PELCO's WLV500 Series wireless control link system  
is designed to provide wireless remote control of cam-  
era positioning and zoom functions. The system is  
compatible with coaxitron remote control systems such  
as a PELCO Coaxitron System 2000 and operates in  
conjunction with the WLV1000 wireless video sys-  
tem.

4. The units should become fully operational  
within two minutes after DC power is con-  
nected, after which adjustments can be made.  
ThemaximumtransmissionrangeforboththeWLV1000  
and WLV500 will be achieved when there is a clear line  
of sight between the transmitter and receiver antennas.  
Thebestreceptionwilloccurifallantennasareelevated  
a minimum of 8 to 10 feet above level ground. If there  
aremovingobjectsbetweentheantennas,suchastraffic  
on the road, the antennas should be elevated a minimum  
of 8 to 10 feet above such objects to obtain the best  
reception .  
4.2 ANTENNA POSITIONING AND  
MOUNTING  
Althoughthevideoanddatasystemsoperateatdifferent  
frequencies, out of band emissions exist due to the  
wideband transmission characteristics of the video sig-  
nal. At the maximum operating range these out of band  
video emissions can have a higher signal strength than  
thereceiveddatasignalduetothecloseproximityofthe  
WLV1000TX to the WLV500RX. This will “jam” the  
WLV500RX receiver preventing reliable operation. To  
preventjammingandachievereliableoperationatmaxi-  
mum range the WLV500RX antenna must be located a  
minimum of 4-5 feet from the WLV1000TX antenna.  
The distance between the WLV500TX and  
WLV1000RX antennas is not critical, since the narrow  
band emissions of the WLV500TX will not noticeably  
affectthereceivedvideosignalfromtheWLV1000RX,  
but it is recommended to maintain at least 10 inch  
separation.  
For units that have a detachable antenna on the receiver,  
only a high quality, low loss 50 ohm cable (RG-8 or  
similar) should be used for situations requiring a longer  
interconnection between the receiver and antenna. It is  
alsobesttopositiontheantennasuchthatthefrontofthe  
antenna is directly facing the transmitter, and is not  
obstructed by any metallic objects.  
Forlargeseparations, itisrecommendedthatatwo-way  
voice communication device be used to best position  
the transmitter and receiver. When a suitable location is  
found, the mounting brackets should be used to secure  
the units in place.

2. Interference  
4.3 TROUBLESHOOTING  
The WLV500 Series transmit in the 2.4 GHz  
band. Although this band is less crowded than  
the 900 MHz band, it is still susceptible to  
some outside interference, including mobile  
video transmission. Most interference should  
be very temporary, but if consistent interfer-  
ence occurs there are 3 channels that are avail-  
able. At no cost to the user, the unit can be  
replaced by a system that operates in another  
channel.  
It is recommended that the wireless transmission con-  
trol link system be first tested with both the WLV500  
and WLV1000 transmitters and receivers in close prox-  
imity (3 to 6 feet), to ensure proper interconnection of  
the coaxitron receiver and transmitter with the wireless  
transmitters and receivers. If all interconnections are  
made appropriately as described, there should be unin-  
terrupted remote control of the pan and tilt device. If  
there should be difficulties at this point then:  
1. Check the performance of the system minus  
the wireless control link transmitter and re-  
ceiver by directly connecting the coaxitron  
transmitter to the coaxitron receiver. This will  
verify the performance of the coaxitron sys-  
tem, as well as verify that the interconnecting  
cables are good.  
3. Multipath Reception (Ghosting)  
SincetheWLV500SeriesemploysFMmodu-  
lation of the data onto the carrier it is less  
susceptibletomultipathinterferencethancom-  
mercial broadcast systems that employ ampli-  
tude modulation. The WLV500 system also  
employs circularly polarized antennas that  
provide some immunity to multipath reflec-  
tions. However, multipath interference can  
occur and depends on antenna location rela-  
tive to nearby metallic objects, and on the  
direction the antenna is facing. The receiver  
antenna provides the most gain and highest  
multipath immunity when it is directly facing  
the transmitter. If multipath interference oc-  
curs, it can usually be eliminated by relocating  
or reorienting the receive antenna a small  
distance (less than 1-2 feet).  
2. If the verification detailed in (1) above is  
performed and the system is fully reconnected  
and there is still not full control, check the  
power supply voltage. If the voltage out of the  
supplyislessthan12.0volts, thepowersupply  
needs to be replaced. Please contact PELCO  
for a replacement.  
3. If the system is still not operating after  
successfully verifying the steps above, the  
fault must lie within the wireless control  
link system. Please contact PELCO imme-  
diately for a replacement. It is our policy to  
provide quality products to our customers.  
Note: Due to the difficulty of predicting the suscep-  
tibility of any one application to the transmis-  
sion limitations described above, it is gener-  
ally recommended that site testing occur prior  
to installation. Consult your customer service  
representative to obtain further information.  
If the transmitter and receiver are now placed in their  
required locations and there is intermittent control fail-  
ures on the pan and tilt, there are several possible  
reasons that need to be addressed individually.  
1. Exceeding Maximum Range  
The base models of these units are specified to  
operate at 1,000 feet maximum line-of-sight  
distance. Obstructions between the transmit-  
ter and receiver antennas will reduce maxi-  
mum range. The maximum distance will vary  
depending on the type and number of obstruc-  
tions encountered. If the operating distance is  
nearing 1,000 feet, then we recommend an  
upgrade to the receiver antenna.
