw) device special file is required. Use the bit assignments shown for graph3 interface driver in Table C-5 “Bit Assignments for Disk and Magneto-Optical Devices” in Appendix C “Major and Minor Numbers” of this document.

Graphics capabilities can be enhanced by installation of any of a growing family of cards and subsystems. Table 2-8 “Graphics Enhancement Capabilities” is intended only to give a rough idea of the possibilities available on HP workstations. Consult your HP Sales Representative for information targeted to your specific needs.

Graphics Cable Extensions

The following extensions are available for placing the CRT a distance away from the SPU:

46082A/B: RGB extension
46080/81A: HIL extension
1250-1287: Use three of these connectors to extend RGB cable for a Model 712.

There is no PS/2 keyboard or mouse extension available for the Model 712.

Maintaining the Accuracy of Customized Graphics Configurations

Any time you modify your graphics configuration, be sure to update the configuration files used by your application programs.

For example, if you are adding a CRX24 (or CRX48) and using it as a console, you must

Note the hardware path in which you insert the card.
Identify the device special file for the CRX24. By default, the minor number of the console device special file is 0x000000.
Make sure the files in the /etc/X11 directory refer to the correct device special file for the console.
Change the console path in BOOT_ADMIN to match the hardware path into which you insert the card. For example,
BOOT_ADMIN> path console graphics2
You can display the correlation between the PDC names and hardware paths by using the info query at the BOOT_ADMIN prompt.

Networking Configuration Guidelines

HP Series 700 and 800 systems shipped with LAN ports on the personality (multi-functional) or core I/O boards provide network access through AUI LAN, ThinLAN, or EtherTwist. (Note, the two ports on the standard LAN personality card are mutually exclusive; you can use either, but not both ports simultaneously.)

Additional networking options are available for HP-UX systems. Table 2-9 “Network Interfaces and Initial Configuration Requirements” summarizes their initial configuration requirements.

All network products require a layered set of software — links, transports, and services — whose details fall beyond the scope of this document. Consult networking documentation for further information.
