Distance specications are only approximate and are not guaranteed. Loss budget must not be exceeded.
* Note that as provided from the factory, the universal data transceiver is set to the RS-232 point-to-point
(200 kbps) and low speed modes of operation.
In the low speed mode the unit will operate with all duty cycles including DC (logic 0 or logic 1
continuously). In the high speed mode of operation, the system will operate properly with all duty cycles
from 50-50% to 70-30%.
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.

Fiberlink® 5018A 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 conjunc-
tion 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 alter-
native, the unit may be automatically switched from transmit to receive by means of an
internal data-driven timer (Data-Derived T/R switching).

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.
Installation
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!

Modes of Operation:
On the 5018A card-cage model, there are three DIP switch banks located on the
printed circuit card. Switch Bank S1 sets the Mode of Operation, Switch Bank S2
sets the Baud Rate (RS-485 Data Format) and Switch Bank S3 sets the Alarm.
Setting the MODE DIP switch
Switch setting example
Low Speed or High Speed Operation:
For all protocols, positions 1 and 2 of the MODE DIP switch (S1) MUST be set
as either Low Speed or High Speed Operation as follows:
Low speed mode (DC to 2.1 mbps):
Position 1 = ON, Position 2 = OFF
High speed mode (10 kbps to 10 mbps):
Position 1 = OFF, Position 2 = ON
For RS-232, the data rate is limited to 200 kbps. For RS-422/485, the data rate is as above.
The universal data transceiver will not operate properly if positions 1 and 2 are both set to either ON or OFF.
