5.2 Precautions before connection
■
For installation
● If connecting a cable to the FDX or an external device that connected to the FDX, touch grounded metal to
remove electricity from your body before holding the cable.
● Do not block vent holes.
Keep 30 mm/1.18 inches or bigger space from the FDX.
● Do not install the FDX in a closed space.
If you must install the FDX in a closed space (EIA rack mount), install an additional ventilation space in
order to keep the ambient temperature at 40 degrees C/104 degrees F or less. If inadequately vented, the
life of parts may be shortened and operations may be affected.
■
Cabling
● Read manuals of the external devices.
● Turn off devices and then connect them.
● Be sure to plug cables in completely and install them without any stress on connectors.
■
Attaching rack mounting brackets
1.
Remove two M5 screws from one side of the unit. Retain the screws for step 2.
2.
Attach one bracket to the side of the unit using the screws removed in step 1.
3.
Repeat steps 1 and 2 on the other side of the unit.
Note : The standard screw tightening torque is 2.94 N

HDBaseT cable <Read the following precautions when installing an HDBaseT I/O slot board.>
Even though the connector for a long-distance transmission is the same as eight-core connector that is
used for Ethernet, the transmission method is different. As a result, the connector for a long-distance
transmission cannot be connected to Ethernet.
Please use a correct HDBaseT cable and install it correctly to maximize the performance of this product.
● We recommend a Cat6 UTP/STP cable for the HDBaseT cable between the transmitter and receiver.
If using an STP cable, connect the FG connector to an earth ground source. Otherwise, the shielding
function does not work correctly. When using a UTP cable, we still recommend that you use the ground
connector.
● For 50 m/164.04 feet or shorter transmissions, Cat5e UTP/STP cable also can be used.
● The shielded STP cables are less affected by interference or external noise than UTP cables.
● The maximum extension distance of Cat5e/Cat6 UTP/STP cable is the shortest maximum extension
distance of the connected HDC transmitter, HDC receiver and sink device.
● For pin assignments, apply T568A or T568B straight through cabling.
● Do not give connection cables a strong pull. The allowable tension of the HDBaseT cable is 110 N.
● Do not bend the connection cable at a sharp angle. Keep the bend radius four times of the cable
diameter or more.
● Keep the HDBaseT cable as straight as you can. If you coil the cable, it is easily affected by noise.
● Do not tie the cable tightly; leave a space allowing the cable to move slightly.
● If you use the same cables, we recommended keeping distance between the cables or not to place
the cables closely in parallel.
● Do not place this product in an electrically noisy environment, since high-speed signals are transmitted.
Video or audio may be interrupted especially when you use a high-output radio around the FDX.
