FCC ID: MD5-SM02
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to part 15 of the
FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential
installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in
accordance with the instructions,
may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be
determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one or more of
the following measures:
—Reorient or relocate the receiving antenna
—Increase the separation between the equipment and receiver
—Connect the equipment into an outlet on a circuit different from that to which the receiver is connected

1 Introduction
This document will provide a brief description on how the VDS-POD-S is being used within FCC limitations. VDS-POD-S
contains a configurable, high performance, simple to use 902-928 MHz radio. VDS-POD-S has the capability to transmit at
20 dbm, and an in-built low noise amplifier in the receive path for extended range. The VDS-POD-S is being used as a
configurable magnetic sensor.

1.4 VDS-POD-S Installation Considerations
Care shall be taken to insure that the Sensor housing is not punctured or crushed. The sensor contains a Lithium Thionyl
Chloride battery and certain precautions shall be taken. Dispose the sensor housings with batteries in accordance with local
regulations.
A label is affixed on the top of the sensor which contains a unique ID and an arrow for the direction of traffic flow. The
unique ID is used for configuring the system so the Access Point only talks to the sensors at this specific location and not
Access Points nearby at other intersections. Record the ID of each sensor and their location for use when configuring the
User Interface.
1.4.1 Equipment needed:





Coring Drill with 4” diamond bit. Water is needed for the core drill to cool the bit during drilling.
Chisel for cleaning the hole out.
Shop Vacuum for removing the debris out of the hole after core is removed.
Propane torch to dry out the hole before sealant is applied.
Epoxy, a two part Joint sealant. Fabick Joint sealant is recommended.
1.4.2 Installing the VDS-POD-S in the road
IMPORTANT: Safety glasses are required at all times.
A manufacturers label is affixed on the top of the VDS-POD-S which contains an arrow for the direction of traffic flow.

Mark the area of the desired VDS-POD-S location.
Core a hole approximately 4.0” diameter and 2.75” deep into the pavement.
Remove any debris with chisel to clean out the hole.
Dry hole with propane torch to remove any moisture.
Fill hole with approximately 1” of sealant and place VDS-POD-S in hole with arrow pointing with the flow of
traffic.
Add sealant to completely cover the VDS-POD-S.
Maintain VDS-POD-S level about 0.25” from the road surface until sealant dries in approximately 3 minutes.
