Black Box ME615A, ME615AE, ME616A, ME616AE Specifications
Async transmission up
to 115.2 kbps.
Operates full duplex
over 4-wire; halfduplex over 2-wire or
4-wire.
Meets ITU RS-485
requirements.
Operates over
multimode or singlemode fiberoptic cable.
Point-to-point or
multipoint applications
up to 32 units in
RS-485.
Miniature, lightweight,
and easy to install.
P
erfect for utility applications
such as the one shown in the
diagram on
page 2, the Async
Mini Fiber Optic Modem can
transmit an RS-485 signal via a
fiber optic link. The asynchronous
data rate can be up to 115.2 kbps
in full- or half-duplex mode.
The Modem performs
diagnostic loops in compliance
with the ITU V.54 standard. Two
V.54 loops are available: local
analog loop (loop 3) and remote
digital loop (loop 2). The loops are
activated by external DIP
switches on the top of the
Modem. Local digital loop is also
available.
The Modem includes a built-in
V.52 standard BER tester which is
also activated by an external DIP
switch on the top of the modem.
Transmit an RS-485
signal via a
fiber optic link.
Key Features
ASYNCMINIFIBER OPTIC MODEMS
Async Mini Fiber Optic
Modems models are all RS-485
with ST connectors. Select 115- or
230-VAC modems that work with
850-nm multimode or 1300-nm
single-mode fiber optic cable.
The Modem derives its power
from a standard wall-mounted DC
power supply adapter. The DC
voltage range is 300 mA to 9 V.
All the advantages of a fiber
optic system are yours with the
Modem:
• Lower attenuation than with
copper wire.
• EMI/RFI immunity, saving the
cost of expensive and heavy
shielding, and complex error-
checking routines.
• Almost absolute security;
you save money otherwise
spent for data encryption.
• Protects against
eavesdropping, since
negligible power radiates from
the fiber.
• Safety and electrical
isolation: no spark hazard and
no ground-loop problems.
Installing the modem is easy.
Simply set a couple of switches
and jumpers for full or half-duplex,
4-wire or 2-wire operation, and
carrier delay. Six diagnostic LEDs
tell you modem status at a glance.

Recognize any of these
situations?
• 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.
At Black Box, we guarantee
the best value and the best
support. You can even consult our
Technical Support Experts before
you buy if you need help selecting
just the right component for your
application.
Don’t waste time and
money—call Black Box today.
