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. 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 the 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 in a card. Direct connections are used for
devices that reside near the DTC. Modem connections are essential
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. If the DTC management is PC-based (that is, managed by an
OpenView Windows Workstation), you may have 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. Terminals are examples of non-nailed devices
for PC-based management. - Terminal and Printer Profiles
Each port needs a profile assigned to it.
A profile defines a set of characteristics for a terminal, printer,
or another serial device. A profile can be of five types: a terminal
profile, a PAD terminal profile,
a printer profile,
PAD printer profile, or a host profile.
Refer to Chapter 7 “Terminal and Printer Profiles” for
more information on 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.
