Defining the DTC Connector Cards
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 in Figure 2-3 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 You must specify whether a direct or modem
Connect 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 Each port needs a logical device (ldev) number
Number (LDEV) 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 Each port needs to be assigned a profile. A
Profiles 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.
