your devices and are similar to a
serial port on a PC. When
connecting a modem, use a
standard serial cable. But when
you want to connect a PC or other
DTE device, use the (included) null-
modem cable.

Two of the RS-232 Ports

on both the 8-port and 16-port
models serve as the switch’s
System Set-Up Ports, which are
used for communicating during
initial set-up and configuration.
You can connect these ports either
to a PC or a modem. By connecting
to a modem, you can control the
device from a remote PC.

The Remote Console Port

Manager also has ”option
switches” on its back panel. These
eight DIP switches are used to set
the default baud rate, handshake,
message type, and duplex mode.
Though the option switches are by
default set to be compatible with
most applications, you can easily
change them to suit your needs.

Monitoring activity is a matter

of observing the instrument front
panel on the unit. The RDY LED
flashes to indicate that the Remote
Console Port Manager is
operational; the NET LED lights
when a network connection is
present; and the ACTIVITY LEDs
light to indicate data activity on
their corresponding ports.

• You wait more than 30

minutes to get through to a
vendor’s tech support.

• The so-called “tech” can’t

help you or gives you the
wrong answer.

• You don’t have a purchase

order number and the tech
refuses to help you.

• It’s 9 p. m. and you need help,

but your vendor’s tech
support line is closed.

According to a survey by Data

Communications magazine, 90% of
network managers surveyed say
that getting the technical support
they need is extremely important
when choosing a vendor. But even
though network managers pay

anywhere from 10 to 20% of their
overall purchase price for a basic
service and support contract, the
technical support and service they
receive falls far short of their
expectations—and certainly isn’t
worth what they paid.

best value and the best support.

Technical Support Experts before
