The U.S. Robotics’ Sportster

has a DIP switch
that should be set as follows:
Switch Pos. Function
1UpDTR-normal
2UpVerbal Result Codes
3DnDisplay Result Codes
4DnNo Echo of Off-line Cmds
5UpAuto Answer on first ring
6UpCarrier Detect Normal
7UpLoad NVRAM defaults
8DnSmart mode
PLD version 1.04 and above has a modem auto
configuration capability. This feature will
configure most modems (including the US
Robitics modem described herein). To use this
feature connect the modem to the PLD “Head”
and power up the module.
19.3 Installation
As with other FOCUS modules, we recommend
that you initially install and test the PLD modules
and interfaces in “test” chassis (i.e., chassis that
are not part of an operating network). This way,
you can quickly perform the acceptance test
without interfering with a live network. Whether
you are installing the modules in test chassis or
chassis that are on-line in a network, use the
installation procedure described here.
The Party Line Data (PLD) Module occupies one
chassis slot and requires one time slot on the
T1/E1 line.
If you are installing multiple PLD modules, such
as a complete chain, or network, we recommend
that you install and configure the “head” module
first, followed by each “remote” module in the
chain, and then the “end” module. We also
recommend that, as you complete the hardware
installation and connections for each module, you
then complete the software configuration for that
module, before moving on to the next module/
chassis.
Before installing the module and its interface,
make sure that:
• The FOCUS chassis is set up, energized,
and operational, with all necessary
common equipment (see Chapter 3)
• The FOCUS Configuration Software (FCS)
has been installed on your terminal (see
Chapter 3)
• Acceptance tests for the FOCUS chassis
and all previously installed equipment have
been done to rule out invalid test results for
this module
• FCS is up and running (see the FCS online
help facility: FOCUS Configuration
Software > Starting FCS)
19.3.1 Hardware Installation and
Connections
To install the Party Line Data (PLD) Module and
interface, complete the following steps.
1. Bring the FOCUS chassis “on line”.
Click on the “Online” speed button
.
This uploads to the FCS the current status,
settings, operating statistics, etc., for the
FOCUS chassis — and the PLD module.
