Product Description
4 Product Description
4.1 Use and Application
The optical data coupler serves as an optical link between two Ethernet devices;
ideally, one of these devices is mobile. The opening angle is optimized for
operations in high-rack storage.
Devices in industrial Ethernet networks (e.g., with PROF NET, EtherNet/ P, and
other Ethernet protocol designs) can be connected to the optical data coupler.
The physical transfer takes place with 100 MBit/s full duplex. The connection to
multiple devices must be implemented using switches that have been certified for
use with the bus system in question. All layer 2 telegrams ( EEE 802.3 Clause 25)
are physically transported. There is no saving of telegrams, so the transfer is not
delayed at all.
Devices with a transfer rate of 10 MBit/s can be connected via a switch.
The optical data coupler uses a semiconductor laser as an optical emitter. The
dilation of the light beam and the use of return map blocks guarantee that the
devices are harmless in accordance with laser class 1M. The emitted beam must
not be viewed with telescopes or binoculars from distances of less than 20 m. At
longer distances, the limit values for laser class 1 are not exceeded, even when
viewed through a telescope with a 50 mm aperture.

nstallation
Mounting on a P+F A justment Device
The mounting accessories (OMH-LS610-01) consist of a mounting bracket and
an integral alignment device (in x and y axes). The required beam direction (± 90°
rotation) can be set using the mounting accessories, which are fastened to the
mounting bracket using two M4 screws and the central M6 screw. The central
screw is for securing the unit in place following adjustment and should not be
tightened until the adjustment is finalized. To mount the optical data coupler,
squeeze the two front levers together and place feet into the four openings in the
adjustment device. The feet have to lock into place so that the levers can be
released outwards as far as the stop; if necessary the optical data coupler has to
be pressed down applying some force from the top to the center.
5.3 Connection
Connecting the Supply Voltage
The device conforms to protection class . This means that the power has to be
supplied as a low protective voltage (PELV) and limited according to UL Class 2
(100 W). The optical data coupler is supplied with a direct voltage of
18 VDC ... 30 VDC. The insulation test voltage (shield against power/GND) is
50 V maximum.
To supply voltage to the device, proceed as follows:
1. Plug the prepared connecting cable with the 4-pin M12 socket into the plug
provided on the rear of the housing.
2. Screw the cap nut onto the connector as far as it will go. This ensures that the
power cable cannot be inadvertently pulled out.
3. Now connect the supply voltage to the cable provided.
The device is now ready for operation.
Grounding/Shielding
This type of grounding is not protective grounding, it acts solely as a down
conductor for cable-related faults and is not subject to any safety guidelines (e.g.,
personnel protection). Functional grounding of the cable shields is required to
provide immunity to interference.
To ground the device, proceed as follows:
1. Make up a ground cable using a 6 mm flat connector with an adequate cross-
section (≥1.5 mm²).
2. Plug the flat connector onto the pre-mounted insertion prong on the device.

LS682-DA
nstallation
2015-05
17
3. Connect the other end of the ground cable to adjacent metal components
(e.g., mounting base, frame, etc.).
The device is now grounded.
Establishing the Network
The M12 plug (D coded) on both devices features the standard assignment for
Ethernet. The optical data coupler automatically locates transmitting and
receiving lines (Auto-MD X), meaning there is no need to use a crossover cable.
To connect the device to a network, proceed as follows:
1. Plug the prepared network cable with the 4-pin M12 plug into the socket pro-
vided on the rear of the housing.
2. Screw the cap nut onto the connector as far as it will go. This ensures that the
power cable cannot be inadvertently pulled out.
3. Now connect the network cable to the network connection provided for this
purpose.
The device is now ready for operation.
5.4 Storage and Transport
For storage and transport purposes, package the unit using shockproof
packaging material and protect it against moisture. The best method of protection
is to package the unit using the original packaging. Furthermore, ensure that the
ambient conditions are within allowable range.
Note!
The Ethernet cable must be of CAT5 quality as a minimum.
Unshielded cables (UTP) are not suitable for maintaining immunity.

6.1 Alignment and Adjustment
Aligning two devices over long distances is difficult and is almost impossible to
achieve if working alone. However, optimal alignment of the devices and the
highest possible reception level are crucial for faultless data transfer. The new
"bidirectional" display mode of the LS682 optical data coupler helps with this
process.
There are two display modes to help you with adjustment:
■Unidirectional: suitable for short distances up to approx. 150 m
■Bidirectional: suitable for long distances from 150 m to 300 m
Alignment Ai s in "Uni irectional" Display Mo e
To make alignment easier, an alignment LED that is visible from far away is
located on the front of the device. As soon as a receiver detects the emitted light
of the device opposite it, the flashing frequency of the alignment LED decreases.
When the alignment LED goes out, the devices are optimally aligned. Sufficient
excess gain is available.
Figure 6.1 Position of the alignm ent LED and the bar graph display on the device
The bar graph indicator shows the reception level of the device on which it is
located.
Tip
The optical data coupler is designed to ensure that an adequate reception level is
obtained over the entire emitter spot. However, for technical reasons, the
maximum reception level is often not in the center of the spot. To ensure that the
range is as symmetrical as possible, Pepperl+Fuchs recommends using the
adjustment aid to "trace" the edges of the spot horizontally and vertically, and then
setting the center position. The drop-off in intensity at the edge of the spot is very
pronounced, which makes the edges easy to locate.

Figure 6.2 Explanation of relationship between bar graph display and operating state
Excess Gain
n "Excess gain" mode (green zone), the signal strength of the optical data coupler
is sufficient for operational purposes. The optical data coupler should operate in
the green zone within the nominal range (at least one green LED); if the signal
strength drops below this limit level, the weak signal indication (alarm output) is
switched off. Telegrams continue to be sent until the signal strength drops below
the level required for operational purposes (red LED only).
Alignment Ai in "Bi irectional" Display Mo e
The reception level of both sides is shown at the same time on one device.
This means that the effect on the reception of both devices when aligning can be
read directly on the device. t is no longer necessary to have someone helping on
the opposite side.
The "bidirectional" display mode starts automatically when the LS682 optical data
coupler has not received any signal for more than three seconds (e.g., due to
interruption of the light beam with opaque material or deliberate covering of the
receiving lens).
n the "bidirectional" display mode, the highest reception level value is displayed:
■Steady LED: reception level of the local device.
■Flashing LED: reception level of the opposite device.
The "bidirectional" display mode is ended if the signal level on both sides is stable
and greater than the minimum reception strength for more than eight seconds.
