Connector cards (also called boards) in the DTC allow terminals,
printers, and other serial devices to be connected to the DTC for
communication with an HP 3000 Series 900. You can use the DTC Card
Configuration worksheet as shown later in this Chapter, to record the values
selected for each DTC card.
For each connector card in a DTC, you must define the characteristics of its
ports for connection to terminals, printers, and other serial devices. The
following parameters are required.
- Card Number
- The card number specifies which card in the DTC is being configured.
DTC 16s allow 2 connector cards, labeled card # 0 and card # 1, with the
third slot (card # 2) reserved for a DTC/X.25 Network Access card. When
looking at the rear panel of the DTC, card # 0 is located on the left,
card # 1 is in the middle, and card # 2 is on the right.
DTC 48s allow up to 6 connector cards, labeled card # 0 to 5.
DTC 72MXs allow up to 3 connector cards plus a LAN card that is
preinstalled in slot 0; the connector cards are labeled card # 1 through
3.
For the DTC 48 and 72MX, card # 0 resides at the bottom of the DTC and
card # 1 resides above it, and so on.
Note that DTC 16iX/16MX/16RX does not have connector cards. Its port
connectors are built directly onto its backplane.
- Direct or Modem Connect
-
You must specify whether a direct or modem connection is used for the
ports on a card. Direct connections are used for devices that reside
near the DTC. Modem connections are used for communications over
telephone lines.
- Port Number
-
Each port on a connector card is assigned a number, starting with port #
0 on the left most side of the card.
- Logical Device Number (LDEV)
- Each port needs a logical device (ldev) number assigned to it, if the
DTC is managed by an HP 3000. The ldev number is used by MPE/iX to
designate devices. Devices with ldevs permanently assigned to them are
called nailed devices. Printers and UPSs, as well as devices that
will be programmatically accessed, must be nailed devices. Each nailed
ldev number assigned in NMMGR must be unique.
For host-based DTC management, you may have PAD ports without ldev
numbers assigned to them; hence they are non-nailed devices.
Non-nailed devices have ldev numbers that are assigned from a pool of
available ldev numbers for the duration of the device connection to the
system.
- Terminal and Printer Profiles
- Each port needs to be assigned a profile. A profile defines a set of
characteristics for a terminal, printer, or another serial device. A
profile can be of five types: terminal
profile, printer profile,
PAD terminal profile, PAD printer profile, or Host port
profile. See Configuring Systems for Terminals, Printers, and
Other Serial Devices manual for more information on the
characteristics determined by the profiles, and a list of the profiles
that are supplied in the sample configuration file.
If the characteristics provided in the sample profiles are different
from those required by the terminals and printers connected to your DTCs,
then you can define new profiles.
It is suggested that you use default profiles TR10D96 for
direct connect terminals and PR18D96 for direct connect
printers or PR22D24 for HP printers with status checking. For
PAD terminals and printer, use the defaults TR24PAD and
PR26PAD, respectively. For UPSs, use the default profile
UP10D12.
The name of the profile can be up to eight characters long and must
start with a letter, followed by letters and numbers. At any one time,
up to 1024 profiles can be configured per system.
