2. There are only TA and RA for multimode product, and can transmit 2km.
INSTALLATION
Installation of video interface
To install the apparatus, it is necessary to allow enough space to accommodate the bend
radius of the optical cable connected to it. The transceiver requires practical BNC terminated
coaxial cables to input/output the video signals.
Installation of card unit
Push the card unit along the guide rails (not in spaces between the rails). There is an Infinova
logo on the front panel indicating the proper orientation. Press hard to make good connection
to motherboard - loud snap indicates firm connection. There are two captive screws on the
front panel that can fasten the card unit to the sub-rack. They must be locked by hand in a
clockwise manner (do not over tighten).

Full load of N3910-18S
There are 18 slots on N3910-18S. So it can mount 18 pieces of card unit. Besides
N3910-18S, there are N3910-1S, N3910-2S, N3910-3S, N3910-4S and N3910-15R optional.
There are 1 slot on N3910-1S, 2 slots on N3910-2S, 3 slots on N3910-3S, 4 slots on
N3910-4S and 15 slots on N3910-15R respectively.
WARNING:
A FULL LOAD OF N3910-15R AND N3910-18S SUBRACK REQUIRES FORCED AIR COOLING IN
THE RACK. TO AVOID OVER HEATING OF CARD UNITS, WHENEVER POSSIBLE, INSTALL IN
EVERY OTHER SUBRACK.

POWER SUPPLY
Power supply for card unit
The unit is powered by a plug-in power supply that is offered with the appropriate desk
chassis or EIA 19" subrack.
Power supply for stand-alone module
The card unit can be converted into a stand-alone module when installing into a 1-slot
chassis N3910-1S (for N3742&N3542series, and N3744&N3544 series) or 2-slot chassis
N3910-2S (for N3746&N3546series, and N3748&N3548 series), that is powered by a
plug-in 24VAC@1A (N3921-24A-1 for 120V; N3921-24A-2 for 230V) or 12VDC@1A
(N3921-12D-1 for 120V; N3921-12D-2 for 230V) power supply. Plug the wires into the
connectors, fasten the screws to make a firm connection, see figure below.

and power supply
Note:
When the series is powered together with other devices (cameras and etc.) by a single
24VAC power source, please make sure that the related device has a full-wave (bridge)
rectifier circuit.
