Compatible with
Network General’s
Sniffer Server.
Choose from 8network port or 16network port models.
Works with Ethernet or
Token Ring networks.
Use to control test
equipment remotely.
Transparent to speed
and protocol.
Monitor and network
switches make
connecting or
disconnecting test
equipment easy.
Rackmountable.
T
he BLACK BOX®Monitor Access
Unit lets you connect Ethernet
or Token Ring networks to one test
device. It’s most commonly used
with Network General’s Sniffer
Server, but it also works with other
types of control, such as the VT100
menu interface and ASCII control
strings.
Models are available with 8
or 16 network ports. The 8-port
Monitor Access Unit comes with
RJ-45 connectors; and the 16-port
model is available with either RJ-45
or DB15 connectors. Choose the
one that’s right for your application.
For the RJ-45 models, all 8
leads are switched. These models
connect to any network that uses
RJ-45 connectors, such as Ethernet
10BASE-T, 100BASE-TX, shielded
twisted-pair (STP), or unshielded
twisted-pair (UTP) Token Ring
networks.
For the DB15 model, all 15 leads
are switched. It can be connected
to any network that uses DB15
connectors, including those with
RS-232, RS-422/RS-423 (RS-449),

Key Features
MONITOR ACCESS UNIT
RS-530, V.10/V.11, V.35, and Ethernet
AUI interfaces.
For connecting test devices to
networks, the Monitor Access Unit
uses sealed latching relays. These
relays ensure that the units operate
transparent to protocol and speed.
And, for added reliability, the relays
feature gold-clad silver contacts.
So, in the event of power failure,
the latching relays are designed to
remain in the last switched position.
The Monitor Access Unit’s
front-panel has a power ON LED
that lights when power is supplied
to the unit.
To connect or disconnect test
equipment to or from networks, use
the front-panel monitor switches
(MON1 and MON2). For operation
with a Sniffer Server, the monitor
switches are disabled. In a LAN
configuration, a Monitor Access
Unit can connect one Sniffer Server
to any of 8 or 16 networks.
The front panel also has
network switches that enable
you to connect test equipment to
networks. For operation with the
Sniffer Server, these switches are
also disabled.
The Access Unit’s actual
monitor ports and network ports
are on its rear panel, along with
its configuration DIP switches, a
chassis ground stud, and a power
socket.
Configuring the unit includes
setting the DIP switches for the
type of configuration that you’re
installing as well as its baud rate
and the monitor port identifiers.
These same DIP switches are
also used to configure the Monitor
Access Unit to operate with a
Network General Expert Sniffer
Network Analyzer.
For testing purpose, you can
disable the Monitor Access Unit
to operate it manually (however,
this can‘t be done if you use the
Monitor Access Switch with a
Sniffer Server).
The Monitor Access Unit
comes with two monitor cables, a
server communication cable,
a power cable, software, and a
users’ manual.
