Technical Specications
General Information
The Universal Data Transceiver is fully compatible with EIA standards for RS-232, RS-422 and
RS-485 at data rates from 0 (DC) to 2.1 mbps (200 kbps for RS-232) in the low speed mode
or from 10 kbps to 10 mbps in the high speed mode. It may be used for simplex or full
duplex asynchronous transmissions in both point-to-point systems and drop-and-repeat
data networks. It may also be used as a protocol converter. Although there are no operating
controls, the user must congure the unit for the protocol, speed and mode of operation
desired.
The Universal Data Transceiver comes in two versions, the 5012 stand-alone model and the
5018A card cage model. The two models are fully compatible with each other.

Operation Theory
Theory of Operation
The transmitting section of the universal data transceiver converts an incoming RS-232,
RS-422 or RS-485 signals into pulses of light at the transmitting LED located in the “Transmit
(or Tx)” optical connector on the unit. These pulses of light equate to ON for a positive input
level and OFF for a negative or zero input level.
The receiving section of the universal data transceiver produces a user selectable RS-232,
RS-422 or RS-485 compatible output from the received light at the photodiode located in
the “Receive (or Rx)” optical connector on the unit. Due to the fact that all internal logic
signals are converted to either light-on or light-o, any protocol may be used in conjunction with any other protocol, thereby allowing the transceiver to be used as a data
converter as well as a general data transceiver. In addition, provision is incorporated to
allow drop and repeat operation with any protocol.
During normal operation, the RTS line (terminal block position 6) is not used. In external
RTS operation (for RS-485), terminal block position 6 is used as an enable input to toggle
the unit between transmit and receive. In this mode a positive input switches the unit to
the transmit mode while a zero input switches the unit to the receive mode. As an alternative, the unit may be automatically switched from transmit to receive by means of an
internal data-driven timer (Data-Derived T/R switching).

Installation
Installation instructions
There are no operating controls on the universal data transceiver. Simply set the mode of
operation with the internal DIP switches and then connect the signal, power supply and
ber optic cables between the two units.
1. Connect the data processing equipment to be used to the 6 position terminal block
on the 5018A . Refer to the signal and power connections section on page 10 for specics.
Be certain that the various connections are made properly. Also be sure to only use
the positions called out for any particular protocol.
2. Set the internal DIP switches for the protocol, speed and mode of operation
according to the instructions beginning on page 10. Note: As provided from the
factory, the unit is set for RS-232, point-to-point.
3. Plug the unit into any free position in a model 6000A card-cage.
4. Connect the 5018A units together with two conductor ber optic cable. Be certain
that the “Transmit” connector of one unit is connected to the “Receive” connector of
the other unit.
5. The system should now be operational.
The transmitting element in the Fiberlink® 5018A transmitter
unit contains a solid state Laser Diode located in the optical
connector. This device emits invisible infrared electromagnetic
radiation which can be harmful to human eyes. The radiation
from this optical connector, if viewed at close range with no
ber optic cable connected to the optical connector, may be
sucient intensity to cause instantaneous damage to the
retina of the eye. Direct viewing of this radiation should be
avoided at all times!

After transmitting the last data bit, the above settings will determine how long the transceiver continues
to wait in the transmit mode for data before reverting to the receive state. The times specied are only
recommendations but will be correct for most applications. If desired, they can be varied to meet specic
data requirements.

Alarm Switch Settings | Optical Fiber | Indicator LEDs
Setting the ALARM DIP (Switch Bank S3)
The third switch bank is used to set the user-congurable alarm feature that indicates the
loss of a data signal. When enabled, the continuous loss of data for more than 1 second will
be sensed and trigger this alarm. This feature will not operate properly in cases where logic
0 or no data bits last for more than 1 second.
To enable or disable the alarm function on the 5018 model, set the ALARM DIP switch as
follows
Transmit Data Signal Position 1: ON = enable OFF = disable
Receive Data Signal Position 2: ON = enable OFF = disable
Optical Fiber Types Supported
Versions of the universal data transceiver are available to drive most multimode (MM) and
single-mode (SM) optical bers. The specic models are identied by a sux at the end of
the model numbers as follows:
Fiber Size Connector 850nm 1300nm
50µ, 62.5µ MM ST -1 -3
8/10µ SM FCPC N/A -7
A 6300 adapter is available to allow the -1 and -3 versions of the 5018A model to be used
with multimode ber and SMA connectors. A 6310 adapter is available to allow
the -7 versions of these models to be used with single-mode ber and single-mode
ST connectors.
Indicator LEDs
The 5018A model has three green signal indicator LEDs that continuously monitor
operation. One, labeled “Power (or PWR)”, lights when operating power is present. The
other two, labeled “Transmit (or Tx)” and “Receive (or Rx)”, turn on whenever the
transmitted or received data is in the “high” state and o when it is in the “low” state.
As a result, they actually blink at the rate of the operating data. However, most data rates
are so fast that these LEDs will usually appear to be on continuously.
The 5018A also has a red LED labeled “ALRM” which lights when an alarm condition
is present.

Conguring a Ring or Loop Data Bus
Conguring a Ring or Loop-Type Data Bus
In addition to point-to-point transmissions, the universal data transceiver can be used to
implement a ring or loop-type data bus. This is accomplished by setting the internal DIP
switches as shown in the following diagram.

Ring or Loop-Type Data Bus Conguration
When the Universal Data Transceiver is used in this mode, any location can receive or insert
data into the ring/loop but only one station at a time is permitted to insert data. All other
stations will receive the data but must maintain their individual input lines in the low state
(RS-232, terminal block position 2 negative with respect to position 1; RS-422, terminal
block position 2, negative with respect to position 3) to prevent loop lock-up. RS-485
operation does not have the above restriction due to the fact that it is in the tri-state mode
when not transmitting.
Note that the rst (or host) location is set to the point-to-point mode. All other locations are
set to the drop-and-repeat mode. This is to prevent loop lock-up or data “echos”.

Considerations
Operating Considerations forFiber Optic Cable
The universal data transceiver may be supplied with ST or FCPC type optical connectors
and will operate with most common ber optic cables. However, it is important to use the
correct type of ber optic cable as required by your particular transceiver model. Some
models (ending in -1 and -3) are designed for use at 850 nm, while others (ending in -7)
function at 1300 nm.
When using any type of ber optic cable, be careful not to cause excessive strains, especially at the cable-to-connector junctions. Also, do not subject the cable to sharp bends or pull
it around sharp corners. Whenever possible, service loops or extra slack should be provided
in any installation. While excessive precautions are not necessary, ber optic cable should
be treated with moderate care as it does contain thin, fragile strands of glass.
Notes Regarding Fiber Optic Cable
Multimode ber optic cable contains an optical ber with a light carrying “core” that is only
.0025 inches (62.5µ) diameter. Single-mode ber optic cable has an even smaller “core”, only
00032 to .0004 inches (8-10µ). This is smaller than a human hair! Any minute particle of dirt
or dust can easily block this ber from accepting or radiating light. As a result, the key word
is cleanliness. Always use the dust caps provided with all optical connectors whenever they
are exposed to air. Also, it is a good idea to gently clean the tip of an optical connector with
alcohol whenever dust is suspected.
Mechanical butt splices or optical feedthroughs must be installed properly. Multimode
devices will not operate properly with single-mode devices even though they may look the
same. Using the wrong device can easily add more attenuation than specied, resulting in
impaired performance.

Operating Pointers
Remember to check attenuation of the ber optic cable. The system will only operate
properly if these specications fall within the range of the system’s loss budget.
Troubleshooting
Multimode ber optic cable contains an optical ber with a light carrying “core” that is
only .0025 inches (62.5 microns) in diameter. Single mode ber optic cable has an even
smaller “core,” only .00032 to .0004 inches (8-10 microns). This is smaller than a human hair!
Therefore, any minute particles of dirt or dust can easily block the ber from accepting or
radiating light. To prevent this from happening, always use the provided dust caps when
ever optical connectors are exposed to air. It is also a good idea to gently clean the tip of an
optical connector with a lint-free cloth moistened with alcohol whenever dust is suspected.
The status of the LEDs should provide the rst clue as to the origin of any operational
failure. If these are o, it usually means that the ber is broken or has too much attenuation.
Next, be certain that the input and output signal connections are correct.
An optical power meter, such as the Fiberlink® 6615, a visible light source, such as the
Fiberlink® 6610, and a Three Wavelength Light Source, such as the Fiberlink® 6620, can
greatly assist and expedite troubleshooting of ber optic transmission systems and are
recommended tools all installers should have available.
Finally, although multimode and single mode devices may look the same, they will not
operate properly together. Using the wrong device or ber can easily add more attenuation
than specied, resulting in poor overall performance. It should be noted that some of our
ber optic products support both single mode and multimode ber in the same unit.
If, after reviewing the above possibilities, the system is still not operating, please contact
the Customer Service Department for further assistance. If you suspect your problem is
caused by the optics or the ber optic cable, and you have an optical power meter, please
take the appropriate measurements prior to contacting support.
