INSTALLATION AND OPERATION INSTRUCTIONS
INTRODUCTION
Thank you for purchasing your American Fibertek MRM-1485-2F8 multimode mini video
receiver with RS485 transceiver. Please take a few minutes to read these installation
instructions in order to obtain the maximum performance from this product.
FUNCTIONAL DESCRIPTION
The MRM-1485-2F8 operates as half of a transmitter / receiver pair for the transmission of
baseband NTSC, PAL, RS170, or RS343 video signals and bi-directional RS485 data. It is
designed to operate with the MTM-1485-2F8 or RTM-1485-2F8 video transmitter with RS485
transceiver over two multimode fibers.
The MRM-1485-2F8 converts a FM modulated optical fiber input into a single video output and a
single RS485 output using an 850 nm wavelength detector. The MRM-1485-2F8 also converts
an electrical RS485 input signal into an optical RS485 output returning on a separate fiber using
an 850 nm wavelength source. This unit may be configured for two wire half duplex or four wire
full duplex electrical interfaces. The M1485-2F8 Series product is designed to operate over an
optical loss budget range of 0 to 12 dB. The MRM-1485-2F8 operates on 50 um or 62.5 um
multimode 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 indicators provide for easy installation and
monitoring of video, data, and dc power.
The MRM-1485-2F8 is designed for mounting as a modular stand alone unit. For a rack
mounted version please see the RRM-1485-2F8.
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.
The unit requires a +12VDC power source for proper operation. The DC input is diode
protected. In the USA and in Canada an American Fibertek PS-12 is supplied with this unit. The
negative side of the power input is directly connected to ground. ANSI/NFPA 70 Class 2 wiring

2F8 or RTM-1485-2F8. The reverse flow follows the same orientation.
VIDEO OUTPUT CONNECTION
The video output connection is made via a BNC connector on the right side of the unit. The 75Ω
video output can be looped through typical baseband video inputs of switchers, recorders and
other equipment as required. For proper operation, the output must be terminated with 75Ω. For
optimum performance the video cables should be the shortest length of coax practical.
DATA INPUT / OUTPUT CONNECTIONS
Data input and output connections are made via a terminal block on the right side of the unit.
Follow label on unit for proper orientation of RS485 data input and output. Please note that two
wire applications utilize the four wire Data Out + and Data Out - terminals. Also note that in four
wire installations Data In on the MRM-1485-2F8 becomes Data Out on the MTM-1485-2F8 or
RTM-1485-2F8 after going across the fiber. The reverse flow follows the same orientation.
DATA CONFIGURATION
The MRM-1485-2F8 is shipped from the factory in the RS485 4-wire configuration. In order
to configure the unit for RS485 two wire operation, the unit needs to be opened up and
several switch settings and jumper pins need to be modified using the internal
switch/jumper settings shown on the next page.
The MRM-1485-2F8 is shipped from the factory with internal data input and output 120

RS485 TERMINATIONS
The RS485 protocol is an expanded version of the original RS422 protocol. The RS485 protocol
is an expanded version of the original RS422 protocol. RS485 differs from RS422 in the ability
of the transmitter devices to go into a high impedance (Hi-Z) state. This allows multiple
transmitter devices to reside on the same wire pair. The software must dictate a protocol that
allows one device to transmit at any one time to prevent data crashes. Data wiring can use two
wires or four wires. Using two wires the system works in half duplex. This means that data is
exchanged between two points sequentially. When a four-wire system is used, the system may
be full duplex. In many cases the system head end controller will continuously poll data from all
remote devices. The remote devices all respond back to the head end (one at a time!) as they
are addressed. This property of the network rests solely in the hands of the software or
firmware.
The driver chips used in RS485 communications are capable of changing into their high
impedance state very rapidly. On even short lengths of wire there can exist a residual voltage
after a driver circuit turns off. This can interfere with circuits that are used to detect the Hi-Z
state. It is very important that the copper communications lines be terminated with resistors
across the data wire pair. The best place to locate such resistors is at the furthest electrical
devices at the ends of the wire pair. For instance, if several RS485 devices are connected in a
daisy chain fashion, the wire connection would loop across all devices in a chain. The furthest
two points in the chain would need to be terminated. A termination resistor for RS485 input data
can be selected in the MRM-1485-2F8 using switch # 1. A termination resistor for RS485 output
data can be selected in the MRM-1485-2F8 using switch # 2.
OFFSET BIAS – RS485
The RS485 specification requires receivers to detect input signals down to 200mVp-p of voltage
level. In many cases this can cause systems to be sensitive to noise on the data wires. In an
effort to eliminate the effects of low levels of noise, some manufacturers of equipment that
communicate using RS485 have introduced a small voltage bias to the data lines. This is
usually accomplished using 470 Ohm resistance to +5V on the positive line and 470 Ohm
resistance to ground on the negative line. When used in conjunction with the appropriate
termination resistors referred to in the previous section, this introduces about a 300 mV offset,
improving noise immunity.
Offset bias for RS485 can be applied on the MRM-1485-2F8 by setting switch # 3 and switch #
4 on. Please note that these switches work as a set and must be either both on or both off. In a
majority of cases, bias will not be required and these switches should remain in the off position.
If using offset bias, it is important that termination resistor switch # 2 be on (applied) position.
Using offset bias without a termination on the line will cause communications to fail.
