INSTALLATION AND OPERATION INSTRUCTIONS

INTRODUCTION

Thank you for purchasing your American Fibertek 04 Series RS422 data transmitter. Please
take a few minutes to read these installation instructions in order to obtain the maximum
performance from this product.

FUNCTIONAL DESCRIPTION

The 04 Series operates as full duplex transmitter / receiver pair for the transmission of balanced
RS422 data signals over multimode or singlemode fiber optic cable depending upon the model
suffix. Two units are required to make a transmission pair.

MODEL NUMBERS

Model Number Wavelength Fiber
MX-04 850 nm Multimode 50 or 62.5u
RX-04 850 nm Multimode 50 or 62.5u
MX-04-13 1300 nm Multimode 50 or 62.5u
RX-04-13 1300 nm Multimode 50 or 62.5u
MX-04S 1300 nm Singlemode
RX-04S 1300 nm Singlemode

The transmitter converts a single data input into a AM modulated optical output. The standard
model operates at 850 nm, the -13 at 1300nm, both on 50 um or 62.5 um multimode fiber. The –
S model transmits at 1300 nm and is compatible with singlemode fiber. Refer to the data sheets
for detailed performance specifications.

This unit is contained in a compact and rugged aluminum housing with internal dc voltage
regulation. The detachable terminal block and LED indicator provide for easy installation and
monitoring dc power.

The MX is designed for mounting as a modular stand alone unit. For a rack mounted version
please see the RX.

INSTALLATION

THIS INSTALLATION SHOULD BE MADE BY A QUALIFIED SERVICE PERSON AND
SHOULD CONFORM TO THE NATIONAL ELECTRICAL CODE, ANSI/NFPA 70 AND LOCAL
CODES.

Mount the unit to a secure surface using #8 (3mm) hardware in four places. See the drawing on
the next page for mounting dimensions. Be sure to allow sufficient room for the required
minimum bend radius of the fiber cable used.

POWER SOURCE

THIS PRODUCT SHALL BE POWERED BY A LISTED CLASS 2 POWER SUPPLY ONLY.
This unit requires a 12 VDC power source for proper operation. Current draw is approximately

150 mA maximum. In the USA and in Canada an American Fibertek PS-12 is supplied with this
unit. ANSI/NFPA 70 Class 2 wiring is recommended.

POWER CONNECTION

Power is supplied to the unit via a two pin terminal connector. See the customer assembly
drawing for proper location of the 12 volt dc input.

POWER

A green LED indicator monitors the internal dc voltage created within the MT-05B. Power status
associated with this LED is summarized below.

Power Indicator Power Status

Green Voltage Present

Off Voltage Not Present

DATA CONNECTION

The signal connector is a 5 pin detachable terminal block on the rack card (RX) and a 7 pin
combined power and data block on the module (MX) units. Connections should be made
according to the customer assembly drawing. The data input connections pass data to the fiber
optic transmitter Tx port for transmission on the fiber cable. Optical data on the Rx optical port is
present on the Data Output terminals.

FIBER CONNECTION

The fiber optic connection is made via a ST connector located on the side of the unit.

DIP SWITCHES

There are four DIP switches on the unit. Sw1 is used to boost the optical output by
approximately 3 dB. At low fiber loss, the use of this switch may introduce distortions at high
data rates. Only apply this switch with fiber loss of 6 dB or greater.

3

Sw2 determines the output logic state with no fiber connected. This switch must be set to the
same position on both sides of the link for proper operation. For a standard RS422 logic 1 with
no fiber connected, this switch should be Open. This switch may also be used to temporarily
turn on the optical transmitter with no data signal applied to aid in troubleshooting fiber cables or
verify optical output power of the transmitter.

Sw3 and SW4 are not used on these models.
