Precautions
Important Safety Warnings
[Power]
Operate unit only on the specified supply voltage.
Disconnect power cord by connector only. Do not pull on cable portion.
Do not place or drop heavy or sharp-edged objects on power cord. A damaged cord
can cause fire or electrical shock hazards. Regularly check power cord for
excessive wear or damage to avoid possible fire / electrical hazards.
[Grounding]
Ensure unit is properly grounded at all times to prevent electrical shock hazard.
Do not ground the unit to gas lines, units, or fixtures of an explosive or dangerous
nature.
Ensure power cord is firmly plugged into AC outlet.
[Operation]
Do not operate unit under hazardous or potentially explosive atmosphere
conditions. Doing so could result in fire, explosion, or other dangerous results.
Do not allow liquids, metal pieces, or other foreign materials to enter the unit. Doing
so could result in fire, other hazards, or unit malfunction.
If foreign material does enter the unit, turn the power off and immediately
disconnect the power cord .Remove the material and contact an authorized service
representative if damage has occurred.
[Transportation]
Handle with care to avoid impact shock in transit, which may cause malfunction.
When you need to transport the unit, use the original or adequate packing material.

[Circuitry Access]
Do not remove covers, panels, casing, or access the circuitry with power applied to
the unit! Turn the power off and disconnect the power cord prior to removal. Internal
servicing / adjustment of unit should only be performed by qualified personnel.
Do not touch any parts / circuitry with a high heat factor.
Capacitors can retain enough electric charge to cause mild to serious shock, even
after the power has been disconnected. Capacitors associated with the power
supply are especially hazardous. Avoid contact with any capacitors.
Unit should not be operated or stored with cover, panels, and / or casing removed.
Operating unit with circuitry exposed could result in electric shock / fire hazards or
unit malfunction.
[Potential Hazards]
If abnormal odors or noises are noticed coming from the unit, immediately turn the
power off and disconnect the power cord to avoid potentially hazardous conditions.
If problems similar to the above occur, contact an authorized service representative
before attempting to operate the unit again.
[Rack Mount Brackets, Ground Terminal, and Rubber Feet]
To rack-mount or ground the unit, or to install rubber feet, do not use screws or
materials other than those supplied. Otherwise, doing so may cause damage to the
internal circuitry or components of the unit. If you remove the rubber feet that are
attached to the unit, do not reinsert the screws securing the rubber feet.
[Consumables]
Consumable items that are used in the unit must be periodically replaced. For
further details on which parts are consumables and when they should be replaced,
refer to the specifications at the end of the Operation Manual. Since the service life
of consumables varies greatly depending on the environment in which they are
used, such items should be replaced at an early date. For details on replacing
consumable items, contact your dealer.

1. Prior to Starting
1-1. Welcome
Congratulations! By purchasing MFR-1616/MFR-1616R/MFR-3216/MFR-3232/MFR-1616A
Multi Format Routing Switcher (hereafter called MFR main unit) you have entered the world of
FOR-A and its many innovative products. Thank you for your patronage and we hope you will
turn to FOR-A products again and again to satisfy your video and audio needs.
FOR-A provides a wide range of products, from basic support units to complex system
controllers, which have been increasingly joined by products for computer video based systems.
Whatever your needs, talk to your FOR-A representative. We will do our best to be of continuing
service to you.
1-2. Features
The MFR-1616, MFR-1616R, MFR-3216, MFR-3232, and MFR-1616A comprise a group of
multi-format routing switchers with a variety of input/output numbers supporting 3G-SDI,
HD-SDI, SD-SDI, ASI, and AES (MFR-1616A only) signals. In the compact body, the units have
inherited various functions of the MFR-5000 such as the capability of linking multiple cases, tally
connections with peripheral devices, and automatic source name tracking, to allow the units to
be the core product in small to medium size systems.
Support for 3G-SDI, HD-SDI, SD-SDI, ASI, and AES (MFR-1616A only) signals with
automatic signal recognition that enables operation without concern for the type of signal.
Various crosspoint control functions such as Salvo, Take, Link, Level operation, and Chop
Tally linking with FOR-
displays on video switchers and multi viewers can be switched in conjunction with switchings
controlled in the main unit. MFR routers support TSL and Harris protocol, enabling linkage to
other companies' products.
Built-in webserver for remote control through a web browser
SNMP support enabling SNMP monitoring system configuration
Status monitoring for power supply, fan, CPU, SDI input/output, etc.
CPU board redundancy (MFR-SRCPU option) allowing monitoring of primary CPU board
operation via the secondary board
Immediate and smooth switch over to the secondary board without down time in case of
irregularities, as well as stable remote control operation supported by the network
redundancy (Supported by MFR-SRCPU option)
Power unit redundancy for stable power supply against power unit failure or power supply
troubles
Matrix partition and level setting capabilities support a flexible control environment
Remote control over a main unit from multiple remote control panels (maximum of 128 units
can be connected in total including the main unit)
Remote control panel connectivity for configuring a huge control panel
Interface expansion unit (MFR-GPI) for additional 128 (32 x 4) GPI/O and 4 serial ports (9-pin
D-sub, male)
MFR-TALM Tally Manager Unit is designed specifically to manage tally and signal name data
in the MFR system and the exchange of this data with external devices such as a video
switcher, multiviewer etc.. The unit performs the task of tally data computation, which is
ordinarily undertaken by the MFR main unit, to accelerate the task.

*1 The MFR-LAN/MFR-LAN(CPU1, 2) connector may be labeled as TO RU, and the PC-LAN
connector as TO PC on units shipped before Sep. 16, 2011.
*2 The SERIAL connector is set to RS-232C as factory default. Consult your FOR-A reseller if
you wish to change the setting.
IMPORTANT
The MFR-LAN/MFR-LAN (CPU1, 2) ports must be connected to a LAN to enable
operation. The LAN connections for MFR Series devices must be separated from the
network segment of other devices.
When Installing MFR-SRCPU
Installing the MFR-SRCPU card enables MFR-1616R/MFR-3216/MFR-3232 units to have
redundant CPU cards and Ethernet ports, which can be used for remote control panel
connection.
